Overview

What this SWMS covers

Equipment assembly and installation represents a broad category of construction activities involving mechanical equipment, plant, and systems installed in buildings, industrial facilities, and infrastructure projects. The scope encompasses substantial diversity from small items including retail display fixtures and office furniture through to major plant installations including chillers, boilers, industrial machinery, and process equipment weighing multiple tonnes requiring crane placement and complex foundation connections. Installation work typically follows a sequence including delivery receipt and unpacking, transport to installation location, positioning on foundations or mounting points, assembly of components, securing to structures, connection of utilities including electrical, water, gas, and data services, and commissioning involving testing and adjustment to achieve operational performance. Industrial equipment installation supports manufacturing, processing, and production facilities requiring machinery capable of performing specific industrial processes. This includes production line equipment, processing machinery, material handling systems, compressors and pressure vessels, packaging equipment, and automated systems with integrated controls and safety interlocks. Industrial installations often involve equipment manufacturers' technicians working alongside construction contractors to ensure correct assembly following precise specifications and alignment tolerances. Equipment may arrive in multiple shipping containers requiring careful inventory management, logical assembly sequencing, and coordination with building construction to ensure adequate access for delivery and installation. Foundation preparation including concrete pads, anchor bolt installation, and vibration isolation systems must be completed before equipment delivery with dimensional accuracy ensuring equipment mounting aligns correctly. Building services equipment installation provides mechanical systems supporting building operations including HVAC equipment, pumps, water treatment systems, emergency generators, and electrical distribution equipment. This work typically occurs during building construction or major refurbishment projects requiring coordination with structural, electrical, and hydraulic trades. Rooftop equipment installations including chillers, cooling towers, and air handling units present additional challenges with height access requirements, weather protection during installation, and crane lifting to elevated positions. Plant room installations occur in confined spaces with multiple concurrent trade activities requiring careful work sequencing and temporary equipment access solutions. Equipment mounting must accommodate thermal expansion, vibration isolation, and maintenance access requirements whilst meeting structural loading limits and building services coordination constraints. Commercial equipment installation serves retail, hospitality, healthcare, and institutional facilities including commercial kitchen equipment, refrigeration systems, laundry equipment, fitness equipment, medical devices, and laboratory equipment. These installations frequently occur in operating facilities requiring work scheduling to minimise disruption, implementation of additional safety controls protecting building occupants, and enhanced cleaning and hygiene protocols particularly in healthcare and food service environments. Equipment specifications often mandate specific installation requirements including ventilation, drainage, electrical supply characteristics, and clearances for operation and maintenance. Commissioning and handover processes may involve extended testing periods, operator training, and documentation of operational parameters meeting manufacturer warranties and building compliance certifications. Equipment specifications and manufacturer requirements significantly influence installation procedures and safety considerations. Equipment manuals provide critical information including weight and centre of gravity for lifting operations, lifting point locations and load limits, assembly sequences ensuring structural integrity during progressive assembly, torque specifications for fasteners affecting structural connections, utility connection requirements including electrical characteristics and fluid specifications, clearance requirements for ventilation and maintenance access, and commissioning procedures including testing sequences and safety checks. Deviation from manufacturer specifications may void equipment warranties, create safety hazards from incorrect assembly, and prevent equipment achieving design performance. Installation contractors must maintain manufacturer documentation on site, brief workers on specific requirements, and document compliance with installation specifications. Foundation and mounting preparation demands precise dimensional control ensuring equipment interfaces correctly with building structures and utilities. Concrete foundations require correct dimensions, anchor bolt positioning within tight tolerances, adequate curing before loading, and surface flatness meeting equipment specifications. Structural steel mounting frames must align correctly, possess adequate load capacity for static and dynamic equipment loads, and provide adjustment capability for equipment alignment. Floor-mounted equipment requires assessment of slab loading capacity, identification of existing services beneath slabs preventing anchor damage, and verification of floor flatness and level within equipment tolerances. Wall-mounted equipment installations verify wall construction adequate for mounting loads, identify structural framing for secure attachment, and provide backing or reinforcement if wall construction inadequate for direct mounting. Utility connections including electrical, water, gas, compressed air, and data services require coordination with service trade contractors and compliance with relevant codes and standards. Electrical connections must be performed by licensed electricians following AS/NZS 3000 wiring standards, implement appropriate circuit protection and earthing, and verify supply characteristics match equipment requirements. Water connections require backflow prevention if equipment could contaminate water supply, adequate pressure and flow rates for equipment operation, and drainage provisions for equipment servicing and emergency relief. Gas connections require licensed gasfitters, leak testing before commissioning, and emergency isolation valve accessibility. Compressed air systems require adequate pressure regulation, moisture removal, and connection fittings compatible with equipment ports. Data and control connections implement cable management preventing damage, appropriate cable types for signal characteristics and environmental conditions, and testing verifying signal integrity.

