STRUCTURAL GLASS FACADES - USC School of Architecture

this point, potential design/build contractors can also be invited to provide preliminary costing
and budget confirmation.
3.3.1.7 Adjust the design as required to match cost with
budget
Evaluate cost against budget and consider design modifications as required. Depending
upon the initial design assumptions, less expensive alternatives for glass, glass system and
structure type may be possible.
3.3.1.8 Prepare a design/build bid package
Once a basic preliminary design is determined and evaluated for performance and cost,
performance-based bid documents as suitable for a design/build project delivery method can
be prepared.
3.3.2 Minimum Bid Documents for Design/Build Bid
Virtually all structural glass façade construction is ultimately completed under a design/build
project delivery method as discussed above, regardless of the scope of work provided by the
design team. Most or little of the design work can be provided by the architect, but the
design/builder is generally responsible for final design and engineering, acting as engineerof-record
for the façade work.
The function of the performance-based bid package is to communicate as clearly as possible
the architect’s design intent, while leaving flexibility in the final design and detailing, which
will be the responsibility of the design/builder subject to review and approval by the architect.
