Alton Memorial Hospital Expansion

Location: Alton, IL
Completed: 2010
Client: BJC HealthCare
Size: 89,000SF


Guarantee Electrical demonstrated that it pays (literally) to plan ahead on the $45 million expansion and central power system replacement at Alton Memorial Hospital for BJC HealthCare in Alton, Illinois.

Assuming a design-assist role that optimized its contributions, Guarantee and project team members devoted a full year to preconstruction planning 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 entire hospital could operate seamlessly while its central power system was being replaced and upgraded in conjunction with the construction of a new four-story, 82-bed, 89,000-square-foot patient wing. The painstaking effort equipped medical care-givers to be totally prepared for pre-scheduled outages when the entire hospital relied on backup generators for power.

In addition to installing power, lighting, emergency, technology, data, fire alarm and security systems in the new wing, Guarantee constructed a new 34.5kV:5kV utility substation with site distribution to 5kV outdoor gear. It backed up the system by installing two 1000kW diesel generators, paralleling switchgear housed in a new generator building. Guarantee won the assignment by competitive bid based on schematic documents. Joining Guarantee on the construction team were construction manager SM Wilson and architect Pratt Design Studio.

Testifying to the excellence of the team’s results is the fact that the Illinois Department of Public Health (IDPH) approved the expansion in a single day. Typically, an IDPH inspection for a project of this size requires two to three days to complete and triggers re-inspections that linger weeks after the original tour. A space cannot be occupied until IDPH signs off.

Other features of the new four-story wing include a pharmacy, therapy and lab space, plus a patient-friendly lobby with reception and registration areas.
