TL;DR
A contractor prequalification checklist covers the documents, safety metrics, insurance certificates, written programs, and financial records that general contractors and owners require before allowing subcontractors to bid. Roughly 74% of GCs require prequalification for projects over $500K, and 34% of rejections come from missing documents or blank fields. This guide defines every item you will encounter, explains the thresholds that matter, and identifies the mistakes that get contractors disqualified.
What Is a Contractor Prequalification Checklist?
A contractor prequalification checklist is the organized set of criteria that general contractors, project owners, and hiring clients use to evaluate a subcontractor’s safety record, financial health, insurance coverage, and operational capability before that contractor is invited to bid on work.
For the contractor being evaluated, the checklist functions as a preparation roadmap. For the GC or owner running the evaluation, it is a risk management tool.
The stakes are concrete. Contractors without completed prequalification profiles are invisible to the majority of general contractors during bid solicitation. An EMR above 1.0 disqualifies contractors from an estimated 58% of public bid opportunities. And losing a single mid-sized contract over a failed prequalification submission can mean $50,000 to $250,000 in lost revenue.
If you are a contractor preparing for prequalification on ISNetworld, Avetta, or a GC’s internal questionnaire, this checklist covers every category you will need. If you are a GC building or refining your own screening process, the benchmarks and scoring frameworks below will help you set meaningful thresholds.

Quick Takeaway: What Belongs on a Contractor Prequalification Checklist?
A standard contractor prequalification checklist requires 5 core document categories to pass General Contractor (GC) and third-party platform (ISNetworld, Avetta) vetting:
Safety Metrics: EMR (3-year history, target ≤ 1.0), TRIR (target < 2.4), DART rate, and OSHA 300/300A logs.
Insurance & Bonding: ACORD Certificate of Insurance (General Liability, Workers’ Comp, Auto), Additional Insured Endorsement, Waiver of Subrogation, and Surety Bonding Capacity Letter.
Written Safety Programs: Company Safety Manual and trade-specific RAVS programs (e.g., Fall Protection, LOTO, HazCom, Confined Space).
Financial Documentation: 2–3 years of audited or reviewed financial statements, W-9/FEIN verification, bank references, and credit scores.
Past Performance & Credentials: 3–5 similar project references, OSHA 10/30 cards, competent person designations, and active trade licenses.
Pro Tip: Missing documents or blank form fields account for roughly 34% of all automatic prequalification rejections.
How Contractor Prequalification Works
Prequalification happens before bid day. It is a screening gate, not part of the bid evaluation itself. Contractors who do not clear prequalification never get the chance to compete on price or qualifications.
The Two Paths
Third-party platforms like ISNetworld, Avetta, and Veriforce are the dominant mechanism in construction, oil and gas, utilities, and energy. These platforms collect and verify contractor safety data, insurance documentation, and compliance records. Each platform scores contractors differently (letter grades, traffic-light flags, pass/fail), and each hiring client within a platform can impose its own additional requirements.
GC-specific questionnaires are standalone prequalification packets sent directly to subcontractors. They cover the same categories but lack the ongoing verification and scoring that platforms provide.
It Is Not a One-Time Exercise
Practitioners on forums and review sites consistently emphasize that prequalification is ongoing. Insurance certificates expire. OSHA logs need annual updates. Training records change as workers come and go. One Capterra reviewer describing ISNetworld noted that one missed document expiration can drop your grade and pull you off an approved vendor list before you even realize it happened.
The contractor prequalification checklist below is organized by category. Each entry includes a plain-language definition, why it matters for prequalification, and the thresholds or standards that commonly apply.
Prequalification vs. Post-Qualification: Key Differences
Understanding where prequalification sits in the procurement cycle prevents costly wasted effort during bidding.
