Facilities requiring expansion were also common wall construction, and the EHRA team converted the facilities into aerobic digesters and sludge thickeners.
EHRA designed an expansion that implemented the installation of a new triplex lift station operating in conjunction with the existing duplex lift station.
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.
EHRA worked with the District to create a comprehensive Parks Master Plan, which included recommendations for the development of over two miles of hike/bike trails adjacent to local streets, and within flood control and utility pipeline easements. The District began implementation of the Plan by prioritizing the beautification of West Road, a major arterial street that runs through the District.
Identified as a top priority during the development of the District’s Parks Master Plan, this portion of trail was the first phase of over two miles of planned trails to provide connectivity and recreation for District residents.
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.
