The bidding process in the construction industry is how projects are awarded to contractors, creating a fair way for companies to compete and for project owners to find the right fit. However, understanding each step can make all the difference in winning or losing a job.
This guide teaches the complete construction bidding process, how to estimate costs accurately, submit competitive bids, and avoid common pitfalls. Whether you’re new to construction or looking to improve your bidding strategy, this post will help you confidently approach projects, knowing each step of the process and how to maximize your chances of success.
Stages of the Construction Bidding Process
The construction bidding process includes several key steps, each designed to ensure that the best contractor is chosen.
Here’s a closer look at the main stages, from finding project opportunities to signing the final contract.
1. Bid Solicitation
Bid solicitation is the first step in the bidding process. It’s how owners announce a project’s availability and invite contractors to apply.
There are three main types of bid solicitations:
Open Bids
Anyone who meets the basic requirements can submit an open bid. This type is common for public projects, like government buildings or highways, where rules require that all qualified contractors have a fair chance to apply.
Selective Bids
For a selective bid, the project owner invites only certain contractors who meet specific criteria. This could include experience in similar projects or a history of reliable work. Selective bids are more common for private projects, where owners can be more selective about whom they hire.
Negotiated Bids
A negotiated bid means the project owner directly discusses terms with a preferred contractor rather than having a formal competition. This type is used when the owner knows who they want to work with or when the project is highly specialized.
Contractors stay informed about these bid opportunities through various channels, including industry websites, government postings, or even word of mouth. Once they find a project that interests them, they prepare for the next stage: pre-bid preparation.
Pre-Bid Preparation
In the pre-bid preparation stage, contractors examine the project details to determine whether it fits well. They must carefully review the project requirements, including what work needs to be done, the expected completion time, and any required materials or techniques.
Contractors also conduct risk assessments to identify any challenges affecting the project. They might visit the site to examine the area and look for potential issues, like difficult terrain or environmental concerns. Site visits provide firsthand insight that can prevent costly surprises later on.
Another part of this stage is reviewing key documents: Requests for Qualifications (RFQs) and Requests for Proposals (RFPs). RFQs help project owners determine if a contractor is qualified by asking about their experience and skills. RFPs focus on the contractor’s proposed approach to the project, including cost estimates and timelines.
3. Cost Estimation and Quantity Takeoff (QTO)
Once contractors know the project requirements, they move on to cost estimation, also known as Quantity Takeoff (QTO). Cost estimation involves calculating all the expenses needed to complete the project, including materials like concrete or steel, labor costs, equipment rentals, and other fees.
It is crucial because it helps contractors propose a price that covers their expenses while remaining competitive. Many companies use specialized software for this step, which helps ensure accuracy and keeps calculations up-to-date with current market prices.
Accurately estimating costs can make a big difference in winning the bid, showing the owner that the contractor has planned carefully.
4. Bid Submission
With cost estimates in hand, the contractor is ready for bid submission. A bid package includes everything the owner needs to know about the contractor’s plan. This package outlines the project scope, timeline, detailed cost breakdown, and what makes the contractor uniquely qualified to handle the project.
A well-prepared bid package does more than present numbers; it also highlights the contractor’s experience, safety record, and other strengths.
For example, if the contractor has completed similar projects on time and within budget, they should mention this to build trust. The goal is to make a robust and competitive case for why they are the best choice.
5. Bid Evaluation and Selection
Once bids are submitted, the project owner reviews them. This step is called bid evaluation and often involves “bid leveling.” Bid leveling means comparing each bid in a standard format, making it easier to see the differences in cost, timelines, and qualifications.
The selection process often focuses on the lowest bid for public projects, like those funded by government money. This step checks that taxpayer money is spent efficiently. However, in private projects, owners can consider more than just price.
They might consider the contractor’s experience, safety history, and overall value. This process, called value-based selection, allows the owner to choose a contractor based on factors beyond cost alone.
6. Contract Formation and Negotiation
After the owner selects a contractor, both parties negotiate and finalize the terms in a written contract. This contract outlines each side’s responsibilities, including payment schedules, deadlines, and other requirements.
There are several common types of contracts:
- Lump Sum: The contractor agrees to complete the project for a fixed price. This contract type is straightforward but puts the contractor at risk for cost overruns.
- Cost-Plus: The project owner agrees to pay the contractor for all actual costs plus an additional profit fee. It offers flexibility, but predicting total project costs can take longer.

- Guaranteed Maximum Price (GMP): The contractor sets a maximum price, and any costs that exceed it are the contractor’s responsibility. This type limits the owner’s financial risk.
