SUBJECT: HIGUERA STREET BRIDGE RECONSTRUCTION PROJECT—
CONSTRUCTION MANAGEMENT
CAO RECOMMENDATION
1. Authorize the CAO to execute an amendment to the agreement with Martin, Rivett& Olson
(formerly Martin&Kane)to increase environmental monitoring services.
2. Appropriate $ 142,000 from the unappropriated balance of the General Fund to support the
increased level of environmental monitoring.
DISCUSSION
On June 1, 2000, construction began on Higuera Street Bridge project. At that time, staff had
arranged for contract construction inspection and environmental monitoring services. Both of
these functions are to some degree dependant upon the operations of the contractor and the
conditions of the work site.
The contractor has installed a stream diversion to protect the creek from falling debris and
accidental spillage. This entails building a temporary dam and laying a pipe in the creek bed to
cavy the water through the work site. The contractor has been unable to seal the stream
diversion completely. Ongoing monitoring for fish, present in the deep pools of the channel, has
become necessary. Containment of the drilling spoils has also been a challenge requiring
ongoing monitoring to ensure that any spoils leaking from the walls during drilling are contained
or the operation is shut down and the problem rectified.
The original work scope for the environmental monitoring did not foresee the need for constant
monitoring. Generally, the monitors are on site full time at the beginning of a project until the
work methods are set up and refined to meet the environmental constraints. At that time, the
monitors can move to periodic checks during the day. With the numbers of fish and the
difficulty with drilling spoils, an environmental monitor has been required at all times. At the
current monitoring level, the monitors will run out of funding prior to the work being completed.
There has also been a small additional cost to retain the services of a bat specialist in conjunction
with the work. Monitoring is a required condition for our creek work and must be funded.
FISCAL IMPACT
The 1999-01 Financial Plan, Appendix B, page 204 provides $4,100,000 for the Higuera.Bridge
construction in year 2000-01. The budget included $450,000 for Construction Management.
That $450,000 has already been obligated for the construction inspection and the environmental
monitoring anticipated at the time of award for construction. With full time monitoring now a
potential need, the consultant has estimated an additional $172,000 will be required to provide

full time observation, including overtime, through November 1, 2000. If the situation improves,
the monitoring will be reduced to an appropriate level and the costs will be less.
This additional funding is not currently approved for Federal participation; however, it is eligible
for funding as a necessary part of the construction project. Staff will request participation from
the Federal Highway grant program at the time of project completion. Funding reimbursement is
not guaranteed as the additional cost will be subject to approval and available funds in the grant
progtam. At this time we are requesting the additional funding come from the General Fund.
Cost Sharing
1999-01 Budget Ci $$ Federal $$
General Fund Construction $3,650,000 $910,000 $2,740,000
Enterprise Fund Construction $80,000 $80,000
Construction Management $450,000 $90,000 $360,000
Sub total: $1,080,000 $3,100,000
TOTAL: $4,180,000
Anticipated Cost as of Jul `00 Ci $$ Federal $$
Promotional Funds $20,000 $20,000
Early Completion Bonus $60,000 $60,000
Reimbursement of Pkg Fund $55,000 $55,000
Construction $2,200,000 $825,000 $1,375,000
Construction Management $622,000 $262,0001 $360,000
Sub total: $1,222,000 1 $1,735,000
TOTAL: $2,957,000
Additional Funds Required:
1 $142,000 $0
(Difference between 1999-01 Budget and Anticipated Costs)
While the anticipated total costs do not exceed the original total budget, much of that original
funding was Federal Grant Funds. The Grant funds for the Bridge Replacement and
Rehabilitation Program are not a set amount but rather a percentage reimbursement of eligible
costs. With a decreased anticipated construction cost, the Federal grant funds dropped as well.
Impact on Fund Balance. Based on the 1999-01 Financial Plan Supplement and Council-
approved changes since then, the recommended appropriation of $142,000 will result in an
ending General Fund balance that is 21.7% of operating expenditures compared with our policy
minimum of 20%.
