About this file
This document outlines the scope of work for proofing structural design calculations and drawings for a federal construction project. The structural design must be proofed by an independent, licensed engineer to verify compliance with building codes and structural assumptions. The proofing engineer must disclose any conflicts of interest. As part of the proofing scope, the engineer will review calculations and drawings, provide remarks, and produce a report documenting the review process and confirmation that structural concerns have been addressed. Relatedly, the federal contract opportunity is a solicitation for a design-build project to construct a health clinic in Botswana, with an estimated construction budget between $250,000 and $500,000. The contract will be awarded on a best value basis in US dollars by the US Army Corps of Engineers European Command.

PROOFING OF STRUCTURAL DESIGN
SCOPE:
The structural calculations and drawings must be proofed by an independent proofing engineer, licensed as required for structural design in the HN of the appropriate discipline(s) (ie. Concrete, steel timber) at the contractor’s expense. A complete set of proofed and stamped structural design documents as well as the final structural proofing report must be submitted with the Corrected Final design submittal. For this purpose the A-E must coordinate early enough with the selected proofing engineer. A-E is responsible for ensuring proofing meets all requirements of the applicable building code The proofing engineer must be objective and independent from DOR. All conflicts of interest between the proofing engineer and the DOR must be disclosed to the COR prior to the start of the proofing process.
The proofing effort includes:
1. Proofing of the Structural Design Calculations and the verifications of structural fire protection.
2. Proofing of structural execution drawings, including but not limited to: Reinforcement drawings, structural Steel drawings, structural shop drawings, etc.
This task shall include the following deliverables at the final design stage:
1. Proofing Report(s):
The proofing report(s) need(s) to clearly document the proofing effort.
The Report shall list as a minimum:
A. Name, title, and address of proofing engineer
Name, title, and address of designer of record
B. Project name and location C. Complete list of proofed documents
If the proofing effort consists of different review phases the report shall be updated with each phase listing all proofed documents with dates of proofing effort.
D. Project Description E. Description of the structural system, including but not limited to: Foundation system, vertical forces resisting system, lateral forces resisting system, structural materials, etc.
F. Structural assumptions including but not limited to:
- Gravity Loads (dead load, live load, etc.).
- Environmental loads (wind, snow, rain, ice, etc.).
- Seismic loads and seismic design information (seismic zone, seismic design category, base shear, design spectrum, etc.).
- Soil data (allowable bearing capacity, subgrade reaction modulus, lateral earth pressures, etc.).
G. Applicable codes and regulations H. Findings:
- Interim proofing reports shall list in detail the technical findings and the required actions
- Final proofing reports shall document that all findings are addressed within the final design package.
If items still need to be addressed during execution, the report shall state so.
I. Final statement: The final statement shall summarize the proofing effort. If the proofing effort is completed the statement shall state that the proofing effort is completed and that there are no structural concerns against the execution in accordance with the proofed documents
J. Stamp and signature
2. Calculations:
Complete set of red lined proofed structural calculations with proofing remarks provided to the Designer of Record during the proofing process.
The set shall be stamped and signed on the title page by the Independent Proofing Engineer .
3. Drawings Complete set of structural red lined drawings with proofing remarks.
The set be stamped and signed on the title page by the Independent Proofing Engineer remarks provided to the Designer of Record during the proofing process.
The DOR shall demonstrate at the final design submittal that all structural proofing remarks are addressed within the final design documents. The final drawings shall receive a remark indicating that the independent proofing remarks are addressed.
