How GDL works
The erection crew on your job
You run the project; GDL Steel erects the steel building. Working from the manufacturer’s erection drawings, the crew stands the main frames on the anchor bolts, ties them together with purlins, girts and bracing, and closes the building in with roof and wall panels and trim.
GDL works on commercial and industrial buildings, and on residential and agricultural ones. The service areas page lists the towns of recent commercial jobs in Colorado, Nebraska, Utah and Nevada.
- Main frames, purlins, girts and bracing
- Roof and wall panels and trim
- Commercial, industrial, residential and agricultural buildings

For a bid
What to send with a bid invitation
An erection price rests on the drawings and on who does what on site. Whatever the invitation leaves open has to be assumed in the price.
- The drawings. The manufacturer’s erection drawings or building drawings, and the anchor bolt plan.
- The building package. Who supplies the building, and when it’s due on site.
- The site. The address, how trucks and lifts reach the building pad, and where the steel can be laid out.
- The schedule. The bid date, when the foundation will be ready, and when steel needs to be up.
- The scope lines. Which of these fall to the erector: unloading the steel, supplying lifts and any crane, and installing doors, insulation and liner panels.
- The contacts. Your company, the project name and the person running the job.
Before steel goes up
What OSHA asks of the general contractor
OSHA’s steel erection rule gives some duties to the controlling contractor: a prime contractor, general contractor, construction manager or any other legal entity with overall responsibility for the project’s planning, quality and completion. 29 CFR 1926.752 and 1926.755(b) set out the ones below.
- Concrete strength, in writing. Before erection starts, the erector gets written notice that the concrete in the footings, piers and walls, and the mortar in the masonry piers and walls, has reached either 75 percent of the intended minimum compressive design strength or enough strength to support the loads imposed during steel erection. That strength is based on an appropriate ASTM standard test method of field-cured samples, and the erector can’t erect steel without the notice.
- Anchor bolt changes, in writing. Anchor bolts can’t be repaired, replaced or field-modified without the approval of the project structural engineer of record. The notice before erection starts also confirms that any such work followed this rule, and before a column goes up, the erector gets written notice of any repair, replacement or modification to that column’s anchor bolts.
- Access roads. Adequate roads into and through the site for safely delivering and moving derricks, cranes, trucks, other necessary equipment and the materials to be erected, with a way to control foot and vehicle traffic.
- A laydown and work area. A firm, properly graded and drained area, readily accessible to the work, with enough space for safe storage of materials and safe operation of the erector’s equipment.

From the slab to the roof

Glade Park, Colorado
A slab before the steel
Anchor bolts in the concrete and scaffolding on site, before the frames go up.
Why it matters: Steel goes up on a finished foundation with its anchor bolts already set, so the concrete comes first. Here the slab is poured, with a level set up on a tripod.
Littleton, Colorado
A long frame, bay by bay
Purlins and girts between the frames of a long building.
Why it matters: A long building goes up bay by bay: purlins and girts tie each frame to the next before any roof or wall panel goes on.
Near Mullen, Nebraska
Several roof lines on steel
Lodge-style buildings with stone wainscot and timber-style trim.
Why it matters: Steel buildings don’t have to look industrial. This one has several roof lines, dark walls, stone wainscot and timber-style trim around the windows.
