WEEKLY TAKEAWAYS AS A FIRE PROTECTION ENGINEER
|
Shop drawings (or installation drawings, fabrication drawings, or working plans) are a cornerstone of the fire protection industry. Prepared by or under the installation contractor, this design package contains the most important details concerning the design of fire sprinkler systems.
Enforceable Minimums NFPA 13 has specific requirements to what is required for a shop drawing submittal. It is enforceable by the Authority Having Jurisdiction anywhere that NFPA 13 is used as the reference standard. Below is a basic checklist for items that are required to be indicated in a shop drawing package, with references to whichever edition of NFPA 13 is being used. 
There's many items required to be included in a set of shop drawings beyond just the basic design parameters.
Don't Be A Jerk Unfortunately I have seen these references abused - an engineer rejecting submittals for not including a graphic scale, for instance, which does nothing to improve the technical content of the submittal but does adequately upset every person involved in a project. It is a rare submittal that achieves and includes every single aspect of the checklist (how often do you see a full-building section, for instance?). However, if you're a review party, review engineer, or shop drawing designer/engineer, this re-organized checklist with references may help clarify expectations for the design package. Shop Drawing Checklist When using this tool, select the edition of NFPA 13 used in the red box on the right-hand side. The references and checkboxes will autopopulate based upon your selection.

Don't forget to look at any local requirements. A common one that is missed is submitting drawings that are stamped by a design professional. (i.e. PE or NICET level III for example)

Where does it say this is required? In my opinion shop drawings should not be sealed by a professional engineer because there is already an engineer of record on the project. By requiring the shop drawings to be sealed the engineer of record is just making it confusing as to who is responsible for the design. Why would another engineer seal a drawing that he did not design. All the sprinkler contractor should be doing is coordinating. I do agree that they should be prepared under the direction of a PE or NICET level III. A stamped letter saying this should be sufficient.

Since most shop drawing come as pdf and the scale is lost in the creation of the pdf, the graphic scale is important for spacing verification since most drawing do not contain dimension for all devices.
