Delay analysis methodsThe SCL and AACE taxonomies, why they do not map cleanly onto each other, and why your records decided the method months before the dispute.Construction / ClaimsAugust 7, 2026

Records and evidenceWhich records support which analysis method, and what tribunals actually punish.Construction / ClaimsAugust 7, 2026
Extension of time in the United StatesThere is no single US rule. Federal contracting, private AIA-form work and each state's no-damage-for-delay law answer the same facts differently.Construction / ClaimsUnited StatesSeptember 1, 2026
United States delay claim clocksThree layers, and a claim can die at any of them: AIA's 21-day Claim window, FAR's stacked notice and cost cut-offs, and the CDA's six-year bar.Construction / ClaimsUnited StatesSeptember 1, 2026
Notice and time bars in the United StatesThe claim-within-a-claim trap. Whether a bare time request is itself a Claim, and why a Contracting Officer's grant of time never proves excusable delay.Construction / ClaimsUnited StatesSeptember 1, 2026

Acceleration and constructive acceleration in the United StatesA claim parasitic on the extension-of-time claim. The Fraser five elements, where claims die under Amatea/Grimberg, and the rules on protest and cost.Construction / ClaimsUnited StatesSeptember 1, 2026
VariationsScope and price. The five elements a variation claim must establish, why agreeing a value may not pay for the time it cost, and where each element is taken further.Construction / ClaimsAugust 7, 2026
What counts as a variationThe scope question, and why the Privy Council held in 2026 that it turns on the contract terms rather than on how the parties behaved on site.Construction / ClaimsAugust 7, 2026
Written instruction and waiverYou did the work and there is no written instruction. Five regimes, five answers, and on US public work the rule is one estoppel cannot cure.Construction / ClaimsAugust 7, 2026
Constructive and deemed variationsThe claim for a variation nobody instructed, and why the doctrine does not exist outside the United States, only functional substitutes measured differently.Construction / ClaimsAugust 7, 2026

Change order releasesImpact claims die in signed change orders, not in tribunals. The reservation language that works, and two citations the commentary gets backwards.Construction / ClaimsAugust 7, 2026
