Building code

Consultation

Pre-Design

establish parameters

  • Determine Authorities having Jurisdiction (AHJ) for zoning and/or building codes
  • Research and summarize zoning regulations.
  • Research and summarize applicable code (building (existing), energy conservation, plumbing, accessibility, health, etc)
  • Obtain existing conditions information (site survey, existing building drawings, and photos)
  • Determine if zoning requires an appeal or conditional use hearing.
  • Establish building code project type (new construction, addition, change of occupancy, or alteration level I, II, or III).

Preliminary Analysis

using parameters established in Pre Design

  • Determine final/resulting occupancy type(s) (A1, A2, A3, A4, A5, B, E, F1, F2, H1, H2, H3, H4, H5, l1, l2, l3, l4, M, R1, R2, R3, R4, S1, S2, U)
  • Determine existing or desired building height (in feet from grade plane to mean roof height and stories above grade plane) and area (bound by an interior surface of exterior or ‘fire walls’ per story including projection of floor or roof above)
  • Determine if occupancy required fire suppression throughout ‘building’ or ‘fire area’.
  • Determine if allowable building area may be increased due to open perimeter > 20′ from building exterior walls to a property line, centerline of a right-of-way, imaginary property line (where > single building on same lot) or unbuildable easement.
  • Determine options for construction type based upon occupancy, building height, building area and if fire suppression is present throughout ‘building’, and if occupancies are non-separated, separated by ‘fire barriers/horizontal assemblies’ or ‘fire walls’.
  • Determine if building could be classified as an ‘unlimited area building’ if appropriate occupancy type, construction type, one or two stories, open perimeter of 60 feet (40 feet for up to 75% of perimeter if meet three conditions) on all sides of building and has zoned fire suppression throughout.
  • Determine if portions of the building require accessibility improvements (exterior, entry, toilets, elevator/lift, circulation paths, doors).
  • Determine mandatory and prescriptive requirements of energy conversation code for building envelope, mechanical systems, service water heating, and electrical and lighting systems.

Outline analysis in .dwg file format

text and graphic file that may be incorporated into designer’s drawings

  • Obtain a copy of preliminary drawings from the designer (minimum of site plan, floor plans, exterior elevations).
  • Develop an outline analysis of major aspects of building, accessibility, and energy conservation codes that apply to the project. Note items on outline analysis that have options that must be determined/selected by the designer.
  • Add or modify items in the outline analysis to match specific project conditions and decisions made by the designer.

Construction Document review

review progress and or final construction documents

  • Obtain copies of progress and final construction documents from designers (including engineering consultants)
  • Review documents for more specific code related compliance details
  • Correspond with designer via written or graphic comment regarding specific requirements
  • Update outline analysis as more detailed document development requires
  • Complete final version of outline analysis and share with client

Authority Having Jurisdiction (AHJ) correspondence

written or verbal

  • Respond to written or verbal document submission review comments by AHJ’s
  • Provide written, graphic or verbal support to designer during correspondence with AHJ’s

Construction phase consultation

  • Respond to written or verbal questions from designer (re: AHJ or contractor RFI’s)
  • Participate in or conduct on site inspections regarding code related issues
