| Layout and Site Preparation |
Soil, aggregate, temporary access routes, and setting-out points |
Occasional to daily use; accuracy typically within 5–10 mm for general building layout |
Surveying toolsSite-preparation tools |
Laser level or optical level; measuring range suited to site size; compact plate compactor for small areas |
Positioning foundations, checking elevations, compacting walkways and service trenches |
Verify calibration, line-of-sight conditions, ground bearing capacity, and underground utilities before excavation |
| Concrete Drilling and Anchoring |
Concrete, reinforced concrete, masonry, and blockwork |
Light: up to 20 holes/day; medium: 20–80 holes/day; heavy: more than 80 holes/day |
Rotary hammerDiamond drilling |
SDS-type rotary hammer for impact drilling; diamond core equipment when low vibration, larger diameters, or precise openings are required |
Mechanical anchors, electrical penetrations, plumbing sleeves, and structural openings |
Use dust extraction or wet drilling where appropriate; scan for reinforcement and services; control silica exposure and noise |
| Cutting and Shaping |
Timber, sheet goods, metal sections, tile, brick, and concrete products |
Intermittent cuts for repair work or repeated cuts for production installation |
Portable cutting toolsStationary saws |
Blade or wheel matched to material; adjustable cutting depth; adequate guarding; dust or spark control |
Framing, pipe fitting, tile installation, metal fabrication, and masonry trimming |
Confirm material compatibility, secure the workpiece, use eye and hearing protection, and maintain guards |
| Fastening and Assembly |
Timber, light-gauge steel, drywall, cladding, and mechanical connections |
Low volume: manual fastening; medium volume: several hundred fasteners/day; high volume: repetitive production work |
Impact driversDrillsTorque tools |
Adjustable clutch or torque control; compatible drive system; battery capacity or pneumatic supply matched to shift length |
Framing, cabinetry, drywall fixing, façade installation, and equipment assembly |
Use specified torque for structural or mechanical fasteners; reduce repetitive strain through balanced tools and task rotation |
| Surface Preparation |
Concrete floors, coatings, plaster, timber, and painted surfaces |
Small repair areas below 50 m²; medium areas of 50–500 m²; large areas above 500 m² |
GrindersSandersScarifiers |
Disc or abrasive selected for substrate; variable speed where heat or finish quality matters; integrated extraction preferred |
Removing laitance, paint, adhesive residue, corrosion, and uneven surface material |
Control airborne dust, check floor moisture and hardness, and protect adjacent finished surfaces |
| Earthmoving and Excavation |
Soil, clay, gravel, fill, and mixed ground conditions |
Small trenches or landscaping: under 100 m³; medium excavation: 100–1,000 m³; large excavation: above 1,000 m³ |
Mini excavatorExcavatorLoader |
Operating weight, bucket capacity, digging depth, tail-swing requirement, transport limits, and ground pressure |
Foundations, drainage trenches, utility installation, grading, and material loading |
Plan exclusion zones, inspect slopes, identify buried services, and select attachments for the actual soil condition |
| Lifting and Material Handling |
Blocks, steel sections, panels, equipment, pallets, and prefabricated components |
Lift frequency, maximum load, reach, height, and required placement accuracy |
HoistsForkliftsTelehandlers |
Rated capacity must exceed the planned load at the required reach; consider load centre, headroom, and attachment type |
Moving materials around sites, placing roof components, installing equipment, and loading work platforms |
Use certified lifting accessories, observe load charts, control pedestrian access, and inspect equipment before use |
| Compaction and Concrete Placement |
Granular fill, soil, fresh concrete, slabs, and footings |
Area, layer thickness, concrete volume, access conditions, and required finish quality |
CompactorsConcrete vibratorsPower trowels |
Compaction force matched to soil type; vibrator head sized to reinforcement spacing; finishing equipment selected for slab area |
Road bases, trench backfill, foundations, floor slabs, and concrete paving |
Follow specified lift thickness and curing requirements; avoid over-vibration and maintain safe separation from moving equipment |
| Access, Height, and Finishing |
Walls, ceilings, façades, roofs, and elevated services |
Working height, duration, number of workers, and frequency of relocation |
ScaffoldingLiftsMobile access equipment |
Platform height and capacity; ground suitability; reach; obstacle clearance; fall-protection compatibility |
Painting, façade repair, ceiling installation, electrical work, and mechanical services |
Use inspected access systems, maintain guardrails, control dropped-object risks, and respect wind limitations outdoors |
| Demolition and Deconstruction |
Concrete, masonry, steel, timber, partitions, and building finishes |
Selective removal of small areas or continuous removal of structural and non-structural elements |
BreakersReciprocating toolsDemolition excavators |
Impact energy, tool weight, vibration level, attachment compatibility, and debris-handling capacity |
Removing slabs, partitions, tiles, pipework, and isolated structural components |
Complete a survey before work, isolate services, establish exclusion zones, and manage dust, noise, vibration, and waste |