Feature | Prequalification (Pre-Bid) | Post-Qualification (Post-Bid) |
Timing | Completed weeks or months before bid submission | Executed after low-bid selection, prior to contract award |
Primary Goal | Screening for baseline safety, financial, and operational risk | Verifying capacity specific to the awarded contract scope |
Cost to Contractor | Paid upfront (annual platform fees or preparation time) | Low (project-specific verification) |
Public vs. Private | Standard across commercial, energy, and public sectors | More common in public sector low-bid awards |
Impact of Failure | Disqualification from receiving the RFP or bidding | Rejection of bid; award passed to next lowest bidder |
Company and Legal Information
Every prequalification submission starts with basic business identification. This section seems straightforward, but incomplete or inconsistent entries are a common rejection trigger.
Company Profile / Business Information
Your legal business name, physical address, mailing address, key contact names and titles, phone numbers, and email addresses. Platforms cross-reference this against state registration databases, so discrepancies between your platform profile and your state filings will create problems.
NAICS Code
The North American Industry Classification System code that identifies your trade or business type. Prequalification platforms use NAICS codes to match you with relevant hiring clients and to determine which safety programs you must provide. Selecting the wrong NAICS code can trigger unnecessary program requirements or, worse, cause you to miss opportunities in your actual trade.
DUNS Number
A unique nine-digit identifier assigned by Dun & Bradstreet. Required for federal contracting and used by many GCs and platforms to pull your business credit history. If you do not have one, getting it takes several weeks, so do not wait until a project is on the table.
Federal Employer Identification Number (FEIN)
Your IRS-issued tax identification number. Required on virtually every prequalification form and used to verify your business is legitimate and in good standing.
Years in Business and Ownership Structure
Most GCs want to see a minimum track record (often three to five years) and want to understand whether the company is a sole proprietorship, LLC, partnership, or corporation. Ownership structure can affect bonding capacity and insurance requirements.
Safety Performance Metrics
Safety performance is the most heavily weighted category in nearly every prequalification scoring model, typically accounting for 25% to 30% of the total score. This is where contractors pass or fail.
EMR (Experience Modification Rate)
The EMR is a multiplier calculated by the National Council on Compensation Insurance (NCCI) or your state’s equivalent rating bureau. It compares your company’s actual workers’ compensation claims history to the expected claims for businesses of your size and trade.
An EMR of 1.0 is average by design. Below 1.0 means fewer or less severe claims than expected. Above 1.0 means worse than expected.
Prequalification thresholds: Most GCs set a hard ceiling between 1.0 and 1.2. An EMR above 1.2 is a common automatic disqualifier. Data from constructionbids.ai indicates that improving your EMR from 1.05 to 0.85 can add 8 to 15 points to your prequalification score, potentially moving you from conditional approval to full approval.
Platforms typically require three to five years of EMR history. For a deeper explanation of how experience rating works and how to improve it, see this guide on understanding experience rating.
TRIR (Total Recordable Incident Rate)
TRIR measures the number of OSHA-recordable injuries and illnesses per 100 full-time equivalent workers per year. The formula is: (Number of recordable cases x 200,000) / Total hours worked.
The Bureau of Labor Statistics reported the construction industry average TRIR at 2.4 per 100 FTE in 2024. A TRIR below 2.0 is generally considered good for construction. Many GCs set prequalification thresholds between 1.0 and 2.0 depending on the project risk level.
Like EMR, platforms require three to five trailing years of TRIR data.
DART Rate
Days Away, Restricted, or Transferred. DART narrows the TRIR calculation to only those incidents that resulted in lost workdays, restricted duty, or job transfers. It provides a severity measure that TRIR alone does not capture. GCs review DART alongside TRIR to get a more complete picture of your safety performance.
LTIR (Lost Time Incident Rate)
An older metric that counts only cases involving days away from work. Some GCs and platforms still request it, particularly in oil and gas and heavy industrial settings.
OSHA 300 Log / 300A Summary
The OSHA 300 Log is your running record of workplace injuries and illnesses throughout the year. The 300A is the annual summary that must be posted at your workplace from February 1 through April 30. Prequalification submissions require three trailing years of OSHA 300A summaries. For a detailed breakdown of how these forms work together, see this guide to OSHA 300, 301, and 300A forms.
