Chisholm 20 Commerce Park is a Class A, 4-building, 917,374 square foot business park situated on 69 acres. This best-in-class development will meet the demand of today's tenant with direct access to Interstate 20 and Loop 820, and it's located near strong labor and tremendous rooftop growth. Currently the No. 1 industrial market in the U.S. this year, Dallas-Fort Worth industrial demand continues to outpace supply. With an increased focus on e-commerce caused by the pandemic, many companies are finding DFW to be a strategic location for their logistics needs. This project was a full-site development including all utilities, gas, water, and road on three separate sites with TxDOT for the service road. There was one detention pond and one retention pond with a fountain feature. The buildings showcased 10-feet of glass at each entrance, there were extensive amounts of reveals in the panels that were highlighted with accent paint; and several retaining walls were on site.
As we worked on this project, we were pleased to identify our primary obstacles early that we had to overcome for a successful project. Logistics and coordination worked around an Oncor Service Facility located in the middle of the three sites (u-shaped). The project began during a concrete shortage in the DFW Metroplex area. This was mitigated with an on-site concrete batch plant, however, the volatility of available materials and additional costs to the budget were constantly monitored and impacted the schedule of concrete tilt wall panel fabrication. The Building 3 site was designed with a site fill over 35' vertically, retained by a stone gravity retaining wall of matching elevation. This was accomplished using on-site excavation of the other sites for a balanced site condition, thus preventing any excessive truck hauling costs. Due to Building 3 being installed on top of a large site fill, the entire excavation fill was monitored and tested for proper moisture, compaction, and density to prevent future building movement. Lastly, working with TxDOT and Oncor for schedules, approvals, material deliveries, and installations caused a 15 month delay. Recognition of these schedule impacts allowed the project to progress, with supplemental schedules to be implemented when the work became available.
The panels were standard 9 ¼" thick panels, however, each panel had numerous reveals, and the form liner was a deep ribbed design that could flex during concrete installation. All reveals and form liner had to match between the panels, and getting this laid out took longer than expected. After installation, the patch and rub process duration was tripled to produce acceptable fenestrations prior to painting. The panels were considered tall, and when combined with the site constraints, the panel fabrication locations and lifting designs were reviewed and modified twice prior to fabrication. This created the necessity for an oversized crane to reach long distances and culminated with the crane being located on top of fabricated panels and slab-on-grade for panel installation, thus slowing the overall installation process. Panel design also created many small spandrel panels to be installed in between large panels, creating window openings. To prevent excessive time loss due to crane re-rigging every three installed panels, a smaller crane was utilized to follow primary panel installation for the spandrel panels. While this reduced crane downtime, it also split the panel installation crew, thus slowing the installation process. Weekly coordination determined a schedule of crane use to maximize the crews efficiency for panel installation.
This was the first industrial warehouse project for the City of Benbrook. This project sets the bar high and prepares the path for all future initiatives in the city. The fire marshal, inspectors, and the city all learned from it as we walked each of them, step-by-step, through the multi-building construction procedure. This process allowed the project to progress with all involved parties working together, making the project successful for everybody. The project's impact to the area is beneficial for the growth of the local economy and future opportunities for projects with a similar enriched appearance. This project has set a baseline standard, maintaining an environmental standard with the installation of 1,300 new trees, and establishing the City of Benbrook as a place of growing residence and commerce.
