EHRA conducted a traffic engineering study to identify the impacts of a proposed master development located near the intersection of FM 1488 and Peoples Road in the City of Conroe.
Facilities requiring expansion were also common wall construction, and the EHRA team converted the facilities into aerobic digesters and sludge thickeners.
EHRA completed a site-specific planning and visioning study for the proposed 470-acre San Jacinto Boulevard District (SJBD) in Baytown, Texas.
EHRA completed preliminary engineering, phase one environmental site assessment and schematic development for the widening of Northpark Dr. between US 59 and Woodland Hills Dr. EHRA also provided program management, drainage analysis and design, traffic engineering, environmental documentation and schematic design for the roadway, as well as grade separation at the Loop 494/UPRR railroad crossing.
EHRA conducted traffic operations and access management studies for the Northpark Dr. corridor. This corridor is approximately 2.2 miles long and has major signalized and unsignalized intersections and driveways that access various subdivisions and industrial developments. These studies laid the groundwork for the widening of Northpark Dr. from a four-lane boulevard cross-section to a six-lane boulevard complete street. The new street design includes low impact development drainage, conventional drainage, a grade separation at the UPRR crossing with mechanically stabilized earth retaining walls, two at-grade crossings for bi-directional frontage access, reconstruction of two concrete bridges over a diversion channel, intersection improvements, a roadway-adjacent multiuse path and traffic signal improvements.
Drainage analysis and design included hydrologic and hydraulic studies of both existing and proposed conditions to demonstrate that proposed project components would not adversely affect the 100-year floodplain in the area. The roadway and traffic designs contained horizontal and vertical alignments, cross-sections, plan and profile, sidewalk and bicycle accommodations, intersection layouts, traffic control plans and signing and pavement markings.
As the program management firm, EHRA coordinated with TxDOT, UPRR, the City of Houston Council District E, COH Planning and Development Department, COH Public Works and Engineering Department, Montgomery County, Harris County, HCFCD and area residents throughout the project.
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.
In work that could help prevent the failure of everything from bridges to dental implants, a team led by a researcher at Texas A&M University has taken the first 3D image of a microscopic crack propagating through a metal damaged by hydrogen. They have caught the crack red-handed! Previously, the only way to analyze such a metal failure was to look at the separated pieces of a completely fractured component, which entails a certain amount of guesswork. The new research shows what is happening at the crack tip as a part begins to fracture. As a result, the team identified 10 microscopic structures that make metals stronger and less susceptible to a key environmental factor -- the hydrogen around us -- that can damage them.
Their work is published in Nature Communications. It was conducted using two powerful tools at Argonne National Laboratory's Advanced Photon Source (APS), and represents a milestone for one of those tools as the first experiment performed by researchers outside of the development team at Argonne and Carnegie Mellon University (CMU). The study took eight years to complete, primarily because it involved huge amounts of data that were difficult to analyze. The raw data for the work would fill almost 400 DVDs. Further, the data looks nothing like a 3D model of the material.
