Here's the quiet trap in this holiday weekend: nothing on the board is due Monday, because agencies don't set Labor Day deadlines. But 22 bids close on Tuesday, September 8, and another 30 close Wednesday the 9th — 52 deadlines packed into the first 48 hours after the holiday.

The problem isn't the dates. It's that Monday, normally your last working day before a Tuesday close, doesn't exist this time. Agency contract desks are closed. Nobody answers the question you saved for the end. No addendum clarifying that spec detail is coming. If your bid bond, your acknowledgments, or your subs' final numbers aren't in hand by Sunday night, Tuesday morning becomes a scramble with no lifeline.

Tuesday's list runs from CUNY's vertical-transportation maintenance packages and a Brooklyn parks tree-planting contract to Brookhaven's asbestos-demolition job and a run of M/WBE and SDVOB sub-bid deadlines — the quotes primes are waiting on to finish their own numbers. Wednesday is heavier still, thirty closings deep, including the Peekskill parking-garage rehabilitation and Kiamesha Lake's wastewater plant rebid.

So the weekend to-do list writes itself. Pull up everything you're bidding this week on the board and check three things today, not Tuesday: the due date hasn't moved (check the listing, then the agency's own posting), every addendum issued so far is acknowledged in your bid package, and your subs know their numbers are due to you Sunday, not Tuesday at coffee.

The full list, sorted by what closes soonest, is on the board — every row links to its permanent record and the agency's own posting. Enjoy the barbecue; just do the paperwork first.
