Prefabricated Walls Help Sullivan Hospital Project Navigate Material Delays

A new medical office building at BJC’s Missouri Baptist Sullivan Hospital faced two construction challenges: working on an active healthcare campus and keeping the schedule moving through material delays.
The project team used prefabricated exterior wall panels to address both. According to a TJ Wies Prefab case study, the approach shortened the construction schedule by approximately six weeks. It also allowed other work to continue when custom masonry was delayed by several months.
Kadean Construction served as general contractor for the 17,287-square-foot addition at 751 Sappington Bridge Road in Sullivan. TJ Wies Prefab fabricated and installed the exterior wall panels.
Six Weeks in the Shop, Seven Days on Site
The exterior wall system was fabricated off site over six weeks. That work occurred while site preparation and other construction activities continued at the hospital.
The system included panels with an exterior insulation and finish system, commonly called EIFS, along with backup wall panels.
Once fabrication was complete, trucks delivered the panels to the campus. Crews staged two trailers at a time. A crane lifted each panel directly from its trailer into position.
The case study reports that the building enclosure was installed in seven days. Direct installation reduced material handling and the space needed to store materials on site.
Keeping Work Moving Through a Masonry Delay
Custom split-face block was delayed by several months. The prefabricated panels provided a water barrier that allowed the team to advance other work while waiting for the masonry.
Earlier enclosure also allowed roofing and interior framing to begin sooner, according to the case study. It reduced the need for temporary weather protection.
Window fabrication benefited from early coordination as well. TJ Wies provided guaranteed dimensions for the panels’ window openings. The glazing contractor could order and fabricate windows before the panels were installed.
That avoided waiting for field-built openings to be completed and measured. The case study credits the approach with removing masonry and glazing from the sequence of activities governing the project’s completion date.
Planning the Connection to the Hospital
Connecting the addition to the existing hospital required coordination across architectural details, structural requirements and multiple trades.
The team used building information modeling, Revit models and field measurements to identify conflicts before fabrication began. The owner, architect, Kadean and TJ Wies worked through the connection details before panels reached the site.
Less Assembly on an Active Campus
Moving wall assembly into a fabrication facility reduced the amount of exterior work performed from lifts and scaffolding. It also reduced on-site storage needs and congestion around the building.
Those changes mattered on a campus where healthcare operations continued during construction.
The case study estimates that the six-week schedule reduction avoided approximately $61,000 in general conditions costs. These are project overhead expenses associated with keeping a construction site operating.
The project illustrates how early coordination and off-site fabrication can give a construction team more flexibility when materials arrive late. In Sullivan, the enclosure allowed work to proceed while the team waited for the delayed masonry.