Missing or incomplete OSHA logs are one of the fastest ways to get a prequalification submission rejected. Platform reviewers check that your recorded incident numbers match the rates you reported.
Insurance and Bonding
Insurance documentation is the second pillar of any contractor prequalification checklist. Hiring clients need proof that you carry adequate coverage before you set foot on their project.
Certificate of Insurance (COI)
A standardized document (typically an ACORD form) issued by your insurance carrier that summarizes your active policies, coverage limits, and effective dates. Avetta, ISNetworld, and most GCs require current COIs uploaded to the platform or submitted with bid packages.
The most common coverage types required include:
Commercial General Liability (CGL): Covers third-party bodily injury and property damage. Minimum limits of $1 million per occurrence and $2 million aggregate are standard, though many owners and GCs require higher.
Workers’ Compensation: Statutory limits as required by your state. No exceptions.
Employer’s Liability: Usually included with workers’ comp. Common minimums are $500,000 to $1 million.
Automobile Liability: Covers vehicles used for business. Minimums typically $1 million combined single limit.
Additional Insured Endorsement
An endorsement added to your CGL policy that extends coverage to the hiring client (the GC or owner). This is not optional on most projects. The endorsement must name the specific entity, and the COI must reference it. Getting this wrong is a frequent cause of prequalification delays.
Waiver of Subrogation
A waiver that prevents your insurance carrier from seeking reimbursement from the hiring client after paying a claim. Most GCs require waiver of subrogation endorsements on both your CGL and workers’ compensation policies.
Umbrella / Excess Liability
Additional liability coverage above your primary policy limits. Large commercial and industrial projects commonly require $5 million to $10 million in umbrella coverage. Smaller contractors often struggle here because umbrella policies are expensive relative to revenue.
Professional Liability
Required when the contractor provides design, engineering, or consulting services. Not universal but increasingly requested in design-build and engineering-procure-construct projects.
Pollution Liability
Required for environmental, demolition, abatement, and remediation work. Some hiring clients require it for any work involving chemicals or potential soil/groundwater contamination.
Bonding Capacity
Your ability to secure surety bonds (bid bonds, performance bonds, payment bonds). Bonding capacity reflects your financial strength and is typically expressed as a single-project limit and an aggregate limit. GCs evaluating your prequalification want to see that your bonding capacity can handle the size of their projects.
EMR Letter
A letter from your insurance carrier or NCCI confirming your current and historical EMR. This is the verification document behind the EMR number you report. If your EMR letter and your self-reported EMR do not match, expect a rejection.
Written Safety Programs
Written safety programs are where prequalification gets hard. It is not enough to have documents on file. Platforms like ISNetworld and Avetta evaluate whether your programs address the actual hazards of your registered work type, cite the correct OSHA standards, name your company specifically, and include required elements like training frequencies and documentation forms.
This is the single biggest failure point in contractor prequalification. Generic templates downloaded from the internet will not pass.
If your written programs need work, ESR’s safety program development services can build or rewrite programs that meet platform requirements and OSHA standards.
Safety Manual / Written Safety Program
Your company’s master safety document. It should cover your overall safety policy, management commitment, employee responsibilities, and the specific programs applicable to your operations. For guidance on whether your safety manual is OSHA compliant, ESR has a detailed assessment resource.
Site-Specific Safety Plan (SSSP)
A project-level document that addresses the unique hazards, controls, emergency procedures, and responsibilities for a specific jobsite. Many owners and GCs require an SSSP before mobilization. It is distinct from your company safety manual. For a breakdown of what to include in a site-specific safety plan, see ESR’s detailed guide.
Activity Hazard Analysis (AHA) / Job Hazard Analysis (JHA)
A task-level document that identifies hazards associated with a specific work activity and defines the controls to mitigate each hazard. AHAs are required on federal projects and increasingly expected on commercial work. The difference between an AHA and a JHA is largely contextual, but both serve the same purpose.
