CALTRANS FOUNDATION MANUAL
All utility locations shown on the plans should be verified with the utility representative.
The Contractor should notify the proper agencies to have the existing underground utilities
located in the field prior to commencing excavation operations. The status of utilities not
yet relocated and field evidence of additional utilities must also be discussed. Problems in
this area could result in serious delays. Hence, if they are not solved at the pre-construction
conference, they should be resolved at the earliest possible time.
The Contractor’s proposed methods of performing foundation work adjacent to utilities
should also be covered at the pre-construction conference. All present should be advised of
any proposed change orders affecting their work or property.
All pre-construction conferences should be well documented. When appropriate, minutes of
the meeting should be distributed to all attendees. This serves to confirm positions and/or
agreements made at the meeting.
Proposed foundation changes, whether the result of geologic or non-geologic conditions,
should be discussed with the Bridge Construction Engineer. Depending on the extent of the
proposed change, it may be advisable to consult with the Project Designer and the Engi-
neering Geologist.
Certain revisions in excavation limits, footing elevations and sizes, and revisions to or
elimination of seal course concrete are not considered contract changes. Written direction
can be given to the Contractor to implement various changes without the immediate need
for a change order. However, this situation is limited to instances where only contract items
are affected. As most items are final pay items, a change order will ultimately be needed in
order to allow the quantity change (refer to Bridge Construction Memo 2-9.0).
In actual practice, change orders are almost always issued to cover footing revisions. Once it
is determined that a change is necessary, the Contractor is issued a change order describing
the work to be done, the basis of compensation and the extent of any time extension.
To eliminate any possible misunderstanding about field revisions of foundations, a letter
should be sent to the Contractor prior to commencing foundation operations, advising of
the following (refer to Bridge Construction Memo 2-9.0):
