Role:Construction Management and Inspection Services
UCM provided
construction management and inspection services for constructing a Class 2 landfill for geothermal waste. The site
is located in Imperial Valley in California.
UCM provided
design services for a 10,732 linear feet of 66-inch diameter tunnel,
2,938 linear feet of 84-inch diameter tunnel and 10,400 linear feet of
120-inch diameter tunnel. UCM prepared drawings, excavation volumes,
schedule, estimate for two tunneling methods such as jack and bore
versus EPB tunneling.
UCM provided
constructability review services for the Mission Valley East LRT project in San
Diego. This $440M project involves construction of a 5.8 mile extension of San
Diego's light rail transit system. The extension includes one mile of
underground LRT. Key features of the underground work are: 4000 feet of deep
cut-and-cover construction adjacent to critical infrastructure; an underground
station at San Diego State University; and a 1000-foot long, 40-foot wide by
40-foot tall tunnel section constructed using New Austrian Tunneling Method
(NATM). UCM also provided office engineering and inspection on this project. It
also includes the Assistant Resident Engineer for the NATM
Tunnel.
UCM provided design,
construction management and public
relations services for replacement of 22,000 linear feet of existing
sewer lines in a mature part of the City of Burlingame. Work includes
taking field measurements and incorporating design and technical
information into the plans
and specifications. The project utilized trenchless methods such as
pipebursting, cured in place pipe and horizontal boring. Conventional
method such as open trenching was also used. After the design phase,
UCM provided construction management and community relations including
developing and maintaining a project website for document control and
public information.
Project:Edenvale Sanitary Sewer Supplement Phase 5 Project
Location:San Jose,
California Client:HMH Engineers UCM
Role:Tunnel Design Support
UCM provided design services for a 56-inch diameter RCP sanitary sewer
utilizing microtunneling and jack and bore operations. Some portion of the alignment exhibit high groundwater levels which
prompted UCM to use microtunneling in installing the RCP.
UCM provided
construction management and inspection services for constructing an
80-inch diameter tunnel and installing a 66-inch inside diameter
reinforced concrete pipe utilizing microtunneling. The Contractor an
AKkerman 660 TBM which was used to excavate hard clay alluvium and
construction debris underneath Highway 101 in Burlingame, California.
Project:Balboa/Carmelita/Drake/Capuchino Easement Sewer Rehabilitation Project Project
Location:Burlingame,
California Client:City of Burlingame UCM
Role:Designer/Construction Management/Public Relations
UCM provided design,
construction management and public relations services for the City of
Burlingame for replacement of the existing sewer along the easements of
these four locations. Access is limited and sometimes difficult since
most of the sewer is behind properties. The project utilized trenchless
methods such as pipebursting, cured in place pipe and horizontal
boring. Conventional method such as open trenching was also used. After
the design phase, UCM provided construction management and community
relations including developing and maintaining a project website for
document control and public information.
UCM designed five crossings
of Mission and Islais Creeks in San Francisco in support of the 3rd Street
Light Rail Project, which will serve the area now under development as Mission
Bay. The two borings at Mission Creek are 580' long, 70 feet deep multiple
conduit pulls into a 36" borehole. The path for the two bores is within a
30' right-of-way with several existing and planned interferences (e.g., piles,
fill debris). The three borings at Islais are 850' long, 70' deep multiple
conduits, each within a 36" carrier casing (54"
borehole).

Role:Construction
Management/Consultant
UCM is providing
construction management services for the construction of a 10-foot diameter,
4,600 long sewer tunnel that is being excavated with a wheel type tunnel boring
machine that is planned for operation in open mode but can be switched to EPB
if required.
UCM designed and supervised
the sewer replacement for a developed portion of Burlingame utilizing pipe
bursting, lateral replacement and new manhole construction.
UCM provided horizontal
drilling and lateral installation pilot study for the Sonoma County Water
Agency. This project involves installation of 18" diameter perforated
casings using horizontal drilling. The purpose of the Pilot Study is to
evaluate whether such construction methods could enhance the water production
of Collector No.6 to more closely achieve the desired pumping rate of
approximately 20 million gallons of water per day.
Project:Thomas Shaft Chlorination Facility Project

Utilities Commission UCM
Role:Consultant/Resident
Engineer/Office Engineering
UCM provided on-site
management during construction of this chlorination facility. The facility
structure is C.I.P. concrete walls with composite steel concrete roofing system
and will house sodium hypo-chloride, utility water and waste liquid storage
tanks. The facility also includes two sampling and feed stations, transfer and
chemical feed pump rooms, instrumentation control and electrical room, and an
emergency backup generator system. Process instrumentation and control work
included installation of programmable logic controllers, communications and
workstations for local, remote and automated operation at the facilities. The
facility will be used to sample and treat the water of Hetch Hetchy's Coast
Range Tunnel-San Francisco's main water supply treatment.

Role:Construction
Manager
UCM provided construction
management services for the Bradshaw Sections 1 and 2 project which involved
installation of 120-inch reinforced concrete pipe beneath wetlands, Union
Pacific Rail Road tracks, and a major thoroughfare. Installation of the pipe
was completed by two pipejacking operations. One of 650 foot length was
completed with a 143-inch diameter Earth Pressure Balance TBM which allowed
tunneling through alluvial deposits which had a potential of encountering a
high ground water table. No-bell pipe with steel straps was jacked as the TBM
advanced. The second pipe jack was completed through dense silty sands with an
open faced digger shield.
