APB have extensive experience in the undertaking of ground works and reinforced concrete elements on civil engineering projects.

Reinforced concrete forms a part of most civil engineering projects undertaken by APB. Whether there a requirement for Reinforced concrete foundations, reinforced concrete retaining walls or in-situ reinforced concrete structures APB have the knowledge and expertise to undertake.

Ground works are undertaken by our CSCS and CPCS trained engineering staff and operatives who start by forming the base to the required levels and grades. Once the ground works have been undertaken and ground is prepared to the required standard APB can then tie reinforcing steelwork to the required drawings, before constructing formwork to the dimensions of the reinforced concrete foundation. Cast in items such as holding down bolts are then hung in the required location.

Concrete is placed through the use of truck mounted concrete pumps, static concrete pumps or wheel barrows and concrete is then troweled to the required finish.

Subsurface reinforced concrete structures have also been undertaken to construct a viewing gallery underneath a road to enable access to inspect bearings under live traffic. For this, groundworks were undertaken to excavate down to the required levels before tying the steel reinforcement and constructing formwork to the dimensions of the reinforced concrete foundation. Kickers were cast in to the concrete floor slab to allow the next section of reinforced concrete to be poured to form the rear wall. Soffit shutters were also constructed in order for the reinforced concrete to form the roof of the viewing gallery as well as the surface to which the traffic would run across.

Reinforced waterproof concrete lift pits have been constructed in the same way on live railway station platforms, with groundworks being undertaken first, before forming the reinforced concrete pit through the use of formwork panels. Reinforced concrete stair foundations were also constructed with cast in holding down bolts to enable to placement of a new steel bridge structure. Key to its success was the work of the operatives and the engineer in ensuring the new steel bridge would fit over the bolts in the cast in concrete.
