other obstacles. Right-of-way requirements were determined and legal descriptions
and plats prepared.
Plan and profile drawings were plotted directly from field notes using
an IBM computer with AutoCAD software. Design calculations were run for
steel, ductile iron and steel cylinder concrete pressure pipe. When required,
thrust was controlled by designing thrust blocking and restrained joints.
Effects of surge were analyzed to determine the need for additional surge
protection in the system.
The project included large fittings and 48" valves. The spacing of
the valves and outlets was studied. Corrosion control was designed for
the ductile iron and steel pipe alternatives.
At one end, the line was connected to an existing 60" line. At the
other end, coordination was made with another A/E who was designing an
adjacent project.
The firm provided a resident project representative. Other services included
cost estimates, bidding assistance, shop drawing review, pay estimate
review, periodic inspection, final inspection and as-built drawings.
Project List
As part of a major water expansion project, the firm was retained by
the City of Tulsa to design and inspect two miles of 48" water main.
Detailed field surveys were made to establish vertical and horizontal
control. All obstructions were located. The firm was responsible for recommending
the most feasible route and alignment considering the location of existing
utilities and other obstacles. Right-of-way requirements were determined
and legal descriptions and plats prepared.
Photogrammetry was used for the plan view and to determine the centerline
profile of the ground at the pipe location. Design calculations were run
for steel, ductile iron and steel cylinder concrete pressure pipe. Where
required, thrust was controlled by designing thrust blocking and restrained
joints.
The project included large fittings, 24" butterfly valves and 30"
ball valves in structural concrete vaults. Corrosion control was designed
for the ductile iron and steel pipe alternatives. A design for the connection
to existing facilities was done for one end of the project. The other
end was designed to allow future connections without interruption of water
service.
The firm was responsible for resident inspection. Other services included
detailed cost estimate, assistance during bidding, shop drawing review,
contractor's pay estimate review and as-built drawings.
Project List
The firm was retained to provide plans and specifications for a 300 G.P.M.
water booster pump station and 50,000 gallon above ground water storage
tank. The pumps were to provide needed pressure to the water distribution
system northwest of the City.
Site survey was done by in-house field crew using electronic "Total
Station" equipment. Data was transferred directly to the firm's CADD
system, AutoCAD, for preparation of the topography plan.
The design called for an above ground duplex pump station, skid mounted,
inside a concrete masonry unit structure. The structure was detailed by
the firm's in-house architectural staff.
