1. STRUCTURAL RENOVATION & OPENINGS
Creating door or window openings in load-bearing masonry or poured concrete requires vibration control to prevent fracturing lintel seats or compromising structural bond lines.
- Recommended Set: High-torque diamond wall saw (350 mm blade) with twin guide rails, 110V 3.3 kVA continuous transformer, slurry wet vac with submersible pump, and 11 kg medium breaker with spade chisel for stitch breakout.
- Operational Note: Propping with certified adjustable steel props must precede any structural cut. Never dry-cut reinforced brickwork without sealed dust hoods.
2. CONCRETE WORK & POUR CONSOLIDATION
Pouring ground slabs, retaining walls, and ring beams requires continuous consolidation to eliminate trapped honeycombing around reinforcing steel cages.
- Recommended Set: High-frequency concrete poker vibrator (38 mm or 50 mm needle), mechanical drive unit (petrol or 110V electric), beam screed or magic screed for top leveling, followed by walk-behind power float (trowel machine) for burnished finish.
- Operational Note: Concrete wait times are strict. Always stage a backup needle poker at the depot to prevent cold joints during pump truck placement.
3. GROUND PREPARATION & TRENCHING
Excavations for drainage, footings, and block paving demand compaction down through sub-base aggregates (MOT Type 1) to prevent long-term slab sinking.
- Recommended Set: Narrow-foot trench rammer (tamping rammer) for compacted cohesive soil around pipework, 180 kg reversible diesel plate compactor for crushed rock sub-base, and rotary laser level with receiver staff for grade checks.
- Operational Note: Compact in lift layers no deeper than 150 mm. Exceeding 150 mm per pass leaves soft subterranean pockets.
4. INTERIOR CONSTRUCTION & FIT-OUT
Interior fit-out requires dust-sealed electric systems, accurate leveling, and dry lining fixings without excessive jobsite noise.
- Recommended Set: Self-leveling 360-degree green beam multi-line laser, drywall drywall auto-feed collated screwdrivers, SDS-Plus compact rotary hammers for plug fixings, and M-Class mobile dust extractors with automatic filter pulsing.
5. FINISHING & SURFACE PREPARATION
Refurbishing deteriorated commercial screeds or removing failing ceramic tile beds prior to resilient flooring requires heavy mechanical abrasion.
- Recommended Set: 250 mm rotary single-head concrete floor grinder with medium bond diamond pads, long-handle pneumatic tile stripper, and heavy industrial 50 mm vacuum hose connection.
| Project Phase | Primary Machinery | Ancillary Support Needed | Key Hazard / Risk |
|---|---|---|---|
| Foundation & Sub-Base | Reversible Compactor (180kg) | Laser level, grade staff, trench rammer | Under-compaction causing slab settlement |
| Structural Opening | Diamond Wall Saw + 11kg Breaker | Water supply tank, Acrow props, wet vac | Vibration damage to masonry bonds |
| Slab Pour & Finish | Vibrating Poker + Walk-Behind Float | Spare flexible shaft, float pan blades | Plastic shrinkage cracks from late troweling |
| Interior Partitioning | Green Beam 3D Laser + Drywall Gun | Step podiums, collated screw belts | Misaligned stud centers and level errors |
