Summarize the project's program, features and achievements.
Opening this 86,935 sf, 5-story Healthpark MOB 2 adds much-needed services to the nearby and on-site patients. This Class A Medical Office Building is on the same site as its 4-story Tilt-Up sister building, two parking garages, and over 475,000 sf of Continuing Care Retirement Community. Located across the street from the recently expanded Wake Med Hospital, Healthpark MOB 2 has made this location a one-stop-shop for patients with additional services & specialties such as Urgent Care services, Orthopedics, Primary Care, Pulmonology, Pediatrics, and a Sleep Center.
What obstacles were overcome related to the schedule, budget, program, specification, site, etc. on this project?
Working closely together, the Architects, Engineers, experienced Field Superintendents, and Construction Project managers determined the best way to lift a 5-story building on the site would be through having stacked single-story panels over 4-story panels. High voltage power transmission lines limited lifting along one side of the building, while the site's daily activity and already built areas limited available space for casting beds. This decision allowed the design to incorporate 32' wide panels on the 5th floor while creating additional visual depth at the thicker 4-story panel step. Sinewave form liner and reveal patterning similar to its 4-story sister building give the panels added texture before an opaque stain. Stone veneer was used in select locations to match the surrounding environment.
Communicate any engineering complexities or unique features of the panel design for this project.
Building and erecting the panels required tight scheduling and running through many sequences to determine the best and safest options. Panel reinforcing called for closed ties in almost each panel leg. With a limited site, bracing to the inside of the building was required. Through 3D virtual modeling, the Tilt-Up Contractor was able to study temporary brace locations to detect clashes between steel framing and other braces well before the problems arose in the field. Special crane software also determined if the main boom had clearance at the 4-story panels and maintained a safe working distance from the high voltage lines. This exercise determined the crane would require reconfiguring the main boom to add a luffing jib for a majority of the steel structure and the 5th story panels. Running through all these scenarios paid off as the erection went smoothly even with its complexities.
What is the potential for this project's impact on the community and/or environment?
Creating this additional square footage on the medical campus was essential to the community and the neighboring hospital. As the area continues its growth, relocating many services and specialties to a centralized location helps patients and medical professionals. Using Tilt-Up for this multi-story building led to a happy developer-client who delivered a building shell faster than traditional construction, enabling him to move in tenants sooner. This highly desired and anticipated Class A Medical Office Building was filled out quickly and has been an enormous asset since its opening.