Fall Protection Plan
Required under OSHA 29 CFR 1926 Subpart M whenever workers are exposed to fall hazards of six feet or more (in construction). The plan must describe the fall protection methods used, rescue procedures, and training requirements. Fall protection violations are consistently the most cited OSHA standard, making this a high-scrutiny document during prequalification.
Lockout/Tagout (LOTO) Program
Required under OSHA 29 CFR 1910.147 for controlling hazardous energy during maintenance and servicing of equipment. The program must include machine-specific procedures, not just a generic policy. Platform reviewers check for equipment-specific lockout procedures and evidence of annual inspections.
Confined Space Entry Program
Required under OSHA 29 CFR 1910.146 (general industry) and 29 CFR 1926 Subpart AA (construction). The most common RAVS rejection in this category is a missing rescue plan. If your program describes permit-required confined space entry, it must address how rescue will be performed, whether by internal rescue team or external service.
Hazard Communication / SDS Program
Required under OSHA’s Hazard Communication Standard (29 CFR 1910.1200). Must include a written program, a chemical inventory, Safety Data Sheets for every hazardous chemical on site, and a description of how employees are trained. ESR’s guide on OSHA hazard communication standards covers the specifics.
Respiratory Protection Program
Required under OSHA 29 CFR 1910.134 whenever respirators are used or required. Must include medical evaluation procedures, fit testing protocols, respirator selection criteria, and training requirements. An incomplete respiratory program is a frequent prequalification rejection.
Drug and Alcohol Policy
Required by most hiring clients and virtually all prequalification platforms. The policy must define testing circumstances (pre-employment, random, post-incident, reasonable suspicion), testing methods, consequences, and employee assistance provisions.
Emergency Action Plan (EAP)
Required under OSHA 29 CFR 1910.38. Must cover evacuation procedures, alarm systems, emergency contacts, and employee training. For a complete overview of OSHA emergency action plan requirements, ESR has a checklist-format guide.
ISNetworld may require anywhere from 8 to 40 safety programs to be uploaded and reviewed, depending on your registered trades and the specific hiring clients you are trying to qualify with.
Training Records and Certifications
Prequalification platforms and GCs verify that your workforce holds the certifications and training required for the work you perform.
OSHA 10-Hour / 30-Hour
OSHA Outreach Training Program cards. OSHA 10 is required for construction workers on many projects. OSHA 30 is typically required for supervisors and foremen. Some states (New York, Connecticut, Massachusetts, Nevada, Missouri) mandate OSHA 10 or 30 by law. Many GCs require it contractually even where no state mandate exists.
Competent Person Designation
OSHA requires a “competent person” for specific hazards including scaffolding, excavation, fall protection, and steel erection. A competent person must be able to identify existing and predictable hazards and have the authority to take corrective action. Prequalification reviewers look for documentation of competent person training and written designations. ESR’s resource on OSHA competent person training requirements breaks this down further.
NCCER Certification
National Center for Construction Education and Research credentials validate craft skills in specific trades. While not universally required for prequalification, NCCER certifications strengthen a contractor’s profile, particularly for electrical, pipefitting, ironwork, and heavy equipment operations.
Equipment-Specific Training
Documentation that operators of forklifts, aerial lifts, cranes, and other powered equipment have been trained and evaluated per OSHA requirements. Missing operator training records are a common deficiency that can hold up an otherwise complete prequalification package.
Prequalification Platforms
Understanding how the major platforms work is essential to completing your contractor prequalification checklist efficiently.
ISNetworld (ISN)
The largest U.S. contractor prequalification network, with over 75,000 contractor members. ISNetworld collects safety programs, insurance documents, OSHA logs, and training records. It uses letter grades (A through F) and a proprietary grading algorithm that weighs different components based on each hiring client’s requirements.
The hidden complexity: ISNetworld uses per-operator branching, meaning the same contractor signed up under one hiring client may see different required sections, different completeness scores, and different grades than they see under another hiring client on the same platform. You can pass on one operator’s account while quietly failing on another. No other ranking page for contractor prequalification checklist terms explains this, but it is one of the most frustrating realities contractors face.
