Illinois Public-Works and Prevailing-Wage Acquisition Diligence

Identify the covered population

Start with every public body, project, contract and subcontract in the review period. Record project location, awarding authority, contract number, dates, prime/subcontractor role, labor classifications, bid assumptions, payroll periods, certified transcripts, change orders, retainage, claims and remaining work. Counsel should determine legal coverage; the diligence team should ensure the population is complete.

Rates are county, classification and time specific

The Illinois Department of Labor publishes current county rate schedules and archives prior rates. The current page states that schedules apply based on the effective date identified there and that public bodies must notify contractors and subcontractors of compliance obligations. Do not use today's rate to test an older payroll without checking the applicable archived schedule, classification and locality.

Reconstruct payroll at worker level

Subcontractors do not end the inquiry

Obtain the full subcontractor list, agreements, insurance, payroll/certification evidence, payment status and notices. Review how the prime monitored compliance and whether the purchase agreement allocates known and unknown claims. A low subcontract price may be a warning if it depends on noncompliant labor assumptions.

Re-underwrite public-work backlog

For each open job, update remaining labor hours by classification and applicable wage/fringe assumptions, then add material, equipment, supervision, bond, insurance, subcontractor, closeout and warranty costs. Include known rate changes and schedule delays. Compare revised gross profit with bid and latest WIP estimates. Review assignment, change-of-control, prequalification and bonding implications with the awarding authority and advisers.

Claims and records

Review agency correspondence, worker complaints, audits, debarment searches, wage notices, liquidated damages, certified-payroll corrections, union issues and counsel files. Retain payroll and project records according to applicable requirements and transaction covenants. Do not destroy source evidence after creating a summary schedule.

Purchase-agreement issues

• Definition and treatment of public-work receivables, retainage and claims.
• Responsibility for pre-close wage, fringe, payroll and certification matters.
• Accuracy and completeness of project and subcontractor schedules.
• Notification of audits, complaints, rate changes and authority decisions.
• Assignment, consent, bonding and prequalification conditions.
• Escrow, indemnity or price mechanisms selected by counsel for identified exposure.

Red flags

• One blended labor rate across counties or classifications.
• Certified payroll totals that do not tie to payroll registers or cash.
• Large fringe credits without plan and payment evidence.
• Public and private hours allocated manually at period end.
• Subcontractors excluded from the compliance review.
• Backlog margin based on bid-date rates despite later effective schedules.
• Retainage treated as current cash without closeout analysis.

Diligence deliverable

Produce a covered-project register, worker-level test, exception schedule, subcontractor review, current/open-project cost-to-complete analysis, audit/claim log and a transaction issues memo. State the period, rate schedules and sample or full-population method used. Legal conclusions belong to counsel.

Reconcile the project population

Start from revenue/customer reports, contract register, WIP, accounts receivable, cash receipts and public-body/vendor records. Compare the lists and investigate projects that appear in one system only. Search for subcontracted public work where the seller is not the prime. The risk population can be missed if diligence requests only projects management labels “government.”

Worker-level testing procedure

1. Select high-hour, low-rate, multiple-classification and overtime workers plus a random sample.
2. Obtain timecards/field records, payroll register, pay statement, certified transcript and proof of payment.
3. Match project, date, work performed, classification and applicable county schedule.
4. Recalculate base wage, fringe, overtime and deductions.
5. Aggregate exceptions by project/pay period and determine whether broader testing is required.

Fringe-benefit evidence

Document the plan or payment supporting each claimed fringe credit, eligibility, contribution timing, worker allocation and any cash-in-lieu treatment with qualified advisers. Reconcile employer records to plan/provider evidence. A spreadsheet allocation without underlying contribution support is not enough.

Accrue known exposure in job economics

For identified rate, classification, overtime, fringe or record exceptions, estimate wage difference, related taxes/contributions, adviser cost and schedule or contract consequences with counsel. Keep the accounting estimate, legal conclusion and negotiated transaction remedy separate. Update open-job cost to complete using compliant labor assumptions.

Bonding and prequalification continuity

Review bond program, indemnitors, aggregate/single limits, open bonds, claims, financial reporting and change-of-control requirements. Ask whether the buyer must qualify independently and whether existing bonds/contracts continue. Backlog that cannot be bonded, assigned or staffed under the buyer's structure should not be treated as ordinary transferable work.

Post-close control plan

Assign responsibility for rate updates, classification decisions, certified payroll, subcontractor monitoring, record retention and notices. Train payroll, project management and field supervisors. Test the first post-close payroll on every active public project and review the first new bid's labor assumptions before submission.

Subcontractor testing

Obtain every lower-tier subcontract, certified payroll submission, invoice, payment record, insurance certificate, bond where applicable and compliance communication. Match subcontractor workers and classifications to the project population. A prime contractor's file should not be treated as complete merely because the subcontract price was fixed or a certification was signed. Escalate missing or inconsistent records to counsel and expand testing when an exception suggests a systemic control failure.

Recalculate bids and remaining work

For active backlog, compare the wage schedule and classifications used in the bid with the schedule applicable to the project and remaining performance. Recalculate labor hours, overtime, fringes, payroll burden, supervision, escalation and subcontractor cost. Identify bids whose apparent margin depends on an unsupported classification, credit or productivity assumption.

Model the cash calendar as well as final margin. Certified payroll, retainage, bond costs, slow public payment and subcontractor timing can create a financing need even when a project is profitable. Reconcile the result to the acquisition's working-capital target and lender projections.

Transaction documentation

Maintain a schedule of covered projects, known exceptions, estimates, notices, audits, claims and post-close responsibilities. Counsel can determine representations, indemnities, escrows or other allocation. The diligence team should provide a traceable population and calculation rather than a general statement that payroll was "handled by the office."

Separate an arithmetic variance from a legal finding

In an illustrative payroll sample, twelve covered hours with a $4 hourly cash-wage difference and $2 hourly fringe difference produce a $72 arithmetic variance before any other amount or legal conclusion. The actual required rates, classifications, dates, credits and applicability must come from the correct authority and professional review. These example rates are not an Illinois schedule.

Retain the sampled worker/job/period links privately and reconcile the sample to the project population. A calculated difference can inform further diligence; it is not automatically the final liability or a price deduction. Connect supported remaining costs to the backlog review.
