The former Motorola facility, originally built in 1971, located at the corner of University Drive and Sunrise Boulevard in the City of Plantation in the greater Miami area, was purchased in 2013 by Torburn Part- ners of Illinois. The reconfiguration of this campus was designed by civil engineer Kimley-Horn & Associates. While Motorola will still retain a presence at the site, this redesigned and reconfigured campus, now known as Plantation Pointe, will now be home to the entertainment technology company, Magic Leap. Sheri- dan Healthcare will also make Plantation Pointe its headquar- ters, in addition to retail shops and restaurants. As part of the makeover, two existing lakes along front- age roads, were backfilled and relocated to make way for two additional out parcels. A new lake was excavated in another location on the site. To accommodate the new development, two long runs of large diameter box culvert piping, thousands of feet of other required drainage and hundreds of structures, 2,600 lf of 12-in. DIP water main, a new lift station and 2,100 lf of 12-in. force main were constructed. The general contractor for the re-development, Blue Water Partners, brought Ryan Inc. Southern on board to provide site civil work, including utility construction and earth moving. Ryan collaborated with the engineer and owner producing many valuable ideas that saved the project time and money. Ryan worked on the project from 2014 to 2015. The work, which involved engineering solutions as well as working around existing clients, has become more common in recent years, according to Paul Knight, project manager for Ryan Inc. Southern and immediate past president of NUCA of South Florida. "We are seeing more technical projects versus the large de- velopment projects that were common a decade ago," he said. "In these types of projects, you have the added dynamic of working with the owner to develop the site, while working to minimize the impacts on the existing residents who don't want to be bothered by construction." Challenges and Innovative Solutions The property is located at a major intersection and the ex- isting lakes wrapped around the frontage of the property. The owners wanted to create retail space by filling these lakes. The solution was to create a new lake on the back of the property that would generate the additional fill needed to fill the frontage lakes. Most of the onsite storm drainage flowed into the existing frontage lakes and the drainage shed had to be maintained. The solution was a storm drainage system that rerouted the onsite drainage from the existing lakes to the proposed lake. This major undertaking involved the installation of thou- sands of feet of 6-ft by 7-ft box culvert. Dewatering during installation, as well as storm run-off, had to be kept on site. Balancing the amount of excavation and area of the new lake versus what was being filled in the existing lakes had to be measured on a daily basis. Installa- tion of 2,100 lf of 12-in. forcemain and a new Master Lift Sta- tion were required. This work took place adjacent to a major roadway. Close coordination with the engineer and munici- pality made this work successful. "The key to successful completion of a complex project like this is patience," Knight said. "You want to complete the project quickly, but you need to have the flexibility to work with the owner as changes come up. From the very beginning, we were able to team with the owner in a collaborative environment." Subcontractors, Suppliers, Equipment Partners on the project included US Concrete Products, Arrow Directional Bore, Ferguson Waterworks, Rinker Mate- rials, Hanson Heidelberg Cement Group, Trio Development and ADS Pipe. A local supplier, US Concrete played a key role in the proj- ect by fabricating and delivering all of the precast drainage and sewer structures throughout the project.
