Huitt-Zollars is providing engineering and construction phase services for the Maintenance of Federally Assisted Channels. These flood control, navigational, and coastal protection facilities were originally constructed by the U.S. Army Corps of Engineers (USACE), Galveston District. Annually, as well as after significant rainfall events, Huitt-Zollars conducts an in-depth condition assessment inspection.
Huitt-Zollars prepared the construction documents for improvements to the 141-foot-wide Gated Structure at the Clear Lake Second Outlet. The gated structure and outlet channel were designed by U.S. Army Corps of Engineers. Improvements to the structure included new safety ladders; replacement of the gate screw-top stem covers with expandable covers; replacement of the gates’ sacrificial anode cathodic protection system; a new hoist system atop the structure; additional galvanized steel grating cat-walk atop the structure; gates and railing.
Huitt-Zollars provided preliminary and final design plans and construction documents for 15,000 LF of water and roadway improvements. The existing water main was removed and replaced for the entire length of roadway. Residential service lines to existing water meters were removed and replaced, connecting to the new water main. Huitt-Zollars distributed more than 300 public information flyers and conducted a public meeting to discuss the project with residents and field questions regarding the proposed improvements.
The project purpose involved eliminating cut-through traffic traveling to and from three significant destinations within an area of approximately 1.02 miles. The project improves motoring safety along the Southern Boulevard corridor between Juan Tabo and Eubank Boulevards by addressing speeding, illegal U-turns, heavy congestion during peak periods, and parking in the median. The project involved shifting the eastbound lane of Southern Boulevard north, reducing the median to 34 feet, and the addition of three signalized intersections. Depressing the medians provided curb openings that provi
Huitt-Zollars completed the design of a four-lane collector road which connects to two major arterials, Unser Boulevard and Westside Boulevard, and serves as entry for the new Presbyterian Hospital. The road right-of-way contains water, sewer, and storm drain piping sized to serve approximately 145 acres of commercial, office, and institutional land use, and to provide access to a proposed 1,000,000-SF Lifestyle Center.
Huitt-Zollars developed design and construction contract documents to widen approximately two miles of Thornton Parkway from the existing two lanes to a five-lane arterial. The project included preparation of construction contract and right-of-way acquisition documents and incorporated pavement rehabilitation/replacement, curb and gutter, sidewalk, retaining walls, storm sewer, utility improvements to relocate two water lines, two signalized intersections, and public involvement.
Huitt-Zollars provided civil engineering services for a portion of the City of Oklahoma City large scale downtown revitalization project. This extensive project involved replacement and reconstruction of underground water, sewer and drainage infrastructure, street replacement, construction of sidewalks, landscaping, and amenities. The scope of services included extending a 16-inch water main with utility, drainage and streetscape design, data collection, and surveying.
Huitt-Zollars prepared a preliminary engineering report and provided final design, bidding, and construction phase services for the reconstruction of 3,000 LF of Pech Road for the City of Houston. The project required replacing existing asphalt street and open ditches with a 41-foot reinforced concrete pavement with curb and gutter and the replacement of approximately 3,000 feet of sanitary sewer lines and waterlines. Other enhancement included bringing the sidewalks and driveways in the neighborhood up to the City’s standard.
Huitt-Zollars provided engineering design and construction phase services for two miles of street, drainage, and utility improvements near Montrose area, north of US 59. The project area consists of a mixture of single-family homes, multi-family apartments, and newly constructed town homes. The project scope included reconstruction of streets and sidewalks to current code, installation of wheelchair ramps, construction of new water and sanitary sewer lines, and improvements to the drainage system.
Huitt-Zollars provided studies of final geometrics resulting in additions of one through-lane in each direction on Oso Parkway, right-turn only lanes in each direction on Marguerite Parkway, and double left-turn lanes covering four directions at an existing arterial highway intersection. Raised medians on four legs of the intersection were reconfigured. Design constraints included access to existing developments, adjacent hillside slope buttress, major water pressure reducing station, utility vaults, and facilities.
