Shop drawings and take-off
Member marks, connection details, bolt lists and cutting schedules developed from your design drawings and issued for approval.
Discipline 01 of 5
Structural Steel Fabrication & Installation
Primary and secondary structural steel, fabricated in our own workshop and erected on site by our own crews, from setting-out to final bolt-up.
Overview
Structural steel is the discipline the company was built on. Work starts from your design drawings, which we develop into shop drawings for approval before a single section is cut. Members are marked, cut, drilled, fitted and welded in the workshop, finished to the specified coating system, then delivered to site in erection sequence.
On site the same team sets out from the column grid, plumbs and levels the frame, torques the connections and hands over a surveyed structure with as-built marks that match the drawings. Because fabrication and erection sit under one roof, drawing queries, fit-up corrections and site changes are resolved without passing between companies.
Benefits
- One accountable party: The crew that welds the connection is the crew that bolts it up, so fit-up problems are corrected rather than argued over.
- Fewer drawing loops: Shop drawings are produced against the same take-off used for procurement, which keeps revisions and re-cuts down.
- Predictable site programme: Deliveries follow the erection sequence, so lifting plant is not standing idle waiting for the right member.
- Records that match the steel: Member marks, bolt grades and coating details are recorded as built and handed over with the structure.
01
Key features
What the scope actually includes.
Six things we do as standard on this discipline, not optional extras priced later.
02
Cutting, drilling and fitting
Beams, columns, plates and hollow sections prepared to length, with holes and cleats set out from the same marked drawing.
03
Welding to procedure
Fillet and butt welds carried out by trade-tested welders working to an agreed procedure and visual acceptance criteria.
04
Surface treatment
Blast or mechanical preparation followed by the specified primer and finish, or hot-dip galvanising through approved applicators.
05
Delivery in erection sequence
Loads batched frame by frame so the crane lifts in the order the crew needs them, not in the order the workshop finished them.
06
Erection, alignment and bolt-up
Setting-out from the column grid, plumbing and levelling, permanent bracing, torqued connections and a surveyed handover.
