Davit Certification Requirements for Window Washing & Facade Access
engineering What a davit system actually is - and why it is certified separately
A davit is the crane-like arm that suspends a window-washing chair or a powered platform over the side of a building. On most South Florida high-rises it is a portable aluminum or galvanized-steel arm that drops into a fixed base - a socket, sleeve, or pedestal cast into or bolted onto the roof structure. The arm, the mast, the base socket, and the counterweight or through-bolt connection are all load-path components, and every one of them has to be certified, not just the anchor you can see.
This is why davits sit under ASME A120.1 (powered platforms and suspended access equipment) rather than being treated like a simple tie-back. A rope-descent tie-back anchor is proof-loaded as a single point; a davit is a lever that multiplies load into its base, so the arm and the socket are tested together under the moment they will actually see in service. If a building has both davits for the platform and separate tie-back anchors for the rope, those are two distinct certifications - see our rope-descent recertification guide for the anchor side.
science The load test: 2x working load, and the 1/16-inch fail line
Under ASME A120.1, davit posts and arms are proof-tested to twice the rated working load. The test load is applied at the position and angle the davit carries in service, held, and then released while a qualified person measures how the component recovers.
The pass/fail criterion is deformation, not just survival. If the arm, mast, or base shows permanent deflection greater than 1/16 inch after the load is removed, it has yielded - it failed the test and is tagged out of service until it is repaired or replaced. A davit that held the load but did not spring back is not a pass. The same discipline applies on the pure rope-descent side under ANSI/IWCA I-14.1, where tie-back anchors are proof-loaded to 2,500 lbs static, exactly 2x the 1,250-lb allowable service load. The theme across both standards is identical: prove double the working load, and reject anything that takes a permanent set.
event_repeat Inspection cadence and the paperwork owners must keep
Certification is not a one-time event. For any anchorage feeding a rope-descent system, OSHA 1910.27(b) requires the building owner to have the system inspected annually by a qualified person and certified at least every 10 years - and sooner whenever an inspection turns up a problem or after any event (a re-roof, a facade repair, a hurricane) that could have disturbed the base. Separately, OSHA 1910.140 requires a competent-person check of the fall-arrest anchor before each use, so the daily and the decade-long duties stack.
The owner's job is also a documentation job. OSHA makes the building owner keep the certification on file and hand it to the access contractor before work starts - test reports, load values, dates, the identity of the qualified person, and a drawing or schedule identifying every davit base by location. A binder with no test report, or a report older than the cycle, is functionally the same as having no certification at all. Keeping all of it on one recurring schedule is exactly what a compliance calendar is for.
water_drop Coastal davits fail in specific places - know where to look
In Deerfield Beach and along the rest of the South Florida coast, salt air attacks davit systems faster than the 10-year clock suggests, and the damage concentrates in a few predictable spots. The base socket or sleeve is the worst offender: water collects where the portable arm drops in, and galvanic corrosion sets in where an aluminum arm meets a steel base or where dissimilar metals meet the concrete embed. Through-bolts and embedded anchors rust from the inside of the slab where you cannot see them, so a base that looks clean on top can be losing the connection underneath.
Other coastal failure points: cracked or spalling concrete around the pedestal from rebar corrosion, seized or pitted pins and fasteners that no longer seat the arm correctly, worn base flanges that let the mast rock, and counterweight or track components on powered platforms that corrode out of tolerance. These are the findings that push a coastal davit into an early recert - and because La Gala self-performs corrective work, the same visit that flags a corroded base can specify and execute the repair.
gavel Why a window-washing contractor will not drop a rope without it
A reputable suspended-access crew is staking two lives on your rooftop hardware, and their own OSHA exposure rides on your paperwork. Under 1910.27(b) they are entitled to written assurance the anchorages are sound before they rig; without a current davit certification on file, a professional contractor simply will not tie off - which means your windows do not get cleaned and your facade work stalls. That is the everyday cost of a lapsed cert, before anyone gets hurt.
The regulatory cost is heavier. In 2026 a serious OSHA violation runs up to $16,550, and a willful or repeat violation up to $165,514 - per violation - and letting a crew suspend from an uncertified or overdue davit is precisely the kind of exposure inspectors treat as willful. The load testing and the sealed certification are performed by an independent licensed Florida PE; La Gala coordinates the engineering and self-performs any corrective or repair work, so the test and the fix live under one contract.
