Rehabilitation of North Electrical
Substation at Main Treatment Plant
The Works and Utilities Committee recommends the adoption of the report dated March 9, 1998, from the Interim
Functional Lead for Water and Wastewater.
The Works and Utilities Committee reports, for the information of Council, having requested, in camera, that the Audit
Committee consider further action in connection with this matter.
The Works and Utilities Committee submits the following report (March 9, 1998) from the Interim Functional Lead
for Water and Wastewater:
Purpose:
To obtain authorization to engage a consultant to provide engineering services for the rehabilitation of the North Electrical
Substation and related structures and services at the Main Treatment Plant.
Funding Sources:
Financing for the expenditure recommended herein has been previously approved by Metropolitan Council, and funds are
available under Water Pollution Control Capital Account No. WP160, Main Treatment Plant.
Recommendations:
It is recommended that:
(1)the firm of MacViro Consultants Inc. be engaged to provide engineering services in connection with the rehabilitation
of the North Electrical Substation and related structures and services at the Main Treatment Plant for the following
estimated costs including Goods and Services Tax:
(a)for pre-design and detailed design services, an amount not to exceed $293,000.00, including GST and including a
contingency allowance of $40,000.00 to cover additional work if necessary and authorized by the Commissioner of Works
and Emergency Services; and
(b)for general administration and site services during construction, an amount not to exceed $259,750.00 including GST
for a construction period of up to 10 months and a contingency rate not to exceed $6,550.00 per week including GST for
extension of services during construction beyond a period of ten months if necessary and authorized by the Commissioner
of Works and Emergency Services; and
(2)the appropriate City officials be directed to take the necessary action to give effect thereto.
Background:
By adoption of Clause No. 2 of Report No. 9 of The Environment and Public Space Committee on July 2, 1997,
Metropolitan Council authorized further funding for continuation of the program to upgrade facilities at the Main
Treatment Plant. This authorization included the North Substation upgrade at a gross estimated cost of $7,134,000.00 after
Municipal Goods and Services Tax Rebate.
In order to carry out this work, the Department requires the engagement of a consulting firm to provide both preliminary
and detailed design services for building rehabilitation or replacement, the removal of existing obsolete equipment and
installation of new equipment, the assessment and replacement, if required, of power feeder cables, ancillary power and
control systems, and related work as required. The consultant will further be required to provide services during
construction including general administration, resident inspection, system integration, operating and maintenance manuals,
commissioning and post-construction follow-up during the warranty period.
Discussion and Justification:
The North Substation at the Main Treatment Plant is the primary source of power to equipment within the plant. It was
constructed and placed into service approximately 40 years ago. The building, transformers, electrical panels, breakers, and
cables have been added to over the years, with some equipment also becoming redundant as various processes in the plant
have been decommissioned. Much of the electrical equipment is obsolete and can no longer be economically maintained as
parts are no longer available. The redundant equipment is to be removed; obsolete equipment is to be replaced with
equipment meeting the latest standards; and the aging building structure is to be either rehabilitated or replaced to ensure
building code conformance. A key component of the rehabilitation is to improve conditions in the partial basement crawl
space where many high voltage cables are either buried directly in soil, or suspended from the underside of the main floor
slab. This will improve the plant staff's ability to maintain these cables.
The current undertaking results from previous studies and consultant's reports which recommended renovation/replacement
of the existing facility in order to maintain reliable service delivery. It is consistent with Ministry of the Environment
requirements to maintain the equipment within our wastewater facilities.
In order to select a consultant to assist in this work, a selection process was carried out in accordance with current policy
generally as follows:
-the size of the assignment was assessed against the selection policy and the appropriate level of procedure was selected;
-a selection committee was struck including representatives from both the Water Pollution Control and Management and
Technical Services Divisions of the Department;
-ten firms selected from the Department's roster lists for the type of work involved were requested to submit "Expressions
of Interest" in providing the necessary engineering services for the project. Seven responses were received and reviewed by
the selection committee from which four were short-listed for further consideration;
-detailed terms of reference were prepared and written proposals were requested and received from the four short-listed
firms. Each proposal included a technical submission and a separate sealed cost proposal;
-each technical submission was reviewed, first independently and then jointly by members of the selection committee
with specific attention to each firm's response to the detailed terms of reference, and was evaluated according to a set of
pre-established criteria each with a weighting factor and maximum point score;
-following detailed review and discussion of the technical submissions, the selection committee concluded that three of
the four firms qualified for further consideration of their cost proposals and the other did not;
-following a preliminary review of the cost proposals, the three firms were interviewed in order to clarify and finalize the
specific scope of work required and the related cost factors for same; and
-on completion of all of the above, the selection committee concluded that the proposal submitted by MacViro
Consultants Inc. best met the overall project requirements, at the lowest evaluated cost, and all proponents were notified
that MacViro Consultants Inc. would be recommended for award of the assignment.
The estimated cost for this consulting assignment, including Goods and Services Tax, is as follows:
(i)Pre-design and detailed design services$253,000.00
(ii)Contingency allowance for design$40,000.00
(iii)Services during construction
(based on estimated construction period of 10 months)$259,750.00
Total estimated cost:$552,750.00 including GST
(iv)Provision for extension of services
during construction if necessary, not
to exceed an average cost of$6,550.00 per week
The assignment shall be performed in accordance with an agreement containing terms and conditions satisfactory to the
Commissioner of Works and Emergency Services and the Solicitor.
Conclusions:
Following a consultant selection procedure in accordance with current corporate policy, the firm of MacViro Consultants
Inc. has been selected by a consultant selection committee as best meeting the overall project requirements for engineering
services to rehabilitate the North Electrical Substation at the Main Treatment Plant, and should therefore be awarded this
assignment.