Why this SWMS matters

Equipment installation incidents cause serious injuries annually across Australian construction and industrial sectors, with manual handling injuries, crush injuries, and electrical incidents representing primary injury mechanisms. The diversity of equipment types, installation locations, and commissioning procedures creates varied hazard profiles requiring systematic risk assessment rather than reliance on generic procedures inadequate for specific equipment characteristics. Many equipment installation workers transition between different equipment types and work environments without adequate briefing about specific hazards, relying on experience with dissimilar equipment that may not transfer appropriately to current installation requirements. Manual handling injuries dominate equipment installation incidents, affecting workers who lift heavy components, work in awkward postures during assembly, maintain overhead positions during mounting operations, and push or pull equipment during positioning. Commercial kitchen equipment, industrial machinery components, and building services equipment often weigh 50-200 kilograms per component requiring mechanical lifting aids or team lifting, yet workers frequently attempt manual handling using inadequate techniques under schedule pressure. Repetitive lifting during assembly of multi-component equipment creates cumulative trauma even when individual components are within safe manual handling limits. Overhead work installing elevated equipment including wall-mounted air conditioning units and high-mounted industrial equipment causes shoulder and neck strain from sustained overhead arm positions. Poor workspace layout during assembly requires workers to reach, twist, and bend to access components and fasteners creating back strain and postural injuries. These injuries typically result in chronic pain conditions, reduced work capacity, and sometimes permanent disability preventing continued equipment installation work. Crush and pinch injuries occur when equipment shifts during positioning, assembly operations trap hands and fingers between components, equipment falls from unstable temporary supports, or inadequately secured equipment tips during connection work. Multi-tonne industrial equipment positioned using jacks, rollers, or skates may shift unexpectedly if ground conditions are uneven, equipment centre of gravity is misjudged, or movement control is inadequate. Workers' hands and feet are trapped between equipment and foundations during final positioning as workers attempt to make minor adjustments without proper spacing tools or mechanical positioning aids. Equipment supported on temporary timber blocking topples if blocking configuration is unstable or load distribution is uneven. Partially assembled equipment lacks structural integrity of completed assemblies creating collapse hazards if workers rely on incomplete structures for support or access. Investigation of serious crush incidents consistently identifies rushed positioning operations, inadequate temporary support design, and workers placing body parts in pinch points without verifying equipment is secured. Electrical incidents during equipment commissioning and testing occur when workers energise equipment before electrical installation is complete, work on energised equipment during troubleshooting, or make electrical connections without verification of isolation. Equipment may arrive with internal wiring completed requiring only supply connection, but workers unfamiliar with equipment assume all electrical work requires licensed electricians when some connection activities fall within mechanical trade scope creating confusion about work boundaries. Energising equipment for testing before mechanical assembly is complete creates unexpected movement hazards when electrical interlocks are bypassed for testing purposes. Troubleshooting equipment failures during commissioning may involve working on energised control circuits creating electric shock risks. Arc flash hazards develop when equipment electrical faults occur during initial energisation due to transportation damage, incorrect voltage supply, or manufacturing defects. Electrical safety during equipment installation requires clear communication between mechanical installers and electrical contractors, implementation of isolation verification before work on electrical components, and staged commissioning procedures preventing premature energisation. Falls from height during equipment installation occur when accessing rooftop equipment locations, working from ladders or platforms during elevated equipment mounting, and installing equipment on mezzanines or elevated platforms. Rooftop access for equipment installation may utilise temporary ladders, building maintenance units, or scaffolding depending on equipment weight and installation duration. Equipment positioning on rooftops requires edge protection preventing falls, as workers focused on equipment alignment may not maintain fall hazard awareness. Ladder work installing wall-mounted equipment creates overreaching hazards as workers attempt to complete installations without ladder repositioning. Mobile elevated work platforms used for equipment access require outrigger deployment on stable ground, proper platform loading considering equipment component weight and worker occupancy, and platform tie-off if equipment installation creates lateral forces on platform. Complex installations requiring extended work at height should transition from ladders to scaffolding or fixed platforms providing safer work positions. Commissioning hazards emerge when transitioning from installation to operational testing as equipment contains stored energy from electrical supplies, pressurised fluids, rotating components, and elevated temperatures. Commissioning procedures must implement staged energisation confirming safe operation at each stage before proceeding, rather than full energisation followed by troubleshooting when faults are detected. Mechanical equipment with rotating components requires verification that guards are installed, drive coupling alignment prevents vibration, and mechanical interlocks prevent access during operation. Pressurised systems require staged pressurisation with leak checking at each pressure increment, rather than immediate full pressure risking catastrophic failure if installation faults exist. Thermal systems including ovens, boilers, and process equipment develop high temperatures during commissioning requiring burn hazard protection and verification that thermal expansion does not create structural stresses. Emergency shutdown systems must be tested verifying operation before commissioning proceeds, providing workers ability to rapidly de-energise equipment if hazardous conditions develop.

Risk register

Manual Handling Injuries from Heavy Equipment Components

High

Equipment installation involves substantial manual handling of components weighing from 20 kilograms for smaller items to over 100 kilograms for major components including motors, pumps, equipment frames, and panels. Workers lift components from delivery packaging, carry items to installation locations, position equipment precisely for mounting, and work in awkward postures during assembly operations. Commercial kitchen equipment including ovens, refrigerators, and preparation tables weighs 100-300 kilograms requiring multi-person teams or mechanical aids for positioning. Industrial machinery components including motor assemblies, gearboxes, and structural frames possess awkward geometries making grip and control difficult. Overhead installation work mounting equipment on walls or elevated positions requires sustained overhead arm positions causing shoulder fatigue and strain. Repetitive assembly operations assembling multi-component equipment creates cumulative shoulder, back, and wrist trauma even when individual lifts are within limits. Confined workspace conditions around installed equipment require workers to reach, twist, and bend to access mounting points and connections.

