Where a professional forester has taken design responsibility for a bridge,
a professional forester or a professional engineer must provide a signed and
sealed statement that the bridge is in general conformance with the design
drawings and specifications.
Where a professional engineer has taken design responsibility for a bridge,
a professional engineer must provide a signed and sealed statement that the
bridge is in general conformance with the design drawings and specifications.
A sample statement of construction conformance is located in Appendix 4.
Documentation of materials used, and as-built records for the bridge or major
culvert, should be obtained during fabrication and construction. The person
responsible for construction should obtain and retain as-built records, including:
• any pile driving records, hammer type, penetration, set criteria, etc.
• fabrication plant inspection reports, including mill test certificates, concrete
test results, etc.
• shop or as-built fabrication drawings
• concrete and grout test results
• field compaction results
• other pertinent fabrication, field, and construction data.
As-built drawings are the “approved for construction” drawings—which may
be the approved design drawings—marked up to show all significant variations
from the original design. For example, mark-ups would show as constructed
details such as precise location in plan, finished pile depths, footing
elevations, deck and other finished elevations, finished dimensions, and configurations
of components. The as-built drawings should be signed (and
sealed, where applicable) by the individual taking responsibility for the as-constructed
structure being in general conformance with the design. Where the
original design has been modified, these drawings should have been amended
by the designer, before inserting the as-built notes and details.
The as-built drawings, materials records, fabrication documentation, and
other field and construction documentation must be retained for the life of
the structure.
