A concrete cap will be placed on the end of the T. In addition, the steam pipe shall be capped. Assume asbestos insulation around steam pipe as this has been found in other areas on base.

3. Is there existing drawings available showing footers/spread footers for the building?

A: See attached asbuilt drawings.

4. As footprint will be less than 1 acre can we assume a full blow SWPPP will not be required but more storm water protection/BMP’s?

A: a full SWPPP is not required however storm water protection and BMP’s are required.

5. General Information (4.7.2) states comply with Corps of Engineers manual EM385 – confirm this is a requirement for this project.

Additional Clarifications from 90 CE

1. Note: #16 asbestos wall called out in asbestos attachments has already been removed

2. See attached written asbestos report

3. In regards to form DD1354: CE Construction Manager will assist with filling out this form

4. The provided asbuilts show the location of what was assumed to be an oil water separator, however testing of the water as well as the sludge at the bottom of the pit provided no traces of oil. It is assumed that there is no oil in this pit and that the connection to the sanitary sewer has been blocked with debris. Remove pit and cap sanitary sewer connection.

5. Limits of asphalt removal: assume that there are traces of asphalt within 25’ along east side of facility. Remove asphalt and regrade to achieve positive grade away from building site.