Consequence: Chronic lower back pain and disc injuries requiring extended medical treatment, shoulder rotator cuff tears and strains requiring surgical intervention, acute back strains from sudden overload during positioning operations, wrist and hand injuries from gripping heavy awkward components, hernia development from excessive lifting without assistance, and long-term musculoskeletal disorders reducing capacity to continue installation work.

Crush and Pinch Injuries During Equipment Positioning and Assembly

High

Heavy equipment creates crush hazards during positioning operations, assembly processes, and when supported on temporary blocking or supports. Equipment weighing hundreds of kilograms to multiple tonnes shifted using jacks, skates, rollers, or forklifts may move unexpectedly if ground conditions uneven, centre of gravity misjudged, or movement control inadequate. Workers' hands and feet are trapped between equipment and foundations, walls, or other equipment during final positioning as millimetre adjustments are attempted. Pinch points develop between equipment components during assembly as panels are aligned, covers installed, and components fitted together. Equipment supported on temporary timber blocking or steel supports tips if blocking configuration unstable, load distribution uneven, or equipment is bumped during subsequent work. Partially assembled equipment lacks structural rigidity creating collapse hazards if workers lean against incomplete assemblies or use unfinished structures for support. Overhead equipment including wall-mounted units may fall if temporary support inadequate during mounting fastener installation.

Consequence: Severe crush injuries to hands, feet, and limbs requiring amputation in extreme cases, fractures and soft tissue damage from equipment impacts, fatal crushing if workers trapped beneath falling equipment, finger amputations from pinch points between components, and traumatic injuries from equipment collapse during assembly.

Electrical Shock and Arc Flash During Connection and Commissioning

High

Electrical hazards emerge during equipment electrical connection work and commissioning testing as equipment is energised and tested for operational performance. Electrical connection work may be performed by mechanical installers for plug-and-lead connections or require licensed electricians for hardwired installations depending on electrical characteristics and regulatory requirements. Energising equipment before mechanical assembly complete creates unexpected movement hazards when motors start or actuators operate. Working on energised equipment during commissioning troubleshooting creates shock hazards if workers contact active conductors or terminal connections. Arc flash events occur when electrical faults develop during initial energisation from transportation damage, incorrect voltage supply, or manufacturing defects creating arc blast and burn hazards. Equipment with multiple power supplies including control circuits and main power creates shock hazards if isolation verification incomplete. Internal equipment wiring may be energised from unexpected sources including UPS systems, battery backup, or capacitor stored charge remaining after primary supply isolation.

Consequence: Fatal electrocution from contact with live conductors during connection or commissioning work, severe electrical burns requiring extensive skin grafting and rehabilitation, arc flash burns causing permanent scarring and vision loss, cardiac arrest from electric shock requiring emergency medical intervention, and equipment damage from electrical faults requiring expensive repair or replacement.

Falls from Height During Elevated Equipment Installation

High

Installation of elevated equipment including rooftop air conditioning units, wall-mounted equipment, and equipment on mezzanines and elevated platforms creates fall hazards. Rooftop access using ladders, scaffolding, or building maintenance units exposes workers to fall risks during ascent, whilst working on roofs. Equipment positioning on rooftops near roof edges creates fall hazards as workers focused on alignment may not maintain edge protection awareness. Ladder work installing wall-mounted equipment encourages overreaching to complete installations without ladder repositioning creating tip-over and fall hazards. Mobile elevated work platforms used for equipment installation require stable ground conditions, proper outrigger deployment, and platform loading within rated capacity. Scaffolding erected for equipment installation must provide adequate working platforms with guardrails, accommodate equipment component weights and worker occupancy, and maintain stability during equipment positioning activities. Penetrations through flooring for equipment connections create fall hazards if not properly protected during installation work.

Consequence: Fatal injuries from falls onto concrete floors or ground surfaces, spinal injuries causing permanent paralysis, traumatic brain injuries from head impact during falls, multiple fractures requiring extended hospitalisation, and soft tissue injuries from falls at lower heights causing chronic pain conditions.

Equipment Instability and Tipping During Installation and Commissioning

Medium

Equipment possesses tipping hazards during installation before permanent mounting is completed, particularly tall narrow equipment with high centres of gravity. Free-standing equipment including refrigerators, storage racks, and tall machines tips if bumped, if floor surface uneven causing lean, or during connection activities creating lateral forces. Equipment mounted on wheels or casters rolls unexpectedly if parking brakes not engaged or floor slope allows movement. Seismic restraints required in many jurisdictions for safety-critical equipment remain uninstalled until final commissioning, leaving equipment vulnerable to movement. Equipment positioned for installation but awaiting final securing creates tip hazards for extended periods if work interruptions occur. Commissioning testing may generate vibration or dynamic forces causing equipment movement if not adequately secured. Access panels and covers removed during commissioning shift equipment centre of gravity creating previously stable equipment becoming unstable.

Consequence: Workers struck by tipping equipment causing crush injuries, equipment damage requiring expensive repair or replacement before commissioning, project delays whilst damaged equipment is repaired or replaced, secondary injuries from workers attempting to prevent equipment falling, and damage to surrounding building finishes and adjacent equipment.

