EHRA was selected by the client to provide engineering design and to serve as District Engineer for the 2,400 acre Towne Lake Development. Our survey department retraced the overall boundary and performed a topographic survey of the site.
Engineering design and construction phase services of water, sewer, drainage and paving for four subdivision sections and off-site channel (123 acres out of a 400 acre subdivision). There was 60-feet of elevation difference on this site and wooded lots were left in their natural state which required the installation of retaining walls.
The purpose of this project was to convert the existing at-grade crossing of Brazoria County Road 56 (CR 56) and State Highway 288 (SH 288) into a diamond interchange that includes a new overpass bridge. Coordination with TXDOT, area landowners, utility companies, and Brazoria County was integral in obtaining approval and acceptance of the project.
EHRA designed an expansion that implemented the installation of a new triplex lift station operating in conjunction with the existing duplex lift station.
The facility features an activated sludge process system. Additionally, the facility is equipped with an emergency standby diesel generator.
EHRA Construction Phase Services finished a 12-month review of construction prices for common civil infrastructure items. The results continue to show steady price increases for items where construction materials are in limited supply. Most recently, concrete products, which remained steady last year, are now showing notable price increases as well. We understand that the concrete price increase is both due to global cement supply challenges and local product shipping / delivery costs.
We have observed a steady trend of price increases for various water distribution items.
