McClure Engineering Completes Ranken Jordan Pediatric Bridge Hospital Expansion

By on May 14, 2019

The Ranken Jordan Pediatric Bridge Hospital added upwards of 83,000 sq. ft. of new patient care and support space to its existing hospital facility. Except for the chilled water system, new MEP systems needed to be installed to exclusively feed the new addition. McClure Engineering was contracted as the third-party commissioning agent to oversee the construction, testing, and turnover of these critical MEP systems.

Project Deliverables

Prior to the commissioning project, McClure Engineering conducted a peer review of the design and provided feedback, influencing the final system design and control.

Where applicable, the design, installation, and controls implemented for these systems were required to mimic those of the existing facility to ensure ease of maintenance and operability.

Three (3) new air handling units (AHUs) working in parallel, variable volume terminal units with hot water reheat, redundant system return fans, and building relief fans were all installed. The AHUs provide conditioned air with constant temperature and humidity, which is then distributed through the terminal units to the individual zones. The heating hot water system contained three (3) new boilers and associated pumps, providing heated water to the new expansion terminal units and AHUs.

The chilled water system required two (2) new air-cooled chillers and pumps, providing cooling to the entire building. The electrical distribution system contains a new generator (complimenting the existing generator), four (4) new transfer switches, and related panels and transformers.

As this project was an addition to an active healthcare facility, infection control was paramount to all activities on the site.

As a third-party commissioning agent McClure Engineering:

  • Participated in regular owners’ coordination and project contractor meetings.
  • Verifed the physical installation of the MEP systems, including the mechanical equipment and accessories (ductwork, piping, pumps, fans, internal components, control devices, specialties).
  • Checked the operation of each individual control device across its full range. This also included safety verifications to ensure that the systems respond appropriately when faced with catastrophic conditions (freezing temperatures, fire alarm, loss of utility, etc.).
  • Checked the system to ensure it could maintain setpoints and adapt to both setpoint and load changes. McClure tested all the systems in their “typical” ambient conditions (i.e. winter for heating and summer for cooling) but also observed them in their “off” seasons.
  • Provided training support for the facility’s staff on all commissioned systems.
  • Issued a formal commissioning report detailing its approach to the project.