Rotating Machinery and Moving Parts During Testing and Commissioning

Medium

Commissioning operations energise equipment creating moving parts hazards from rotating shafts, belt drives, fan blades, and conveyor systems. Equipment guards may not be installed during initial commissioning to allow observation of mechanical operation and alignment verification. Workers conducting commissioning tests may not recognise mechanical hazards if unfamiliar with equipment operation and expected movement when energised. Unexpected equipment startup occurs when electrical interlocks bypassed for testing, remote start signals activate equipment without warning, or automatic control systems initiate operation. Clothing, hair, gloves, and tools are caught in rotating components causing entanglement and dragging workers into machinery. Drive coupling misalignment creates vibration during initial operation requiring shutdown and adjustment, potentially whilst components still rotating. Variable speed equipment may accelerate rapidly during testing exceeding expected movement speeds. Pneumatic and hydraulic actuators operate under stored pressure creating rapid unexpected movement even after primary power isolated.

Consequence: Severe injuries from entanglement in rotating machinery including traumatic amputations, lacerations from contact with moving belts and chains, fractures and soft tissue damage from impacts with moving components, scalping injuries from hair entanglement, and fatal injuries from workers dragged into machinery.

Pressurised Fluid and Gas Systems During Connection and Testing

Medium

Equipment installations involving pressurised fluids including water, hydraulic oil, compressed air, refrigerants, and process gases create pressure-related hazards during connection and commissioning. Connection work on pressurised systems requires verification of isolation preventing fluid or gas release during fitting disconnection and installation. Pressure testing of newly installed connections and piping reveals leaks through fluid spray, gas release, or catastrophic fitting failure if installation defects exist. Hydraulic systems operating at pressures exceeding 10,000 kPa create injection injury hazards where high-pressure fluid penetrates skin causing serious internal injuries. Refrigerant releases create asphyxiation hazards in confined equipment rooms through oxygen displacement and create chemical exposure from refrigerant contact. Compressed air connections failing during pressurisation create projectile hazards from flying fittings and whipping hoses. Steam systems contain thermal energy and pressure creating severe burn hazards if connections fail during commissioning.

Consequence: High-pressure fluid injection injuries requiring emergency surgery and amputation to prevent tissue death, severe burns from steam and hot fluid releases, asphyxiation from refrigerant or inert gas releases in confined spaces, impact injuries from projectile fittings and whipping hoses, chemical burns from process fluid contact, and equipment damage from pressurisation failures.

Confined Space Entry During Equipment Installation in Plant Rooms

Medium

Equipment installation in basement plant rooms, mechanical spaces, and underground facilities may require confined space entry procedures when spaces possess restricted entry/exit, limited ventilation, or potential atmospheric hazards. Plant rooms during construction may lack permanent ventilation systems creating oxygen-depleted or contaminated atmospheres. Welding, cutting, painting, and adhesive work during installation generates fumes and oxygen depletion in poorly ventilated spaces. Equipment positioned in confined spaces limits egress routes preventing rapid evacuation if emergencies occur. Refrigerant leaks from equipment commissioning create asphyxiation hazards through oxygen displacement. Carbon dioxide from concrete curing and decomposing materials accumulates in unventilated basements. Large equipment installation in confined spaces creates rescue difficulties if workers become injured or trapped. Extended work periods in hot, humid plant rooms creates heat stress and fatigue affecting worker judgment and physical capability.

Consequence: Asphyxiation from oxygen-depleted or contaminated atmospheres in confined plant rooms, toxic gas exposure from refrigerant leaks or chemical releases, heat stroke and exhaustion from work in hot confined spaces, crush injuries from confined workspace creating proximity to moving equipment, and rescue difficulties if workers become incapacitated in restricted access locations.

Electrical Isolation Verification and Licensed Electrician Requirements

Elimination

Eliminate electrical shock hazards through isolation verification before work on equipment electrical systems and engagement of licensed electricians for hardwired electrical connection work. Establish clear demarcation between mechanical installation work and electrical work requiring licensing. Implement isolation verification procedures including physical disconnection, lockout-tagout systems, and voltage testing before work on electrical components. Verify equipment possesses all necessary electrical safety features including earth connections, residual current protection, and emergency isolation switches. Prohibit energisation of equipment until mechanical installation completed, guards installed, and electrical verification confirmed. Implement staged commissioning procedures energising equipment progressively with safety checks at each stage rather than full energisation followed by troubleshooting.

Implementation

1. Engage licensed electricians for all hardwired electrical connection work including equipment supply connections and control circuit wiring 2. Verify electrician licences current and class appropriate for voltage and current characteristics of equipment being connected 3. Establish work demarcation clarifying which electrical activities are within mechanical installer scope - typically plug-and-socket connections only 4.

Position workers away from electrical equipment during initial energisation protecting from potential arc flash events from electrical faults 12. Conduct thermal imaging of electrical connections 24 hours after commissioning identifying hot connections requiring remedial work

Height Access Equipment and Fall Protection Systems

Engineering Control

Provide safe height access for elevated equipment installation through selection of appropriate access equipment including scaffolding, elevated work platforms, ladders, or permanent access systems. Prioritise collective fall protection including work platforms with guardrails over personal fall arrest systems. For extended work at height, establish scaffolding providing stable work platforms with material handling capability. Utilise mobile elevated work platforms for shorter-duration work requiring repositioning flexibility. Implement fall arrest systems including harnesses and anchorages for work where collective protection not feasible. Establish edge protection at roof level during rooftop equipment installation.

