High-Rise & Multifamily

High-rise and multifamily scheduling

Floor cycles, dry-in, hoisting and the inspections that close in each floor drive these jobs. We build and review P6 schedules for GCs, subs and owners that show the real path to the CO.

What drives the schedule

What drives a high-rise or multifamily schedule

Repetitive floors look simple until one slips. The schedule has to show how each floor releases the next trade and the next floor.

01The structure cycle. Forms and pours floor by floor, with trades following a set number of floors behind.
02Dry-in. Envelope and roofing release interior work. A late dry-in can compress the trades that follow.
03Hoisting and vertical transportation. Hoist and elevator availability limit how fast materials and crews move up the building.
04Rough-in and inspections by floor. Above-ceiling and in-wall inspections gate close-in.
05Trade flow on repetitive floors. When floors fall behind, trades bunch up on the same floors and productivity drops.
06Life safety, TCO and CO. Fire alarm, sprinkler, elevator and life safety inspections at the end.
Where time gets lost

Where these jobs lose time

+Dry-in slips and interior trades get compressed
+Repetitive floors bunch up and crews stack on the same floors
+Subs absorb the GC's recovery schedule
+TCO and CO dates held while the work behind them slides

How we help

Scheduling and review built on the floor cycle

01

Baselines built on the floor cycle

P6 baselines with the structure cycle, dry-in, hoisting, rough-in, inspections and close-in by floor.

02

Monthly updates and narratives

Progress validated floor by floor, with resequencing and stacking documented as they happen.

03

Logic and float reviews for subs

We check the GC's schedule for compressed durations, flipped logic and total float taken from your scope.

04

Time impact and delay analysis

TIA per AACE RP 52R-06 on dry-in and predecessor delays measures the completion-date impact, with cost documented separately.

FAQ

Questions we get on high-rise and multifamily jobs

Can you build a floor-by-floor schedule?
Yes. Each floor gets its structure, dry-in, rough-in, inspection and finish activities with logic, so a slip on one floor shows what it does to the next floor and the finish.
Dry-in slipped and the GC wants us to make up the time. What now?
We check when dry-in actually released your work against the baseline and document the compression. A TIA measures the completion-date impact, with cost documented separately.
Do you work for owners and developers too?
Yes. Independent review of the contractor's baseline and updates, with a plain memo on what is driving the dates.
We are a sub on a multifamily job. Can you help?
Yes. Electrical, mechanical, plumbing, fire protection, framing, drywall and every other trade. We review the GC's schedule for your exposure and keep your record.
