A contractor constructing a new reinforced concrete bridge required formwork for the abutment walls, bridge deck soffit and wing and parapet walls – three separate structural elements each with different geometry and loading requirements.
Using our technical expertise together with our versatile proprietary formwork systems, SEL’s in-house engineers provided the contractor with:
- Bespoke Temporary Works Designs to the BS 5975 standard
- Supply of the components required for the Frami and Dokaflex systems, along with a detailed inventory to control costs, and minimise waste
- Easy-to-follow assembly instructions
Abutment walls
The abutments were formed using Frami panel formwork across a 10.85m span. The panels were arranged to handle a pour height of 1,610mm at a maximum concrete pressure of 45kN/m², with push/pull props providing lateral stability. The system delivers an F2 finish as standard and can be lined for an enhanced fair-faced finish.
The bridge deck soffit
This was supported using the Dokaflex system. H20 timber beams at 488mm centres carried the deck load across a 1,760mm support height, with Eurex 30 floor props on lowering heads for controlled striking. The falsework was designed as a top-restrained system, tied back into the abutment walls.
Wing and parapet walls
We employed Frami panels for the wing and parapet walls. As standard with SEL Temporary Works Designs we also recommended safety and edge protection specific to the project in question.
