Skysong 3 is the third of several projects for Plaza Companies’ 9.7-acre master planned complex. The DPR team worked for 12 months on the expansion, which includes a four-story, 145,000-sq.-ft. core and shell office building and a four-level parking garage with 1,024 parking stalls, complete with removable panels to allow for future expansion. This space already demonstrates its success with 100% of the available space currently leased and occupied.

DPR self-performed all interior drywall and framing, along with doors/frames/hardware installation. Most impressive, however, were the prefabricated exterior panels; DPR developed a complete virtual building model to vet and work through constructability concerns, visualize the installation sequence, and allow the team to order the exact amount of materials required. The latter contributed to overall time savings in shell construction with a six-man team, completing seven building elevations in just over six weeks.

All prefabrication work was done on site, minimizing material transportation throughout its lifecycle. The carefully sequenced construction of these panels also eliminated the need for scaffolding and chop saws, which saved the project thousands of dollars in addition to the cost savings associated with any rework that may have been needed using less thorough construction methods. 

Green Features

With traditional building models, a project accounts for a 5 to 8% waste factor, but the precision prefabrication work on Skysong 3 had less than 2% waste—a feature that helped it reach LEED Silver certification in 2014. 

In addition to the prefabrication panels, sustainable water and energy systems, along with indoor air quality and project waste were considered throughout the design and construction of Skysong 3. The team's use of sustainable water features, such as low-flow plumbing fixtures and native desert landscaping with high-efficiency irrigation systems, resulted in massive water savings for the project. Similarly, use of green technology, such as energy recovery wheels in the HVAC system, contributed to a high efficiency design that resulted in a 24% energy cost savings. Interior ventilation and air quality was further considered with the use of low-emitting materials such as adhesives, sealants, paints, flooring, and composite wood. Finally, more than 33% of building materials were manufactured using recycled materials.

During construction, DPR diverted 69% of all waste from the site from landfills to recycling centers.  

BIM Features

Building Information Modeling (BIM) and innovative field technology were key in the construction of Skysong 3's parking garage. DPR's BIM group developed 2D foundation drawings into a more complete 3D model. The accuracy of this model allowed the field team to resolve issues in the drawings before construction began, saving time and money in field rework.

The team used the 3D model to develop a model-based layout to generate the layout points needed for the garage footings. These layout points were then imported into an onsite robotic total station—a tool that translates the digital layout points into a real-time 360-degree laser system used in the field to pinpoint the footing coordinates within one-fourth of an inch accuracy.

The combined use of the BIM model and robotic total station resulted in zero adjustments and rework during the placement of the precast concrete members.
