Shop Drawings
Catalyst develops shop drawings for pre–cast and cast–in–place bridges, concrete structures and steel structures.
Bridges
Catalyst provides Integrated Shop Drawings for Pre–cast and cast in place concrete bridges. Our range of expertise includes:
- Segmental Bridges
- Cable–Stayed Bridges
- Railroad & Mass Transit Bridges
- Concrete Girder Bridges
Our shop drawings include:
Reinforcing steel detailing, reinforcing list, bar bending details, post tensioning system detailing, duct shape and size, horizontal and vertical dimensioning, embedded items required for construction and any miscellaneous items referenced in the contract drawings.
We work directly with your Design Engineering Team or your CAD Manager as part of a team, working on a specific portion of a bridge or completing the full package.
Concrete Shop Drawings
Catalyst provides Integrated Shop Drawings for Pre-cast and cast-in place concrete structures.
Our range of expertise includes:
- Concrete Buildings in general.
- Beams, Columns, Footings, Corewalls, etc.
- Structural Stadium Components
- Insulated/Precast Wall Panels
- One and Two way Slabs
- Flat Slabs
- Post–Tensioned Slabs
- Slabs on–grade
- Formwork design and detailing
- Erection drawings
- Box Culverts
- Double–Ts
Our shop drawings include: reinforcing steel detailing, reinforcing list, bar bending details, post tensioning system detailing, duct shape and size, horizontal and vertical dimensioning, embedded items required for construction and any miscellaneous items referenced in the contract drawings.
We work directly with your Design Engineering Team or your CAD Manager as part of a team, working on a specific portion or completing the full package. We typically detail our concrete shop drawings with Bentley Rebar to achieve highly efficient bar bending schedules, 3D models and 2D views. Autocad and Microstationare also available
Steel Structures
Catalyst prepares two primary types of drawings: erection drawings and shop drawings.
Erection drawings are used to guide the steel erector on the construction site ("in the field") as to where and how to erect the fabricated steel members. These drawings usually show dimensioned plans to locate the steel members, and they often also show details with specific information and requirements, including all work that must be done in the field (such as bolting, welding or installing wedge anchors). Since the erection drawings are intended for use in the field, they contain very little specific information about the fabrication of any individual steel member; members should already be completed by the time the erection drawings are used.
Shop drawings, are used to specify the exact detailing requirements for fabricating each individual member (or "piece") of a structure, and are used by the steel fabricator to fabricate these members.
Our shop drawings show material specifications, member sizes, all required dimensions, welding, bolting, surface preparation and painting requirements, and any other information required to describe each completed member. The shop drawings are intended for use by the fabrication shop, and thus contain little or no information about the erection and installation of the steel members they depict; this information belongs in the erection drawings.
We comply with the requirements of the design drawings and with all industry standards and protocols, such as those established by the Australian Steel Institute, the American Institute of Steel Construction (AISC) and the American Welding Society (AWS).
