2 Tender Contract Addendum 1 con t Page 2 QUESTIONS/ANSWERS Q1. Where are we to include for the Catch basin Junctions? They should be under their own item 7.71 Service Junctions. A1. Payment for these connections will be incidental to other tendered items Q2. Where are we to include for the connections to existing piping at the new manholes? The manhole item says nothing about connecting to existing piping, this should also be under its own item A2. The schedule of quantities is adjusted to reflect the inclusion of manhole connections Q3. I count 5 SW-1 catch basins, not 4. A3. The correct number is 6 SW-1 catch basins. The schedule of quantities is adjusted to reflect that number Q4. Can you confirm for item 10.6 regarding the BC Hydro Drawing in Appendix 2, are we to supply and install everything shown on this drawing, including the 2 new hydro poles, pilasters, Type 832 Junction box, and all required conduit?
