Multi-Storey Steel Bridge Delivery
The capability stack for designing and delivering a multi-storey urban steel bridge — typically rail, station, or grade-separated highway crossings. Eurocode 3 + UK NA design framework with site-practice content from welding, coatings, and rigging specialists.
Pricing model
Buy the full capability stack, or a single discipline slice.
Full Package = all 6 slices + curator-assembled coordination content + lead validator support. Single slice = one discipline for specialist firms. 2-3 slice bundles negotiated case-by-case.

6 discipline slices · all chartership-validated · paired entries throughout.
Steel bridge delivery is dominated by tier-1 contractors with deep welding + coatings supply chains. Mid-sized civil-structural firms wanting to enter typically lack the site-practice depth on weld inspection, intumescent coating application, and complex lift planning. This Package consolidates that capability stack.
The six slices
Each slice is individually purchasable for specialist firms. Premium slices (Technical Interfaces — coordination knowledge) command higher pricing because the knowledge is structurally rarer.
Civil
Substructure and approach earthworks: pile design for heavily loaded bridge piers, abutment geotechnics, approach embankment stability.

Same product. Different urgency.
If you're growth-seeking
The alternative growth path
UK infrastructure procurement increasingly bundles steel bridges into £100M+ frameworks accessible only to tier-1s. Mid-sized civil-structural specialists can offer joint-venture bids — but only if they have the technical depth across welding, coatings, and rigging. This Package gives them that depth.
Built for: Mid-sized civil-structural firms (£15-60M revenue) wanting to bid for HS2, Network Rail Control Period 7, or major TfL infrastructure renewals.
If you're pivoting under pressure
Before administration · the survival pivot
Traditional highway-bridge civil firm whose primary client (a tier-1 framework contractor) has paused its forward order book. Rail infrastructure is in a sustained capital cycle — HS2 + Network Rail CP7 + Elizabeth Line continuations. The civil-structural capability you already have transfers; what you lack is the welding/coatings/lift-planning depth this Package consolidates. Pivot route to bid for rail station work in 90 days instead of 12-18 months organic skill build.
UK construction administration counts have been elevated since 2022. EngTree Packages exist for firms that need to pivot 90 days before they hit the cliff, not 18 months after.

We'll introduce you to firms with the rest.
Stage 2: when multiple firms buy complementary slices of the same Project Package, EngTree's matchmaking algorithm flags the pair as a candidate joint-venture or bid-team match. The platform becomes the discovery layer for JV opportunities previously gated by network or geography.
Matchmaking is opt-in. Anonymous-until-introduction. GDPR-respectful.
