THE CORPORATION OF TAY VALLEY TOWNSHIP REQUEST FOR PROPOSAL

ENGINEERING SERVICES

TO REHABILITATE TWO (2) BRIDGES AND RECONSTRUCT ONE (1) STRUCTURAL CULVERT

CONTRACT #2018-PW-007

ADDENDUM NO. 2

of 3

THIS ADDENDUM SHALL BE INCORPORATED INTO THE RFP PACKAGE AND SHALL FORM A PART OF THE CONTRACT DOCUMENTS

Date Issued: June 4, 2018 Issued By: Amanda Mabo, Clerk

Please note the following changes, corrections, additions, deletions, information and/or instructions in connection with the RFP Package. Failure to acknowledge receipt of this Addendum as per Part “A” – Information to Bidders may render your submission non-responsive. This addendum is to address the following question(s) and clarification(s): Question 1: Would you confirm the location of the culvert to be replaced in 2018? Answer 1: The Culvert is 800 metres east of Menzies Munro Side Road and 700 metres west of Noonan Side Road. The location noted in the RFP and in the OSIM report is incorrect. See attached map. Question 2: Could the OSIM data associated with the three sites be made available? Answer 2: See attached 2016 inspections for the three sites. Question 3: Please clarify hours to be included for the Contract Administration and Site Inspection services during construction. Please confirm that the 20 hours per week per site (8 week duration for each bridge and 3 week duration for the culvert) is only for site inspection services and that additional hours are to be included to cover additional tasks listed for Construction.





ADDENDUM NO. 2

of 3

Question 3: Yes, additional hours are to be included to cover the additional tasks listed for construction. Question 4: Please clarify if we are to include materials testing costs during construction. Answer 4: The Consultant will be required to obtain three quotes for material testing however the Township can be directly invoiced for the testing services and therefore testing costs should not be included in the submission. Question 5: Please confirm construction staging assumptions for completion of the work. i.e. will full road closures be permitted with implementation of a detour Answer 5: It is assumed that Noonan Side Road Bridge and Upper Scotch Line Culvert may be full road closures and Glen Tay Side Road Bridge will have to be staged construction.

Inspection Comments

Found culvert 2016, date of construction estimated. Culvert is at end of service life and should be replaced within two years. Capital estimate is for a steel culvert replacement. A concrete culvert will have at least twice the service life as a steel culvert, and should be considered.

Cost of existing structure removal: $6,000

Instalation Cost for Similar Size Steel: $19,000

Cost of excavation: $11,000

Cost of asphalt removal: $2,600

Cost of road replace: $17,000
