The Problem

Other apps give you data.

Not decisions.

A generic forecast tells you it'll rain at 60%. It tells you nothing about whether your crane crew should go up, whether your concrete pour should proceed, or whether today qualifies as an "adverse weather day" under your contract.

And when the delay happens, proving it — in a format your contracts team can actually use — requires piecing together weather records, industry standards, and contract clauses from separate tools.

Construction-Weather closes that gap. From daily operations to formal claims, from one location search.

Five Tools. One Platform.

Everything.

From Tender to Claim.

Everything a construction professional needs to manage weather risk — from pricing a bid to issuing a formal notice, reviewing delays, and building a contract claim.

Trade Advisory Intelligence

Built for the work

you're actually doing.

Wind speed is information. "Ground the crane" is a decision.

Construction-Weather tells you whether your crane, pour, or welding crew are a go — and names the standard behind every call. The ones your contracts team already knows.

Every threshold is sourced from published industry standards. Documented. Defensible.

Early Warning Notice

Formal Notice.

In Two Minutes.

When unsuitable days appear in your 14-day forecast, your contract likely requires you to notify the Employer at the earliest practicable opportunity. Menlo Construction Weather generates a fully drafted, contractually framed Early Warning Notice in Word format — from the same screen where you identified the risk.
01
Unsuitable Days Identified in Forecast
The 14-day lookahead flags days where forecast conditions breach trade-specific thresholds. A notification prompt appears automatically when unsuitable days are identified.
02
Enter Your Project Profile
Project name, contract reference, contractor, employer, engineer and site address. Entered once and saved — so repeat notices on the same project take seconds.
03
AI Drafts the Notice
The tool generates formal contractual prose for each affected day — specific forecast values, trade advisory constraints, anticipated impact on works, proposed mitigation measures, and a request for the Employer's response and direction.
04
Review, Edit & Issue
Download the Word document, review and edit as required, and issue to the Employer. Your early warning obligation is met. Your rights are reserved.

See What Others Are Saying
This is a game-changer. Integrating real-time weather alerts directly with specific site activities brings a much-needed consistency to onsite planning.

Not only does it streamline daily assessments, but it provides the clear, data-driven support needed for accurate Extension of Time (EoT) evaluations. Brilliant to see tech being used this effectively! Can’t wait to use it.
