We have been providing companies like your own with shop and coordination drawings, which are accurate and thoughtfully ready. The services we provide include drawings for ductwork manufacturing, plumbing, HVAC piping, and electrical coordination. We make use of the latest Navisworks (BIM Modelling), Revit and other AutoCAD ™ Products as well as the latest MacsCad ™. This permits us to input information much faster than before, which provides us more time to analyse the job, slightly manipulate the drawings in order to save money on materials and labor in the field, and to ensure the quality of our work.

Scaled-down and smaller projects tend to be requiring coordinated shop sketches. Truth is, they always have, but now it is the GCs who are now requesting what has been in the specs all along. We get calls at MEP Precision Detailers every day asking “how fast are we able to get shop Coordination Drawing” for a number of small projects. Most of the subcontractors all say the same thing: “I don’t know why they’re asking for shop drawings, they never have in the past”, and their following question is “how much are they likely to cost”? Cost is really somewhat complicated, as we need to check out the project drawings, the specs,and the GCs requirements. On smaller jobs, the GC might not have specific requirements. In addition, it all boils down to whether you would like functional shop drawings or just a set of drawings to appease the requirement of the spec.

A shop drawing is really a drawing, or set of drawings, made by the contractor, supplier, producer, subcontractor or fabricator. Shop drawings are usually required for prefabricated elements. Examples of these consist of elevators, structural steel, trusses, pre-cast, home windows, appliances, cabinets, air conditioning units and millwork. Also,it is critical that the installation and coordinated shop drawings be completed by all the MEP trades, such as sheet metal ductwork, steam& heat piping, plumbing, fire protection and electrical. Architects and engineers, under their contract, do not produce shop drawingsfor the owner. The Mechanical Shop Drawings are to be from the manufacturer or the contractor, and it is their revised version of their particular systems they are installing, so it varies from the original contract construction design documents. The shop drawing usually shows more detail compared to construction documents. It is in the interest of the installing contractor to explain the details to the actual manufacturer’s production crew or the contractor’s installation crews. This type of the shop drawing is typically very different from that which came from the architect’s drawing. The MEP coordination drawings primary emphasis is to convey the particular product or set up, and they exclude notations regarding other products and installs, unless integration with the particular product is necessary.

Comparison information for that architect and engineer:

The shop drawings will include information for the builder and engineer to compare with the specifications and original contract drawings. The shop drawing should address the look, performance, and prescriptive descriptions within the specifications and construction sketches. The shop drawing often is more detailed than the information shown within the construction documents in order to provide the architect and engineer the opportunity to review the fabricator’s version ofthe product, prior to installation. References to the building documents, drawings, and specifications assist the architect and engineer with their review of the shop drawings. Attachment of manufacturer’s materials specifications, “catalogue cut sheets”, and other manufacturer’s information might be helpful to accompany these types of drawings. Because shop drawings help the architects and engineers approveof the product, they should be as clear and complete as possible.
