City of Culver City, California Agenda Item Report RECOMMENDATION: Staff recommends that the City Council (1) approve the final plans and specifications and authorize the advertisement for bids and (2) approve an amendment to the existing professional services agreement with Willdan for engineering design services for the Sepulveda Boulevard Widening Project (Playa Street /Jefferson Boulevard intersection to Green Valley Circle), P-881. BACKGROUND: The Sepulveda Boulevard corridor is a principal arterial in the City. Currently, within the project limits, there are three (3) travel lanes northbound and two (2) travel lanes southbound between Playa Street/Jefferson Boulevard and Green Valley Circle. This project will provide for three (3) continuous lanes in the southbound direction. The proposed work will include street widening and roadway reconstruction, landscape median modification, traffic signal modification, disability accessibility improvements, utility relocation and other miscellaneous improvements. As part of this project, Sepulveda Boulevard southbound from Berryman Avenue to Playa Street/Jefferson Boulevard will be re-striped and on-street parking eliminated to add a third southbound lane within the existing street width. In addition, during construction afternoon period peak hour parking restrictions (between 3pm and 7pm) will be in effect on southbound Sepulveda Boulevard between Sawtelle Boulevard and Berryman Avenue. This will allow for the third southbound lane to be extended north to Sawtelle during the peak afternoon traffic period thus providing additional Meeting Date: 02/07/2011 Item Number: C-5 CITY COUNCIL AGENDA ITEM: 1) Approval of Final Plans and Specifications and Authorization to Advertise Bids for the Sepulveda Boulevard Widening Project (Green Valley Circle to Playa Street /Jefferson Boulevard), P-881; and 2) Approval of an Amendment to the Existing Professional Services Agreement with Willdan for Engineering Design Services Contact Person/Dept.: Hong Wang/PW Phone Number: 310-253-5604 Fiscal Impact: Yes [X] No [] General Fund: Yes [] No [X] Public Hearing: [] Action Item: [] Attachments: [X] Commission Action Required: Yes [] No [X] Date: ________________ Public Notification: (E-Mail) Agenda and Meetings – City Council (02/02/11); Willdan Engineering (02/02/11) Department Approval: Charles D.

In June 2007, the City successfully secured a competitive grant of $3,982,000 through Metro’s 2007 Call for Projects for this widening project. In June 2008, the City Council approved a professional services agreement with Willdan Engineering for preparation of final construction plans and specifications for this project with a not-to-exceed fee amount of $409,985. DISCUSSION: Throughout the design process, staff frequently met with Southern California Edison (SCE) to coordinate the relocation of several transmission power poles along Sepulveda Boulevard, between Slauson Avenue and Westfield Culver City’s new driveway, which is where physical street widening is required. In addition to widening the street section by relocating the curbline, the third southbound through lane addition will be made possible by median modifications and lane width adjustments. Several iterations of preliminary design plans were prepared in order to evaluate all feasible widening alternatives and SCE relocation options. Staff also explored the cost of undergrounding the transmission power line and found it to be cost prohibitive (approximately $3,300,000). Therefore, staff chose to widen the eastside of Sepulveda Boulevard between State Route 90 and Slauson Avenue, and SCE will relocate four transmission poles, at its cost, in accordance with the utility franchise agreement with the City. It is anticipated that SCE will be relocating its power poles concurrently with the street widening and reconstruction project. Staff has been working with the City of Los Angeles, the County of Los Angeles, and Caltrans for encroachment permits and is in the final stages of the approval process. Portions of the project are within these agencies’ jurisdictions. Willdan’s original scope of services included design services for widening the west side of Sepulveda Boulevard. Due to the prolonged coordination process and cost of relocation or undergrounding the existing SCE overhead facilities on the west side of Sepulveda, as previously stated, staff determined that widening the street on the east side was a better, more cost effective alternative. This design change, coupled with an extended period of SCE design coordination, along with other city initiated extra design services and permitting agencies required studies/changes, resulted in Willdan providing additional design services, which could not have been foreseen (see attached letter detailing the extra design work), before the professional services agreement was executed with them. Staff reviewed Willdan’s request and found it to be fair and reasonable and is therefore recommending a second contract City of Culver City, California Agenda Item Report amendment (in the amount of $93,650) be approved by the City Council. A first contract amendment in the amount of $39,400 was previously approved administratively as it fell under City Council pre-authorized contingency amount for additional services. Willdan has successfully completed the final construction plans and specifications for bidding. Stage Construction and Traffic Management: Due to the Portland Cement Concrete curing time for a durable pavement service life, the project will be constructed in phases in order to maintain as many open traffic lanes as possible during street reconstruction. Changeable Message Signs will be placed at strategic locations to inform the public of the on-going construction activities. Alternate routes will be designated by signage. In order to expedite the construction and thus minimize the overall inconvenience to the public, it is recommended that construction be allowed between 6 am and 10 pm, seven days a week. The contract documents require that the work be completed in 100 working days, (approximately 5 months). The anticipated start of construction is May 2011 with completion in October 2011. A community meeting to discuss construction impact has been scheduled for 7 pm on February 22, 2011 at City Hall. A meeting notice will be sent to all Sunkist Park neighborhood residents, residents south of Sawtelle Boulevard between Sepulveda Boulevard and Overland Avenue, and businesses adjacent to the project. Construction management services will be procured through a Request for Proposal process. The recommendation for award of this contract will be provided to the City Council at the same time the construction contract award recommendation is presented. Final construction plans and specifications will be made available for public inspection at the City Clerk’s Office upon approval by the City Council. FISCAL ANALYSIS: The estimated total construction cost is $6,700,000, including construction, contingency, construction management, inspection, and material testing. The project is funded with $3,982,000 of LA County Proposition C (0.5% countywide sale taxes) grants and $2,718,000 of West LA College Mitigation Funds, for a grand total budget of $6,700,000.

