The Chelford City Diversion project will consolidate and upgrade public works facilities in part of Houston through the installation of sanitary sewer lines, manholes, reinforced concrete pavement, and curbs. As part of the project, Stiver Engineering redesigned a concrete vault at the junction of a 60-inch sanitary sewer pipe and a 108-inch sanitary sewer pipe. The bottom of the 22-foot-tall concrete vault was 70 feet below the existing ground.

Using Danby liner and grout, Stiver Engineering provided a pipe rehabilitation design for a 93-inch arch pipe at a wastewater treatment plant in Cincinnati, Ohio. The existing pipe section along with the Danby liner and grout allowed us to create a composite section. The composite section was designed so the contractor could provide a clear span over existing utilities. Stiver also designed bulkheads inside the existing 93-inch arch pipe to provide access for the pipe’s rehabilitation.

Emmons Motor Co. is a Houston area automotive dealership that has been operating in Houston, Texas since 1972.  The used car dealership relocated to 16 acres at Interstate 45 and Farm to Market Road 528 in the Clear Lake area.  The total cost of the project is estimated at $15 million and was completed in November 2017.

The new 48,000-square-foot dealership holds roughly 450 cars on-site, up from Emmons’ previous Pasadena location that handled 350 cars. The new dealership also includes a state-of-the-art body shop, a waiting area and an 18,000-square-foot showroom.

Stiver Engineering provided the civil engineering site development services for the Emmons Project.

The Bergamos Spa Retreat is a $6.5 million, 22,000-square-foot day spa and is the largest freestanding day spa in Texas.  It is owned by Marylyn Reed, the great-granddaughter of the late beauty and skincare mogul Mary Kay Ash.  The spa was completely renovated after the facility was destroyed by Hurricane Harvey in 2017.

Stiver Engineering provided the site civil engineering design for the redevelopment of the site after Hurricane damaged the old facilities in 2017.

 

The DigIndy Project is a nearly 28-mile long network of 18 foot diameter deep rock tunnels being built 250-feet beneath the city.  Beginning near the Indiana State Fairgrounds on the north, and ending on the south side of Indianapolis, DigIndy will be the largest public works project in the city’s history.

The tunnel system will extend along Fall Creek, White River, Pogues Run, Pleasant Run and Bean Creek to create a collective, underground storage and transport facility for wastewater.  All sewage stored and transported in the tunnel system is sewage that otherwise could have gone directly into local waterways. The tunnel system is a component of the federally-mandated plan to reduce raw sewage overflows into the waterways.

The Indianapolis Deep Rock Tunnel Connector Pump Station Project included a screening and grit removal system consisting of 180 feet of 6 foot diameter connector tunnel, a subterranean pump room that is 60 feet wide by 98 feet long by 66 feet tall, a 44 foot diameter main access shaft with an enclosed elevator, enclosed stairway and various utility systems.  The subterranean pump room is located 250 feet below ground surface.  The project also includes a 23 foot diameter equipment shaft with embedded electrical conduits, an at grade pump station building, an at grade main access shaft building, an at grade discharge chamber and miscellaneous site work.

Stiver Engineering was retained for construction consulting by the contractor to design thrust blocks and pipe supports for the intake piping, miscellaneous piping running up the 250 foot access shaft walls and piping for the discharge chamber.  Stiver Engineering designed the permanent dewatering system for the large subterranean pump room 250 feet below the surface.  We also assisted in the design of a mobile concrete forming system for the construction of the 6 foot diameter connector tunnel.
