DEPT. CONSTRUCTION SUPPORT FOR THE MACARIO CANYON ENG BRIDGE, PROJECT NO. 3184
DEPT. HD. 2 rg
RECOMMENDED ACTION:
Adopt Resolution No. 99‘ * I 5 1 approving Amendment No. 1 to an Agreement with
Woodward-Clyde International Americas to Provide Monitoring Services and Construction Support
for the Macario Canyon Bridge, Project No. 3184.
ITEM EXPLANATION:
The Engineering Department requires an amendment to the existing agreement with
Woodward-Clyde International Americas to provide monitoring services and construction support
for the Macario Canyon Bridge. On January 29, 1999, the City approved a contract with
Woodward-Clyde International Americas to provide the necessary monitoring services for the preparation of recommendations regarding the settlement of the Macario Canyon Bridge
embankment. During the construction of the project, additional recommendations from
Woodward-Clyde are necessary for the continued work on the Macario Canyon Bridge. Staff has
determined that additional subsurface exploration may result in cost savings for the project by
requiring shorter piles. The shorter piles will cost less for both supply and installation.
The Macario Canyon Bridge crosses the mouth of Macario Canyon. Prior to the initiation of
construction, the area was densely covered with wetland vegetation that could not be disturbed.
Limited subsurface exploration could be done. Work in the canyon has been initiated and the canyon in the area of the bridge foundation has been completely cleared, allowing the
geotechnical engineer access to the canyon. During the pile driving phase of the project, piles were installed between fourteen and twenty-five feet less than their design depth. The ability to
access the site and perform additional subsurface exploration will allow a true design depth to be determined.
Due to environmental constraints imposed by the resource agencies, the pile driving operation has
been shut down until September 1, 1999. This allows subsurface exploration in the actual location
of the foundations.
Staff recommends approval of this amendment because Woodward-Clyde International Americas
is the geotechnical engineer of record, they have intimate familiarity with the project and current
issues and they have been working on the project consistently throughout the last ten years.
ENVIRONMENTAL REVIEW:
The Planning Director has determined that the requested action is consistent with prior CEQA review. The project was reviewed in the Cannon Road Reach 1 Environmental Impact Report,
Significant environmental impacts identified by those CEQA documents were determined to be
mitigable to levels of less than significant. Permits from the resource agencies have been reviewed.

FISCAL IMPACT:
The costs associated with the additional subsurface exploration are $5,400. The current
agreement is for $24,970. Approval of the amendment increases the contract total to $30,370. It is estimated that the cost saving of the manufacture and installation shorter pile for the bridge
foundation will be approximately $25,000. Sufficient funds are available in the Cannon Road West
project account.

DEPARTMENT
Dear Ms. Howard:
URS Greiner Woodward Clyde (URSGWC) is submitting this proposal at your request to
perform additional geotechnical explorations at the subject site. We had previously performed a
geotechnical investigation for this bridge. The results of that investigation, and our
recommendations for design, are presented in our report dated January 10, 1989 (Woodward-
Clyde Project No. 8751455R-X02). At the time of our geotechnical investigation in 1989, the
canyon bottom was densely vegetated with ws, brush and reeds. This, and environmental
constraints, limited the areas that were accessible for subsurface explorations at the time of the
design. As a result, the subsurface conditions at Piers 3, 4 and 5 had to be estimated by
interpolating between borings that were spaced 180 feet from each other. Recognizing the
potential variability in the actual subsurfaw conditions, we had recommended that steel H-piles
be used for the foundations, and provisions be made to allow for cutoff or adding to the piles.
The piles for Pier 3 Right and Pier 4 Left have recently been driven. The piles at Pier 3 Right
met refusal 25 feet higher than our specified tip elevation. The piles at Pier 4 Left met practical
refusal 14 feet above specified tip.
For environmental reasons, the pile driving of the remainder of the piers will not commence until
later this year. We understand that it is desired to refine the estimated tip elevations at the
remaining piers to reduce the length of pile cutoffs that may be required. To further evaluate the
estimated tip elevations, we would profiose to perform three cone penetration tests (CPT). These
CpTs would be performed as close as possible to Pier 3 Left, Pier 4 Right, and Pier 5 Left; it is
estimated a total of approximately of 325 feet of sounding will be performed. We will utilize the
information from the CPTs to reevaluate the estimated pile tip elevations at those pier locations.
We will present the results of the CPTs arid our evaluations in a letter report.

s. Sherrie Howard
We could provide you with the letter report within one week of authorization to proceed, pending
availability of the CPT rig. We would propose to perform these additional explorations as a
modification to our existing contract to provide consultations for the Ma&o Bridge
construction. We estimate our cost for the additional explorations would not exceed $5,400.
If you have any questions regarding this proposal, please contact us.
Very truly yours, fi
