Visit the TBIPS / SPICT (EN578-170432/B) solicitation which is currently available on the Buyandsell.gc.ca site.
Refreshes are for 1) new suppliers who did not submit a proposal under the re-competition and wish to submit one, or 2) existing suppliers who wish to submit a proposal because they wish to add additional categories to their TBIPS profile. Existing suppliers who do not wish to add additional categories to their profile do not need to submit a proposal for a 'refresh'.
Welcome to the Task-Based–Informatics Professional Services Standing Offer and Supply Arrangement (TBIPS)
A TBIPS requirement is related to a particular activity required to address a specific IT need and is usually associated with a specified set of responsibilities.
The tasks involved are finite work assignments that require one or more consultants to complete. A task involves a specific start date, a specific end date, and set deliverables. Tasks are usually not large projects, although they may be subsets of a larger project. Tasks may require highly specialized work to be performed requiring a rare or unique skill or knowledge for a short period of time.
