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 assisted with the district creation of Montgomery County Municipal Utility District No. 126 to accommodate a ±329 acre master planned community located in northern Montgomery County in the City of Conroe, south of League Line Road, west of Longmire Road, and adjacent to Lake Conroe.
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.
Project totaled 640 acres including 1256 Residential Lots. EHRA designed, created construction plans, publicly bid and preformed Construction management.
Mass timber building advocates are encouraged by the results of the world’s first blast tests on full-scale structures framed with the renewable construction material. The performance metrics and design guidance produced from the tests, largely on cross-laminated timber frames, will help developers and blast engineers use CLT walls and floors as framing for target buildings that require hardening based on perceived security risks.
“No live tests had ever been done on cross-laminated timber,” says Bill Parsons, chief operating officer for WoodWorks Wood Products Council, which organized the seven tests. The only previous tests had been shock tube tests, which shot air waves at CLT panels to mimic an explosive.
Tests at Tyndall Air Force Base in Florida, on loaded and unloaded specimens, varied the blast force, the material grade, the number of plies and other factors. In all tests, three conducted in the fall of 2016 and four last fall, the structures remained intact under “significant explosive loading well beyond their design capacity,” according to WoodWorks. Based on the results, “mass timber structural systems can effectively resist blast loads in the elastic response range with little noticeable damage,” says Mark Weaver, principal of Karagozian & Case Inc.
