The Building Department conducts plan reviews of commercial structures under a "deferral" from the State Fire Marshal. A deferral means the Building Department exercises the authority of the State Fire Marshal's office, and our plan review of public and commercial buildings is governed by both Alaska statute and local ordinance. Most large communities in Alaska have a deferral.
Drawings and specifications submitted to the Building Official must be sufficient to clearly show the project in its entirety with emphasis on the following:
The minimum required drawings will vary greatly depending on the size, nature, and complexity of the project. Following are the minimum basic requirements. Additions and remodels may not require all of the following components.
Show proposed structure and any existing buildings or structures, all property lines with dimensions, all streets, easements, and setbacks. Show all water, sewer, electrical points of connection, proposed service routes, and existing utilities on the site. Show all required parking, drainage, and grading information (with reference to finish floor and adjacent streets). Indicate drainage inflow and outflow locations and specify areas required to be maintained for drainage purposes. Show north arrow. Indicate proposed and existing tank locations (oil, propane etc) showing distance to property lines, and distance to buildings and building openings. (Including underground tanks.)
Show all foundations and footings. Indicate size, locations, thicknesses, materials, and reinforcing. Show all embedded anchoring such as anchor bolts, hold downs, post bases, etc. Include soil bearing capacity and/or pile details.
Show all floors including basements. Show all rooms, with their use, occupancy designation, occupant load, over-all dimensions and locations of all structural elements and openings. Show all doors and windows. Provide door and window schedules. When appropriate, show fire rated occupancy separations, and draft stops.
Show all structural members, size, methods of attachment, location, and materials. Indicate characteristics of sheathing, slabs, or decking. Locate all lateral force-resisting elements. Include shear wall details and fastening schedules.
Show significant views and openings.
BUILDING SECTIONS AND WALL SECTIONS
Show materials of construction, non-rated and fire-rated assemblies and fire-rated penetrations. Show critical dimensions unless indicated elsewhere.
Show entire mechanical system. Include all units, their sizes, mounting details, all duct work and duct sizes. Indicate all fire dampers and fire-smoke dampers where required. Provide equipment schedules.
Show all fixtures, piping, slopes, materials and sizes. Show point of connections to site utilities.
Show all electrical fixtures (interior, exterior and site), exit signs, emergency lighting system (if required), short circuit requirements, wiring sizes and circuiting, grounding, panel schedules, single line diagrams, load calculations and fixture schedules. Show point of connection to utility.
Either on the drawings or in booklet form, further define construction components, covering materials and methods of construction, finishes, and all pertinent equipment. Schedules may be incorporated in project manual in lieu of on drawings.
ADDENDA AND CHANGES
The responsible design professional shall notify the building official of significant changes throughout the project and provide revised drawings, calculations or other appropriate documents prior to actual construction. For clarity, all revisions shall be clearly identified on the drawings or resubmitted as a new project.
If the documents do not meet the criteria of these guidelines, the building official may take any of the following actions:
Note: It is a violation of state law for the Building Department to accept incomplete plans and then to provide design services by providing the missing design elements. For more information see "When are stamped plans required?"
