Questions people ask
What is NAICS 541330?
NAICS 541330 is the federal industry code for Engineering Services. Agencies attach it to solicitations for this work, and it decides which small business size standard applies.
Are these real government contracts?
Yes. Every row comes from the public feed of the official source, most often SAM.gov, and links straight to the official notice. Confirm deadlines and amendments there before you respond.
Will this page list every open engineering services bid?
No single search can. Agencies sometimes file this work under a neighboring code or describe it differently. Use this page to find leads fast, then check scope, eligibility, and attachments in the official notice.
How often is this page updated?
The list refreshes through the day from the same opportunity database that powers Captivaq. It currently tracks 314 open notices.
How do I hear about new ones without checking back?
Captivaq watches the sources against your company profile and alerts you when a fitting notice posts, then scores the fit and drafts the response. That is the product behind this page.
