QUESTIONS AND ANSWERS

1. QUESTION: Page 11, Existing Conditions: West Abutment, Main Floor, approximately 700 SF concrete floor, Second Floor, approximately 550 SF concrete floor and East Abutment, approximately 400 SF concrete floor.

Based on this description, removing existing coatings from the walking surfaces of the floors. We are not painting the “Cove” the vertical and horizontal portion of the machine pads or raised structure supporting the structural steel in the Trolley Corridors. Is this the intent of this work?

1. ANSWER: The intent is for the painting of all horizontal concrete surfaces, no vertical surfaces. This does include the platform that the equipment motors/hydraulic tank is on but doesn’t include raised structure supporting the structural steel in the Trolley Corridors.

2. QUESTION: Section 6. Specific Safety Section-Lead Based Paint Abatement: d. Final Clearance Sampling: This sections calls for 3rd party independent clearance testing per ASTM E 1728. This standard is the sampling process, no clearance level is provided. Lead levels likely exist on all surfaces from erosion of existing lead paint. What is the proposed clearance level?

2. ANSWER: Clearance sampling shall be completed in accordance with ASTM E1728 and ASTM E3074. Samples must be analyzed by a laboratory recognized by the EPA’s National Lead Laboratory Accreditation Program (NLLAP). The SOW has been updated to reflect this information.

3. QUESTION: There is no mention in the scope of work of the steel walkway connecting the two areas of the second floor. Is the intent not to paint this area?

3. ANSWER: The metal steel walkway isn’t included in this contract.
