Stiver Engineering provided a wide array of land development services for a contractor’s headquarters and operations yard on Luthe Road in Houston, Texas. Our work included plans for drainage, grading, landscaping, paving, stormwater pollution prevention, traffic control, and aggregate storage. We also created designs for a truck washout, drilled shaft foundations for concrete batch plant storage tanks and a steel canopy building structure, a hopper ramp with spread footings and a hopper slab foundation with drilled shafts.

As part of a levee improvement project in Sugar Land, Texas, Stiver Engineering provided analysis and design for a three-sided shoring system with steel frames and timber lagging. The shoring was roughly 28.5 feet deep and set back in the levee with one side of the shoring system daylighting into the channel.

The Mill Creek Drainage Relief Tunnel is a construction project that will bring needed infrastructure improvement to east Dallas, Texas. It will include 26,385 linear feet of tunneling at a 30-foot finished diameter with eight intake shafts and six lateral tunnels excavated by roadheader or excavators/breakers. The tunnel is being driven through Austin chalk by a Main Beam Robbins tunnel boring machine (TBM).

Stiver Engineering provided construction consulting services for the contractor prior to and during the tunnel construction. Our services included several trench safety plan designs, a sound wall design using steel soldier piles and acoustic panels, and a removable shaft cover and rigging details for several liner plate shafts. We also created a design for attaching the access cage ladder and landings on the ring beams of the liner plate shaft and on the vertical rock face. Other work included traffic control plans and designs for shoring, concrete collars, steel bulkheads, supporting existing utility lines, and a starter tunnel/gripper wall for the TBM.

The tunnel, which stretches from the State-Thomas District in Uptown Dallas, through Mill Creek and Peaks Branch, will be constructed mostly underground with little impact to neighborhoods. Once complete, the approximately 5-mile-long tunnel will sit 70 to 100 feet below ground to provide flood relief.

The Mill Creek Drainage Relief Tunnel is a five-mile underground tunnel that will provide 100- year flood protection for nearly 6,000 commercial and residential properties in the east Dallas area, including Baylor Medical Center. The current drainage system in these areas was constructed 50 to 70 years ago, and only provides a two- to five-year flood protection. Major flooding that occurred in 1995, 2003, 2006 and 2009 crippled these areas and showed dire need for the construction of this drainage relief tunnel. The Mill Creek/Peaks Branch/State-Thomas Drainage Relief Tunnel will improve stormwater management resulting in saved lives, protection of schools, medical facilities, residents and streets. Prior to construction beginning, a TBM will be constructed on site. By using a TBM, there will be minimal utility relocation, as well as minimal street and traffic impacts. Once complete, the tunnel will be approximately 30 feet in diameter, and will be designed to carry a maximum flow of nine million gallons per minute. This provides exponential relief of flooding during large rain events. The tunnel will have six intake sites along the alignment. These include:

  • Woodall Rodgers Intake – Intersection of Woodall Rodgers Freeway and Maple-Routh Connection
  • Mill Creek Intake – Intersection of San Jacinto Street and Apple Street
  • Peaks Branch Intake – Intersection of North Carroll Avenue and Victor Street
  • Peaks Branch 2 Intake – Intersection of E R L Thornton Freeway (I-30) and South Hill Avenue
  • East Peaks Branch Intake – Intersection of Bank Street and Herndon Drive
  • Outfall – White Rock Creek at Barber Avenue

 

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.
