Wray, Deputy Director of Development Services/City Engineer By: Kevin Merrill, Principal Civil Engineer SUBJECT: ACCEPT ALL WORK PERFORMED BY CALIFORNIA PROFESSIONAL ENGINEERS, INC. FOR THE SANTA ANITA AVENUE CORRIDOR TRAFFIC SIGNAL AND CROSSWALK IMPROVEMENTS, AT THE INTERSECTIONS OF SANTA ANITA AVENUE AND ALTA STREET, AND SANTA ANITA AVENUE AND LE ROY AVENUE, AS COMPLETE Recommendation: Approve SUMMARY On August 20, 2019, the City Council awarded a contract to California Professional Engineers, Inc. (“CPE”), in the amount of $713,791, plus a 10% contingency, for traffic signalization and crosswalk modifications at the intersections of Santa Anita Avenue and Alta Street, and Santa Anita Avenue and Le Roy Avenue. There were four (4) change orders on the project totaling $61,925.75, or 8.68% of the original contract amount. With the adjustment for change orders and actual quantities, the final contract amount is $775,716.75, which is within the total appropriated budget. The terms and conditions of this project have been complied with, and the required work has been performed to staff’s satisfaction. It is recommended that the City Council accept the project as complete and authorize the final payment in accordance with the contract documents. BACKGROUND This project proposed the installation of new traffic signals at the intersections of Santa Anita Avenue and Alta Street, and Santa Anita Avenue and Le Roy Avenue. The project included crosswalk modifications, sidewalk and ADA accessible ramp construction, and the removal of flashing warning light systems at both intersections. Traffic Signalization at Santa Anita Avenue/Alta Street and Santa Anita Avenue/Le Roy Avenue December 1, 2020 Page 2 of 4 The plans and specifications were originally completed in late 2018. However, there were coordination issues with the County of Los Angeles over work on County Park property at the Alta Street intersection, and with Southern California Edison (“SCE”) over street light conflicts. Those issues were resolved, and the plans and specifications were completed in June 2019. The project was advertised for bids in July 2019, and on August 20, 2019, the City Council awarded a contract to CPE, in the amount of $713,791, plus a 10% contingency. DISCUSSION The construction began in February 2020 and was ultimately completed in October 2020. The project was delayed several months due to a long equipment delivery time period, COVID-19 related staffing and scheduling issues, a conflict with the County over the need for an easement on park property, the wait for SCE to temporarily secure a nearby street light, and the wait for SCE to finalize their design and schedule crews to provide power to the new traffic signals. The project is now completed to the City’s satisfaction. There were four (4) change orders on the project, totaling $61,925.75, or 8.68% of the original contract amount. They are as follows: • The first change order was for the purchase and installation of four (4) small mast arms and reflective street name signs at the two new signalized intersections. These were inadvertently left off the plans but are important and necessary for street name identification. The change order also included a modified signal pole foundation adjacent to the County Park property at Alta Street. The original design called for the signal pole to be installed on County property. Prior to plan approval, the plans were sent to the County for their review and, although they had some issues with the City’s proposal, they ultimately approved the plans. However, just before the pole was to be installed, the County decided that the City needed to purchase an easement, with an estimated delay of several weeks to appraise the land, prepare the documents, and work through the County’s review and approval process. Upon further review of the situation, it was determined that the pole could be moved to the public right-of-way but would require a customized foundation. Although this alternative cost the City in additional foundation work, it saved the City a considerable amount of time and effort, the costs of easement document preparation and purchase, and potentially the cost of additional County mitigation measures. • The second change order was for the additional cost of a dual meter pedestal instead of a single meter pedestal, as originally designed, at the Santa Anita Avenue and Le Roy Avenue intersection. This was an SCE requirement that was required after the project was bid, due to SCE’s delay in reviewing and commenting on the plans in a timely manner. Traffic Signalization at Santa Anita Avenue/Alta Street and Santa Anita Avenue/Le Roy Avenue December 1, 2020 Page 3 of 4 • The third change order was for the modifications to the sidewalk and curb ramp located on the northeast corner of Santa Anita Avenue and Alta Street, and some other minor ramp modifications. The Santa Anita Avenue and Alta Street ramp modification was extensive due to the existing right-of-way limitations and obstacles, and vertical differences that were too great to comply with ADA. This required expanding the ramp limits to accommodate a unique ramp design. • The fourth change order was for the additional mobilization of the striping sub- contractor to paint the striping at the Santa Anita Avenue and Alta Street intersection due to the delay in the northeast corner curb ramp construction in the third change order. A summary of the change order costs is as follows: Original Contract: $713,791.00 CO #1 $23,342.16 CO #2 $766.59 CO #3 $35,696.00 CO #4 $2,121.00 COs Sub Total: $61,925.75 Final Total Contract: $775,716.75 The four change orders totaled $61,925.75, bringing the final construction total to $775,716.75, which is within the approved 10% contingency. FISCAL IMPACT The traffic signalization and crosswalk modifications were budgeted in the Fiscal Year 2016-17 Capital Improvement Program at $700,000, with $560,000 in special grant funding, and $140,000 in Transportation Impact Funds. Prior to the contract award, approximately $110,000 had been spent on engineering design and staff time, leaving a balance of $590,000. At the time of contract award, the City Council approved an additional appropriation of $196,000 from the Transportation Impact Fund to cover the construction contract plus the contingency as follows: Original Contract $713,791.00 Change Orders $ 61,925.75 TOTAL $775,716.75 Available Budget Additional Appropriation $590,000.00 $196,000.00 TOTAL $786,000.00 There are sufficient funds to cover the expenditures.
