Public-Private Partnerships or “P3s” refer generally to agreements between public entities and the private sector by which the private sector makes physical assets or services available to a public entity in exchange for payments over a term of twenty years or more. As authorized by Chapter 2267, Texas Government Code, the City of Houston has adopted P3 Guidelines through passage of City Council Resolution No. 2014-0027. Following these Guidelines, vendors may submit unsolicited proposals for P3 Projects. The City will review such proposals and decide whether to pursue the idea/opportunity presented. If the City elects to move forward with a P3 Proposal, the City will conduct a competitive process for the selection of a vendor and negotiation of a contract. Please refer to the Guidelines for more details. [link to the document here]

Types of Solicitations:
There are six types of solicitations used for procuring goods and services for the City of Houston Municipal operations. Here is a complete listing of our Glossary of Terms for your information.
- Purchase Orders (POs)
- Emergency Purchase Orders (EPOs)
- Formal Bids
- Informal Bids
- Request for Proposals (RFPs)
- Construction Contracts under $500,000
- Purchasing Cards (PCards)
Purchase Orders (POs):
Bids are solicited by telephone, fax or in writing by department purchasing personnel within their specific level of business. When bids are received they are analyzed, evaluated and a PO is issued to the low bid meeting specifications. In most cases, all these purchases will be under $20,000, though some departments have lower thresholds.
Emergency Purchase Orders (EPOs):
Depending on the nature of the emergency, bids may be handled in the same manner as POs, or in the case of severe emergencies, may not be competitively bid. City Departments’ can issue emergency purchase orders when possible; in other cases, Strategic Purchasing issues emergency purchase orders. You can view online a complete list of the Departmental Purchasing Units.
Formal bids are written solicitations exceeding $50,000 for goods and nonprofessional services and are taken in accordance with State law.
Bids are advertised for two consecutive weeks in the Houston Business Journal and minority papers, received by the City Secretary's Office on the advertised bid due date, opened and then publicly read in City Council Chambers (unless place of opening has been transferred in accordance with Section 15-3 B(5) of the City of Houston Code of Ordinances).
The City Purchasing Agent recommends awards for formal bids to City Council.
Most formal bids are awarded on the basis of lowest responsible bid. Variations on formal bids include reverse auction and best value procurement. Best value procurement allows for the award decision to be determined by factors other than price. Both of these approaches follow the standard notifications process but vary in the way the award is decided.
Prior to issuing a public bid invitation estimated to be in excess of $100,000, Strategic Purchasing reviews and researches each for the purpose of determining subcontracting possibilities. When it is evident there is Minority/Women/Disadvantaged Business Enterprise (MWDBE) subcontracting potential, a goal is assigned to give certified MWDBE suppliers additional opportunity to participate in City business.
Informal bids are solicitations valued at $50,000 or less for goods and nonprofessional services. Strategic Purchasing makes informal solicitations for requirements exceeding department authority by mail, telephone, or fax. After bids are received, they are analyzed and evaluated by the Strategic Purchasing Department who will then issue purchase orders. Informal Bids are classified as regulated contracts to attract MWDBE participation. When there is a capable MWDBE firm certified by the City's Office of Business Opportunity, the requesting department is required to solicit bids from that company. In addition, the requesting department is required to solicit participation from no less than three (3) certified MWDBE's if there are three or more capable firms.
Request for Proposals (RFPs):
Request for Proposals are used to solicit equipment, goods, and services of a highly technical nature. RFPs are taken in accordance with State law provision under Vernon's Annotated Civil Statutes (V.A.C.S. § 252), a unit of the Texas Legislative Council's statutory revision program authorized by the Texas Local Government Code. Under this law, the City solicits requests for proposals for information processing equipment, software and hardware used in conjunction with information processing equipment, telecommunications, radio systems, microwave systems, electronic distributed control systems and technical services related to this equipment. RFPs are also reviewed for MWBE opportunities.
Construction Projects involving improvement to City facilities amounting to $500,000 or less fall under this category. Sealed bids are taken in accordance with State law for various construction projects amounting to $500,000 or less. Bid Bonds are required on all construction projects. Projects exceeding $25,000 require bidders to submit a payment bond and those exceeding $100,000 require a payment and performance bond. The City Purchasing Director recommends award of contracts to City Council. Certified MWBE's are encouraged to bid as prime contractors.
Purchasing Card (PCard):
Some city employees carry a MasterCard for making immediate need and small dollar purchases for official city business. The PCard is used in lieu of petty cash or purchase orders.
It is of extreme importance to check the bid due date and time specified in each bid or proposal package. All formal Bids and Proposals must be submitted by the specified due date and time, in duplicate, to the City Secretary's Office, City Hall Annex, Public Level, (900 Bagby). Here is a complete listing of our Glossary of Terms for your information.
The City Secretary will not accept late bids. Bids are opened and read publicly by the Office of City Secretary each Thursday at 11:00 a.m., unless specified otherwise. This is a public meeting held at the above location and anyone may attend.
The Strategic Procurement Division makes bid tabulations available to the public after an award has been made by City Council. You can search for bid tabulations by bid name or bid number through our Search Engine. Copies of the tabulations will be provided to any supplier upon request for a fee as defined by the Texas Open Records Act. Previously advertised Bids and Proposals are also available upon request for the same fee.
Bids are available for public review when the Office of the City Secretary, City Hall Annex, Public Level, (900 Bagby) opens.
For further information, please contact the City Secretary at 713.247.1840. Here is a complete listing of our Glossary of Terms for your information.
In any bid and/or proposal package, you will find specific Insurance & Indemnification project requirements. Specifications will include necessary types of coverage and respective limits of liability. Before you can begin performing any services or delivering any goods on city property, proof of insurance must be provided to the Office of the City Purchasing Agent. We encourage you to view the Certificate of Insurance Form for Services Page 1-2 as required by the City of Houston. Note: Page 3 is optional

