Project Scope:

In 2011, a 10-year capital improvement plan began to expand the current Defiance Public Library and enhance modifications to the facility in phases. Phase one of the project, the Dome Project, involved new lighting and electrical upgrades.

Phase two of the expansion (The HVAC Project) was awarded exclusively to IPS, and involved removal of the original boiler system, baseboard heating, wall units, and abandoned wiring in the ceiling. IPS replaced the library’s HVAC system including all associated duct work, piping, and rooftop units, which were placed with a large crane.

In addition, the electrical service was upgraded from 400 AMP to 800 AMP, doubling the capacity. The building remained fully operational throughout construction.

Challenges:

Asbestos was encountered in several areas requiring specific management in order to eliminate the risk of exposure to library guests and the construction crew. The asbestos containing materials were contained and removed safely, without incident.

Additional challenges occurred during the new duct and piping installation. Major routing issues became apparent when trying to keep pipes and ducts concealed. IPS worked closely with the design team to develop a plan that ensured the pipes remained hidden, and historic preservation of the library was maintained.

Project Scope:

IPS was contracted by BGSU for this Central Heat Plant to Shatzel Hall Tunnel Restoration project. This included the replacement of the deteriorated Heat Plant Tunnel tunnel top below Thurstin Street and tunnel vault wall, pipe anchoring, and top where the secondary backup steam line enters the tunnel as it turns to the east under the parking lot heading towards Shatzel Hall, replacement of several deteriorated pipe rack supports in various locations throughout the entire tunnel, removal and replacement of up to five tunnel top expansion joints, insulating the pumped and high pressure condensate lines, plus installation of new LED lights and tunnel ventilation kiosks, etc. The utilities were contained within the tunnel system. The high pressure steam and the condensate lines were active during the construction of the tunnel renovation. IPS protected the piping located under Thurstin Ave during the replacement of the tunnel top and the walls in this area when the tunnel top was removed. IPS secured this area from accidental entry with proper protection (i.e. fencing, barricades, and signage) for the duration of the tunnel top replacement.

Challenges:

IPS dealt with the water infiltration and uninsulated piping issues before making any repairs to the tunnel structures. IPS replaced the section of the Heating Plant Tunnel for the portion under Thurstin Street. This tunnel top replacement required the removal of the roadway surface and the subbase located over the tunnel. This work was planned to be done for half of the tunnel at time to limit the disruption to traffic flow and locations and waterproofing to prevent future water infiltration from occurring.
