Bid Readiness: Winning Your First Construction Contract

Who This Guide Is For

You've built the entire foundation. Corporation, CRA, WSIB, licences, insurance, safety, banking, accounting: all in place. You have a legal entity, government registrations, coverage, and operational infrastructure. Now comes the reason you did all of this: getting hired to build something.

This guide covers how construction companies actually win work in Ontario, from understanding how the market operates, to assembling a prequalification package, to submitting your first bid. This is where the seven guides before it converge into a single deliverable that puts revenue on your books.

How Construction Companies Get Work

Before diving into documents, you need to understand the channels. Construction work doesn't come from a storefront or a website the way retail businesses work. There are distinct paths, and each has different requirements:

Channel 1: Competitive Bidding (Public Sector)

Federal, provincial, and municipal governments, plus broader public sector entities (hospitals, universities, school boards, transit authorities) procure construction through formal competitive bidding processes.

How it works:

1. The owner publishes a tender (Request for Tender / Invitation to Tender) on a procurement platform
2. Contractors download the tender documents (drawings, specs, contract terms, bid form)
3. Contractors prepare and submit sealed bids by the deadline
4. Bids are opened publicly (or evaluated privately for RFPs)
5. The lowest compliant bidder wins (for tenders) or the best-value proponent wins (for RFPs)

Where to find public tenders:

• MERX (merx.com): the main Canadian public procurement platform. Federal, provincial, and many municipal tenders.
• Biddingo (biddingo.com): municipal and broader public sector tenders, especially in Ontario.
• Ontario Tenders Portal: provincial tenders
• GETS (Government Electronic Tendering System): Ontario broader public sector
• Individual municipal websites: many cities post tenders on their own procurement pages
• SACC (Standing Offers and Supply Arrangements): federal pre-qualified supplier lists

What you typically need to bid:

• Bid bond (5-10% of bid value), from your surety (Guide 5)
• Certificate of Insurance (CGL, minimum $2M-$5M)
• WSIB clearance certificate (current)
• Proof of licensing (ESA, TSSA, HCRA, if applicable)
• Company profile or prequalification package
• Completed bid form with pricing
• List of subcontractors (for some tenders)
• References / past project experience
• Agreement to bonding requirements (performance + payment bonds)

Channel 2: Prequalification + Invited Tender

Many larger owners, both public and private, maintain prequalified contractor lists. They evaluate contractors in advance, and only prequalified firms are invited to bid on specific projects.

How it works:

1. The owner issues a Request for Prequalification (RFPQ) or maintains an open prequalification process
2. You submit a prequalification package (the focus of this guide)
3. The owner evaluates your experience, financial capacity, safety record, insurance, bonding, and references
4. If approved, you're added to their qualified bidders list
5. When a project comes up, they invite you (and other prequalified firms) to bid

Common prequalification programs:

• Infrastructure Ontario (IO): major public infrastructure
• Metrolinx: transit construction
• Toronto Community Housing (TCHC)
• Major school boards, hospitals, universities
• Large private developers (Menkes, Tridel, EllisDon's sub prequalification)
• General contractors prequalifying their subcontractors

Prequalification is where you win or lose before pricing even enters the picture. A strong prequalification package opens doors. A weak one, or not having one at all, keeps you invisible.

Channel 3: Negotiated / Invited (Private Sector)

Private commercial and residential construction often works through relationships:

1. A GC is awarded a project
2. The GC invites subcontractors they know and trust to price specific scopes
3. You submit a quote
4. The GC selects based on price, relationship, track record, and availability
5. You negotiate terms and sign a subcontract

How to get invited:

• Build relationships with GCs in your market (networking, industry events, direct outreach)
• Get on GCs' approved subcontractor lists (many GCs have their own prequalification process)
• Deliver quality work on time. Word travels fast in construction, both good and bad.
• Respond quickly when a GC calls for pricing. The sub who prices fastest often gets the first look.

Channel 4: Direct Client (Residential / Small Commercial)

For residential renovation, small commercial fit-ups, and direct-to-owner work:

• Homeowners and small business owners find you through referrals, Google, social media, or industry directories
• You visit the site, assess the scope, and provide a written quote
• The client selects based on price, reputation, and trust
• You sign a contract and perform the work

What clients look for:

• Portfolio of past work (photos, descriptions)
• References from past clients
• Insurance certificate
• WSIB clearance
• Licensing (ESA number, Toronto renovator licence, if applicable)
• A professional, detailed written quote
• A clear contract with scope, timeline, payment terms, and warranty

The Prequalification Package: Your Company's Resume

This is the master document that introduces your company to prospective clients, GCs, and prequalification programs. A complete package contains everything a project owner needs to evaluate whether they want to do business with you.

