EHRA was selected as one of two firms to provide professional surveying services under contract to Houston Community College System.
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.
The facility features an activated sludge process system. Additionally, the facility is equipped with an emergency standby diesel generator.
This project was the second phase of parks implementation outlined in the District's Parks Master Plan, which was completed by EHRA in 2007. Utilizing the site of a recently demolished former wastewater treatment plant provided an opportunity to create a passive park space for District residents.
EHRA performed preliminary drainage area delineations for nine creek crossings and calculated approximate 100-year flows for each culvert crossing. Culvert structures were sized for each of the six crossings, ranging from 48” round pipe culverts up to dual 5’x5’ box culverts.
Throughout the past few years, 3D printing has become extremely popular within the civil engineering industry. Nonetheless, the ways items are being printed are changing daily with new discoveries.
Typically, a custom part is designed and then simply printed. However, only one material can be put into a printer at once. If multiple materials can be inserted at a time, manufacturers can better control heat properties, and environmental adaptation, etc. New research will help manufactures reduce the steps and decrease to only one machine that prints all of the designs. By having all materials inserted at once, there will be no need for adhesives. This will allow for designs to be ever stronger than they already are.
"Multimaterial additive manufacturing has opened the doors to so many different possible creations,” according to Science Daily. “It has allowed us to be bolder and be more creative. This allows us to vary the composition and add functionality to a product during 3D printing that is traditionally very difficult to achieve, and we can do this in a single process with a single machine.” said Bandyopadhyay, Endowed Chair Professor in the School of Mechanical and Materials Engineering.
