GENERAL GUIDELINES FOR PLAN SUBMITTALS & DOCUMENTSAll Plans and Documents Submitted for Permit which Detail Fire Protection Systems, asrequired by Chapter 9 of the Virginia Construction Code (VCC), must be prepared in accordance withthe following guidelines:1.Submitted plans drawn to a scale less than 1/8” 1” foot will not be accepted.2.For all plans, symbols and texts must be clearly legible and scaled appropriately for the size ofthe plan sheet. Any plans that are cluttered and not legible by the reviewer will be returned.3.Submitted plans shall be blueline (traditional blueprints) or blackline (black & white bondplots/prints) only. Color prints or plots will not be accepted.4.When executing the application for a permit, an applicant must provide a cogent, succinctdescription of work that captures the proposed scope accurately and quantitatively. “Fire alarmwork” or “Modification of sprinkler system” is not considered an acceptable description of theproposed work. “Modification to an existing fire alarm system, relocating x-number of devicesand adding x-number of new devices” is a best example.5.Data packages must be collated, assembled in sets, and bound with staples, brass fasteners,prong fasteners, or binder type folders. Spring clips and loose-leaf sets are not acceptable.6.Data packages must have an integral cover sheet using the installing contractors’ letterheadnoting the project address, complete scope of work narrative, and any other pertinentinformation. This requirement is particularly important for work that does not require a plan orshop drawing.7.The submission of rolled plans is discouraged as it is difficult to handle and temporarily store,while awaiting review, multiple sets bundled with “flat” material specifications. All submittedplans must be folded unless the number of drawings in the submission set cannot be physicallyfolded. In that case, rolled sets must be rolled face (drawing side) out so that staff may readthe title/address without unrolling the set.8.A building “key plan” must be provided on drawings to pinpoint the location in the building ofthe area shown on that drawing sheet.9.When submitting revised or as-built plans the applicant must provide one set of the previouslyapproved plans (to be returned). All revisions on all pages/sheets must be “clouded,” taggedwith a delta designation noting the revision date, and include an updated revision block, orplans cannot be reviewed.10. When resubmitting plans that have been rejected, the designer or responsible party mustsubmit a narrative noting corrective action taken to address each rejection comment issued bythe Office of Fire Marshal (OFM) plans examiner, or plans cannot be reviewed.11. The maximum number of plans that will be stamped and signed upon approval is three - oneset to be retained for record by the OFM and two sets to be returned to the applicant.12. Submit only two sets of hydraulic calculation print-outs - one set to be retained for record bythe OFM and one set to be returned to the applicant.13. Plans with OFM rejection stamps cannot be used as a revised submission with “handcorrections.”14. All plans must include the designer’s full name, email and phone number.NOTE: The Appendix contains all forms referenced throughout this document, as well as checklistswhich may aid in plan submission preparations.Code Reference Package for USBC 2015Page 6 of 75