Staged Commissioning and Energy Isolation Procedures

Administrative Control

Implement staged commissioning procedures energising equipment progressively with safety verification at each stage preventing hazardous conditions during initial operation. Establish commissioning sequence starting with auxiliary systems, progressing to control circuits, and finally applying main power. Verify mechanical assembly completed, guards installed, and clearances adequate before any energisation. Test emergency shutdown systems confirming operation before commissioning proceeds. Implement energy isolation for mechanical systems including compressed air, hydraulic power, and steam supplies allowing safe troubleshooting if faults detected. Monitor equipment behaviour during initial operation identifying abnormal sounds, vibrations, temperatures, or movements requiring immediate shutdown and investigation. Establish commissioning exclusion zones preventing unauthorised personnel access to equipment during energisation and testing.

Implementation

1. Develop commissioning procedure documenting staged energisation sequence and verification checks required at each stage 2. Verify mechanical installation completed including all guards, covers, and access panels properly installed before any energisation 3. Check clearances to adjacent equipment and building elements ensuring adequate spacing for safe operation and maintenance access 4.

Plan installation sequence coordinating with other trades including electrical contractors, plumbers, and HVAC contractors for concurrent utility connection work. Obtain building permits and inspections required for equipment installation including electrical, plumbing, and building permits. Engage manufacturer representatives for technical support if complex installation requires specialist knowledge.

Safety considerations

Verify floor loading capacity adequate for equipment weight plus installation equipment including forklifts if used for positioning. Identify overhead clearance requirements for equipment delivery and installation ensuring adequate height for lifting and positioning. Assess access route from delivery location to final installation point identifying obstacles requiring removal or route modifications. Consider building occupancy during installation planning operations around occupied areas or scheduling work outside business hours.

2

Foundation and Mounting Preparation Verification

Verify foundation and mounting preparation completed according to manufacturer specifications before equipment delivery. Inspect concrete foundations checking dimensions match specifications within tolerance limits, anchor bolts positioned correctly with vertical alignment and projection heights per drawings, concrete cured adequately before loading typically minimum 7 days for normal curing, and surface flatness within manufacturer tolerance using precision level. For structural steel mounting frames, verify frame dimensions and level correct, bolt holes align with equipment mounting patterns, welded connections completed per structural drawings, and frame adequately secured to building structure supporting static and dynamic equipment loads. For floor-mounted equipment, verify floor construction adequate for equipment loads checking slab thickness, reinforcement, and underlying soil or structural support. Inspect floor surface flatness and cleanliness ensuring surface suitable for equipment installation. For wall-mounted equipment, verify wall construction adequate for mounting loads identifying structural framing or providing reinforcement if wall alone insufficient. Document foundation verification photographing critical dimensions and conditions demonstrating compliance before equipment delivery.

Safety considerations

Verify anchor bolt embedment depths adequate per structural design preventing bolt pullout under equipment loads. Check anchor bolt threads protected during concrete placement preventing thread damage and allowing nut installation. Confirm floor loading assessment completed by structural engineer if equipment weight substantial or floor construction uncertain. Identify underground services beneath floor slab before drilling anchors preventing damage to electrical, plumbing, or data services.

Equipment Delivery, Receipt, and Damage Inspection

Coordinate equipment delivery scheduling adequate personnel and mechanical equipment for receipt and positioning. Prepare delivery access route removing obstacles, protecting floor finishes, and establishing clear path from delivery vehicle to installation location. Position forklift or other mechanical handling equipment ready for equipment unloading. Receive equipment delivery checking shipping documents against purchase orders verifying correct equipment supplied. Inspect shipping containers and equipment for transportation damage before signing delivery acceptance - document any damage observed with photographs and written descriptions. Unpack equipment systematically organising components by assembly sequence and checking packing lists confirming all components present. Inspect equipment thoroughly for concealed damage not visible in packaging including dents, cracks, loose fasteners, damaged controls, and missing accessories. Separate damaged components isolating from installation work and notifying supplier immediately about damage for replacement or repair. Store equipment components in secure dry location protected from weather and site activities until installation commences. Maintain manufacturer documentation with equipment ensuring manuals accessible throughout installation process.

Safety considerations

Verify forklift capacity adequate for equipment weights - review shipping documentation for component weights before attempting to lift. Check delivery route floor capacity for loaded forklift weights where equipment must be transported through buildings. Inspect packaging for hazard warnings about pressurised components, hazardous substances, or special handling requirements. Secure stored equipment preventing tipping or movement if bumped during site activities - install temporary bracing or blocking for tall unstable items.

4

Equipment Transport and Positioning

Transport equipment from delivery location to final installation position using appropriate mechanical equipment and manual handling techniques. For heavy equipment, utilise forklift positioning forks beneath equipment centre of gravity and lifting gradually verifying load stability before movement. Transport through buildings slowly maintaining awareness of doorway widths, ceiling heights, floor loading, and obstacles requiring navigation. For equipment moved using pallet jacks or dollies, ensure casters or wheels locked during loading preventing rolling, distribute weight evenly on moving equipment platform, and control movement speed using multiple personnel for large items. Position equipment on installation location using precision positioning techniques including measuring from reference points, using laser alignment tools for critical positioning, and implementing incremental adjustments using pry bars or jacks for fine positioning. Install temporary support blocking or equipment levelling feet before releasing lifting equipment ensuring stable support during subsequent assembly and connection work. Verify equipment level in all directions using precision spirit levels adjusting support blocking or levelling feet achieving specified tolerance. Protect equipment during positioning using padding or protective sheets preventing damage to finished surfaces.

