GOC2777228-CT-RFPQ - PDP4 Humidification

Currently, Place du Portage III (PDPIII) provides steam for humidification of Place du Portage IV (PDP IV). An ongoing major renovation project (PDPIII Asset and Workplace Renewal) will seek to disconnect this source of steam as base building equipment will be decommissioned; therefore, a new source for humidification of PDP IV is required. This project will replace the existing district steam connection which is currently generated from natural gas steam boilers in PDP III, and eliminate the reboiler at PDP IV. The chosen option is to install a centralized system from electric steam boilers located in PDP IV mechanical space in the basement level that provides the humidification for the entire facility. The proposed system will result in negligible greenhouse gas (GHG) emissions for the building, which currently has none. Furthermore, it will contribute to eliminating the need for natural gas as an energy source for building steam humidification, which was previously provided through PDP3. Given the requirement to carefully coordinate the project with the PDP3 AWR, BGIS has engaged the same consultant to prepare the tender package who also prepared the feasibility study. They are very familiar with both projects and should be able to expedite the design and substantive cost estimates to accelerate Gate 3 business case planning, mitigating schedule risk.
