Erection drawings – the site's map to the structure

Anchor bolt plans, framing plans, cross-sections, sheeting layouts, bolt lists and the erection sequence – with piece marks that match every shipped member, so the site crew knows exactly what goes where, and in which order.

Sample roof framing erection plan with member marks and sequence

What erection drawings are

Erection drawings show the site how to assemble the structure: where each piece goes, how it is connected and in what order. Every member carries the same piece mark on the drawing, on the steel and on the packing list, so pieces are found, lifted and placed without guesswork.

They are generated from the 3D model, issued for construction with the first shipment, and supported by our erection method and, on request, by our site supervisors.

Contents

What the erection set contains

Typical sheets – depending on the structure.

foundations

Anchor bolt plan

Anchor bolt layout, projections, base plate orientation and grout.

roof · walls

Framing plans

Roof and wall framing with member marks, bracing and purlin laps.

frames

Cross-sections

Each frame type with marks, splices and connection references.

phases

Erection sequence

Order of erection by bay and phase, matched to shipments.

connections

Bolt schedule

Bolts by connection with grade and tightening – snug-tight or pretensioned.

envelope

Sheeting & trims

Panel layouts, laps, fasteners, flashings, gutters and downpipes.

Applicazioni

Why good erection drawings save time on site

Find every piece

Piece marks link drawings, steel and packing lists.

Right bolt, right torque

Bolt sizes, grades and tightening method listed by connection.

Safe sequence

Start from the braced bay; temporary stability considered.

Cladding that fits

Sheeting, flashing and trim layouts with fastener patterns.

Fewer site queries

Clear plans and details answer questions before they are asked.

Basis for as-built

Site changes recorded against the erection drawings.

Design workflow · step 5 of 6

Where this fits in our design workflow

Erection drawings are step 5 of our six-step design workflow. They come from the same 3D model as the shop drawings, so every piece mark on site matches the piece made in the factory – and site changes recorded on them become the as-built drawings (step 6).

Il flusso di progettazione World Steel

Punto di arresto dopo la fase 2: nulla viene fabbricato prima che i disegni di approvazione siano approvati.

Bolted end-plate connection in the 3D model

Bolting

Bolts and tightening, connection by connection

Bolt schedules list every connection with bolt size, grade, length, washers and the tightening category required by the design – snug-tight or pretensioned to AISC / RCSC, AS 4100 or EN 1090-2 – so the site installs and inspects bolts to the same rules the engineer designed.

FAQ

Domande frequenti

When do we receive the erection drawings?

Before the first shipment arrives, so the site team can plan cranes, lay-down and sequence.

Do you provide an erection method statement?

Yes, on request – including sequence, temporary bracing and lifting information – and site supervision can be arranged.

How do you handle changes on site?

Site changes are recorded, approved and incorporated in the as-built drawings at handover.
