I am finding several instances, looking at fedbizopps,where A&E services are being announced and the intent is to establish one or more awards under the IDIQ authority of FAR Part 16.5. Several agencies (to remain unidentified) are seeking price proposals from firms who have received awards under IDIQ contract. I believe the confusion comes when contracting personnel read FAR 16.5 and find there is to be a fair opportunity to compete for the individual task orders. HOWEVER, they fail to read that part of the scope statement allowing use of IDIQ for A&E Services, but they miss the exclusion which requires selection to be based on FAR Part 36.6. The A&E selection procedure requires consideration of the professional competencies of the firm. After firms have been evaluated a single firm is selected for contract negotiation. That is when price comes in (task order or single award A&E contract). I find this especially when contract are contemplated for Cadastral Surveys (maybe people forgot that surveying is now covered by FAR Part 36.6). If you have found this occuring, OR if you believe that competitive price proposals are permitted/required....please submit your comments.
