Multi-Story Team Coordination Standard

Purpose

A single tech on a two-to-four-story job works alone all day and still misses the panes only reachable from a ladder nobody was free to foot. Put two or more techs on the same elevation without a coordination standard instead, and you get ladders repositioned into each other's fall zone, a water-fed-pole hose crossing a walkway a customer is using, and nobody who can say the site is clear before a ladder goes vertical. This standard is the crew choreography for a multi-technician team job: who clears the drop zone, how position changes get called, how equipment moves between people, and what stops the crew when the coordination itself breaks down.

Scope

Covers residential and light-commercial jobs up to roughly four stories worked by a team of two or more technicians using ladders, extension poles, and water-fed-pole systems from the ground or from accessible roof and balcony levels.

It does not cover suspended scaffold, boatswain's chair, or powered-platform work; that is high-rise territory the high-rise-versus-ground-level reference and the powered-platforms-for-building-maintenance reference own, and a job requiring rope descent or a permanent building anchor is out of scope for this SOP entirely. It does not cover individual ladder setup geometry, duty ratings, or the 4-to-1 setup rule, which the ladder-safety ANSI A14 reference owns; this SOP assumes each tech can set up a compliant ladder alone and adds what changes once a second person shares the elevation.

Roles and responsibilities

The procedure

1. Set the drop zone and assign a named foot before any ladder goes vertical. The team lead identifies the elevation's fall zone (roughly the ladder's working height plus a margin on each side), clears it of foot traffic and parked vehicles, and assigns one specific person to foot the ladder base, not "whoever's nearby." Acceptance: the drop zone is clear and one named person is standing at the base before the elevated tech's first foot leaves the ground. Wrong looks like a ladder going up while the crew is still unloading the truck and a delivery driver is walking through the zone. Stop rule: no named foot person means no ladder goes vertical, regardless of how far behind schedule the crew is running. Hazard: a foot person also watching a second task, a phone, unloading, is functionally unfooted; the only job during this window is the ladder.

2. Call every position change out loud before making it. The elevated tech announces before shifting the ladder ("moving right, three feet"), before climbing past the tie-off point, or before switching from ladder to pole reach on the same pane, and waits for the foot tech's acknowledgment before moving. Acceptance: every position change gets an announcement and an acknowledged "clear" before it happens. Wrong looks like a silent reposition because it's "just a few feet," made while the foot tech has stepped away to relay a bucket. Stop rule: any position change made without an acknowledged call-out stops that tech in place until contact is re-established; this is a same-day training correction, not a note for later. Hazard: an unacknowledged move is an unfooted move even if the same person is technically still standing there.

3. Sequence elevations so no tech works directly above another. The team lead assigns each tech to a separate elevation or a separate horizontal section of the same elevation, with enough separation that a dropped tool can't reach anyone below, and holds that assignment until the lead reassigns it. Acceptance: no two techs occupy vertically overlapping work zones at the same time. Wrong looks like a second tech starting a lower window directly under a first tech still working the floor above because that section "looked open." Stop rule: any tech who finds themselves working under another tech's active position stops, relocates, and reports it to the lead so the sequencing is corrected before it repeats on the next elevation. Hazard: a dropped squeegee or a bucket-lip failure from height is a real strike hazard even from two stories; a second tech on site is what creates this route, and it needs its own control here.

4. Relay equipment and chemistry through the ground tech, never by tossing or leaning-and-reaching. Buckets, poles, and refill water move via a hand-to-hand relay or a rope-and-bucket line the ground tech controls; an elevated tech does not overreach off a ladder to grab a handed-up item, and nothing gets thrown in either direction. Acceptance: every item transferred between levels passes through the ground tech's hands or a controlled line. Wrong looks like an elevated tech leaning off the side rail to grab a tossed rag because climbing down is slower. Stop rule: any overreach observed, belt buckle past the side rail or a reach beyond arm's length, stops that tech, who climbs down and repositions before continuing; this is the same overreach mechanism the ladder-safety reference names as the most common ladder-fall cause, and a second person on site is what makes it enforceable instead of self-reported. Hazard: a rope-and-bucket line gets its own load check before first use each day; a frayed or undersized line is a dropped-load hazard the same as a bad hand-off.

5. Hold a mid-job check-in at the halfway point of the elevation count. The team lead confirms fatigue, weather, and equipment condition haven't changed since the morning brief, and rechecks the drop zone against current foot traffic. This crew's ladder wind-limit policy, set at the morning brief, is a shop default of 20 mph sustained or gusting for extended-ladder or WFP work, tighter than the ladder's static rating because a hose or a tool bag catching wind fails before the ladder does. Acceptance: every tech gives a verbal status and the drop zone gets a fresh visual check. Wrong looks like skipping the check-in because the job is on schedule; wind and foot traffic both change over a multi-hour job in ways a morning brief can't predict. Stop rule: any tech reporting fatigue, or any wind reading at or above the crew's stated limit, pauses elevated work on that elevation until the lead names a specific resume condition, not "we'll see." Hazard: wind loading on an extended ladder or pole is a stability hazard distinct from footing; a foot tech cannot compensate for wind the way they compensate for a slipping base.

6. Close out the elevation and reconcile every person and every tool before moving the crew. The team lead confirms every tech is on the ground, every ladder is down or secured, and every tool and container is accounted for against the morning's load-out count before standing down the drop zone. Acceptance: a spoken headcount matches the crew roster and a tool count matches the load-out sheet. Wrong looks like trucks moving to the next elevation while one tech is still coiling a hose on a balcony out of sight; a headcount taken from memory instead of spoken aloud misses this every time. Stop rule: a headcount or tool count that doesn't reconcile holds the whole crew in place until it does; nobody drives to the next stop on an unreconciled count. Hazard: none new; this step exists specifically to catch what steps 1 through 5 leave open if nobody formally closes them.

The record this produces

The morning load-out count, the mid-job check-in status per tech including any wind hold, any position-change or overreach correction the lead logged, and the end-of-elevation headcount and tool reconciliation. The reconciliation is what confirms nothing, a line, a harness component, a pole section, got left on a roof or balcony, and the lead's log is what a shop reviews first after any near-miss.

Worked pass: a three-story medical office, a wind hold, and a line left behind

Crew of three, a three-story light-commercial building, front elevation and one side elevation. Morning load-out: two ladders, one WFP unit, four chemistry containers, one rope-and-bucket relay line.

Step 1: the lead sets the drop zone on the front elevation and names tech B as foot for tech A's ladder. Step 2: tech A calls "moving up two rungs" before repositioning; tech B acknowledges before it happens. Step 3: the lead assigns tech A to floors two and three on the front elevation and tech C to ground-floor WFP work on the side elevation, no vertical overlap between them. Step 4: the relay runs cleanly through tech B for two water refills.

Step 5 is where the pass takes its stop rule. At the halfway check-in, after the front elevation and before the side elevation, tech A reads a phone weather app showing 22 mph sustained, above the crew's stated 20 mph limit. That fails the step's acceptance condition. The stop rule fires: elevated work on the front elevation pauses, tech A comes down, and the crew shifts to ground-accessible tasks on the side elevation while the gust holds. The lead names the resume condition as a sustained reading back under 20 mph for ten minutes, not a guess.

Step 6, once wind clears and the front elevation resumes and finishes: the headcount reconciles at three, but the tool count comes up one short. The rope-and-bucket relay line used in step 4 is still coiled on a second-floor balcony ledge, left there when tech A climbed down for the wind hold. The stop rule holds the crew in place; tech B retrieves it once the wind is confirmed clear, the count reconciles at four containers and both ladders down, and the crew moves to the next building only after that.
