Authorize the City Manager to execute change orders in an amount not to exceed the total authorized contract. DISCUSSION The recommended action will allow the City to cover cost extras anticipated on Broadway north of 17th Street similar to those conditions encountered south of 17th Street. These cost extras are related to underground and pavement conditions on Broadway that were unforeseen. The Broadway Rehabilitation Project consists of upgrades and /or replacement of underground utilities, including the city's water main and water services, followed by street improvements including replacement of curb and gutter, removal and replacement of damaged sidewalks and curb ramps, and reconstruction of the pavement. The work limits on Broadway are between Civic Center Drive and Santa Clara Avenue. On August 5, 2013, the City Council awarded a contract to Christensen Brothers General Engineering, Inc., in the total amount of $4,733,144.65, which included a 10 percent contingency. While potholing the existing utilities in advance of installing the new water main along Broadway, unforeseen concrete pavement was encountered beneath the street, despite coring logs that showed cement treated base at certain locations. Staff also discovered that a sewer trench constructed in the late 1960's was not properly compacted, causing significant voids under the concrete pavement. Consequently, these unforeseen conditions resulted in necessary redesign and additional quantities of asphalt to pave the street. Contingency Increase Broadway Rehabilitation Project April 15, 2014 Page 2 The underground work on Broadway south of 17th Street is nearly completed, and the pavement conditions have been fully revealed. Staff is anticipating similar conditions north of 17th Street and staff therefore recommends making financial preparations to accommodate cost extras without delaying the construction activities. This is critical now that the project is in the second half of the construction phase. ENVIRONMENTAL IMPACT There is no environmental impact associated with this action. FISCAL IMPACT Funding for the increased construction contingency of $650,000 for the Broadway Rehabilitation and Water Main Improvements Project is available as follows: • $200,000 - Traffic Congestion Relief HUT Fund (Account 05917663- 66220) • $450,000 - Water Utility Capital Projects Fund (Account 0661'7647 - 66301). The Revised Cost Analysis (Exhibit 1) has been adjusted to reflect the total estimated project delivery cost of $5,813,430.65. Edwin "William" GaiVez, P.E.

The water main at STA 12 +75, 23 +00 and 30 +75 was redirected from the original alignment to avoid irremovable obstructions, including an electrical vault and gas line encasements. Also, various unforeseen obstructions were found and needed to be removed (PCO# 4,6,8,9,12,13,17,18,43 and 44). The Water Resources Department requested additional work not included in the original scope of work. This work included abandoning two valves at Parton Street, removing a 12" "TEE" connection at Van Ness Street and relocating several water services on the existing 12" cylinder main. (PCO# 5,16,19,20,34 and 41). The change order provides compensation for delays associated with production loss. A prior approval was granted on November 18, 2013. FINAL COST $101,405 Extra Work at Agreed Price 2. Prior to the start of construction on Broadway, the proposed traffic control plans were reviewed in conjunction with traffic flow and public convenience. To help Project No. 116743 and 1'. ;15 Request for Approval of Change Order No. 1 March 24, 2014 Page 2 of 3 mitigate potential conflicts, the contractor was directed to furnish and install 3 additional static signs, 2 changeable message signs, 2 speed feedback signs and 8 credit signs (project acknowledgement). These items were not part of the original bid. In addition, the project phasing was revised to minimize the impacts to business owners and residents. Field modifications were made to increase safety, including signage, striping and lane delineation. A prior approval was granted on January 6, 2014 (PCO# 1- 3,14- 15,29,50 and 52). AGREED PRICE $183,123 Extra Work at Agreed Unit Prices 3. While potholing the water main and services on Broadway, existing buried concrete pavement was encountered. The coring results indicated that cement treated base was present beneath the asphalt concrete pavement but once exposed, the material was more difficult to remove and required additional saw cutting or breaking prior to removal. The export of the spoils was hauled to a different plant for further processing and disposal. The proposed pavement structural section was revised to incorporate the existing buried concrete pavement in the center lanes. The buried concrete pavement in the outer lanes has to be removed to allow for construction of the water main and curb and gutter. These modifications will not sacrifice the integrity of the pavement, maintaining a design -life expectancy of at least 20 years.
