"It's an ingenious system and you see that it all looks continuous and there are no nail marks on top of the deck," says George. And according to him, the six thousand square feet that was used in the project makes it one of the largest installations of the material in Texas. The cook center, fireplace and fire pit are veneered with Lueders limestone. The bas - es of the pergola's columns are solid Lueders stone, with the remaining portions con - sisting of wood frames clad- ded with the treated wood. It Takes a Team George complimented the craftsmen saying, "They did a fabulous job of merging it all to make it look seamless." The project managers were Craig Chap - man (softscape and irrigation), Dan Hall (water feature), Robey Canaday (land - scape lighting and tree pruning), Jorge Burbano de Lara (commercial landscape manager / estimation) and Bram Franklin (planting design). Thornton Tomasetti, Nicolas Saenz, Ph.D., P.E., S.E. (principle) and Payden Johnson (project manager) are credited with the structural engineering and load testing - Mike B. Davis, RPLS of Alpha Land Surveying, Inc. with the survey and layout of design. Frisco Lumber Co. handled the wood - work, Adventure Play Systems installed the synthetic turf and rubberized surfac - ing, and United Metals was in charge of the pergola fabrication and installation. Helping out on the job were skid steers, mini skid steers and mini excavators. Rented machinery included a Skytrack to move all the materials from street level to the deck level, and a 40-ton crane to move large boulders for a koi pond and the outdoor furniture, which weighed up to 10,000 pounds. George said that transporting all materi - als from the street level to the deck level was one of the biggest challenges, as was laying the synthetic turf, wood deck and rubber surfacing in such a manner so that the stormwater will drain to the existing storm basins. He also noted that laying out the curvilinear design as per the pro - posal and managing the execution of that brought its own demands. The sequenc - ing of the various stages was also tricky as Left Every five feet of the elevated walkway, weepholes were created in the direc- tion of the slope so that all water that collects on the 38,000-square-foot area drains to the existing nine catch basins. Below Inside the pergola's columns are steel posts on which the whole weight of the structure sits. Solid Lueders limestone, which is quar- ried in Texas, makes up the outside of the first 36" of each of the columns. On top of that is a 3" slab of the material. Then a wood frame clad with wood left over from the walkway and deck continues to the top. The woodwork took 2 days per column to complete. The covering is built with custom matrix panels framed with 6"x4" steel beams. Concrete Masonry Units (CMUs) veneered with the limestone comprise the fireplace and cook center structures whose countertops are also Lueders stone. Four fans and string lights were the final touches.
