UNIVERSITY OF OTTAWA – Advance Contract Award Notice
2019-40206 ACAN – Ultra Precise Air Handling Units (AHU) and Humidifier Unit

BACKGROUND

Notice is hereby given by the University of Ottawa of its intent to enter into a contract with the following pre-identified supplier; Longhhill Energy, 124 Reis Road, Ottawa, Ontario, K0A 1L0 to supply:

Stolow Enclosure: One (1) Ecosaire air handling unit (ISO 6)
Stolow Enclosure: One (1) Condair humidifier unit
Bhardwaj Lab: One (1) Ecosaire air handling unit (ISO 8)

INTENDED USE

The University of Ottawa has acquired a state-of-the-art and unique in the world laser system, which requires clean room upgrades to allow for the operation of the laser. In order to deliver the clean room conditions required it is necessary to have precise control of the airflow in the lab. To this end, it is therefore necessary to have an ultra-precise air handling unit that can deliver temperature control within a range of +/- 0.5°C and humidity control within a range of +/- 3%RH.

SUBMISSION PROCESS FOR EQUIVALENT EQUIPMENT

Suppliers that consider their equipment functional, successfully tested, readily available and fully compliant to the ACAN minimum functional requirements listed below may submit, in writing, a statement of specifications, electronically to MERX, see instructions on page 4 of this notice, on or before the closing date of this notice. In the statement of specfications, the supplier must unequivocally demonstrate how their equipment, at minimum, equals, or exceeds the stated functional requirements.

If no other supplier submits a statement of specifications on or before the closing date of this notice, the competitive requirements of the University will be considered having been met. Following notification to any suppliers not successful in unequivocally demonstrating that their statement of specifications equals or exceed the requirements set out in this notice, the contract may then be awarded the the pre-identified supplier.

CLOSING DATE AND TIME:

Thursday August 8, 2019 precisely no later than 3:00:00 PM Local Time

JUSTIFICATION OF PRE-SELECTED SUPPLIER

Supplier: Longhhill Energy, 124 Reis Road, Ottawa, Ontario, K0A

Justification:

Due to the precise control required from the air handling units (AHU) and their requirements to work with the existing base building AHU, these units will effectively be functioning as one system. A complex array of sensors that is common to all units will be necessary to ensure the units are responding appropriately to changes in conditions during experiments. Furthermore, maintenance of these units will be integral to the continued operation of the laser lab and therefore equipment commonality is of the utmost importance. Minor differences in equipment or software introduces potential for errors that could be detrimental to the continued operation of the system within the required parameters. For these reasons, it is necessary to source all units specified to a single supplier.

To the best of our knowledge, Longhill Energy, as distributor of Ecosaire equipment, is the only company able to deliver a system with temperature control within a range of +/- 0.5°C and humidity control within a range of +/- 3%RH.
