Construction lien waivers explained: a state-by-state guide for subcontractors and GCs.

Construction lien waivers are simple in concept and complicated in practice. Every state has its own statutory landscape, several states mandate prescribed forms, notarization rules vary, and a waiver for the wrong amount or on the wrong form can void a sub's payment or expose a GC to lien liability. This is a working guide to the four types of lien waivers, the state-by-state form requirements every commercial sub and GC needs to know, the common mistakes that delay payment, and how AOS handles all 51 jurisdictions automatically.

Prevailing wage and certified payroll for mid-market commercial subs: a 2026 working guide.

Prevailing-wage compliance is one of the highest-stakes administrative obligations in commercial construction. Mis-classify a worker, under-pay a fringe rate, or file a non-conforming certified payroll and your firm can face debarment from public-works projects, penalty assessments, and back-wage liability that ripples across every project on the same contract. This is a 2026 working guide for mid-market commercial subs on Davis-Bacon and state little-DB statutes, WH-347 certified payroll mechanics, fringe-benefit accounting, and the compliance pitfalls that catch firms most often.

Construction COI compliance: how subs maintain coverage and how GCs actually verify it.

Certificate of Insurance compliance is one of the most labor-intensive recurring administrative tasks in commercial construction. Subs maintain four to six active policies, file COIs to every GC client on every active project, and chase renewals continuously. GCs verify dozens of COIs across hundreds of active sub-project relationships and have to track expirations against every project they're on. The cost of getting this wrong — whether you're the sub whose policy lapses mid-project or the GC who paid an uninsured sub — ranges from "annoying" to "company-ending." This is a working guide for both sides on how COI compliance actually works, the recurring mistakes, and how AOS handles the lifecycle.

Subcontractor prequalification for general contractors: a working framework.

Subcontractor prequalification is the GC's first line of defense against project risk — bonding capacity, insurance coverage, safety record, financial stability, references, and operational capacity all checked before the sub bids, not after they've been awarded. Done well, it filters out the firms most likely to default mid-project, deliver substandard work, or generate liability exposure. Done as a paperwork ritual, it produces a binder full of stale forms and zero actual screening.

Construction safety management and EMR: a working guide for mid-market commercial subs.

Safety management is the workflow that determines whether your firm can keep winning commercial work, what your workers' comp insurance costs, and (most fundamentally) whether the people on your jobsites go home in the same condition they arrived. EMR — the Experience Modification Rate — is the single number every GC will check during prequal, every insurance underwriter will base your rate on, and every owner will use to filter eligible bidders on certain projects. This is a working guide for mid-market commercial subs on how safety actually has to work.
