Discussion
Water main construction projects require full time inspections and construction
management services to administer the contract. The annual water main project entails
work both during the day and at night. There is a need to hire a consultant to
supplement and aid the City with full time daily and nightly inspections for this project.
Construction management services include: conduct weekly progress meetings;
coordination between inspector, designer, and contractor; record management and
document control; review and process requests for information; and interpretation of
contract documents, submittals, contract schedule, change order proposals,
maintenance of field logs, as -built verification, and labor compliance. The role of an
inspector entails quality control, observing excavations, traffic control, daily reports,
water outages, public outreach and coordination of construction activities.
The proposed Water Main Replacement project consists of three segments as outlined
below.
Segment 1 would construct approximately 2,000 linear feet of new 12 -inch diameter
water main along Olympic Boulevard between 26th Street and Stewart Avenue. The
new water main would complete a loop, improving pressure along the segment and
would provide five new fire hydrants along the future EXPO Light Rail Bergamot Station
as part of the agreement with Los Angeles County Metropolitan Transit Authority.
Segment 2 would replace old cast iron water mains and construct approximately 8,300
linear feet of new Polyvinyl chloride (PVC) type water mains; replace and construct new
valves; and renew residential and commercial water meters. Pipelines in Project 2 were
installed in the 1920's and the 1940's are reaching the end of their 100 -year useful
lifespan. Segement 2 includes the following locations:
• Olympic Boulevard from 12th Court to Lincoln Boulevard
• Lincoln Court from Olympic Boulevard to Colorado Avenue
• Olympic Boulevard (north side) from 17th Street to 19th Street
• Olympic Boulevard (south side) from 17th Street to 20th Street
2
® 17th Court from Olympic Boulevard to 1 -10 Freeway
® 18th Court from Olympic Boulevard to 1 -10 Freeway
® Pennsylvania Avenue from 20th Street to 22nd Street
® Euclid Court from California Avenue to Wilshire Boulevard
® 16th Court from Broadway to Santa Monica Boulevard
® 20th Court from Wilshire Boulevard to Arizona Avenue
® Ocean Avenue from California Avenue to Wilshire Boulevard (southbound
parking lane)
Segment 3 would relocate approximately 1,200 linear feet of treated urban runoff water
main and 200 feet of water main to facilitate the tight construction schedule for the
future Colorado Esplanade project.
Construction Schedule
Construction work began September 2, 2014 and completion is estimated by February
2015.
Construction Management Selection
In May 2014, the City requested Statements of Qualifications for construction
management and inspection services for upcoming construction projects throughout the
City. The request for Statements of Qualifications was advertised on the City's online
bidding website. Fifteen firms submitted Statements of Qualifications for this project
which were reviewed and rated by Public Works staff. Selection criteria included
technical competence, staffing capability, project approach, past performance, dispute
resolution, quality control, cost control, management services, customer service and the
ability to meet required time frames. The top firms were invited to interview with Public
Works staff in July 2014: GK & Associates, SA Associates, and Willdan Engineering.
SA Associates is recommended as the best firm to provide construction management
and inspection services based on their competitive prices and their direct experience
working on water main projects for the City of Santa Monica. Services provided by SA
Associates would include construction management, and continuous inspection of the
3
contractor's work. Staff contacted reference agencies and all respondents reported that
SA Associates provided exceptional construction management and inspection services.
