IV. QUESTIONS AND ANSWERS

Q1: SP22 for waterproofing requires 3 coats of hot rubberized asphalt waterproofingmembrane — please confirm as the typical requirement has usually been 2 coats.

Al: The repairing will have waterproofing on both the bridge deck and the twoapproach slabs, counting the waterproofing on the deck as one integral membrane.The two approach slabs needs two separate waterproofing membranes. So 3separate membranes in total are needed.

Q2: Drawing S1 3, End Joint Detail B calls for a 4Ox8Omm deep sawcut joint filled withhot rubber but only 20mm asphalt fibre board — please confirm.

A2: The above number “40x80 mm deep sawcut” is revised to “20x40 mm deepsawcut”, see the revised drawing in Section Il.

Q3: In reviewing SP26 for tender item 49 Concrete Removal Type C , there is no mentionof how we are to be paid for removing delaminated concrete from the abutment faces. Inthe original tender documents, it was stated that this scope of work would be paid underitem 49. Addendum 4 removed this clause. Please confirm under which item is work tobe paid?

A3: In SP 26, tender item 49 “Concrete Removal — Partial Depth — Type C” shallinclude “Abutment Walls” in Clause 928.07.03, Please see revision to SP 26 shownon II. REVISED CONTRACT DOCUMENTS.

Q4: Referring to page 4 of addendum 4, paragraph 5 “There shall be no separatepayment for reinforcing steel, which are deemed to be included in the work, for ConcretePatches, Form and Pump” and “Concrete Patches, Unformed Surface”. The reinforcingsteel for Concrete Refacing, Form and Pump shall be stainless steel, as shown in theContract drawings”

There are stainless steel dowels and stainless steel reinforcing to be supplied andinstalled for the abutment refacing work. Is the payment for the stainless steel dowels tobe paid under tender item 57? Is the payment for the stainless steel to be paid under item37?

The description as noted in 2 in not clear. The tender includes specific pay items fordowels and reinforcing steel/stainless steel. By our calculations the work involved withthe refacing; dowels and reinforcing are included in the tender items 37 and 57 for therefacing work. If we are to include the cost of the stainless steel dowels as well as the

5

stainless steel reinforcement in tender item 54, then adjust the tender quantities down foritems 37 and 57 accordingly so that we are not carrying twice the cost of the work.Otherwise remove the clause ‘There shall be no separate payment for reinforcing steel,”from the above paragraph.

A4: There is no separate payment for reinforcing steel for Type A and Type Bconcrete patch repair. For Type C patch repair, reinforcing steel is measured andpaid into two pay items:- Stainless reinforcing steel rebar: Item 37;- Stainless steel dowels: Item 57.Please note that the Pay Item 57 also includes stainless steel dowels from the deckparapet wall construction; dowels in water drip reconstruction are paid in Item 60.Pay Item 54 only includes the concrete and is measured in volume.

Q5: Referring to the questions and answers section, A-2 in Addendum 4: The scheduleis changed to one season with extended working hours with a completion date of October2019; winter shutdown is not needed.The tender documents include a pay item for Bird nesting preventative measures item 61with SP detailing the following:

“During the migratory bird nesting season, the contractor shall not destroy nests duringthe migratory bird nesting season April 1 to August 31. The contractor shall only removeinactive nests outside the migratory bird nesting season September 1 to March 31”.The anticipated award date as specified in the contract will not be earlier than April 12,2019, thus missing the timing window to install preventative bird nesting measures(netting). If one had inspected the site during the mandatory site meeting, there are oldbird nests on the bridge girders thus confirming that birds do nest at this location. Thereis at least 4 months of work under the structure such as debris platform erection/removaland coating the structural steel. The completion date of October 2019 is not correct.Considering this construction constraint, please reassess the completion date.

A5: No work shall be permitted to proceed that would result in the destruction ofactive nests, or the harming of birds, protected under the MBCA and/or anyregulations therein. No Birds protected by the MBCA or species at risk wereobserved under the bridge during field investigations. Rock Pigeon and EuropeanStarling nests do not receive protection under MBCA.
