Below is a list of projects for which the services would be used:

MTC Engineering, Inc. is a geotechnical consulting firm that provides testing of concrete strength, compaction of asphalt-concrete (AC) pavement, batch plant inspection, measurement of soils and rock index properties, and other appurtenant testing and analysis related to construction. Such testing and reporting are necessary to ensure both proper construction materials and workmanship.

Background:

In December 2000, Staff received three proposals for geological analysis reporting for Project No. CIP 95-507 Valley Park Improvements. The proposals were to furnish geotechnical data and analysis for the proposed new restroom building at Valley Park. After reviewing the proposals, MTC Engineering, Inc. was selected since it provided the most comprehensive services. The proposals are available in the Department of Public Works for review.

Since MTC Engineering, Inc. provided the City with the satisfactory geotechnical analysis for the restroom building at Valley Park, the City established an On-Going Services Agreement with MTC Engineering, Inc. in July 2001. Under the terms of the agreement, the expenditure in one fiscal year must not exceed $10,000.

MTC Engineering, Inc. has taken five core samples from Monterey Boulevard between Pier Avenue and 20th Street and 3 core samples from Hermosa Avenue between Pier Avenue and 16th Street. From those eight core samples, they have provided a geotechnical report. Furthermore, they conducted on-site compaction tests during the placement of leveling course and rubberized asphalt-concrete, taken fourteen core samples, and provided the geotechnical report for Hermosa Avenue from 16th Street to 26th Street and 19th Street from Hermosa Avenue to Monterey Boulevard. Staff recommends that similar testing and reporting be done for Manhattan Avenue Street Improvements which is scheduled for construction in November 2001.

Staff had anticipated that these professional services would not exceed $10,000, however, more frequent on-site compaction tests and additional detailed geotechnical reports are needed than originally anticipated. Therefore, Staff recommends that Council approve the PSA between the City and MTC Engineering Inc. for $20,000 in lieu of the On-Going Services Agreement.

Fiscal Impact:

No additional appropriation is needed.
