The key to achieving a detailed and useful set of submittal drawings is concise and continual communication between design professional and manufacturer.
The manufacturer shall submit samples, product data and submittal drawings of sufficient detail and scale to demonstrate compliance with the Grade specified.
The level of detail required on submittal drawings is established by the complexity of the project. The specifier is at liberty to specify any level of detail as a requirement of the project and of the contract documents. It should be noted that requirements for local codes and utilization of fire-retardant wood products is to be researched and directed by the design professional and are not the responsibility of the manufacturer. What constitutes the minimum expectation for a set of submittal drawings is not simple, since there are many variables as to the complexity, quality and type of work being specified.
For the design professional, the approval stage provides an opportunity, prior to fabrication, to review the manufacturer’s proposed engineering of the professional’s design intent. Submittal drawings, however, are not an extension of the design development process; therefore, changes by either party of intent or concept made during submittal drawing review may result in a change of cost and/or time.
During the review process the design professional should consider the following:
For the manufacturer, submittal drawings are drawings, diagrams, schedules and other data specifically prepared to illustrate their portion of the work. Their purpose is to demonstrate the way by which the manufacturer proposes to conform to the information given and the design concept expressed in the Contract Documents.
The four common levels of approval are:
Some design firms may elect to use the word Reviewed or Reviewed as Noted as a substitute for Approved.
Approvals are generally indicated by a stamp on the cover sheet of the submittal drawings. When selecting “Approved As Noted” rather than “Revise and Resubmit,” the design professional can often save weeks of production time provided the concept and all changes are clearly marked on the drawings.
Most projects are encumbered by a tight production schedule, especially for the finish trades such as woodworking, painting, carpeting and wall coverings. Prompt review of submittal drawings and accurate coordination of multiple trades can save weeks of time and eliminate problems before construction begins.
The design professional should work with the manufacturer through the contractor to determine the maximum “approval-to-fabrication” timeline needed to keep the job on schedule (e.g., “Submittal drawings must be returned approved to fabricate seven (7) days after submittal”).
Tabular Schedules vs Drawings - In some cases submittal drawings are not required to communicate the necessary quality, type, quantity and details of an item. Tabular schedules are used instead, generally for such items as doors, frames, stock factory cabinets, closet shelves, and furniture items. [example photo of tabular schedule]
It is the responsibility of the contractor to coordinate the manufacturer’s submittal drawings with work of all other trades and to ensure that hold-to/guaranteed dimensions are actually enforced.
It is the responsibility of the design professional or contractor, depending on contract relationships, to communicate design and field changes to all parties so that if dimensions are changed, each subcontractor can be held responsible for their work.