Culver City Boundary I 2, you w ILLDAN externding vv e , Engineering reach January 24, 2011 Mr. Hong Wang, PE Senior Civil Engineer City of Culver City Public Works Department 9770 Culver Boulevard Culver City, CA 90232 Subject: Sepulveda Boulevard Improvements Project Additional Design Services Dear Mr. Wang: Willdan Engineering (VVilldan) is pleased to provide the City of Culver City with a proposal for an additional scope of services for the Sepulveda Boulevard Improvement Project. As you know, over the past several months, there have been unforeseen developments with the project, primarily due to relocation issues involving Southern California Edison (SCE), but also involving other mailers and various decisions by the City of Culver City. This letter is our request for additional compensation for the additional scope of services which arose during development of the project design. The items of additional work are outlined below: SEPULVEDA BOULEVARD - EAST SIDE vs. WEST SIDE WIDENING Our original scope of work included design services for widening the west side of Sepulveda Boulevard, work which was successfully performed by Willdart However, due to the proposed relocation/undergrounding of the existing SCE overhead facilities on Sepulveda Boulevard, the City determined that it needed to perform the street widening on the east side instead of the west side. This resulted in Willdan providing additional design services. Following are the major design change items: 1. Civil improvement plan modifications. 2. PCC joint layout redesign. 3. Signing and striping plan modifications. 4. Traffic signal plan modifications. 5. Street lighting plan modifications. 6. Traffic control plan modifications due to FCC pavement joint shifting. 7. Landscape improvement plan modifications.

Winder] was requested by the City to provide the following additional services: 1. Prepare legal description for the 4 foot right-of-way dedication. 2. Provide design survey along the new right-of-way. 3. Revise project plans and specifications to include proposed street improvements within and adjacent to the new right-of-way. MISCELLANEOUS LANDSCAPE ARCHITECTURE SERVICES The following additional Landscape Architectural services are outside of Willdan's original scope of services: 1. Include median islands on Jefferson Boulevard west of Sepulveda Boulevard for landscape and irrigation modifications. Replace tree grate detail with City preferred model. 3. Replace street tree palette with updated City master plan preference. 4. Include landscape and irrigation modification notes on plan for medians R&R on Slauson Avenue at Sepulveda Boulevard. 5. Include landscape and irrigation modification notes on plan for medians R&R at Jefferson Boulevard/Playa Street. 6. Include California AB 1881 water conservation worksheets. 7. Provide street tree R&R notation on plans for trees within Jefferson Boulevard/ Playa Street and Sawtelle Boulevard. MISCELLANEOUS TRAFFIC ENGINEERING SERVICES The following additional Traffic Engineering services are outside of Willdan's original scope of services: 1. Review Red Flex Design plans for relocation of camera equipment 3 January 24, 2011 Page 3 2. Additional work requested by Ca'trans for Permit: a. Modify and submit to Caltrans street lighting plan (per City) to relocate street light to on-ramp. b. Prepare traffic counts for the SR90 on-ramp and Fox Hills Mall, driveway southbound U-turns. c. Prepare detour plan for closure of SR90 on-ramp during construction. ADDITIONAL ITEMS NOT INCLUDED IN ORIGINAL SCOPE OF WORK 1. Revised plans to include the Fox Mall development project improvements in as- built condition. This included the collection of additional survey after construction had been completed to obtain the grades of the curbs, flowlines, and new concrete pavement, in order to properly design the pavement in this area 2. Additional decorative crosswalks at Playa/Jefferson, Slauson, and Green Valley intersections. 3. Additional project management services for all additional design services. 4. Extended project completion date resulted in VVilldan's loss of production and loss of efficiency in preparation of the project plans, specifications, and estimates (PS&E). As you are aware, Willdan started providing design engineering services on the Sepulveda Boulevard Widening Project in June 23, 2008, with an anticipated project completion date in March 2009. Wil!den is still in the process of finalizing the project PS&E, with an anticipated completion date in February 2011. The extension of the project completion date has been primarily due to relocation issues involving Southern California Edison (SCE), Fox Mall, and other matters and various decisions by the City of Culver City. The loss of production and loss of efficiency has arisen in a number of ways from a number of factors: a. Multiple starts and stops in the project work flow caused extra effort and time being expended to re-establish the project documentation in an orderly manner to move forward in the new direction based on changes since the last stop of work. b. Extra time was spent for personnel to orientate themselves to the applicable issues through review of existing plans, documents, estimates, and get to a complete perspective on the status of the project. c. Reinitiation of the work often involved lengthy additional communications and meetings between WiMan staff and City personnel to discuss project requirements and reach agreement on the precise plan for moving forward.
