Where does the City of San Antonio post bids?
On its Bid & Contract Opportunities page, which lists each solicitation's type, department, release date and deadline. Goods and services responses go through SAePS; the City says public works such as construction, architecture and engineering are bid through CivCast (Become a Vendor). BidLasso collects the City's list every weekday: open City bids.
How do I register as a City of San Antonio vendor?
Pre-register in SAePS with your company details, Federal Tax ID and one contact email. The City validates the Tax ID and sends your login within 48 business hours, then you finish your vendor profile and add NIGP codes, which decide the solicitations you are emailed (City of San Antonio, Become a Vendor). Vendor Support: 210-207-0118.
Where are SAWS construction projects posted?
SAWS lists open construction and engineering solicitations on its Business Center Contract Solicitations page. Free SAWS vendor registration gets you email notices, plan holder lists and plans and specifications (SAWS vendor registration). Purchasing (goods and services) bids are on a separate platform. BidLasso subscribers get SAWS items from SAWS's own vendor notice emails. See our SAWS registration guide.
How do I register as a Bexar County vendor?
Register on the County's Supplier Portal. Registered suppliers get automatic bid notifications for the commodity codes they pick, and the County asks for a signed W-9. Bexar County Purchasing is at 1103 S. Frio St., 210-335-2211. BidLasso doesn't collect Bexar County postings. See our Bexar County guide.
How do I bid on Northside ISD (NISD) work?
NISD posts solicitations on Bonfire, where registration is free. The district says contracts over $50,000 in a year are competitively bid, and the Board awards contracts at its monthly meetings (Doing business with NISD). BidLasso doesn't collect NISD's Bonfire postings, so register on the portal.
How do I bid on North East ISD (NEISD) work?
Register on NEISD eBids (Ionwave) to join the Bidder's List and get email notices for the commodities you pick. Registering does not make you an approved vendor; you become one when you're awarded a contract. Construction bids are handled by NEISD's Construction Management & Engineering Department (NEISD Bids). BidLasso doesn't collect NEISD's eBids postings.
When does TxDOT let San Antonio District projects?
TxDOT lets construction and maintenance projects at its monthly statewide letting, held in Austin over two consecutive days; the schedule and each project's letting date are on TxDOT's contract letting page. You must be prequalified to bid. BidLasso lists advertised and upcoming San Antonio District projects with TxDOT's estimates: TxDOT San Antonio District lettings.
Where does the City of Austin post bids?
On Austin Finance Online's active solicitations list. All offers must be submitted online through eResponse, and vendors must register with the City first (City of Austin solicitations). BidLasso collects this list every weekday: open City of Austin bids.
