2. Replacement of corroded materials, as identified in the tender documents;
3. Provision of dedicated and heated make-up air for the chiller room’s continuous exhaust system;
4. Incorporation of a by-pass pipe to service the grey-water system when the pumps are off-line; and
5. Provision of pressure-reducing valves on lower levels of the grey-water system, to allow for improved service to the upper levels, via increased grey water system booster pressure.