Safety considerations

Establish exclusion zones around equipment movement paths preventing personnel in potential tip-over or collision zones. Verify floor capacity adequate along entire transport route not just final installation location - avoid overloading floors during transport. Position workers away from equipment pinch points during final positioning - use mechanical jacks or pry bars for adjustments rather than hands and feet. Ensure temporary support blocking stable and adequate for equipment weight before releasing crane or forklift preventing equipment settling or tipping.

5

Equipment Assembly and Component Installation

Assemble equipment following manufacturer sequence ensuring structural integrity maintained throughout progressive assembly. Review assembly drawings identifying component installation order, fastener specifications, and alignment requirements. Position first components ensuring correct orientation and alignment before fastening. Install structural fasteners hand-tight initially allowing alignment adjustment before final tightening to specified torque values. Use calibrated torque wrenches for critical fasteners including anchor bolts and structural connections applying manufacturer-specified torque values. Install components progressively checking alignment at each stage correcting misalignment before proceeding to avoid cumulative errors. Position gaskets, seals, and alignment dowels per specifications ensuring proper installation before component assembly. Install mechanical components including motors, gearboxes, pumps, and drive systems verifying correct alignment and preventing binding or interference. Connect internal piping and wiring following manufacturer routing and securing requirements. Install covers, panels, and access doors ensuring proper fitting and fastener installation. Conduct assembly inspection verifying correct component installation, fastener tightness, and clearances before proceeding to utility connections.

Safety considerations

Support partially assembled equipment with temporary bracing preventing collapse if structure lacks rigidity until assembly completed. Avoid working beneath suspended or cantilevered components until adequately secured and supported. Use manual handling aids for component positioning preventing injuries from awkward lifting and holding during fastener installation. Verify component orientation correct before fastening - removing incorrectly installed components creates additional manual handling and may damage components.

6

Utility Connection and Electrical Installation

Connect equipment utilities including electrical supply, water, gas, compressed air, and data communications following manufacturer specifications and relevant codes. Coordinate electrical connection work with licensed electricians clearly delineating responsibilities between mechanical installers and electrical contractors. For electrical connections, verify supply voltage and phase characteristics match equipment requirements, install appropriate circuit protection including circuit breakers and residual current devices, implement equipment earthing per AS/NZS 3000 requirements, and test installation before energisation. Connect water supply ensuring adequate pressure and flow for equipment requirements, install isolation valves allowing equipment service without system shutdown, implement backflow prevention if equipment could contaminate water supply, and pressure test connections before commissioning. For gas connections, engage licensed gasfitters for installation, conduct leak testing before commissioning using approved methods, install emergency isolation valves in accessible locations, and verify ventilation adequate for gas equipment operation. Connect compressed air systems implementing pressure regulation, moisture removal, and appropriate fittings compatible with equipment ports. Install data and control connections using appropriate cable types and implementing cable management preventing damage.

Safety considerations

Verify electrical supply isolated using lockout-tagout before commencing connection work preventing inadvertent energisation. Test for voltage presence using appropriate voltage detector before touching electrical components. Engage appropriately licensed contractors for electrical, gas, and plumbing work ensuring compliance with regulatory requirements. Pressure test all fluid and gas connections at operating pressure before commissioning verifying leak-free installation and preventing operational failures.

7

Pre-Commissioning Safety Verification and Guarding Installation

Conduct comprehensive pre-commissioning safety inspection before equipment energisation. Verify mechanical assembly completed including all fasteners tightened to specification, components correctly aligned, and no loose or missing parts. Install all safety guards, covers, and access panels ensuring rotating components, pinch points, and electrical parts properly protected. Check emergency shutdown systems including e-stop buttons and emergency isolation switches verifying accessibility and mechanical operation. Verify clearances to adjacent equipment and building elements ensuring adequate spacing for safe operation and maintenance access. Inspect utility connections confirming proper installation and absence of leaks. Check equipment earthing and bonding verifying electrical safety. Verify fire protection including extinguisher accessibility and sprinkler clearances maintained. Establish commissioning exclusion zones preventing unauthorised personnel access during energisation and testing. Brief all personnel about commissioning activities, energy sources present, emergency shutdown procedures, and hazards during testing. Document safety verification inspection recording all checks completed and deficiencies corrected before proceeding to energisation.

Safety considerations

Prohibit equipment energisation until all guards and safety devices installed preventing access to hazardous moving parts and electrical components. Test emergency shutdown systems mechanically before electrical energisation verifying immediate equipment isolation when activated. Position personnel away from equipment during initial energisation protecting from potential equipment malfunction or unexpected movement. Ensure adequate fire protection readily accessible during commissioning when electrical and mechanical faults most likely to occur.

8

Staged Commissioning and Performance Testing

Conduct staged equipment commissioning progressively energising systems with safety verification at each stage. Commence with control circuit energisation verifying control system operation, display functions, and sensor readings before applying main power. Energise auxiliary systems including cooling, lubrication, and monitoring systems verifying operation before loading main equipment. Apply main power incrementally starting at minimum load or reduced capacity whilst monitoring equipment behaviour. Observe equipment operation continuously during commissioning watching for abnormal sounds indicating bearing problems or component interference, excessive vibration suggesting misalignment or imbalance, unusual smells indicating electrical overheating or mechanical friction, and unexpected movements from loose components or incorrect control settings. Conduct functional testing verifying equipment performs all required operations including starting, stopping, load variation, and emergency shutdown. Measure operational parameters including temperatures, pressures, flows, electrical current, and rotational speeds verifying values within manufacturer specifications. Adjust equipment settings optimising performance whilst maintaining safety limits. Document commissioning activities recording test results, adjustments made, and verification of operational parameters. Identify any deficiencies requiring correction before operational handover.

