PCD has provided structural design services for industrial facilities across a wide range of disciplines. From frac sand facilities to steel processing, refinery to manufacturing, and bridges to airplane hangars, our project exposure has been extensive. Heavy cranes, built-in rail systems, utility tie-ins, and sophisticated mechanical, electrical, and plumbing systems are commonplace and must be carefully coordinated during the planning of industrial facilities. Our experience with heavy building loads and associated foundations and structures allows us to arrive at solutions quickly and accurately. PCD’s professionals offer sound structural analysis and clear, concise drawings that provide straight-forward direction for builders to implement. Our past work with wide-span structures has made us especially adept at providing designs for the aviation field. From T-hangers with rolling doors to large, multi-plane hangars with complex folding door systems, our ability to provide input into the cost-effective design and construction of hangars is well-proven. As in all our sectors, industrial property owners benefit from their direct interaction with PCD’s professional design team.
Priefert Rail Crossing
Mount Pleasant, TX
Building Activities: Industrial Conveyor
Status: Completed 2017
Description: 8,064 square feet in size, this project serves as an overpass above the Union Pacific Railroad (UPR) for Priefert Manufacturing to transport product from one side of the tracks to the other. PCD, provided the initial design and worked with UPR during the review and approval process. After the project was approved by UPR, PCD completed structural engineering, bid out the project and administered the project during the construction phase. Challenges overcome during design and construction included significant grade changes on opposite sides of the tracks, locating foundations to avoid UPR right-of-way setbacks and utilities, and designing a structure to span the railroad without shutting down UPR’s cross-country rail service. The clear span bridge was designed to be built in three sections. The two sections on each side of the tracks form the buttress supports for the clear span section. These structural steel buttresses cantilever to the limits of the UPR setbacks and are supported by a drilled pier foundation system. After these sections were erected, the center portion of the bridge was assembled on the ground and hoisted into position by a heavy-lift crane. Since the project was a bolt up structure – almost 200 feet long and clear-spanning 110 feet, all subcontractor work was critical and allowed no room for error. The project’s flawless erection was attributed to precise foundation placement and coordination by the concrete subcontractor, a well thought out steel building package and the efforts of an experienced steel erector. The erection team, crane crew and welders provided for a seamless orchestration of the installation. Scheduling the lift between trains and threatening weather conditions, the lift took thirteen minutes, leaving rail traffic held up for only thirty minutes. This time frame easily completed the job within the 2-hour window granted by UPR.
Priefert Steel Tube Mill
Mount Pleasant, TX
Building Activities: Industrial Tube Mill, Production, Warehouse Storage
Status: Completed 2017
Description: PCD has designed a series of 39,200 square foot buildings to support a steel tube mill facility. This project was outfitted with a series of 35-ton overhead bridge cranes, capable of maneuvering 60,000-pound coils of steel throughout the entire footprint of the buildings. The buildings are “expandable” - designed to share columns as they expand in width and in length. Due to the high magnitudes of the lateral crane loads, the columns were designed with “fixed” bases. This led to large baseplates and anchors, requiring precise installation. Working closely with the concrete subcontractor, attention to detail led to speedy and trouble-free erection of the complex. Other structural features include large drilled pier foundations, heavy slabs-on-grade for carrying stacked coils of steel and masonry control rooms within the facility. Instead of having traditional gutters and downspouts, this building is equipped with internal gutters tied to underground storm systems which lead to an above-ground storm water retention pond. The complex currently stands at 206,400 square feet – and growing. PCD provided all required civil, structural and architectural engineering as well as administration of the construction.
Building Activities: Corporate Office, Trucking, Mechanic Shop, Warehouse Storage
Status: Completed 2018
Description: This office and industrial project totaled 37,000 square feet, including an 11,000 square foot office building, a 14,000 square foot mechanic shop and a 12,000 square foot warehouse, serving Pro Frac with a new home base in Odessa, Texas. PCD worked closely with team of architects and engineers, coordinating multiple structural and building systems. Features of this project included designing light gage framing in the office and admin spaces, masonry block walls, and a spread footing – slab-on-grade foundation system with capacity to allow for heavy machinery and storage.
