Panel Placement
Enquiry
Sheet 31A panel placement alternative panel placement plan. It appears the contractor would be allowed to have 6 panels on either end of the bridge prepared for ductal at the same time. There is a reference to completing this simultaneously. This would require 2 complete demolition teams, installation teams, etc. Would the Ministry allow this to happen concurrently, and then a cast of the 12 panels to happen simultaneously?

Response
As noted in the alternative placement sequence, if the Contractor elects to undertake this sequencing then all works must occur simultaneously and symmetrically. This will require additional workforce as necessary and is permitted. This will therefore allow 12 panels of the respective stage (6 on the west and 6 on the east of that stage, on opposite ends of the bridge) to be placed prior to UHPC placement. This will permit the Contractor to pour 12 panels instead of 6. The intent of this alternative sequence is to permit the Contractor a means of expediting the work and pour more panels in a shorter period of time. As noted, if this alternative is selected, Stage C must be undertaken simultaneously and symmetrically about the centreline of the bridge. The requirements of Note 7 regarding placing UHPC “no later than after 6 panels have been installed” still apply. A symmetric Stage C pour will therefore require UHPC for the 3 panels at the west side of the stage limits being poured simultaneously and symmetrically as the 3 panels at the east side of the stage limits to ensure that criteria of pouring UHPC no later than after 6 panels have been installed as been met for this stage.