Annual fees start at $950 to $1,050 per year for micro-contractors and scale with workforce size. For help with ISNetworld setup and compliance, ESR offers consulting services that cover account configuration, program uploads, and RAVS preparation.
RAVS (Review and Verification Services)
ISNetworld’s document review process. When you upload written safety programs, RAVS reviewers evaluate them against structural criteria specific to your registered trades. The feedback is not always clear. A contractor may know something was rejected but still not understand exactly what needs to change, leading to multiple rounds of revisions. Practitioners on Capterra describe this as one of ISNetworld’s most frustrating aspects, with one reviewer calling it “a necessary evil” and noting that ISN and hiring clients sometimes point fingers at each other over requirements.
For detailed help navigating this process, see ESR’s guide on ISNetworld RAVS help for contractors.
Avetta
The second major prequalification platform. Avetta uses a traffic-light flag system (green, amber, red) rather than letter grades. Its review process specifically checks whether uploaded safety programs address the actual hazards of the contractor’s registered work type, not just whether a document exists. Generic or template programs that lack company-specific procedures, supervisor names, and site-specific hazard controls score poorly.
For Avetta-specific guidance, ESR provides Avetta compliance support.
Veriforce
The third major platform, particularly common in pipeline, oil and gas, and utility sectors. Veriforce also collects safety data, insurance, and training documentation but has its own interface and requirements.
No Automatic Reciprocity
A critical point that catches many contractors off guard: there is no automatic reciprocity between platforms. A clean ISNetworld profile does not substitute for Avetta registration, and vice versa. If a hiring client uses Avetta, you must register on Avetta. Forum users note that maintaining multiple platforms can represent a $20,000 or more annual investment for smaller companies, with duplicative information still required in separate bid packages.
Management System Questionnaire (MSQ)
A structured questionnaire within some prequalification platforms that evaluates how your company manages safety at a systems level. Questions cover management commitment, employee involvement, hazard identification processes, training systems, and continuous improvement. The MSQ goes beyond asking whether you have a program. It asks how your program functions in practice.
Hiring Client
The term platforms use for the GC, owner, or operator that requires contractors to be prequalified. Each hiring client on a platform can set its own requirements, thresholds, and required programs, which is why the same contractor can be approved for one hiring client and deficient for another on the same platform.
Scoring and Evaluation
Prequalification Grade
The overall score or rating a platform assigns based on your submitted documentation, safety metrics, insurance compliance, and questionnaire responses. On ISNetworld, this appears as a letter grade (A through F). On Avetta, it appears as a color flag. GCs use these grades to make quick pass/fail decisions.
Risk Tier
Many GCs and some platforms categorize contractors into tiers. A common model uses three tiers: Tier 1 (fully approved, no restrictions), Tier 2 (approved with conditions), and Tier 3 (conditional, restricted to lower-risk work or requiring additional oversight). Moving from Tier 3 to Tier 2 can significantly expand the number of projects you are eligible to bid.
Conditional Approval
A status where the contractor has met some but not all prequalification requirements. Conditional approval may allow limited work while deficiencies are corrected, or it may simply mean the contractor must resolve specific issues before full approval is granted.
Corrective Action Plan
A documented plan that describes how you will address identified deficiencies. If your EMR exceeds the threshold, for example, a corrective action plan outlining the specific steps you are taking to reduce your incident rates can sometimes keep you in contention when a flat rejection might otherwise apply.
