Your bonding agent told you at the last renewal that there was plenty of capacity in the market, and that was true. What changed in 2026 is who gets it. The surety market is not shrinking the amount of bonded work it will write — it is raising the bar on which contractors qualify for it. For a general contractor, that distinction lands in one document: your WIP schedule. The 2026 surety market expects it to hold up to a mid-year look as readily as a year-end one, and to stand on its own without a phone call to explain the messy parts.
This post is the 2026 lens on a story this blog has covered before. Your surety underwriter reads four questions off your WIP schedule, and that read hasn't changed. What changed is how often the underwriter wants to run it and how little tolerance there is for a schedule that needs caveats. We'll cover what "hardening on selectivity" actually means this year, what underwriters now want in a WIP, what a schedule full of one-time explanations costs you, what the September 2026 expiry of the federal infrastructure tailwind means for your bonding program, and what a clean WIP signals to a 2026 underwriter. The angle throughout is capacity, not compliance.
Is the surety market hardening in 2026?
Yes — but on selectivity, not capacity. There is ample bonding capacity and healthy carrier competition in the 2026 surety market; what has tightened is the underwriting bar. Turner Surety & Insurance Brokerage (TSIB), in its 2026 Surety & Construction Forecast, frames the shift plainly: "Capacity isn't changing — it's selectivity" (TSIB, 2026 Surety & Construction Forecast, Jan 30, 2026). The capacity is there. The question is whether your file earns it.
That resolves an apparent contradiction. You'll hear the same market described as "soft" with "ample capacity" and as "hardening" in the same breath. Both are true once you separate the two ideas: capacity is the amount of bonded work the market will write, and it is plentiful; selectivity is the standard a contractor has to meet to be handed it, and it has gone up. The money is available, but the diligence is stricter.
The numbers behind the soft spell are real, and they are why it is reversing. The surety industry's direct incurred loss ratio fell to 20.5% through the third quarter of 2025, down from 24.9% in 2024 — a stretch near a 10-year best, fueled in large part by federally funded infrastructure work (AM Best, via Construction Equipment Guide, "Surety Market Enjoying the Sunshine"). Loss ratios that low mean carriers have been writing profitable business and competing hard for it. But a near-decade-low loss ratio is a peak, not a baseline, and underwriters are already raising the bar in anticipation of the cycle turning — which is the timing piece we come back to below.
What do surety underwriters want in a WIP now?
A surety underwriter in 2026 wants interim, job-level reporting: your numbers more than once a year, broken out project by project. TSIB's forecast names it directly: underwriters are placing "more focus on interim reporting and job-level transparency (not just year-end and interim financials)" (TSIB, 2026 forecast). Translated for a Controller: the underwriter wants a current WIP, attributed project by project, that explains itself — and they want it more than once a year.
"Job-level transparency" has a concrete meaning. It means every active project on the schedule is accounted for, with its margin, its billing position, and its remaining backlog visible on the row — and the over/under-billing position explained on the schedule itself, not in a follow-up phone call. A clean job-level WIP lets the underwriter answer the four questions they read off the schedule — are your jobs profitable, are you billing accurately, are you overextended, are your estimates reliable — without picking up the phone. In a selectivity-up market, the file that answers those questions on its own is the file that qualifies.
The interim ask is the newer pressure. A year-end-only WIP gives the surety a single data point to underwrite twelve months of decisions on. When a renewal comes in July, the most recent schedule on file is six months old — a 2026 capacity decision made off a December picture. Concretely, that means getting a WIP in front of the surety quarterly at a minimum, monthly ideally, rather than once at fiscal close. A current WIP that ties to your financials closes that gap — and the frequency itself is a capacity lever, because a clean, current schedule raises the underwriter's confidence rather than asking them to price in the uncertainty of a stale one (Grit Insurance).
What happens when your WIP keeps needing one-time explanations?
In a market with less patience for caveats, a WIP that needs explaining costs you capacity. TSIB flags exactly this as a marker of the 2026 shift: "less patience for repeated 'one-time' explanations in WIP schedules" (TSIB, 2026 forecast). A schedule where every other anomaly comes with a verbal "that's a one-time thing" does not stand on its own — and underwriters have stopped giving those caveats the benefit of the doubt.
Make the consequence concrete. A WIP that needs a phone call to explain the growing underbilling on Job 7, or to walk through why the margin on the parking structure slipped again, is a WIP the underwriter has to take on faith. Once is fine. A pattern of one-time explanations reads as a contractor who cannot produce a schedule that speaks for itself. In 2026, that reads as risk. The fix is not better explanations. It is a schedule that does not require them.
TSIB is specific about where the scrutiny lands. The 2026 forecast points to closer attention to "cash flow, underbilling trends, and reliance on key employees" in the WIP (TSIB, 2026 forecast). The underbilling-trend signal is the cleanest mechanical link between WIP quality and capacity: underbillings sit in current assets and inflate the working capital your surety credits you for, and an underbilling that keeps growing on a slow or losing job is the kind a surety discounts. That is why working capital is the number the surety weights most — and why a WIP that surfaces the underbilling trend before the underwriter finds it is worth more than one that buries it.
What does IIJA expiring in September 2026 mean for your bonding program?
The federal infrastructure tailwind that kept loss ratios near a decade low ramps down after September 2026 — and contractors who built their bonding programs on 2024–2025 conditions should expect a tighter underwriting environment heading into 2027. The Infrastructure Investment and Jobs Act (IIJA) drove much of the construction demand behind the 20.5% loss ratio through Q3 2025 (AM Best, via Construction Equipment Guide). As those appropriations wind down, the demand that made the soft spell soft softens with them. That is the macro answer to "why does my WIP have to be cleaner now?": the cushion is thinning, and underwriters are watching for the turn.