4. How do I find out about bids for construction projects?
Construction projects under $500,000 are found at http://purchasing.houstontx.gov/bids.html.
The Houston Airport System and the Departments of Public Works & Engineering /Capital Projects are responsible for construction, architectural and engineering contracts over $500,000 in value for the City of Houston.
If you are interested in bidding on these types of projects, you will need to login to the Public Works & Engineering Department Website: http://bidsets.publicworks.houstontx.gov/, or to the Houston Airport website: http://www.fly2houston.com/bidRFPAdvertisement.
Again, we highly encouraged interested bidders to attend the pre-bid or pre-proposal conferences.

You can also contact the assigned buyer for questions and further information about a specific bid or RFP.
5. Where do I turn in a bid or proposal?
All formal bids must be submitted by the specified due date and time in duplicate to the City Secretary’s Office, City Hall Annex, Public Level, (900 Bagby). The bid due date and time is specified in each bid/proposal package.
6. How do I find information about a bid or RFP?
Attending the Pre-Bid or Pre-Proposal Conference will give you the opportunity to ask questions about the specifications and general terms and conditions. This conference also allows for your guidance to find out who is interested in bidding or proposing on a particular contract, or you can contact the assigned buyer.
7. When and where do I locate your bid documents bid tabulations?
Bid tabulations are placed in the bid folder after an award has been made by City Council. You can search for the bid folder by bid name or bid number through our Search Engine.
8. How do I get paid for services or goods I provide to the City?
Submit your invoice to the billing department as specified on your purchase order. If you do not submit your invoice to the proper billing address, payment will be delayed.
To ensure timely payment, your invoice must adhere to these characteristics and include the following:
- The City of Houston Purchase Order Number
- Invoice exactly as shown on your City issued purchase order
- Goods and/or services must be itemized as to quantity, part number, description and applicable
- Invoices must show the department, division or section to which the goods and/or services
- All invoices must be submitted in triplicate (The City’s automated purchasing and financial
systems require a three-way match of the purchase order, the receiver and the invoice to
complete a payment transaction in a timely manner).