General Contractor Prequalification Scoring Matrix
General contractors and owners evaluate prequalification packets using weighted risk matrices. While exact percentages vary by owner, standard commercial evaluation frameworks prioritize metrics using the following weight distribution:
Evaluation Category | Typical Weight | Primary Target Thresholds | Common Rejection Triggers |
Safety Performance | 30% – 35% | EMR ≤ 1.0; TRIR < 2.4; Zero fatalities | EMR > 1.2; Missing OSHA 300A logs |
Financial Health | 25% – 30% | Current Ratio ≥ 1.2; Working Capital > 10% of project value | Unaudited statements; active tax liens |
Insurance Compliance | 20% | $1M–$5M CGL; Active Workers’ Comp | Missing Additional Insured / Waiver endorsements |
Project Experience | 15% | 3+ projects of similar dollar size & scope | Incomplete reference contact details |
Written Safety Programs | 10% | OSHA/RAVS compliant trade programs | Generic internet templates; unaddressed hazards |
Prequalification Questionnaire (PQQ)
The standardized form (platform-based or GC-issued) that collects all of the information described in this contractor prequalification checklist. PQQs are static snapshots. Their limitation is that they can become outdated the moment they are submitted, which is why ongoing verification matters.
Financial Stability
Financial capacity typically carries 20% to 25% of the total prequalification score. GCs want assurance that you can fund operations, manage cash flow during payment delays, and absorb unexpected project costs without defaulting.
Common documents requested include:
Audited or reviewed financial statements (two to three trailing years)
Bank reference letters
Credit reports (Dun & Bradstreet or equivalent)
Evidence of bonding capacity (surety letter)
Current accounts receivable and payable aging
Revenue by year (to demonstrate growth trajectory or stability)
Contractors often underestimate how closely GCs examine financial statements during prequalification. A contractor with excellent safety numbers but weak financials can still be disqualified, particularly on larger projects where subcontractor default risk directly threatens the GC’s schedule and budget.
Project Experience and References
This section evaluates whether you have successfully completed work similar in scope, complexity, and size to the project you want to bid. Typical requirements include:
Three to five completed projects of comparable scope and value
Client references with contact information
On-time and on-budget completion history
Evidence of work in the specific trade or sector
Any relevant specialty certifications or pre-approvals
GCs weight this section heavily for specialty trades where experience directly correlates with quality and safety outcomes.
Step-by-Step: How to Complete Your Prequalification Package
To prevent submission delays and avoid platform RAVS rejections, follow this sequential preparation workflow:
Gather Baseline Legal & Tax Documentation (Estimated Time: 1–2 Days) Pull your FEIN verification, active state contractor licenses, DUNS number, NAICS codes, and corporate governance papers. Verify all business names match your state registration exactly.
Request Insurance & Bonding Certificates (Estimated Time: 3–5 Days) Contact your insurance broker to issue an ACORD 25 COI. Ensure the certificate includes general liability, umbrella/excess coverage, automobile liability, workers’ compensation, and specific endorsements (Waiver of Subrogation and Additional Insured). Request a Surety Bonding Capacity letter from your broker.
Compile Safety Logs & Loss Runs (Estimated Time: 2–3 Days) Obtain signed OSHA 300 and 300A summary logs for the last 3 trailing years. Request an official EMR verification letter directly from NCCI or your state rating bureau, alongside 3–5 years of workers’ compensation loss runs.
Audit and Customize Written Safety Programs (Estimated Time: 1–2 Weeks) Cross-reference your company safety manual against your trade scope (e.g., Fall Protection, HazCom, LOTO). Ensure the manual cites company-specific procedures, responsible supervisor names, and correct federal/state OSHA codes.
Upload, Review, and Monitor Platform Accounts (Ongoing Maintenance) Submit all documents into ISNetworld, Avetta, or the GC’s portal. Track expiration dates annually for COIs, OSHA logs, and insurance letters to avoid sudden grade drops.
Common Prequalification Mistakes and How to Avoid Them
Research shows that up to 35% of project defaults are linked to risks that were flagged during prequalification but ultimately ignored. From the contractor side, these are the mistakes that most frequently cause rejections.
Incomplete Documentation
This is the most frequent and most avoidable mistake. An estimated 34% of prequalification rejections result from missing documents or blank fields. Rushing through the checklist, missing attachments, or submitting outdated versions makes your company look disorganized. Platform reviewers are not going to call you to ask for the missing page. They will reject the submission.
