The scope of work on TDIndustries’ new Houston complex included constructing a 38,000-sq-ft, two-story office building, a 14,000-sq-ft materials storage warehouse and a 6,000-sq-ft shop for the assembling and sectioning of ductwork as well as the prefabrication of pipe hangers and miscellaneous components.

The infrastructure was so limited on this rural site that the only available utility was electricity, forcing TD to move toward a self-sufficient campus. Since there wasn’t obvious stormwater drainage on site, the project team also installed a 30-ft-wide drainage system more than 1,000 ft long on an adjacent property.

At least 60 days of rain early on delayed sitework, and the Tax Day Flood of 2016 left the jobsite inundated. With rain delays continuing throughout the project, the team had to stabilize the ground more often than on typical projects.

TD’s engineering team developed a full-building energy model to compare the efficiency of four different types of mechanical systems, settling on a Daikin variable-refrigerant volume with a dedicated outside pretreatment system.

Additionally, TD’s manufacturing team prefabricated the plumbing, batteries and ductwork and created the piping assemblies to reduce rework, installation problems and time at the jobsite. The central air-handling unit was also prefabricated.
