What is the best way to handle weather delays and rescheduling?

The best way to handle weather delays is to decide the rules before the weather arrives: what conditions stop each kind of work, who makes the call and by what time, what the crew does on a lost day, and how the customer is told. Then, when a day is lost, move every visit that depended on it, not only that day, and write down what happened.

Decide your stop rules in advance

A foreman standing in drizzle at 6:30 should not be making policy. Write the limits down by type of work. Typical triggers:

• Rain. A probability and an amount, for example 50 percent or more and a tenth of an inch. Exterior concrete, roofing, coatings and excavation each tolerate rain differently.
• Temperature. Concrete, mortar, adhesives, sealants and paint all have manufacturer limits, usually printed on the data sheet. Follow the product, not a habit.
• Wind. Lifts, cranes, roofing and sheet goods have limits set by the equipment maker and by safety rules.
• Heat. Heat affects both people and materials. Plan earlier starts, more breaks, or a stop.

Watch the forecast three to five days out

A lost day you saw coming on Monday costs far less than one discovered at the gate. Check the forecast for each job site, not for the office: jobs twenty miles apart get different weather. Mark the days at risk and decide early which jobs can swap.

Have rain-day work ready

Keep a short list at all times:

• Interior work on other jobs
• Punch lists and warranty calls
• Shop work, prefabrication, loading for the next job
• Equipment maintenance
• Training and safety meetings

A crew sent home is a cost. A crew moved to useful work is not.

Who decides, and when

Name one person, and set a time, for example 5:30 in the morning or 4:00 the afternoon before. Crews should know by when they will hear and how. If the call is always made the same way, nobody drives to a closed site.

Move the whole chain

One lost day rarely costs one day. The pour that slipped moves the saw cutting, the sealing after cure, and the next job that crew was due on. Move every visit that follows, then look at what the move collided with. Moving only the first day leaves you with a schedule that is quietly wrong for two weeks.

Protect the work in place

Before the weather arrives: cover fresh concrete and masonry, secure loose material, close up openings, pump excavations, tie down anything the wind can take. Damage to finished work costs more than the delay.

Tell the customer the same day

Send a short written note to the general contractor or the owner: the date, the condition, what work was stopped, and the new dates. Many subcontracts require written notice of a delay within a set number of days if you want a time extension. A note sent that day meets it. A conversation remembered three weeks later usually does not.

Keep the record

For each lost day, keep the weather for that location, a photo of the site, and the notice you sent. Weather is normally an excusable delay: you get time, not money. You get neither without a record.

Do not rush the return

The pressure after a delay is to make up time. Working on saturated ground, coating a damp surface or pouring ahead of a freeze produces rework that costs more days than the weather did.

Where ConstructStream fits

ConstructStream reads the forecast for each job's location and marks the visits where rain is likely, using the rain rule your company sets. A rain day moves the whole line of visits behind it, and the crews see the new dates on their phones. After the fact, each job keeps the weather for the days it was worked, so the record is there when a time extension is argued.
