The construction team consisted of construction manager S. M. Wilson of St. Louis, architect Pratt Design Studio of Chicago, and Guarantee Electrical of St. Louis. The $45 million project was completed on time and under budget.

After winning the assignment by competitive bid based on schematic documents, the project team members devoted a year to preconstruction planning by using 3D modeling within a web-based system to achieve real-time design-engineering coordination among all parties.

The intensive pre-planning was required to ensure the hospital would operate seamlessly while it was operating entirely on back-up generators as Guarantee Electrical replaced and upgraded its central power system.

In fulfilling a design-assist role, Guarantee installed power, lighting, emergency, technology, data, fire alarm and security systems in the new wing and a new utility substation with site distribution to 5kV outdoor gear.

Guarantee constructed emergency backup power for the campus by installing two-1000kW diesel generators, paralleling switchgear housed in a new generator building.
