CHAPTER 3
PRE-DESIGN, DESIGN AND POST-DESIGN SERVICES
3-1
PRE-DESIGN SERVICES. See UFC 3-100-10N, Design: General
Architectural And Interior Design Requirements.
3-2
DESIGN SERVICES. These are the customary services provided by the
structural engineer for the design of a building, and they include the following:
3-2.1
Structural Basis of Design. Provide a narrative report on how the design
concept satisfies the customer's requirements, meets criteria and is cost effective.
Include statements on the following:
3-2.1.1 List a summary of the criteria upon which the structural design will be based.
Include a statement of live loading to be used, to include floor loads, wind, snow,
earthquake, etc., with references to justify the criteria used.
3-2.1.2 List all assumptions required for the structural design where the design
criteria is undefined, unclear, conflicting, or unknown. State the basis for the
assumption made.
3-2.1.3 Describe the gravity and lateral load structural systems selected for all
facilities to be constructed, and explain why it was selected. Provide all pertinent
information, such as capacity, size, dimensions, and a list of material selected with
design strengths.
3-2.1.4 Provide a narrative summary of the type of foundation to be used, method by
which the allowable bearing values are to be determined, and maximum allowable
bearing capacity and lateral-force resisting capacity of the foundations, as well as other
allowable soil parameters used in the design.
3-2.1.5 Describe the structural floor and roof systems proposed. Include a description
of the lateral force resisting system with appropriate materials and dimensions. Clearly
describe the load path to the foundation for both the vertical and the lateral-force
resisting system. Include definitions of the manner in which foundations and slabs on
grade are used to distribute lateral forces between the structure and the ground.
3-2.1.6 When appropriate, provide a statement of any special considerations that
affect the design (e.g., "superflat floors" for high stacking warehouses, special corrosion
resistance requirements, fire-resistive requirements, retractable roofs, crane or
monorail, etc.).
3-2.2
Specifications. See UFC 1-300-09N, Design Procedures.
3-2.3
Drawings. See UFC 1-300-09N, Design Procedures. Structural drawings
should be provided that sufficiently define and detail all structural work.
