06) Does the demolition include the intake piping?

ANSWER. If intakes are attached and accessible and in solid condition, they should be removed. If they are unable to be removed in single lengths by pulling by machinery from the work location or are too badly rusted to remove or would require significant digging or disruption of the streambed they may be cut off at or below the soil surface where they emerge from the streambed.

ANSWER. Yes, the door at the top does open and is accessible.

08) The diagram in the statement of work appears to indicate that the concrete structure has rebar. Is that correct?

ANSWER. It is unknown if rebar was used in this structure or not. The structure is of block construction and in most instances, rebar would not have been used in addition to the block, however, we have no records conveying the actual details of the construction so it is unknown if rebar is present.

09) Are utilities present at the site? If yes, is contractor responsible for disconnecting the utilities or have they already been abandoned?
