Ten years of NOAA station records replayed for any U.S. location, with last year’s weather, the NWS forecast, wetland and soil context, and a PDF you can hand to the team.

01 / Pick the site

Where is the work?

Search a town or address, or click anywhere on the map, then press Report this spot. Weather, flood, wetland and soil records are looked up from public sources on our server.

Tip: attach a project pair at the bottom of the page to add its project centers here.

02 / Plan the start date

Pick a start date. Get the weather report.

Pick a site first: search above, click the map, or choose a project.

03 / Why timing matters

How much longer does weather make this task?

Each start month is replayed against every year of recorded daily weather at the nearest NOAA station (the last 10 years). A day is lost when it crosses a stop rule below; the task finishes when it has banked its workable days. No forecast, no probability model: this is what actually would have happened.

Pick a point on the map. Weather history is available within 30 mi of an analyzed NOAA station with a complete 2016–2025 record.

04 / Site evidence

What does the ground and water look like?

Pick a site to see its flood zone, wetland, gauges, tides and soil.

05 / Task cost worksheet

What does a restricted work window cost?

work days × paid hours/day × (crew + equipment rate) × site multiplier + permit cost + closed days × standby cost

Crews are paid for the shift but only work while the window is open. A tighter tide, daylight or flood-stage window adds paid days. Every input starts blank; blank means unknown.

Hours of actual work, excluding waiting for the window.
Hours crew and equipment are billed on a day they mobilize.
Fully loaded crew rate from your estimate or quote.
Equipment billed for the shift, including idle time.
From 1.00. Enter your own factor for matting, access or wet-ground productivity. No default is applied.
Where the factor comes from: quote, estimator, past job. Required.
Fixed environmental compliance cost for this task. Enter 0 if none.
Cost of a mobilized day with no usable window. Enter 0 if demobilized.
Hours the site is workable each day after tide, daylight and flood-stage limits. 0 = closed day. Use the tide times above to estimate them.
Modeled task cost · USD · user scenarioNot calculated9 required inputs remaining.

Modeled cost, not a bid. Map screening (FEMA, NWI, SSURGO) is not a wetland delineation, permit determination or geotechnical finding. The multiplier and rates are yours.

06 / Shared access item

If both utilities use one access road, mat run or bridge

Split one shared item pro rata, for example by mat-days or crossings each utility uses. Optionally enter what each would pay to build alone to see the modeled difference.

3 required inputs remaining.

Possible shared activity, not savings. Each utility still files its own permits; a joint pre-application meeting is a question to raise, not an assumption.

07 / Project pair (optional)

Attach a project pair.

Adds both project centers as one-click sites on the map and keeps their filing evidence with the report.

Changing the pair opens a fresh worksheet. Up to 100 pairs from the active dataset are listed.

No pair attached. Use this worksheet for your own two-job scenario, or choose a pair to keep its source evidence alongside your assumptions.
