Subfloor Access & Confined Working

Raising, re-levelling, restumping and underpinning existing houses - assessment, services disconnection, subfloor work, jacking and cribbing, stump and pier replacement and underpinning.

Setting up the work area around an occupied or vacated house, establishing access, laydown and exclusion zones, and setting out stump, pier and jacking positions for house raising and restumping works.

Manual handling of concrete and steel stumps, needle beams, cribbing timbers, props, jacks, bearers, cement bags, tools and equipment, much of it in a low subfloor across house raising and restumping works.

Assessing the house before it is lifted - bearers, joists, walls, chimneys, additions and connections - and preparing the engineer's jacking plan, lift sequence, monitoring and hold points.

Disconnecting, isolating and later reconnecting the electricity, gas, water, sewer, stormwater and telecommunications services to a house before and after it is raised or restumped.

Lifting a house on hydraulic jacks and needle beams in unified increments, cribbing as the lift proceeds, and holding it on cribs, props and beams until the new stumps or piers carry the load.
