Formwork and Shoring

Formwork for walls, columns, pier caps, bridge decks and structural slabs. Multi-storey shoring and reshoring, slab capacity analysis. We work with catalogue equipment and with custom steel alike, whichever best serves your schedule and your budget.

Passive Shoring and Bridge Lifting

Transfer of transient loads, hydraulic jacking procedures, mobile-crane lift plans. Bridges, building frames and heavy equipment.

Mobile Crane Lifting

Lift plan, bearing capacity under the outriggers, spreader mats and sequencing when several machines work together. Single-crane, tandem, confined-space and pick-and-carry lifts.

Temporary Bridges

Design of detour structures, bridge launching from the abutment, and construction overload analysis on an existing structure.

Scaffolding, Enclosures and Access

Ringlock or frame scaffolding, short- and long-span enclosures, suspended platforms, scaffold-supported platforms and bracket platforms.

Earth Retention and Cofferdams

Sheet piles, soldier-pile walls, concrete blocks, reinforced soil. Watercourse diversion and watertight systems for work below the waterline.

Work Methods and Engineering Documentation

Demolition and erection procedures, sequencing, stability analyses, and the calculations, drawings and certificates that go with the method.
