Commercial Crew Transportation Capability (CCtCap) – Launch Complex 41

Challenge Design-Build Project Delivery Addressed

Design-build allowed the entire team to be brought in from day one. Because of the complexity of the design and the flexibility needed to adapt to any program modifications, design-build allowed the client the ability to make real-time modifications and have Hensel Phelps provide them with the real-time cost of those modifications. The design-build delivery approach also was critical to the success of the project due to the necessity of designing constructible tier modules for the Crew Access Tower to be erected on the Launch Pad and installation/removal of the Crew Access Arm on and off the offsite test stand.


The CCtCap project for United Launch Alliance provided the retrofitting of LC-41 to accommodate the new CST-100 Starliner Space Capsule. The project includes a new Crew Access Tower (CAT), a Crew Access Arm (CAA) and modifications to the platforms inside the existing Vertical Integration Facility (VIF) building adjacent to the Launch Complex. The CAT supports the CAA, which is moveable by a hydraulic system and will allow future astronauts safe, reliable access to the capsule.
