LABEL
RECOMMENDED ACTION:
Recommendation
Adopt a resolution authorizing the Public Works Director to award and execute a construction contract with Granite Construction Company for the Main Street Streetscape Project (MS14RA03) in the bid amount of $1,292,265, authorizing the Public Works Director to approve contract amendments and charges for project services up to a total amount not to exceed $1,643,337, authorizing a budget appropriation in the amount of $464,337, and determining that the actions authorized by this resolution were adequately analyzed by a previous CEQA action.
Body
DISCUSSION:
In May 2012, City Council formally adopted the Downtown Napa Specific Plan, a planning document with recommendations, guidelines and strategies for proposed improvements within the Downtown Specific Plan Area aimed to enhance the Downtown Napa experience. Examples of the Downtown Specific Plan goals included activating the streetscape by promoting outdoor dining on sidewalks and cultivating a downtown that is welcoming and pedestrian friendly. The Downtown Specific Plan identified the need for streetscape improvement projects at several locations within the Downtown Specific Plan Area, including streetscape improvements to First Street (between School Street and Main Street), Main Street (between Second Street and Third Street) and the area recognized as the Brown Street Corridor (between Third Street and Pearl Street). While independent of the Downtown Specific Plan, Dwight Murray Plaza is also a project in the downtown area about which staff will be updating City Council at the second Council meeting in December.
The current project is the Main Street Streetscape Project (Project), located between Second and Third Streets, which will create an improved pedestrian environment and more opportunities for outdoor dining. The Project improvements include: widening the sidewalk on the west side of the street, a raised pedestrian scramble intersection at Main and Second Street, an at-grade loading zone along Main Street, as well as standard downtown streetscape amenities of street trees with tree grates, ornamental lighting, bollards, bicycle racks and trash receptacles.
The Project scope of work generally includes new sidewalk construction, road grading and paving, installation of new storm drainage infrastructure, construction of an ADA ramp, installation of truncated domes and bollards, road striping, signage, traffic signal installation, lighting installation, electrical work, tree planting, placement of colored and textured HMA, abandoning a monitoring well, survey monumentation re-establishment and utility adjustments and utility agency coordination.
The engineer’s estimate of probable construction cost for the Project was $1,400,000.
Staff publicly bid the Project and on October 30, 2018, four (4) formal bids for construction were received. The bids were as follows:
$1,292,265.00 Granite Construction Company Ukiah, CA*
$1,322,957.75 Ghilotti Bros., Inc., San Rafael, CA
$1,432,121.00 Ray’s Electric, Oakland, CA
$1,506,530.00 Lister Construction, Inc., Vacaville, CA**
*Apparent Lowest and Best Bid
**Includes mathematical correction to bid schedule total (submitted as $1,507,760.00)
The construction budget is proposed as follows:
Lowest and Best Bid Amount $1,292,265
Contingency for unforeseen conditions (12% of bid) $ 155,072
Construction Management and Inspection $ 105,000
Public Works Engineering Staff $ 61,000
Materials Testing (Consultant) $ 30,000
Estimated Total $1,643,337
The contingency, construction management and inspection costs, public works engineering staff and material testing are each an estimate. The funds can be used interchangeably between the items listed above.
Note, the contingency for this project is set higher, 12% rather than a typical 5% to 10% to account for unforeseen conditions under the sidewalk and street section, i.e., buried man-made objects, etc. This is based on recent experience with the Downtown Restroom and First Street Streetscape projects and is an inherent risk when constructing along a corridor such as Main Street which has been serving as a street for more than a century.
FINANCIAL IMPACTS:
The existing Project budget is insufficient to cover the construction budget estimate. To meet the time critical schedule of the Main Street Project, staff proposes funds be appropriated from the Trower Avenue Storm Drain Improvements Phase II Project. That project currently has a balance of $1,034,635 in the project budget.
While important, the Trower Storm Drain Phase II project needs to be reconfigured such that the design and construction are of a size and scale that can be delivered in a logical phased approach, in-line with the available funding.
The remaining funds for the Trower Avenue Storm Drain Improvements Project could be used for the design work and supplemented during the next capital improvement project budget cycle prior to needing the full funding amount for construction.
To move forward with the Main Street Streetscape Project, an amount of $464,337 is requested to be appropriated from the existing Trower Avenue Storm Drain Improvements (SD17PW03). This gives the Main Street Streetscape a total project budget of $1,643,337.