Safety considerations

Monitor equipment continuously during initial energisation ready to implement emergency shutdown if hazardous conditions develop. Limit personnel in commissioning area to essential personnel reducing exposure if equipment malfunctions. Verify energy isolation procedures effective allowing rapid shutdown of all energy sources if required. Document all adjustments and settings for maintenance reference and troubleshooting if operational problems develop after handover.

Frequently asked questions

What manual handling weight limits should be applied during equipment installation work?

Manual handling weight limits during equipment installation should follow WHS regulatory guidance and consider individual worker capability, task characteristics, and workplace conditions. Safe Work Australia provides guidance that loads exceeding 55kg should not be manually lifted by a single person regardless of circumstances, whilst loads exceeding 23kg require risk assessment considering frequency, posture requirements, and worker training. For equipment installation specifically, conservative limits recognise that many components are awkward shapes with difficult grip points, requiring work in confined spaces or awkward postures, and involving repetitive lifting during assembly operations. Practical limits typically restrict single-person lifting to 15-20kg for frequent lifts or awkward components, require two-person team lifting for components 20-40kg, and mandate mechanical lifting aids for components exceeding 40kg or involving overhead positioning. These limits may be further reduced when installing equipment in confined spaces, when working from ladders or elevated platforms where balance is compromised, or when environmental conditions including heat or cold affect worker capacity. Individual worker assessment should consider physical capability, experience with manual handling, any previous injuries affecting lifting capacity, and worker preference about their comfortable lifting limits. Mechanical lifting aids should be provided proactively rather than expecting workers to request assistance, as workplace culture sometimes discourages workers from acknowledging they need help with manual handling. For complex installations involving multiple heavy components, pre-work planning should identify all lifting requirements and ensure appropriate mechanical equipment available from project commencement preventing reliance on manual handling due to inadequate equipment provision.

What foundation inspection and preparation is required before equipment installation?

Foundation inspection before equipment installation must verify dimensional accuracy, structural adequacy, and surface preparation meeting manufacturer specifications. Concrete foundations require inspection of overall dimensions using measuring tape or laser distance meters confirming length, width, and height match specification drawings within tolerance limits typically ±10mm. Anchor bolt positions must be verified using templates or precise measurements confirming bolt spacing and offset from foundation edges match equipment mounting hole patterns within ±5mm tolerance for critical alignments. Anchor bolt projection above foundation surface requires verification ensuring adequate thread engagement for nuts whilst not exceeding equipment base clearance. Verify anchor bolt vertical alignment using plumb bob or laser level confirming bolts perpendicular to foundation surface within 3 degrees tolerance. Inspect concrete curing adequacy requiring minimum 7 days curing for normal conditions or 28 days for full strength before loading for heavy equipment. Check surface flatness using precision spirit level and straight edge verifying deviation within manufacturer tolerance commonly 3mm over 3 metre length. For structural steel mounting frames, verify frame level and alignment correct, weld quality acceptable with no cracks or incomplete penetration, and frame securely anchored to building structure capable of resisting equipment static loads plus dynamic forces from vibration. Floor-mounted equipment requires floor loading assessment by structural engineer if slab construction uncertain or equipment weight substantial, particularly for suspended concrete slabs in multi-storey buildings. Document foundation inspection with photographs and measurements demonstrating compliance providing evidence for manufacturer warranty validation and regulatory inspection if required. Identify and correct deficiencies before equipment delivery preventing installation delays and avoiding equipment damage from incorrect foundation preparation.

What electrical work can be performed by equipment installers versus requiring licensed electricians?

The demarcation between equipment installer electrical work and work requiring licensed electricians depends on electrical characteristics, connection method, and state electrical safety regulations. Generally, mechanical installers can perform plug-and-socket connections using standard power points and plugs without electrical licensing, provided no modification of electrical installation or equipment supply cords occurs. Equipment supplied with factory-fitted plugs can be connected to appropriate socket outlets by installers after verifying socket voltage and current rating match equipment requirements. Installation of equipment requiring hardwired connections including direct connection to switchboards, junction boxes, or fixed wiring systems must be performed by licensed electricians holding appropriate electrical worker licences for voltage and installation type. Control circuit wiring, motor connections, and integration with building management systems typically require electrical licensing. Some jurisdictions permit restricted electrical work by mechanical trades under supervision of licensed electricians for specific connection types, though this varies by state regulations. Equipment installers must verify electrical supply characteristics match equipment requirements including voltage, phase, frequency, and current capacity, though actual connection work if hardwired requires electrician. Testing of electrical systems including insulation resistance testing, earth continuity verification, and RCD testing requires electrical licensing or must be conducted by licensed electricians. When uncertainty exists about work boundaries, engage licensed electricians rather than assuming work is within mechanical trade scope, as performing electrical work without appropriate licensing creates regulatory violations, safety hazards, and may void equipment warranties. Clear communication between mechanical installers and electrical contractors during project planning clarifies responsibilities, ensures adequate electrical contractor scheduling, and prevents delays from discovering electrical work requirements during installation.

What commissioning safety procedures should be followed when energising equipment for the first time?

