Construction RFP vs. RFI vs. RFQ

Construction RFP vs. RFI vs. RFQ

If you have worked long enough in construction, you have probably come across the terms RFP, RFI, and RFQ. What do they mean, and what is the difference between these terms?

RFPs, RFIs, and RFQs are all necessary tools for minimizing risks and managing expenditure in a construction project. This article will discuss the difference between an RFP, RFQ, and RFI and their application areas.


RFP, RFI, RFQ, what’s the difference?

These three documents are similar in function but differ in their contribution to the supply chain process. In procurement, clients seek quotations, proposals, and information from suppliers. 

Having a clear understanding of the differences in the requests helps one come up with a request that best suits their needs before deciding on a supplier. 

Lumping all these requests together can hinder the procurement team from using all the distinct features of a particular sourcing tool. Below is a clear description of these procurement requests and their functionalities.

Request for information

The RFI (request for information) comes before other procurement requests. Some organizations need an RFI before starting the procurement process. The RFI procures general information on items and services you may need to purchase and the vendors.

Procurement professionals primarily use RFIs used to help familiarize themselves with the market before soliciting services. By systematically reaching out to different vendors, procurement teams can best compare market dynamics and what is most feasible for them.

RFIs do not give all the information necessary to purchase or select a service. Still, they influence the decision-making process, and the procurement team zeroes in on what they need when authoring RFPs and RFQs.

The structure of the RFI contains an introduction outlining the problem the procuring organization has. RFIs generally cover location, capacity, size, production capabilities, market trends, and other high-level information customs to the project.

The RFI also explains the scope of the problem and expectations of potential solutions. It references all the abbreviations and terminology and gives a clear template to help vendors respond with a satisfactory RFI.

Since the RFI is a fact-finding document, the questions need to be open-ended to allow the vendor to fully describe what they offer and their business solutions to meet your challenges.

The RFI is not binding on the supplier or the requesting company. The RFI helps the client understand the market and allows vendors to identify potential new clients and showcase their skills.

After sorting through RFIs, procurement teams can use the knowledge learned to structure their RFPs and RFQs.

Request for proposal

The request for proposal (RFP) is a formal document for seeking proposals from service providers on valuable assets, services, or commodities. The RFPs then evaluate and compare what the service providers can offer and which has the best proposal in terms of budget and project delivery.

The RFP follows a strict timeline, vendor response, and content rules. Depending on the market’s size, a client can send an RFP to several prospective suppliers. People and organizations commonly use RFPs when looking for technical expertise or complex and sophisticated building projects.

The RFP requests information from suppliers on how they will handle the project. It also shows the supplier any in-house solutions the client has, and the supplier can offer an alternative. The RFP is also specific and concise and is used to pick a vendor at the decision stage.

The RFP often turns into a bidding process since the main goal is to give vendors enough information to propose a reasonable solution while still giving them enough room for creativity and applying the best business practices.

In some projects, the procurement sourcing process ends at the RFP, but for others, it proceeds to the RFQ (Request for Quotation) to ensure there is a fair price evaluation among the vendors.

Request for quotation

The request for quotation (RFQ) is also known as the invitation to bid in the government and public sector.

An RFQ usually is the last stage of the sourcing process but can sometimes come before RFPs if the price is a critical differentiator for the project.

When a client forwards an RFQ, they know the problems they need to solve and the solutions necessary. The RFQ has more exact specifications than the RFI and RFP, as the client knows what is essential for the project. The client knows how much supplies they need and is looking to have an idea of the costs. 

Unlike the RFP, the RFQ does not allow vendors to offer creative solutions, but it looks for vendors to complete the project using the procuring method the client has chosen.

The RFQ is primarily about costs, and a detailed RFQ has all the components influencing prices. The RFQ has a list of products necessary for the project and the features and functionalities of these products. The RFQ also notes the quantity of goods required, the expected delivery dates, and the standard payment terms.

The RFQ usually is well structured to give a clear picture of the client’s needs. This makes it easy for service providers to provide reasonable cost estimates.

A thorough RFQ helps you judge if a vendor can meet your organization’s needs. It lets you evaluate whether a supplier offers the services you need at the intended costs. Only issue an RFQ when you have the specifics of what you need to procure.


The RFI, RFP, and RFQ have different functions, but all have the primary goal of assisting clients in getting the best suppliers for their projects. The RFI educates the client, helping them understand the potential solutions vendors offer, the RFP compares the different values vendors provide, and RFQs detail the costs for meeting project requirements.

Combining the RFI, RFP, and RFQ simplifies the supplier selection process and saves clients a lot of time and money. It also helps clients build long-term relationships with vendors as they quickly find vendors that meet their individual needs. A client should use
