REPORT TO CITY COUNCIL
TO: HONORABLE MAYOR
AND MEMBERS OF THE CITY COUNCIL
FROM: ROBERT A. BRADY

SUBJECT: INTERCHANGE IMPROVEMENTS AT INTERSTATE 1 -15 AND
CENTRAL AVENUE (SR -74) — CHANGE ORDER NO. 1 FOR
SURVEYING AND CHANGE ORDER NO. 2 FOR SOILS TESTING
CONSULTANTS
Background
On August 26, 2008, the City Council awarded a construction contract to Ortiz
Enterprise, Inc. in the amount of $2,896,591.30 for the construction of improvements to
the I- 15/SR -74 interchange. This priority project will provide for additional traffic lanes
on the freeway ramps as well as under the freeway bridge. Construction contract
documents for this project required the City to furnish surveying and soil testing
activities to insure work is done in compliance with project plans and specifications.
The firm of KDM Meridian was selected to do the survey work and the firm City &
County Soil Engineering and Testing provided materials testing services.
Discussion
During construction, staff determined additional soil was required to complete the slope
grading for the southbound on ramp. This change required additional testing and
inspection of the slope construction which was beyond the original contract scope of
work.
Survey work was required to determine the additional soil volume that was needed to
complete the slope grading on the southbound ramp. Additional survey was also
required for the storm drain culvert extension at Dexter Avenue and verification of the
bridge height for clearance over Central Avenue. This additional work was beyond the
original contract scope of work.
