LOCAL PREFERENCE IN AWARDING CONTRACTS A brief summary was given on the current procedure for awarding consulting service contracts. Currently, points for familiarity with the area and the City are given, but no points are given for local firms or for those AGENDA SUMMARY REPORT BUDGET AND FINANCE COMMITTEE Monday, September 18, 1995 Page -2- that use local subcontractors. Staff provided examples of the current consulting services scoring method and the proposed scoring method which includes local preference points. The current system uses the pdce of services as a tie breaker, if two companies have very close scores. The Committee indicated that the issue was determining what weight to give to local preference as a percentage of the total score. Both the Committee and staff agreed that 5% of the total score is reasonable. Staff was directed to revise their scoring method so that local companies and/or using local subcontractors would count as a maximum of 5% of the total score for consulting contracts. 6, NEW BUSINESS A. LONG-TERM MAINTENANCE FOR TRAILS PLAN Staff distributed an outline of the issues regarding the maintenance of trails which are apart of the draft Specific Trails Plan recently completed by staff. The three funding options proposed for long-term maintenance include the General Fund, Maintenance Districts or Homeowners Associations. Funding trail maintenance through maintenance districts would cost residents in the area of benefit for the trails, between $19 to $22 per unit annually. The Committee felt that this was not a viable solution to the trails maintenance issue. It was further stated that the City would not have any assurance es to the quality of maintenance or if it would be done at ail, if left to homeowners associations. Since the Committee was not asked to take action at this time, staff was asked to continue to research the issue and explore other options. B. PERFORMANCE COMPENSATION FOR CONVENTION CENTER HVAC CONTRACT The Committee reviewed a memo regarding the options for including a performance bonus program in the contract with Honeywell for the design/build of the Convention Center HVAC. The memo provided draft language which stated that if in any phase of the work, the consultant is able to complete the work at a cost. less than the agreed upon price, that the savings will be split 50/50 between the City and the Consultant. Both staff and the Committee expressed concern that the performance incentive AGENDA SUMMARY REPORT BUDGET AND FINANCE COMMITTEE Monday, September 18, 1995 Page -3- could lead to the consultant cuffing corners and providing a product which could have a much shorter useful life. The HVAC project is time-sensitive and, therefore, staff was directed to return to the Committee, prior to negotiating the final price for the work with Honeywell, to make a recommendation on the specifics of an appropriate incentive program. 7.

William Henry SUBJECT Police Response to School Alarms The Bakersfield Police Department currently services five school districts; Bakersfield City, Fruitvale, Panama-Buena Vista, Greenfield, and Kern High School. These districts account for 56 school sites, having a total of 196 alarm permits.. During the 1994/95 school year (September through June), the schools were billed $31,230 for police response to false alarms. Currently, alarm response procedures allow the first four false alarms in a 12 month period free (not billed) at each site. The cost for five through ten alarms is $100 each, and 11 or more is $175 each. The fee is based on the average response time of police officers. A false alarm is defined as a response where attempted entry, or any other reason for activation could not be located. As of Calendar Year 1994, the police department responded to a total of 6,910 alarms city wide, 95% of which were false. Each school alarm generally requires three to four police units because of building layouts, and removes officers from service for a considerable amount of time.

Structural Inspection of Mechanical Room Slab Civic Auditorium Bakersfield, California For Honeywell August 30, 1995 By COLE/YEE/SCHUBERT & ASSOCIATES 2500 Venture Oaks Way, Suite 300 Sacramento, CA 95833 CYS Job No. 95165 Structural Inspection of Mechanical Room Slab Civic Auditorium Bakersfield, California CYS Job No. 95165 I. EXECUTIVE SUMMARY The existing reinforced concrete floor slab and exterior reinforced concrete wall at the mechanical room has been damaged by frequent exposure to a calcium chloride solution and is no longer acceptable for use. The damage to the slab and wall has been amplified by the constant vibration of the floor mounted mechanical equipment. The slab and supporting steel support beams should be shored to accommodate the movement of mechanical equipment. It is recommended that further investigation be conducted to determine the full extend of damage to the slab and wall and supporting structural elements. We further recommend that all affected structural elements be replaced or repaired prior to the installation of new mechanical equipment. H. INTRODUCTION Cole/Yee/Schubert and Associates undertook a structural investigation of the elevated concrete slab of the Mechanical Room at the Civic Auditorium, Bakersfield, California at the request of Mike Goodrich of Honeywell. The purpose of the investigation was to determine the capability of the existing slab to support the movement of mechanical equipment and to report our findings. Design drawings prepared by Wright, Metcalf & Parsons were reviewed as a part of our investigation. A cursory site visit was made on ~August 25, 1995. III. HISTORY AND DESCRIPTION The Civic Auditorium is a multi-use facility located in downtown Bakersfield, California. Originally constructed in 1962, the two-story structure is a concrete load-bearing shearwall building with steel framed floors and roof systems. The building was added to in 1987 and contains an auditorium and exhibition hall which accommodates cultural and sporting events. A calcium-chloride heat exchange system supported by mechanical room pumps and tanks provides the ability to make ice on the exhibition hall floor. IV. THE MECHANICAL ROOM FLOOR SYSTEM The mechanical room floor system was constructed in 1961 and consists of a one-way 4½ concrete slab reinforced with ~ rebar at 16 inches on center and is supported by steel beams and girders spaced approximately 8 feet on center. Some portions of the floor are supported by concrete walls at the interior and along the exterior east wall of the building. The design documents indicate a 28 day concrete strength of 2500 psi and a reinforcing steel yield strength of 40000 ps/. V. FINDINGS Inspection of the mechanical room slab revealed extensive damage to the 4½" concrete slab. The damage was concentrated at areas of the slab which support mechanical elements of the calcium- chloride cooling system (see sketch #1). The obvious slab deterioration showed as cracking, spauling and heaving (see photos #1 through g4). Inspection of the underside of the slab showed extensive iron oxide staining associated with cracks and some minor spauling (see photo #5). Inspection of the structural steel beams supporting the slab revealed no obvious signs of distress or deterioration. In addition, the adjacent exterior concrete wall displays signs of deterioration (see photo #6). Inspection of the wall (see photo #7) revealed cracking, spauling and iron oxide stains at the floor line. The damaged area of the exterior concrete wall is closely associated with the most highly deteriorated slab areas. Closer examination of the concrete spauls revealed that the steel reinforcement appears to have been corroded away at the floor line (see photo #8). Approximately three-fourths of the concrete slab and about 25 feet of exterior wall have been affected. VI. CONCLUSIONS It is our opinion that the existing concrete slab has been damaged by frequent exposure to the calcium-chloride solution, amplified by the constant vibration of floor supported mechanical equipment. The slab is no longer serviceable and it would be unwise to move heavy mechanical equipment across it without shoring the slab and support beams. VII. RECOMMENDATIONS Due to the advanced state of deterioration in both the slab and wall, we recommend further investigation to determine the extent of damage. Possible deterioration of the steel beams should be determined as well as the extent of corroded wall reinforcement. We further recommend that the affected portion of floor and wall, as determined by investigation, be replaced prior to the installation of new mechanical equipment. A repair and replacement option is provided in sketches 2, 3, & 4. VII. DISCLAIMER This report does not express or imply any warranty of the structure, but only addresses the portions of structure readily accessible and observable at the time of inspection. Our review does not constitute a design, nor is it all inclusive and the responsibility for the structural systems of the facility remains with the Structural Engineer of Record.
