Walter,Public Works Director Manuel Guzman,Engineer I SUBJECT: lIIGUERA STREET PAVING PROJECT FROM M MORRO ST. TO NIPOMO ST.SPECIFICATION NO. 90684 CAO RECOMMENDATION 1. Award a contract to Granite Construction Company in the amount of$477,432 for the Higuera Street Paving Project from Monro St. to Nipomo St. Specification No. 90684. 2. Approve the transfer of an additional $66,623 from the Water.Distribution Master Account to complete the project funding for Fire Sprinkler Laterals. DISCUSSION On June 5, 2007, the City Council authorized the invitation of bids for the Higuera Street Paving Project from Morro to Nipomo St. Spec. No. 90684. Bids were open on July 5, 2007 and Granite Construction Company was the lowest bidder.. Bid Alternatives In addition to the basic project work to resurface Higuera Street between Mono and Nipomo including the installation of pedestrian lighting and curb ramp upgrades, the project was advertised with three Additive Alternates. The first, Alternate A, provided for new pavement at the intersection of Broad and Pacific Streets. This intersection was to be reconstructed with the installation of the traffic signal, but the signal project did not have adequate funds to complete that work. The intersection is rough and would benefit from some work, as the signal is likely to increase the pedestrian traffic volume. Alternate B involves the installation of conduit for a future service panel to be used by the Downtown Association (DA.) The DA has been interested in providing power for events and Thursday Night Market and agreed to pay for this portion of work. The last Alternative, C, added paving grid to the main rehabilitation project between Morro and Nipomo. Paving grid is intended to delay reflective cracking that results when Asphalt Concrete is placed over Cement Concrete, as is the case in our downtown. This project was approved with funding from the General Fund, the Sewer Fund, and two parts of the Water Fund, Water Distribution and the Fire Systems Improvements Fund. All bids received for this project were higher than the Engineer's Estimate; however, the low bid was less than the Engineer's Estimate for the General Fund, the Sewer Fund and the Water Distribution portion of the Water Fund. The work to install fire sprinkler laterals was significantly higher than estimated and is the reason the project as a whole is over the Engineer's Estimate. Staff is recommending awarding the Base Project, as well as Bid Additive Alternates A and B. The Downtown Association has committed to funding Bid Additive Alternate B. Bid Additive Higuera Street Paving Project Page 2 Alternate A will be funded by the General Fund. CONCURRENCES The Utilities Department concurs with moving forward with the Fire Sprinkler lateral work to prevent future damage to the pavement. The DA supports the installation of electrical conduit on their behalf. FISCAL IMPACT The 2005-07 Financial Plan, Appendix B, page 121 identifies $75,000 for the Higuera Street Paving Project. The 2006-07 Financial Plan Supplement identifies $30,000 for Street Lighting Conduit Project. The 2007-09 Capital Improvement Plan identifies $56,000 for Downtown Pedestrian Lighting and $125,000 in additional funding for the Higuera Street Paving work. At the time the City Council authorized the advertising of the project, $77,100 from the main street reconstruction budget was also authorized to be used. This would have reduced the funding available for street reconstruction next year. Based on the bids and the recommended award, the actual amount needed from the main street reconstruction budget will be reduced to$3,900, thereby reducing the impact to future year paving. Project Cost by Funding Source General Fund Water Sewer Fund Fire Total Fund Sprinklers Engineer's Estimate $323,500 $45,000 $10,000 $71,500 $450,000 Construction (Base Project) $280,066 $42,000 $4,000 $136,500 $462,566 Construction (Alt A) $9,777 $1,200 $500 $11,477 Construction (Alt B) $3,389 $3,3.89 Total Construction Costs: $293,232 $43,200 $4,500 $136,500 $477,432 Contingencies (10%) $29,000 $5,000 $1,000 $14,000 $49,000 Cultural Resources Monitoring $10,000 $10,000 Material Testing $1,750 $1,750 Printing $500 $500 Total Project Budget: $334,482 $48,200 $5,500 $150,500 $538,682 Funds Available: $363,100 $391,577 $635,243 $83,877 As noted in the table, the construction cost for the Sprinkler Reimbursement Fund portion of the project is higher than the current level of funding available. Staff recommends transferring $66,623 from the Water Distribution Master Account to fund the project. Higuera Street Paving Project Page 3 ALTERNATIVES 1. Do not award Alternate A—Paving at Broad and Pacific Not completing the reconstruction at the intersection of Broad and Pacific would reduce the project costs by about $10,000. Those funds could be applied to other streets in the downtown next year. The intersection would remain in poor condition. 2. Award Alternative C—Pavement Grid The cost to complete installation of the pavement grid is $75,000. At this time, staff is not recommending this additional expenditure. There are some benefits to installing pavement grid to reduce reflective cracking. However, the loss of$75,000 from next years paving budget and the real possibility that current redevelopment in the downtown will result in utility service cuts to the pavement in the next several years, convinced staff that the best approach is to use the $75,000 to complete additional paving in the downtown next year at another location.
