Stanford Height
Reservoir Seismic Upgrade Project
San Francisco, CA
In order to meet current seismic standards and to conform to all
State
Requirements Stanford Heights Reservoir was upgraded as part of
the Hetch
Hetchy improvements program, for the City and County of San Francisco.
The
upgrade included the improvement of water quality and the strengthening
of
the reservoirs structure. M Squared was contracted by SJ Amoroso
Company
to complete Civil, Structural, Mechanical and Corrosion Protection
work on the
project. Structural work included the construction of an inlet
vault structure
which required a 20ft deep excavation with a beam and lagging
shoring system,
new drainage around the reservoir and seismic bracing for the
outlet pipes in
the reservoir tunnels. Civil work included 2,800ft of 20
Ductile Iron Pipe on
Portola Drive, 400ft of 24 welded Steel Inlet Pipe to feed
the reservoir.
Mechanical work involved the installation of motorized actuators
for the
existing sluice gates inside the reservoir basins and vaults.
Corrosion
Protection work included the furnishing and installation of sacrificial
anodes,
conduits and conductors as part of the cathodic protection system
for both
the Ductile Iron piping and Steel Inlet piping.
300 Spear Street,
San Francisco, CA
Currently known as The Infinity,
300 Spear Street is two luxury condominium,
buildings located in downtown San Francisco, constructed by Webcor
Builders. M Squared Construction's portion of work included an
emergency
sewer system upgrade for the buildings. During the course of construction
it
was discovered that the existing sewer system did not have the
capacity to
facilitate the new buildings. M Squared Construction had to mobilize
within 48
hours and was given a very short timeframe in which to install
the new sewer.
This required working around the clock in order to meet the Owners
schedule.
Midway through our construction, we encountered ductbanks which
were in
direct conflict with the proposed design grade. M Squared immediately
proposed a new design to the City which included running two smaller
diameter pipes in lieu of the original design. This design was
accepted and we
were able to complete the project ahead of schedule.
Noe, Sanchez &
Ford Sewer Project
San Francisco, CA
M Squared Construction was the General Contractor for the San
Francisco
Department of Public Works project known as Noe, Sanchez, Ford
Sewer
Replacement. In total over 3,800 feet of sewer mains, ranging
from 12" to 24",
were replaced by open cut construction with a further 1,300 feet
ranging from
12" to 18", being rehabilitated using a method known as C.I.P.L.P
(Cured In
Place Liner Pipe). This process involves pulling a resin-saturated,
coated felt
tube into a damaged pipe. Hot water or steam is then used to cure
the resin and
form a tight-fitting, joint-less and corrosion-resistant replacement
pipe. Due to
the busy location, co-ordination was needed with several San Francisco
agencies, most notably the San Francisco M.U.N.I. to ensure that
no
inconvenience was encountered. In order to achieve this, weekend
work was
required, with M.U.N.I required to de-energize and isolate their
overhead lines.
Dublin San Ramon
Services District
Pleasanton, CA
M Squared Construction was awarded
a sub contract with Otto H Rosentreter
Company to install a co-generation facility at the Dublin San
Ramon Service
District (DSRSD) Waste Water Treatment Plant. The facility consisted
of two
300Kw fuel cells that are designed to run on anaerobic gases extracted
from the
Waste Water Treatment Plant. The 300Kw fuel cells are powered
by the gases
and create electricity which, in turn, is used to power the plants
Digesters.
These gases are also used to create hot water which is also supplied
to the
Digesters. M Squared Construction's portion of work involved the
installation
of the gas main, anaerobic gas piping, water main, hot water piping
and all
underground utilities necessary for the operation of the fuel
cells, as well as
stub outs for a future 300Kw fuel cell. It also included the construction
of the
reinforced concrete foundations for the fuel cell units as well
as the fuel cell
installation and hook ups.