What Goes In It

1. Company Profile (2-4 pages)

A professional document covering:

• Company overview: Legal name, corporation number, date of incorporation, BN, HST number, WSIB account number
• Business description: What you do, what types of projects you specialize in, your service area
• Corporate structure: Directors, officers, key personnel
• History and experience: Years in business (include your personal experience if the company is new), growth trajectory, key milestones
• Mission and values: Brief statement of what drives the company (quality, safety, integrity; keep it genuine, not generic)
• Differentiators: What sets you apart (specialized equipment, unique certifications, niche expertise, safety record, technology adoption)
• Contact information: Office address, phone, email, website

2. Key Personnel Resumes

Individual resumes for:

• Company principal(s) / director(s)
• Project managers / superintendents
• Site supervisors
• Key tradespeople (journeypersons with specialized certifications)

Each resume should show:

• Name, title, years of experience
• Relevant certifications (C of Q number, Working at Heights, First Aid, COR auditor, etc.)
• Project experience (project name, owner, GC, scope, value, role)
• Education and training

For a new company, your personal track record matters most. If you spent 15 years as a superintendent for a large electrical contractor before starting your own company, that experience is your strongest asset. Frame the resume around your career, not just the company's history.

3. Project Experience / References

A list of 3-10 relevant past projects, each showing:

If your company is new but you have personal project experience from previous employers, list those projects with a note like "Performed while employed as Senior Electrician at XYZ Electric Ltd." Most evaluators care about your personal capability, not just your corporate history.

Choose your references carefully. Call them first. Tell them someone may be reaching out. Make sure they'll say positive things. A bad reference is worse than no reference.

4. Safety Record and Program

• WSIB experience rating (if you have one; new companies won't have one yet)
• Claims history (ideally zero; state this explicitly if true)
• COR certification (Certificate of Recognition), if you have it (a significant competitive advantage, but new companies typically don't have this yet; it takes 1-2 years to achieve)
• Safety training summary: List of certifications held by your team (Working at Heights, First Aid/CPR, WHMIS, JHSC Certification, trade-specific safety training)
• Health & Safety policy summary: One-paragraph description of your safety program
• Lost-time injury frequency rate (if you have enough history to calculate one)
• Safety awards or recognition (if any)

For a brand-new company: State that you have zero claims history, describe your safety program, list your training certifications, and emphasize your commitment to safety. A clean slate is actually an advantage. Evaluators would rather see zero history than a history of incidents.

5. Insurance and Bonding

• CGL: Carrier name, policy number, limits ($X per occurrence / $X aggregate), expiry date
• Professional liability (if applicable): Same details
• Commercial auto: Confirmation of coverage
• Equipment insurance: Confirmation of coverage
• Bonding: Surety company name, single-project limit, aggregate limit, contact person
• WSIB: Account number, clearance certificate status

Attach copies of:

• Current Certificate of Insurance
• Current WSIB Clearance Certificate
• Letter from surety confirming bonding capacity (if applicable)

6. Trade Licences and Certifications

• ESA Electrical Contractor Licence number (if applicable)
• TSSA Licence number (if applicable)
• HCRA Builder Licence number (if applicable)
• Toronto Renovator Licence number (if applicable)
• Certificates of Qualification for key tradespeople (list name, trade, C of Q number)
• Any other relevant certifications (environmental, specialized equipment operation, etc.)

7. Equipment List

A list of major equipment owned or available:

This demonstrates your capacity to self-perform work without relying entirely on rental equipment.

8. Financial Information (When Required)

Some prequalification programs require:

• Reviewed or audited financial statements (last 1-3 years)
• Bank reference letter
• Credit references (suppliers, subcontractors)
• Bonding letter (confirming capacity)

New companies without financial history: Provide a bank reference letter, a personal financial statement from the principal, and any available interim financial statements. Be upfront about being a new company and lean on personal experience and financial stability.

9. Corporate Documents (When Required)

• Certificate of Incorporation
• Articles of Incorporation
• Business Number confirmation
• HST registration confirmation
• WSIB registration confirmation

Making It Professional

Presentation Matters

Your prequalification package is your first impression. In a stack of 20 submissions, evaluators spend 5-10 minutes on each. Make yours easy to read and professional:

• Consistent formatting. Same fonts, headers, and layout throughout.
• Company branding. Logo, brand colours, contact info on every page.
• Table of contents. For packages over 10 pages.
• Tab dividers. If submitting hard copies (some still require them).
• PDF format. For electronic submissions, compile everything into a single, bookmarked PDF.
• Page numbers. Always.
• File naming convention. [CompanyName]_Prequalification_[Year].pdf

Common Evaluation Criteria

When evaluators score your prequalification package, they typically weight these categories:

The #1 reason prequalification packages get rejected: missing information. If the RFPQ asks for 12 items and you submit 10, you may be disqualified on completeness alone. Read the requirements obsessively and submit everything they ask for.

