Contract Amendment #4
Revised 8/28/07
ARTICLE 4, COMPENSATION
The total compensation for this agreement shall be increased by $129,100 for a total Camino Arroyo contract not
to exceed amount of $918,479.
EXHIBIT "A" SCOPE OF SERVICES AMENDMENTS
1.1 Project Management
Dokken Engineering will perform additional project management activities to quickly incorporate
streetscape design features from an additional sub-consultant. Also included are meetings with the City
staff necessary to complete the project phases I and II.
3.3 Utility Potholing
Cruz Brothers Locators will perform 6 additional utility potholes at $1000 each (for a total of 21) along
Sixth Street to confirm the location of existing facilities that are in conflict with the revised storm drain
systems. After potholing is complete, the roadway will be repaired using hot patch asphalt concrete.
These additional 6 potholes were determined to be necessary during the potholing operations as
existing unmarked and unreported utility conditions were encountered. Dokken Engineering felt these
additional potholes were important to minimize construction surprises associated with the storm drain
inlet, pipe and manhole adjustments being designed.
Nathan Donnelly will spend 2 days on site with the potholing crew to denote changes to the Sixth Street
storm drains necessitated by the potholing results. Nathan will also direct the need for supplemental
potholes determined necessary during the progression of work and as related to unmapped or
abandoned facilities. While on site Nathan will layout the configuration of a typical curb ramp for City
review. This review resulted in the identification of the need to enhance the curb extensions with
additional streetscape concepts.
3.6 Right of Way Acquisition
Dokken Engineering provided additional Right-of-Way management services to coordinate extended
negotiations with the commercial real estate owners of three parcels. This included twice weekly calls
to attorneys, managing partners, the City and Universal Field Services to obtain completed agreements
for the three parcels.
While minor revisions to plat maps and legal descriptions are included in the original contract with Ross
Stephenson, resolution with South County Ventures, Costco, and Inland Western Gilroy required
numerous format and grammatical changes to the plat map and legal descriptions. Additionally, a
Temporary Construction Easement was added to the South County Ventures Parcel.
4.4 Utility Coordination
Dokken Engineering has attended two additional field meetings with PG&E and Verizon in efforts to
coordinate the undergrounding, service points for the pillars, street lights and signals. This also
includes coordination with Verizon to perform clean-up design adjacent to the Sixth Street Overcrossing
in cooperation with City Trail on the bridge and approach work.
4.5 Gilman Avenue Overcrosslng Improvements
Preparation of structural analysis for additional dead loading on the overcrossing for the City Trail
features. Dokken Engineering will prepare the structural analysis, design, and details for submittal to
Caltrans Encroachment Permits and Division of Structures for the approval of trail revisions on the
overcrossing. Modification of the overcrossing to accommodate a 10 foot City Trail requires the
addition of a concrete traffic barrier and widening of the eastbound sidewalk to 10 feet. Caltrans is
concerned that this bridge already does not meet current code requirements for shear design, and that
DOKKEN
EXHIBIT A, Scope of Services Amendments
this additional weight will worsen this condition. Dokken Engineering will prepare calculations and
details to increase the shear capacity of the critical girders in the bridge.
4.6 Traffic Calming Construction Details
Additional Sixth Street Improvements at Railroad Street, Rogers Lane and Maple Street will be designed
by Dokken Engineering. Design of these additional improvements includes curb extension layouts,
curb ramp detailing, curb and gutter, drainage modifications, striping revisions, streetscape
coordination and quantity calculations.
4.7 Street lighting Design
Prepare new decorative and standard cobra street lighting standards for the City of Gilroy. The
standards address 5 different street types. This will include the preparation of at least two standard
plan sheets
Prepare revised street lighting design, plans, quantities and specifications on Sixth Street, Gilman and
Camino Arroyo roadway segments. The revisions were to accommodate using decorative lighting at
certain locations.
5.7 Landscaping It Streetscape
Bellinger Foster Steinmetz will provide streetscape design to the curb extensions and planter strips
along Sixth Street from Railroad to Rogers. This scope of services includes Exhibit B "Scope of
Services" dated April 10, 2007 and "Additional Service Request" dated June 6, 2007, both prepared by
Lee Steinmetz.
(
Dokken Engineering will provide project background, existing topography files and sharing of design
files to support development of the streetscape plans as quickly as possible. Dokken will further be
responsible for PS&E coordination and revision of completed contract plans to incorporate the
streetscape plans, specifications and bid items prepared by Steinmetz into the contract documents.
