Complete Shop Drawings

The basic principle of a glazing system shop drawing is to provide a vehicle that conveys to the end user the system manufacturer’s design intent. The shop drawing should also clearly indicate the necessary materials, performance requirements, method of construction and critical path to convert the raw materials to the finished and installed product.

A shop drawing for any glazing system is, in a sense, a story with pictures. The story should be complete and never leave the reader deprived of any information, even in the smallest of detail. The story must also be clearly illustrated and easily read, as there will be professionals from several and varied disciplines that have need of all or some portion of the intelligence contained within the document.

Task 1: Proposals Drawings

Proposal drawings are project specific of a typical condition on the project to represent the wall system profiles, reveals, trims and basic coordination with other relating trades.

Task 2: Floor Plans

The floor plans for the project should be based upon the most up-to-date information available from the project contract documents. Amendments should be applied as they arrive. Each floor plan should present the project column grid and clearly establish all building elements in relation to the grid. The location of each glazing system module should always be located to a grid line for general layout purposes and also to coordinate the work of other trades.

In development of the floor plans it is essential to coordinate the following:

    • Edge of slab geometry
    • Curb locations and thickness
    • Embeds, anchors and PT cables.

Woodbridge standards for floor plans:

  • Edge of slab, column locations, mullions, glass and anchors are drawings on individual drawings sheets “Utilities” and X Ref and layered on to individual floor plans.
  • Window frame numbers and door numbers should be referenced.

Task 3: Elevations & Sections

As elevations and sections are built, we develop the unit drawings concurrently and XRef into the elevation drawings, essentially acting as building blocks. Project exterior and interior elevations are used to establish alignment of building elements both vertically and horizontally and in relation to each other. The scale of the elevations should be large enough to clearly depict the scope of work and allow accurate identification of the required elements. Larger scale “pop-outs” can be utilized, as necessary, to augment areas of the typical elevations that may be too small to illustrate a building element.

We show the frame configuration, vertical and horizontal dimensions, detail marks, glass types, the frame location relative to the building grid, quantities required, floor levels where the frames are required and an architectural reference.

Task 4: Details

Details are developed with architectural intent typically referencing face of system dimensions to align with adjacent trades. Detail sheets form the backbone of the shop drawing. Each detail should be clear, concise and accurately portray the actual conditions, as they can be expected and required on every aspect of the project. Precise dimensions, layout and representation of surrounding and related material is extremely important, as many other trades will rely on this information to formulate their own course of action and scope of work.
When developing details, it is important to take in consideration:

  • Fabrication and installation tolerances of both the wall system and other trades
  • Architectural dimensions referenced on contract documents
  • Constructability
  • Replacement and repair considerations
