August 25, 2023- Questions/Clarifications & Answers

Q1: Will the Owner provide for power and water throughout abatement?
A1: Yes

Q2: Are there any limitations to what shifts can be worked? 
A2: No. But the schedule of work will be approved and the contractor is to adhere to the approved schedule.

Q3: Will the abatement contractor be provided with keys to both buildings throughout abatement?
A3: No. Access will be provided either by City staff, or the Owner's representative CEC.

Q4: At areas where asbestos floor tile and mastic are on wood, can the asbestos mastic be left in place and demolished with the building versus removing all of the wood substrate?  This would be acceptable by Oregon DEQ.
A4: All mastic should be removed. If mastic is left on substrate, substrate should be removed as well.

Q5: The abatement contractor will have to demolish casework, wall/ceiling finishes, etc. in order to access concealed asbestos containing materials.   Can all demolition debris created from this activity be left on site for disposal by the demolition contractor?
A5: Yes

Q6: Is the warranty bond necessary for the project? 

A6: Contract Requirements Section 1.04(D) on page 12 of the ITB should reflect NO warranty bond. This project will NOT require a warranty bond.

Q7: If the main floor tiles and mastic are adhered directly to wood subfloor is chemical remover an option for removing the mastic? And staining of wood be acceptable? And or is buffering the mastic off the wood acceptable, leaving it in a rough / battered state? Or will the subfloor need to be removed, exposing joists and lower lever?
A7: Chemical removal and leaving the subfloor damage is acceptable. Some staining will remain due to petroleum based mastic. There should be no mastic debris remaining. Using chemicals with a floor deck (floor deck with metal blades) in using the mastic removal technique, is acceptable as long as the subfloor doesn’t contain any (ACM) friable debris. We understand that the petroleum-based mastic will leave a stain. The remaining subfloor will be tested for any (ACM), by bulk sampling.

Q8: Since there is no way of knowing exact LF of TSI, is biding this scope of work at 500LF and once 500LF is removed all other TSI would be a change order, acceptable? 

A8: If 500 LF of TSI is your estimate on the pipe insulation to be removed within this project, then that is the bidders estimate, and yours alone, not the City of Sandy’s. As mentioned within the specifications, the bidders scope of work is field verified. If and/or when ACM piping is discovered during the demolition efforts (e.g., piping that could not be identified during “your scope of” that was behind concrete walls), then a change order will be considered.

Q9: CEC (Klyer) pointed out a concealed pipe in an existing tunnel that was behind a closed door that wasn’t shown on the 1^st walk.  Can you confirm the length of that tunnel.
A9: 100 LF Straight then turns right for 70 LF 

Q10: It was addressed at the 1^st walk that contractors were responsible for verifying actual footages of the materials listed in the CEC survey.  How do we price concealed materials (TSI in particular)?  You can only verify what you can see.  Will unit rates be applied to deal with this condition? 

A10: All TSI that was accessible during the walk through should be included in the bidders scope of work and for all unknown TSI, unit rates will be applied. The contractor will be responsible for the soft demo. 

Q11: Want to verify that power and water will be available to the successful contractor at no cost to execute the work. 

A11: Yes

Q12: Want to verify that the CAB panels as listed in the CEC survey are a double panel (CAB on the interior and exterior faces with an insulation layer between the faces). 

A12: Please quote as double panel but if the CAB is only single panel the City will expect a credit and this will be verified by the onsite project manager. Credits will be issued based on the unit pricing submitted in the bid. 

Q13: Will the city be responsible for building security once the building envelope has been opened (CAB infill panels removed)? 

A13: Yes

Q14: Will builders risk installation floater be required for this work ( page 80 2.2)? 

A14: Yes

Q15: Has any exploration of the upper floor systems been performed during the survey process?  Specifically, can anyone tell me whether or not there is a subfloor present.  Typical wood floor systems would consist of the floor tile, underlayment, subfloor and then the floor joists.

A15: Floor tile, Underlayment, the Subfloor, then Floor Joists
