Mastering the bidding process is essential for construction companies to win projects and grow their business. This process consists of four key phases: bid solicitation, bid submission, bid selection, and contract formation.
The process begins when project owners solicit bids from contractors, typically by issuing an Invitation for Bid (IFB), a Request for Quote (RFQ), or a Request for Proposal (RFP). These documents outline project requirements and provide the information contractors need to prepare competitive bids.
During the bid submission phase, interested contractors compile comprehensive bid packages with detailed cost estimates, qualifications, project timelines, and other required documentation. General contractors often need to incorporate bids from various subcontractors to cover all aspects of the project.
After submission, the selection phase begins. Project owners evaluate bids based on multiple factors, such as price, contractor experience, proposed timelines, and other criteria from the bid solicitation. Many use a process called bid leveling to ensure fair comparisons by standardizing submission formats and content.
The final phase is contract formation. After selecting a winning bid, negotiations between the owner and chosen contractor finalize project terms and pricing, culminating in a formal contract that marks the official start of the project.
By understanding each step of this process, contractors can develop more compelling bids, improve their win rates, and set themselves up for project success. While the construction bidding process may initially seem daunting, experience and strategic preparation make it more manageable.
What Are the Different Types of Construction Bidding?

At EB3 Construction, we recognize that construction bidding comes in various forms, each with unique characteristics that can affect project outcomes. As general contractors, we’re experienced in the nuances of these bidding types and understand how they shape the competitive landscape.
Open tendering allows any qualified contractor to submit a bid, promoting fair competition and transparency. This method is especially beneficial for public projects, where accountability to taxpayers is crucial. We’ve participated in numerous open tenders for government contracts and can attest to the rigorous process involved in ensuring all bids are evaluated fairly.
Selective tendering, in contrast, invites only a predetermined group of contractors to bid. This approach balances competition and efficiency by narrowing the field to pre-qualified candidates. For private sector clients, selective tendering can effectively ensure bids come from contractors with proven experience in similar projects.
When specialized expertise is needed, negotiated tendering is often used. This involves selecting a single contractor and negotiating terms directly. We’ve been on both sides of negotiated tenders and find they are effective for complex projects where the scope may change during discussions. The key is maintaining open communication throughout the process to ensure alignment on project goals and constraints.
For clients with multiple similar projects planned over time, serial tendering offers unique advantages. This approach allows both owners and contractors to benefit from economies of scale while simplifying the overall bidding process. We’ve successfully executed serial tendering agreements that have resulted in long-term partnerships and improved efficiency across multiple job sites.
Each bidding type has its place in the construction industry, and choosing the right approach depends on project specifics, market conditions, and client priorities. At EB3 Construction, we tailor our bidding strategies to each unique situation, ensuring we put our best foot forward while meeting all compliance and transparency requirements.
How Do Project Delivery Methods Impact Construction Bids?
Project delivery methods significantly influence how construction bids are prepared, evaluated, and awarded. The selected delivery method shapes the entire bidding process, affecting how contractors approach pricing and how owners assess proposals. Let’s explore how some common delivery methods impact construction bidding:
Design-Bid-Build (DBB)
As the traditional approach, Design-Bid-Build clearly separates the design and construction phases. This impacts bidding in several ways:
- Contractors bid on fully completed designs, allowing for more accurate pricing
- The competitive bidding process often leads to lower initial costs for owners
- Bids focus primarily on construction costs, not design elements
- Less opportunity for contractor input on design can lead to more change orders later
Design-Build (DB)
The Design-Build method combines design and construction under one contract, changing the bidding dynamic:
- Bids include both design and construction costs
- Proposals often involve conceptual designs rather than finished plans
- Evaluation considers qualifications and approach in addition to price
- There may be fewer bidders due to the expanded scope, but this can result in more innovative solutions
Construction Manager at Risk (CMAR)
CMAR introduces a Guaranteed Maximum Price (GMP) from the construction manager, affecting bids as follows:
- The CM provides early cost estimates and a GMP before final design completion
- Subcontractor bids are often managed by the CM rather than the owner
- Risk allocation shifts, potentially affecting pricing strategies
- A collaborative approach may reduce the adversarial nature of traditional bidding
Job Order Contracting (JOC)
JOC uses preset costs in a Unit Price Book, creating a unique bidding scenario:
- Initial bids focus on markup percentages rather than project-specific costs
- Multiple projects can be executed under a single contract
- This method speeds up procurement, potentially reducing project delivery time by up to 25%
- Simplifies bidding for recurring or similar project types
The impact of delivery methods on construction bidding extends beyond just pricing. Each approach influences risk allocation, collaboration opportunities, and the overall relationship between owners, designers, and contractors. By understanding these nuances, project stakeholders can better navigate the bidding process and select the method that best aligns with their project goals and risk tolerance.
As the construction industry continues to evolve, new hybrid and innovative delivery methods may emerge, further shaping our approach to the crucial task of construction procurement. The key is to remain flexible and choose the method that offers the best balance of cost, quality, and risk management for each unique project.
What Criteria Should Be Used When Comparing Construction Bids?