Your First Bid: Step by Step

Once you're prequalified (or bidding on an open tender), here's the process:

Step 1: Find the Opportunity

Where to look:

• Bid platforms: MERX, Biddingo, Ontario Tenders Portal, municipal procurement pages
• GC invitations: GCs you've built relationships with will call or email you directly
• Bid notification services: Some platforms offer alerts based on your trade, location, and project size
• Industry networks: Construction associations (OGCA, OCA, local construction associations) often circulate bid opportunities to members
• Daily commercial news: Sources like Daily Commercial News (DCN) publish upcoming projects and tender calls

Step 2: Evaluate the Opportunity (Bid/No-Bid Decision)

Not every tender is worth bidding on. Before investing time in pricing, evaluate:

Can you do this work?

• Does the scope match your capabilities?
• Do you have (or can you get) the required licences and certifications?
• Do you have capacity; can you staff this project without overextending your current commitments?
• Does the timeline work; can you meet the start and completion dates?

Can you win?

• Is the project in your sweet spot (type, size, location)?
• Do you have relevant experience that gives you credibility?
• Is the evaluation based purely on price (lowest wins) or on value/qualifications?
• How many other contractors are likely bidding? (More than 6-8 bidders = very competitive)
• Do you have a relationship with the owner or GC?

Should you win?

• Are the contract terms reasonable? (Watch for onerous liquidated damages, unreasonable insurance requirements, unrealistic schedules)
• Is the payment structure workable? (Long payment terms, excessive holdback, or milestone-based billing can strain cash flow)
• Is the project properly funded? (Government projects are generally safe. For private projects, verify the owner can pay.)
• Is the profit margin worth the risk?

A disciplined bid/no-bid process saves you from two things: wasting time on bids you won't win, and winning work that loses money.

Step 3: Review the Tender Documents

Read everything. The full set typically includes:

• Invitation to Tender / Instructions to Bidders. Deadlines, submission requirements, evaluation process.
• Agreement (contract form). The contract you'll sign if you win.
• General conditions. Standard contractual provisions (CCDC 2, OAA 600, or owner-specific).
• Supplementary conditions. Project-specific modifications to the general conditions.
• Drawings. Architectural, structural, mechanical, electrical: the visual representation of the work.
• Specifications. Written technical requirements for materials, equipment, installation methods, and quality standards.
• Bid form. The specific format for your pricing submission.
• Bonding and insurance requirements. What's required at bid stage and at contract stage.
• Addenda. Any revisions or clarifications issued after the original tender documents (ALWAYS check for addenda; missing an addendum can disqualify your bid).

Step 4: Prepare Your Estimate

This is the core skill of construction bidding: accurately estimating the cost of performing the work. A full estimating tutorial is beyond this guide, but the fundamentals:

Quantity takeoff:

• Measure every item of work from the drawings and specifications
• Count, measure, or calculate quantities (linear metres of pipe, square metres of drywall, number of fixtures, cubic metres of concrete)
• Use digital takeoff software (Bluebeam, PlanSwift, On-Screen Takeoff) or manual methods

Pricing:

• Labour: Hours to perform each task x hourly cost (wage + burden, including CPP, EI, WSIB, benefits, and vacation pay). Labour burden in Ontario construction adds 25-40% above the base wage.
• Materials: Quantity x unit cost. Get supplier quotes for major items; don't guess.
• Equipment: Owned equipment hours x internal rate, or rental quotes for equipment you'll need to rent.
• Subcontractors: Get quotes from your subs for scopes you're not self-performing. Get at least 2-3 quotes per scope to ensure competitiveness.

Markups:

• Overhead: Your fixed costs that aren't directly attributable to one project (office, insurance, vehicles, admin salaries, software, accounting). Typically 10-20% of direct costs.
• Profit: Your margin. In competitive bidding, 5-10% is typical for construction. On negotiated work, 10-15% or more.
• Contingency: A reserve for unknowns and scope gaps. 3-5% on well-defined projects, 10%+ on renovation/demolition where surprises are common.

Your bid price = Labour + Materials + Equipment + Subcontractors + Overhead + Profit + Contingency

Step 5: Assemble Your Bid Submission

Typical bid submission includes:

1. Bid form. Completed and signed, with your total bid price and any required unit prices or alternates.
2. Bid bond. 10% of bid value (from your surety).
3. Agreement to bond. Confirmation that your surety will issue performance and payment bonds if you're awarded.
4. Certificate of Insurance. Current, showing required limits.
5. WSIB clearance certificate. Current.
6. Consent of surety. Letter from your surety confirming bonding capacity.
7. List of subcontractors. Some bids require you to name your major subs.
8. Addenda acknowledgment. Confirming you received and priced all addenda.
9. Corporate profile. If required by the bid documents.
10. Any other documents specified in the Instructions to Bidders

Check the submission requirements three times. Read the Instructions to Bidders, then read them again, then have someone else read them. Missing a single required document or form can get you disqualified. A misplaced decimal point in your bid price cannot be corrected after submission.