- Unit Price: The contractor sets a price for each unit of work, such as per square foot of building. The final cost is based on the total units completed.
The contract formation stage is essential because it creates a legal agreement that protects both parties. Once the contract is signed, the project can officially begin, with the contractor mobilizing resources and the owner ready to oversee the work.
Each stage of the bidding process builds toward this moment, assuring the owner and the contractor are set up for a successful project.
Major Decisions in Shaping Construction Bidding
In competitive bids, different factors influence how contractors approach their proposals.
Project Delivery Methods
Project delivery methods guide how a construction project is organized, from planning to final build, affecting costs, timelines, and team roles.
- Design-Bid-Build (DBB): DBB, commonly used in government projects, separates design and construction. First, the owner hires a designer. After plans are complete, contractors bid based on the final design.
- Design-Build (DB): In Design-Build, a single contractor manages both design and construction, which allows for greater collaboration and faster project timelines.
- Integrated Project Delivery (IPD): IPD brings together the owner, designer, and contractor, creating a collaborative team that shares risks and rewards.
- Multi-Prime Contracting: The owner can directly contract with multiple parties, such as the architect and subcontractors. This gives the owner more control but demands careful coordination to avoid conflicts and delays. Skilled management is essential to ensure smooth communication across teams.
- Public-Private Partnerships (PPPs): A government agency partners with a private contractor who may handle design, construction, financing, and maintenance.
Procurement Methods
Procurement methods define how project owners select contractors, balancing price, experience, and expertise.
- Low Bid Procurement: It awards the contract to the lowest-priced bid, making it a straightforward choice that ensures cost efficiency. It is common in government projects.
- Best Value Source Selection: This approach considers price and factors like experience, past performance, and project-specific qualifications, making it popular for private projects. Though it often leads to higher initial costs, it prioritizes quality, reducing risks during construction and ensuring long-term project success.
- Direct Selection or Sole Source Procurement: The owner chooses a contractor without competitive bidding using this method. It allows for quick project starts with trusted contractors but can result in higher costs due to the lack of competition.
- Negotiated Procurement: The owner and contractor discuss terms directly, offering flexibility to adjust price, scope, and timelines.

Use of Digital Bidding and Construction Management Software
The construction industry uses technology more than ever, and digital bidding is a big part of this change.
Digital Bidding Software
Digital bidding lets contractors submit their project bids online instead of dealing with stacks of paper and in-person meetings. This method is faster and makes it easier for contractors and project owners to track everything related to a bid.
Digital bidding software often includes tools that help contractors calculate costs, organize bid documents, and manage deadlines—all in one place. This not only speeds up the process but also reduces mistakes.
Construction Management Software
In addition to bidding software, construction management software makes projects more manageable from start to finish. With construction management tools, contractors can plan their schedules, manage budgets, and track every part of a project in real-time.
Mistakes to Avoid in the Bidding Process
The construction industry’s bidding process requires careful planning and attention to detail. Even a small mistake can lead to big problems, such as financial losses or damaged reputation.
Here are some common mistakes contractors must avoid to increase their chances of winning bids and delivering successful projects.
Failing to Review
Not reviewing the bid package thoroughly is a major mistake. A bid package includes all project details, including scope, materials, and deadlines. Skipping a close review can lead to missing essential requirements, making the bid less competitive or disqualifying. Successful contractors carefully examine each detail to understand what the project owner expects.
Misestimating Costs
Accurate cost estimates are essential, as they set the bid amount and can impact a contractor’s profits. Overestimating costs can raise the bid, while underestimating can lead to financial losses if the project exceeds the budget.
To avoid these issues, contractors should use current data on material prices and labor rates and rely on estimating software.
Skipping Site Visits and Risk Assessments
Every site has unique challenges, such as difficult terrain or environmental concerns, that affect costs and timelines. By visiting the site, contractors gain insights that help them create a realistic and competitive bid. Site visits also allow them to address uncertainties and ask questions that improve accuracy.
Bid Without Expertise
Contractors may be tempted to expand into unfamiliar areas, but without the right skills, they risk underperforming. Partnering with experienced subcontractors allows contractors to undertake new projects without compromising quality or efficiency.
Conclusion
A structured, strategic approach to the bidding process is essential for success in the construction industry. Balancing competitive pricing with a commitment to quality and reliability is key to winning bids.
While a low price can be attractive, offering proven expertise and dependable service often makes a lasting impression. By following a well-planned bidding strategy, contractors can increase their chances of winning projects and delivering successful outcomes that lead to future opportunities.
