DISCUSSION
The City of Merced utilizes groundwater as the sole source for the City’s water supply system. The water system must be expanded to accommodate growth as detailed in the Merced Vision 2030 General Plan. The City Engineer and Public Works Director have recommended that a water well be located on the southeast boundary of the City at the intersection of Tyler Road and Mission Avenue. This proposed municipal Well No. 20 site location would serve to stabilize pressure in the water distribution system and avoid service disruptions while other City wells are off-line for maintenance. The new well also serves as a replacement for Well No. 6 that was removed from service in 2014.
On January 10, 2014, the Council awarded the well design services contract to Luhdorff and Scalmanini Consulting Engineers, Inc. (Luhdorff and Scalmanini). They advanced a test borehole and obtained soil and groundwater samples from the site in March 2014. Luhdorff and Scalmanini recommended that the City proceed to install the production well at this location and staff concurred with their endorsement.
The project generally consists of: the installation of a pump station building, electrical service, emergency backup generator, and associated plumbing to connect the site to existing water piping. The project design also includes a storm water retention basin and plumbing to discharge excess water to the adjacent Merced Irrigation District’s Hartley Slough canal.
Luhdorff and Scalmanini, under the direction of City staff, prepared plans and specifications for the work. The project was advertised and the bids were opened on July 25, 2019, with the following results:
1. Clark Bros., Inc. (Dos Palos*) $3,560,215
2. W.M. Lyles Co. (Fresno) $3,876,100
3. Sierra Comm. and Const., Inc. (Catheys Valley) $4,512,000
4. Syblon Reid (Folsom) $4,587,700
5. Myers and Sons Construction, LLC (Sacramento) $5,476,500
(* fixed office in Merced County and active City of Merced business license qualifies contractor as a certified Local Business Enterprise)
The engineers estimate was $3,300,000.