When comparing construction bids, we establish clear evaluation criteria that extend beyond just considering the price. Our aim is to identify the contractor who can provide the best overall value and quality for the project. To achieve this, we use a comprehensive scoring matrix, assigning appropriate weight to several key factors:
- Technical experience: 25%
- Capabilities: 40%
- Data security: 10%
- Human resources: 10%
- Sustainability: 15%
This weighted approach enables us to evaluate bids holistically, considering both quantitative data and essential qualitative factors. We carefully review each proposal, examining critical elements such as:
- Insurance coverage
- Project timelines
- Scope of work understanding
- Risk management approaches
It’s essential that all bids include proper credentials, relevant certifications, and references from previous projects. We meticulously verify this information as part of our evaluation process.
Reference checks are a crucial step in our bid comparison. We conduct thorough checks to assess each contractor’s past performance, asking pointed questions like:
- Did you experience any significant delays with this contractor? If so, what caused them?
- How closely did the project adhere to the original budget? Were there any unexpected cost overruns?
- How did the contractor handle any disputes or challenges that arose during the project?
- Was communication clear, consistent, and responsive throughout the project lifecycle?
For public projects, we utilize bid tabulation to ensure transparency and fairness. This process involves compiling key details from all bids into a standardized format, allowing for easier comparison across proposals. Bid tabulation helps level the playing field and provides a clear audit trail for decision-making.
By implementing these comprehensive evaluation criteria and processes, we can confidently select the contractor best suited to deliver our project successfully, balancing cost considerations with critical qualitative factors.
Best Practices for Making Informed Construction Bid Decisions
At EB3 Construction, we’ve developed a structured approach for making informed decisions when evaluating construction bids. Our process involves more than just selecting the lowest price; it focuses on determining which contractor will provide the best overall value for a project. Here are some key best practices we follow:
Define Comprehensive Evaluation Criteria
We begin by establishing detailed criteria that align with each project’s unique requirements and priorities. This typically includes factors such as technical capabilities, relevant experience, project approach, schedule, and, of course, cost. Clearly defining these criteria upfront ensures a fair and thorough evaluation process.
Implement Weighted Scoring
Rather than treating all criteria equally, we use a weighted scoring system that assigns appropriate importance to different factors. In most cases, we allocate about 20% of the total score to cost considerations and 80% to technical capabilities and other non-price factors. This method allows us to identify the proposal that offers the best overall value, not just the lowest upfront price.
Conduct Detailed Proposal Reviews
Our team carefully reviews every aspect of submitted proposals, paying particular attention to the rationale behind pricing. We don’t simply accept the lowest bid at face value. Instead, we analyze cost breakdowns, assess whether estimates seem realistic, and look for any potential gaps or risks in the proposed approach.
Meet Contractors in Person
For significant projects, we always arrange face-to-face meetings with shortlisted contractors. These discussions allow us to clarify proposal details, discuss potential risks, and get a better sense of each team’s capabilities and approach. It’s often during these conversations that we uncover valuable insights that inform our final decision.
Consider Qualifications-Based Selection for Complex Projects
On particularly complex or specialized projects, we sometimes employ a qualifications-based selection (QBS) process. This approach prioritizes expertise and capabilities over initial cost estimates. We find QBS especially valuable when dealing with unique technical challenges or when innovation is a key project driver.
Maintain Transparency Throughout
Especially for public projects, we ensure full transparency in our bid evaluation process. This includes sharing bid tabulation documents and clearly communicating our selection criteria and decision-making rationale. Transparency not only fulfills legal requirements but also builds trust with contractors and stakeholders.
By adhering to these best practices, we consistently make well-informed bid decisions that lead to successful project outcomes. While the process requires more effort than simply choosing the lowest bid, we find it delivers far greater value in the long run.
Implementing a structured approach to bid evaluation allows us to select contractors who not only offer competitive pricing but also bring the right mix of expertise, innovation, and reliability to each project. This comprehensive view is essential for managing risks and ensuring projects are completed on time, within budget, and to the highest quality standards.
Conclusion: Maximizing Value Through Effective Bid Comparison

Understanding and effectively comparing construction bids is crucial for project success. By adopting a systematic approach to bid evaluation—establishing clear criteria, using weighted scoring matrices, conducting thorough reference checks, and considering delivery methods—we can select the contractor that best meets the project’s needs. It’s important to remember that the lowest bid isn’t always the best value; instead, focus on finding contractors with the right experience, capabilities, and understanding of project requirements.
Whether for public or private projects, transparent and fair bid comparison processes help build trust with contractors while minimizing the risk of disputes. Our goal is to ensure project objectives are met within budget and timeline constraints through comprehensive bid evaluation. By carefully assessing all aspects of submitted proposals, we maximize the chances of a successful partnership and project outcome.
Ultimately, effective bid comparison allows us to identify the contractor that offers the best overall value and fit for the specific project. This thoughtful approach to procurement sets the stage for smooth project execution and helps avoid potential issues. By investing in a robust evaluation process upfront, we benefit throughout the lifecycle of the construction project.
