II. CLARIFICATIONS:

1. Q: The drawing indicates that work must be done in the TPZ’s, what additional measures

are required by Urban Forestry to allow excavation of pits in this zone? Will the successful

bidder need to hire an Arborist?

A: Excavation within the vicinity of tree roots and vegetation must be undertaken by hand

digging / hydrovaccuum excavation. There is no requirement for the successful proponent

to hire an arborist under this contract.

2. Q: Item 43 – Supplemental cost for the restoration of hard surfaces (gravel, asphalt,

interlock brick, concrete pavers, and retaining walls) in the vicinity of water service

replacements – 7 each; Typically these things are not measured with the same units, and

the drawings do not show the location of all water services. Until the area within the TPZ

is excavated and direction given as to how the successful bidder may proceed it is not

reasonable to call for a lump sum price for this work. Why is the restoration not broken up

into individual measurements?

2 of 20

A: Water service locations are identified on the contract drawings. Restoration costs are

to be included in the water service replacement cost. Seven (7) water service locations

have been identified in driveways requiring hard surface restoration. Item 43 is a

supplemental item to account for the restoration of these locations. Special Specification

80 speaks specifically to this item.

3. Q: In reference to Item 33, Hot ‘Tapping’ can be referred to as either ‘tapping sleeve and

valve’ or ‘insertion method’. Please clarify definition and unit of measurement.

A: Hot 'Tapping' refers to an insertion valve. The unit of measurement has been revised

as per A.1.1.4 above.

4. Q: Please see the contract drawings that refers to a 200mm tapping sleeve and valve at

Jane St and 2-150mm tapping sleeve and valves at Northover St and Peterdale Rd,

generally there would be a separate pay item for these connection, please advise.

A: Payment of these items is under Item 23 – Connect new watermain to existing

watermain, (all sizes) complete.

Asphalt, concrete and interlocking stone driveways disturbed during construction shall be

restored to equal condition or better. Driveway concrete curbs, including curb returns, sidewalks

and private walkways impacted by construction shall be reconstructed to original condition or

better.

The Contractor shall permanently restore driveways (all types) and sidewalks (minimum three