The takeaway is timing, not panic. Capacity is still ample today. The contractors who use the back half of 2026 to get their WIP into interim-ready shape are the ones who walk into a 2027 renewal with a current, reconciled, self-explanatory schedule — instead of scrambling against a stricter bar. The window to make WIP a routine, not a year-end fire drill, is open now precisely because the market is still soft on capacity.
One more piece of the 2026 underwriting desk is worth naming: the underwriter reading your WIP may not be only human. Per a December 2025 IA Magazine piece, "54% of underwriters now use AI-driven models to evaluate applicant risks" (IA Magazine, Dec 2025). A structured, human-attributed, machine-readable WIP — every figure traceable to a source and every estimate carrying a name — is the right response to both the human and the automated desk: the model reads structure, the human reads judgment, and a clean WIP holds up to both.
What does a clean WIP signal to a 2026 surety underwriter?
A clean WIP signals four things to a 2026 underwriter: it is accurate, current, reconciled, and attributed — a schedule where every figure is traceable and the over/under-billing position is self-explanatory on the row. That is the profile a selectivity-up market rewards. It is not a fancier schedule; it is one that answers the underwriter's questions before they are asked and survives the move from a year-end review to interim scrutiny.
Take Meridian Construction Group, the fictional GC whose numbers run through this series. Meridian carries $35.9 million of active backlog against a $75 million aggregate limit — 47.9% utilized, with $39.1 million of room left (how to track and grow that bonding limit covers the calculation in full). At a December 31 snapshot, that looks comfortable: nearly half the limit available. But backlog moves across the year. Win two new jobs in the spring and the room narrows; the year-end picture the surety underwrites off in July is no longer the real one. A current WIP shows the underwriter the room as it is, not as it was at fiscal close. In a selectivity-up market, that current read is the difference between capacity extended and declined.
The underlying logic hasn't changed from a soft market to a hard one. Available bonding capacity is still read straight off the WIP, on a cost-to-complete basis — aggregate limit minus active bonded backlog. What 2026 changed is the frequency and the standard: the underwriter wants that read more often, wants it to tie to your WIP schedule and your financials, and wants it to need no narration. A current WIP that reconciles to the general ledger removes the one-time explanations before they happen — when the schedule ties out, there is nothing to caveat. That is how you keep your construction bonding capacity reflecting your real position instead of a stale one.
A Procore-native WIP that runs every cycle — costs and contract values pulled from the job-cost ledger, a structured and attributed cost-to-complete collected from each PM, the schedule reconciled and ready to share with your surety at any point in the year — is the operational answer to a market that now wants exactly that. WIP Ready closes the WIP in about 45 minutes instead of 2–3 days, which is what turns interim, proactive submission from a heroic effort into a routine one. It reads from Procore and never writes back, and it never invents the cost-to-complete — the PM who knows the job owns that number, which is exactly why the resulting schedule holds up with a selective underwriter. The frame is capacity, not compliance: a clean, current WIP is how you keep the room a soft market is still offering. See the workflow at wipready.com.
Frequently asked questions
Is the surety market hardening in 2026? Yes — on selectivity, not capacity. The surety market has ample capacity and healthy carrier competition in 2026, but underwriters have become markedly more selective about which contractors they extend it to (TSIB, 2026 Surety & Construction Forecast). Capacity is not rationed; qualification standards are higher.
What do surety underwriters want in a WIP schedule in 2026? Interim, job-level reporting. Per TSIB's 2026 forecast, underwriters are placing more focus on interim reporting and job-level transparency — meaning your WIP should be current, attributed by project, and self-explanatory at any point in the year, not only at renewal (TSIB).
What does hardening on selectivity mean for a general contractor? Your WIP schedule needs to stand on its own without repeated verbal explanations. TSIB flags less patience for repeated one-time explanations in WIP schedules as a marker of the 2026 shift. A WIP that needs a phone call to explain a growing underbilling is a WIP that costs you capacity with the underwriter (TSIB).
What happens to surety bonding when IIJA funding expires? The federal infrastructure tailwind that drove a near-decade-low loss ratio — a 20.5% direct incurred loss ratio through Q3 2025, versus 24.9% in 2024 (AM Best, via Construction Equipment Guide) — ramps down after September 2026. Underwriting standards are expected to tighten as that demand softens, making a clean, current WIP more important heading into 2027 renewals.
How often should you send your surety a WIP schedule? More often than annually. Under the 2026 selectivity shift, a year-end-only WIP means the underwriter decides for twelve months off one snapshot. Quarterly at minimum, monthly ideally — and proactively, so the surety's picture of your business is never six months stale (Grit Insurance; Projul).
How WIP Ready helps
A hardening surety market does not ask for a different WIP — it asks for the same WIP, more often, and clean enough to need no narration. That is harder than it sounds when the schedule takes 2–3 days to rebuild by hand, because interim submission stops being realistic and you default to year-end. WIP Ready produces the bonding-ready ASC 606 schedule inside Procore: it reads your Procore project financials, collects a structured, timestamped cost-to-complete from each PM on their phone, reconciles the schedule, and outputs it in your surety's template — every figure tracing to a Procore field or an attributed PM submission. It does not set your bonding limit and it does not invent the cost-to-complete; it keeps the schedule current, attributed, and reconciled so the WIP your surety reads is one that stands on its own.