Generic Safety Manuals
Prequalification platforms evaluate your safety programs against specific structural criteria. A generic manual downloaded from a template site will not pass. Reviewers look for your company name throughout the document, references to the correct OSHA standards for your trades, specific training frequencies, documentation forms, and hazard controls that match your actual operations.
Assuming One Approval Covers All
Contractors sometimes assume that once their ISNetworld account is active, they are approved across the board. In reality, each hiring client may have its own requirements, its own thresholds, and its own required programs. Being “green” with one operator does not mean you are green with another. Check your status under each hiring client individually.
Treating Prequalification as a One-Time Event
For small to mid-size companies, ISNetworld compliance often falls on one person who is already wearing five other hats. After the initial push to get everything submitted, maintenance falls through the cracks. Insurance expires. New OSHA logs need to be uploaded. Training records for departed employees need to be removed and new ones added. The contractor prequalification checklist is a living document.
EMR or TRIR Above Threshold with No Explanation
If your safety metrics exceed the hiring client’s threshold, a flat number with no context is worse than a marginal number accompanied by a documented corrective action plan showing what went wrong and what you changed. GCs evaluate trajectory, not just snapshots.
Over-Relying on the Questionnaire Alone
From the GC’s perspective, prequalification questionnaires are a starting point, not an endpoint. PQQs are static and can be outdated the moment they are submitted. Without ongoing verification, organizations risk approving contractors who look compliant on paper but deviate in practice. GCs should pair prequalification with field audits, periodic document reviews, and active safety performance monitoring.

Frequently Asked Questions
What is a contractor prequalification checklist?
A contractor prequalification checklist is the complete list of documents, safety metrics, insurance certificates, written programs, financial records, and project references that a general contractor or hiring client requires before allowing a subcontractor to bid on or perform work. It functions as both a risk screening tool for the GC and a preparation guide for the contractor.
What safety metrics do GCs check during prequalification?
The primary metrics are EMR, TRIR, and DART rate. Most GCs require three to five years of history for each. Common thresholds are EMR below 1.0 to 1.2, TRIR below the industry average of 2.3 (and often below 2.0 for construction), and no fatalities or willful OSHA violations.
What happens if my EMR is above 1.0?
An EMR above 1.0 does not automatically disqualify you everywhere, but it closes doors. It disqualifies contractors from an estimated 58% of public bid opportunities. Your best approach is to document a corrective action plan, show a downward trend in your incident rates, and invest in the safety program improvements that will bring your EMR down over the next insurance cycle.
Do I need ISNetworld and Avetta, or just one?
It depends on your hiring clients. There is no reciprocity between platforms. If one client uses ISNetworld and another uses Avetta, you need accounts on both. Many contractors maintain profiles on two or three platforms simultaneously.
How long does prequalification take?
Initial setup on a platform like ISNetworld or Avetta typically takes two to six weeks if your documents are already prepared. The RAVS review process alone can take weeks, and rejections requiring revisions can extend the timeline further. Starting prequalification before a specific project is on the table is always the better approach.
What written safety programs are required?
The specific programs depend on your registered trades and your hiring client’s requirements. Common requirements include fall protection, lockout/tagout, confined space entry, hazard communication, respiratory protection, drug and alcohol, excavation, electrical safety, and emergency action plans. ISNetworld may require 8 to 40 programs depending on your scope of work. For help building or improving your written programs, see ESR’s OSHA written program requirements guide.
How often does prequalification need to be renewed?
Prequalification is ongoing. Insurance certificates expire annually. OSHA 300A summaries must be updated each year. EMR letters are issued annually. Training records change as your workforce turns over. Most platforms require periodic document updates, and failing to maintain your account can result in dropped grades and removal from approved vendor lists without warning.
Can a consultant help with contractor prequalification?
Yes. Many contractors, particularly small to mid-size companies, work with safety consultants who specialize in prequalification support. This includes writing or rewriting safety programs to meet platform review criteria, configuring platform accounts, preparing OSHA log documentation, and managing the ongoing maintenance that keeps your profile in good standing.
