Questions must be submitted electronically through IonWave at planotx.ionwave.net. No questions will be answered over the phone or through email.

The preferred method for proposal submission is electronically through IonWave. If you choose to submit your bid/proposal in person, Procurement personnel will be available Mondays and Wednesdays between the hours of 10 a.m. and 2 p.m. The person delivering the bid/proposal must call (972) 941-7557 upon arrival during those hours and wait in the lobby for someone to meet them to receive their bid/proposal.

Plano, TX 75074

Ph: (972) 941-7557

All responses are due prior to the published closing date and time. No late responses will be accepted.

Bids/Proposals will be opened, and the names of offerors read, on (Tuesday, July 28, 2026 at 2:00 PM CT). The reading will take place at City Hall. Tabulations for these solicitations should be available on Ionwave within 48 hours of the opening. In some cases, they may be available earlier. We ask that you limit exposure by viewing tabulations electronically through IonWave, rather than attending at City Hall.

Time Critical Bid/Proposal Deliveries: The City of Plano cannot guarantee, due to internal procedures, that any bids/proposals sent via US mail will be picked up and delivered by the closing date and time. It is recommended that critical bid/proposal deliveries be made either electronically through IonWave or in person as described above. It is further recommended that users review all electronic response attachments to ensure the uploaded files are able to be downloaded and viewed. Instructions for this, if needed, can be found in the Supplier Bid Response Quick Tutorial online in Ionwave or by calling Ionwave Support at 844-226-3862. Responses or parts of a response whether hardcopy or electronic that cannot be viewed may deem your submittal as non-responsive. In addition, the City reserves the right to request clarification in such cases.