Step 6: Submit Before the Deadline

• Electronic submissions: Upload to the specified platform before the deadline. Don't wait until the last 10 minutes. Platform crashes and upload errors happen at deadline time.
• Hard copy submissions: Deliver to the specified address in a sealed envelope with the project name and your company name on the outside. Arrive early. Late bids are rejected. One minute late is still late.

Step 7: After Submission

If you're the low bidder (tenders):

• The owner reviews your bid for compliance
• They may ask for clarification on specific items (respond immediately and precisely)
• They issue a formal award letter / Notice of Award
• You sign the contract and provide performance and payment bonds within the specified timeframe (typically 10-15 business days)
• Mobilize for construction

If you're not the low bidder:

• Many public owners will tell you the winning bid price (public bid openings)
• Analyze how your price compared. Were you high on labour? Materials? Subs?
• Every bid you lose is data for the next one
• Maintain the relationship. Follow up professionally, express interest in future opportunities.

The Ongoing Bid Machine

Bidding is a continuous process that runs in parallel with your active projects:

Keep Everything Current

Every document in your prequalification package has an expiry date or an update trigger:

If your WSIB clearance expires between bid submission and award, you can lose the contract. If your insurance lapses, same result. Keeping everything current is revenue protection.

Building Your Reputation

Beyond the documents, winning work in construction is fundamentally about reputation. Ontario construction is a smaller world than people think. GCs talk to each other. Project managers move between companies and bring their preferred subcontractors with them. Owners remember who delivered and who didn't.

The things that build your reputation:

1. Deliver on time. Every time. If you're going to be late, communicate it early and honestly.
2. Deliver on budget. Don't nickel-and-dime with change orders for things that were clearly in your scope. Save change orders for genuine scope changes.
3. Quality work. Deficiency lists should be short. Punch lists should close fast. Warranty callbacks should be rare.
4. Clean safety record. Zero incidents. No MOL orders. No stop-work situations. GCs notice which subs slow down their projects with safety problems.
5. Pay your subs and suppliers. Word gets around if you're slow to pay. Good subs won't work with you, and material suppliers will put you on COD terms.
6. Professional communication. Return calls promptly. Submit RFIs clearly. Attend coordination meetings prepared. Document everything.
7. Solve problems, don't create them. When something goes wrong on site (it always does), be the contractor who offers solutions instead of finger-pointing.

None of this shows up in a prequalification package, but it's what gets you invited back. The best subcontractors in Ontario rarely bid on open tenders. They're always busy because GCs call them first.

Common Mistakes to Avoid

1. Bidding on everything. Bid selectively on projects you can realistically win and profitably execute. Every bid takes 10-40 hours of estimating time. That time has a cost. A 10% win rate on well-targeted bids is better than a 2% win rate on everything.

2. Submitting a generic prequalification package. Tailor your submission to each opportunity. If the RFPQ emphasizes safety, lead with your safety record. If they emphasize experience with similar projects, lead with relevant project sheets. One-size-fits-all packages score lower.

3. Forgetting to check for addenda. Addenda are issued after the original tender documents to clarify or change the requirements. If you price the original documents without incorporating Addendum #3 (which changed the mechanical specs), your bid is wrong and may be disqualified if you didn't acknowledge the addendum.

4. Leaving out required documents. If the bid instructions list 8 required attachments and you submit 7, you're out. Read the requirements. Make a checklist. Check it twice.

5. Submitting at the last minute. Electronic platforms crash. Traffic happens. Couriers get lost. Submit at least 2 hours before the deadline. There is no prize for submitting last, and there is no appeal for submitting late.

6. Not following up after losing. Most public owners will debrief you on request. Ask what you scored, where you lost points, and what you could improve. This information is gold for future bids. Some GCs will do the same informally.

7. Underbidding to win your first project. Going low to build your track record is tempting, but a project that loses money is worse than no project. You can't build a reputation on work that bankrupts you. Bid your real costs plus a reasonable margin. If you don't win, you'll win the next one.

8. Not having your documents ready before the opportunity appears. Tender periods are short, typically 2-4 weeks. If you're scrambling to get your WSIB clearance, chase your broker for a COI, and write a company profile from scratch, you won't make the deadline. Be ready before opportunities arrive.

What Happens Next

You've completed the "Idea to First Bid" journey:

From here, it's execution. Win the project. Deliver it. Get paid. Build your track record. Win the next one, bigger. Every project you complete makes the next bid stronger: more experience, better references, higher bonding capacity, cleaner safety record.

There's one more guide in this series:
