A1) PGandE has verified that gas and electric services to the Site have been disconnected. Water service to the Site has been turned off. Q2) Does Alameda County or the City of Hayward have permitting authority over this project? A2) Permitting authority for the Site itself resides with the Alameda County Public Works Agency (ACPWA). Permitting authority for areas of public domain is for the Contractor to ascertain. GSA has confirmed that no tree removal, excavation or grading permits will be required for work on the Site. Any other permits required for this project are the Contractor s responsibility. Q3) Is removal of all utility lines from the Site required? A3) Only those encountered/exposed in the areas of work. For example, if an abandoned gas line is encountered/exposed in one of the excavation areas, removal to the edge of the excavation is required. The Contractor need not chase it further. Q4) Adverse impacts to perimeter fencing and adjacent properties may be unavoidable when removing trees located on or immediately adjacent to the property line/perimeter of the Site. What agreements does the County have in place with neighbors regarding access to their properties in order to remove these trees and correct any adverse impacts?

This includes the five trees (tree #12, tree #21 and three trees on eastern property line) highlighted on the attached drawing SU1 - Topographic Survey, which drawing can be relied upon only as to the approximate location of the five trees. If contaminated soil remediation objectives make it necessary to remove a tree that the County and the Contractor previously agreed could remain in place, the County will negotiate required agreements for access to the affected neighboring properties. Q5) Will grading the Site flat and/or a survey of the Site at the completion of work be required as discussed at the pre-bid Site meeting? A5) A survey of the Site is not required. Grading the Site flat is not required. Required grading shall be as specified in Division 13, Document , Section Site Restoration. In order to comply with Section 1.08 we anticipate that edges of excavations will need to be knocked down and graded to an approximate 2:1 slope. For areas of excavation along the Site perimeter/property line, some backfilling with Site soils may be necessary to slope and stabilize the edge of the excavation. WRITTEN QUESTIONS SUBMITTED - RESPONSES, CLARIFICATIONS AND MODIFICATIONS Q6) With respect to traffic control at site ingresses and egresses, is an approved traffic control plan needed by the City or County?
