How the Dallas–Fort Worth Power Grid Works — and What’s Changing
Dallas–Fort Worth’s Power Grid in Context The Dallas–Fort Worth metroplex — one of the fastest-growing regions in the United States — is powered as part of the Texas electric grid managed by the Electric Reliability Council of Texas (ERCOT). ERCOT is the independent system operator (ISO) that controls the flow of electricity across most of […]
Detention Pond Design and Site Grading for Small Retail Centers in Texas: Balancing Drainage, ADA Access, and Code Compliance
Designing a detention pond and grading plan for a small retail strip center—particularly one under five acres in Texas—requires a careful balance of regulatory compliance, constructability, cost control, and long-term functionality. When ADA-accessible parking is part of the site program, the grading strategy becomes even more critical, because drainage, slopes, and accessibility standards are tightly […]
Water Treatment: The Quiet Backbone of Modern Infrastructure
Water treatment is one of the least visible yet most essential components of modern infrastructure. Long before water reaches a household tap or an industrial process line, it has passed through a carefully engineered system designed to protect public health, ensure regulatory compliance, and support economic activity. When water treatment works well, it goes largely […]
How Maritime Cranes Work in Modern Marine Construction: Stability, Lifting, and Precision on Water
In marine construction, cranes are among the most critical — and complex — pieces of equipment on any job site. Unlike land-based cranes, maritime cranes must operate on moving platforms, contend with waves and currents, and maintain stability while lifting massive loads with extreme precision. From bridge construction and port expansion to offshore foundations and […]
How do you make this?
Typically, one geotechnical boring is made in the vicinity of each proposed column on an elevated structure, in order to understand subsurface conditions to design the drilled shaft. The soil drilling should be of adequate separation (typically measured in pier diameters) from the column location, such that the drilling does not affect the bearing […]

From DHR’s own Herb Gears (former mayor of Irving):
In my first meeting with the Irving City Manager, as a young Councilmember and subsequent Mayor, I was told the most important issue I would ever deal with is water. In the 1950’s, Irving recognized the decreasing sustainability of water supplies for Texas cities, and began planning. Engineers, consultants, attorneys, and elected officials shared a […]
How would you fix this?
In this video, civil engineer David Recht takes a closer look at a sunken grate or drain at the Homewood Suites in Mobile, Alabama, explaining how he would approach fixing it. He points out signs of an underlying brick structure and an asphalt overlay, then walks through a straightforward, durable solution: bringing the grate back […]