First-time equipment energisation requires staged commissioning procedures progressively applying energy sources with safety verification at each stage. Commence with comprehensive pre-energisation inspection verifying mechanical assembly completed including all fasteners tightened to specification, safety guards and covers properly installed, utility connections completed and leak-tested, and clearances to surrounding equipment adequate for safe operation. Test emergency shutdown systems mechanically confirming e-stop buttons and emergency isolation switches operate correctly before energisation providing immediate shutdown capability. Brief all personnel about commissioning activities, energy sources that will be applied, emergency shutdown procedures, and their roles during testing. Establish commissioning exclusion zones preventing unauthorised personnel access within 3 metres of equipment during energisation. Begin staged energisation with control circuit power application verifying control system operates correctly, displays function properly, and monitoring systems provide expected readings. Energise auxiliary systems including cooling, lubrication, and safety interlocks verifying operation before main power application. Apply main power at minimum capacity or reduced load monitoring equipment behaviour for abnormal sounds, excessive vibration, unusual smells indicating overheating, or unexpected movements suggesting mechanical problems. Incrementally increase load whilst continuously monitoring temperatures, pressures, flows, and electrical parameters verifying values remain within specification limits. Immediately shutdown equipment if any abnormal conditions observed including unexpected movements, excessive noise or vibration, rapid temperature rise, or safety system alarms, investigating cause before recommencing testing. Document all commissioning activities including test sequence, parameter measurements, adjustments made, and verification of performance requirements. Position personnel away from equipment during initial energisation protecting from potential equipment malfunction including unexpected rotation, fluid leaks under pressure, or electrical faults. This staged approach allows early detection of installation errors or equipment damage preventing catastrophic failures from full energisation before problems are identified.

What seismic restraint requirements apply to equipment installation in different Australian locations?

Seismic restraint requirements for equipment installation vary across Australian locations based on earthquake hazard levels defined in AS 1170.4 Earthquake Actions. Australian earthquake hazard map divides country into zones from very low to moderate seismic hazard, with higher hazard areas including Adelaide, parts of Victoria, and some western Australian regions requiring more stringent seismic provisions than lower hazard eastern coastal areas. Building Code of Australia references AS 1170.4 requiring seismic restraint design for building components including mechanical and electrical equipment depending on importance level, component weight and height, building height, and earthquake hazard zone. Part E1.10 of BCA requires building elements and components capable of resisting earthquake forces, though specific equipment restraint requirements often depend on certifying authority interpretation and project specifications. Essential services equipment including emergency generators, fire pumps, medical equipment in hospitals, and emergency communication systems typically require seismic restraint regardless of location due to importance level classification requiring post-earthquake functionality. Heavy equipment including large HVAC units, industrial machinery, and water tanks may require seismic restraint in moderate hazard zones if equipment weight, height, or mounting configuration creates significant overturning potential. Seismic restraint design typically involves structural engineering assessment calculating earthquake forces on equipment based on component weight, centre of gravity height, and building acceleration response. Restraint methods include increased anchor bolt capacity to resist overturning moments, installation of lateral restraint brackets or cables preventing sliding and rotation, vibration isolation system integration with seismic stops limiting horizontal displacement, and equipment base strengthening distributing forces to mounting structures. Equipment manufacturers may provide seismic certification demonstrating equipment can resist specified earthquake forces when installed per manufacturer requirements. Documentation requirements include structural calculations demonstrating restraint adequacy, installation details showing restraint configuration, and certification that installation complies with design requirements. Equipment installers should verify project specifications and local building certifier requirements early in planning, as retrofitting seismic restraints after installation is substantially more difficult and expensive than incorporating restraints during initial installation.

What should be included in equipment installation documentation and handover records?

Comprehensive equipment installation documentation provides evidence of correct installation, supports warranty claims, facilitates future maintenance, and demonstrates regulatory compliance. Documentation should include manufacturer equipment data including model numbers, serial numbers, and manufacturing dates allowing identification for future parts ordering and warranty verification. Installation specifications and drawings showing equipment location, foundation details, utility connection routing, and seismic restraint configuration if applicable provide as-built reference for future modifications. Foundation inspection records including photographs of anchor bolt installation, dimension verification measurements, and concrete test results if strength testing conducted demonstrate foundation adequacy. Equipment assembly documentation including torque wrench calibration certificates, photographic records of progressive assembly stages, and verification of critical fastener installation confirms correct assembly. Utility connection records including electrical installation certificates from licensed electricians, pressure test reports for fluid connections, and leak test results for gas systems verify connection integrity. Commissioning test results recording operational parameters including temperatures, pressures, flows, electrical characteristics, and performance measurements against manufacturer specifications demonstrate equipment achieves design performance. Adjustment and setting documentation recording control system configurations, setpoints, and optimisation parameters supports future troubleshooting and maintenance. Manufacturer warranty documentation including warranty registration, warranty terms and conditions, and any extended warranty purchases protects building owner investment. Maintenance requirements including recommended maintenance schedules, spare parts lists, and service contact information facilitates ongoing equipment reliability. Training records if operator training provided during commissioning documents personnel qualification for equipment operation. Safety documentation including identified hazards, required PPE, emergency procedures, and isolation procedures protects future maintenance personnel. Organise documentation in equipment operation and maintenance manuals provided to building owner during project handover, with digital copies maintained by installation contractor for future reference and warranty support. Complete documentation demonstrates professional installation quality, facilitates building certification processes, and provides essential information supporting equipment lifecycle management.
