Q/A

1. Will the contractor provide filters? If so, is there a list?

Yes, the contractor should provide disposable media filters. However, most of the equipment with filters at the station have permanent media that require vacuuming/cleaning rather than replacement. There is a disposable media filter list on page 31 of the PWS (Section 7.2 beneath the equipment list). Contractors are encouraged to verify the filters at a site visit as the list is developed from manuals.

2. Is the building control system within the scope of maintenance on this project?

Short answer is yes. There is no maintenance required of the controls software, per se, but there may be instances in which accessing the software is necessary for trouble shooting or repair work. The station has a Johnson Controls software license, so the contractor should be able to access it using that license, but should be familiar with Johnson Controls.

3. Will the contractor provide belts? If so, is there a list?

We do not have a belt list. The contractor can replace belts as needed and charge the parts to the $5,000 NTE parts line PWS Section 5.5.

4. The job plan mentions a maintenance check list. Is this the same as the check list in the job plan, or do we provide a check list?

The maintenance is checklist is part of reporting duties and relates to the maintenance schedule. The contractor is supposed to provide a schedule for the year’s maintenance of each item in the table in Section 7.2 based on their Job Plan column that shows how frequently each piece of equipment needs maintenance (monthly, quarterly, semi-annually, or annually). After each maintenance visit, the contractor should provide a checklist, or updated version of the maintenance schedule

Site and Equipment Access

4. Will the on-site computer be accessible as part of the work?

The station has a software license to use its Johnson Controls software and the contractor should be able to work with the station for any controls-related needs.

5. Will filters be provided, or are they the responsibility of the contractor?

Contractor is responsible for filters, most of which are permanent media that need only be cleaned rather than replaced. There is a replaceable filter list in Section 7.2, though on-site verification is recommended. The list was developed remotely using O&M manuals.

6. Is the water heater included as part of the service contract?

No, the water heater is not included, only the water boiler.

-Any required replacement filter for the boiler was inadvertently omitted.

3. They requested a list of all assets that needed to be maintained.

Who is the incumbent?

Answer: New contract; no incumbent.

4. Where are the 150 dehumidifiers? After seeing the dehumidifier on the third deck, they assumed it was the model of dehumidifier, but they said that it might need to be better distinguished in the contract.

Here is the information on the locations of the three humidifiers (listed below, locations from SAM) in the PWS’s equipment list. WM-150 is listed as the manufacturer name on the equipment enrollment form completed by the building contractor. I’ve attached a photo of DH-1 for reference.

DH-1 (SAM Eq. No. 4284714) located in Rm. 109 DH-2 (SAM Eq. No. 4284719) located in Rm. 210 DH-3 (SAM Eq. No. 4284723) located in Rm. 313
