Pull Tests NYC — Anchor Pull Testing & Proof Load Testing
DOB-required anchor pull testing by a Licensed Professional Engineer. We perform tension testing for post-installed anchors, scaffold ties, facade anchors, parapet tie-backs, and structural connections throughout all five NYC boroughs. Same-day and next-day scheduling available.
What Are Anchor Pull Tests in NYC?
Anchor pull tests — also known as proof load tests, tension tests, or tie-back tests — are field verification procedures that confirm post-installed anchors can safely support their required design loads. NYC Building Code BC 1704.32 mandates pull testing for mechanical and adhesive anchor installations in concrete and masonry.
Post-installed anchors differ fundamentally from cast-in-place anchors because their performance depends on field installation quality, substrate condition, and precise adherence to manufacturer specifications. Pull testing provides independent, third-party verification that each anchor meets its structural design requirement.
Our Licensed PE performs calibrated tension loading using certified hydraulic equipment, monitors each anchor for load-holding capacity and displacement, and issues a PE-stamped certification report accepted by NYC DOB, site safety managers, MEP engineers, and design teams.
We perform anchor pull testing throughout Manhattan, Brooklyn, Queens, Bronx, Staten Island, Westchester, and Long Island with fast scheduling to minimize construction delays.

Types of Anchor Pull Tests We Perform in NYC
From scaffold ties to structural facade anchors, we test all anchor types in concrete and masonry across every NYC borough.
Scaffold & Sidewalk Bridge Anchors
Every NYC construction site requires proof-tested scaffold tie anchors. We provide full anchor pull testing programs with certified PE reports accepted by NYC DOB and site safety managers.
Facade & Curtain Wall Anchors
Post-installed anchors securing facade cladding, EIFS, stone panels, and curtain walls must be tension-tested to verify wind load and dead load capacity. We test and certify all facade anchor systems.
Parapet Tie-Back Anchors
Parapet walls require properly anchored tie-backs to the building structure. We perform anchor pull tests for all parapet reinforcement installations, providing DOB-accepted certification reports.
Mechanical Equipment Anchors
HVAC units, generators, cooling towers, and rooftop equipment require properly installed and tested anchors per seismic and wind provisions. We test mechanical equipment anchorage throughout NYC.
Structural Post-Installed Anchors
Structural connections using post-installed anchors in concrete or masonry require special inspection and pull testing per BC 1704.32. We verify mechanical anchors, adhesive anchors, and undercutting systems.
Guardrail & Railing Anchors
Life-safety guardrails and handrails must be anchored to resist required lateral loads. We test railing post anchors and certify compliance for permit signoff and CO.
FAQs: Pull Tests & Anchor Testing in NYC
What is an anchor pull test in NYC?
An anchor pull test confirms that post-installed anchors in concrete or masonry can safely support their required design loads. Required by NYC BC 1704.32, the test applies controlled tension loading and is certified by a Licensed PE. Also called proof load testing, tension testing, or tie-back testing.
When are pull tests required in NYC?
Pull tests are required whenever post-installed anchors are used for structural or life-safety applications: scaffold ties, facade anchors, parapet tie-backs, structural connections, and mechanical equipment anchorage. NYC DOB may also require them as a condition of permit approval.
How many anchors need to be pull tested?
Testing quantity depends on specifications and applicable standards. Common rates are 10% of installed anchors, 5 per 100 installed, or 100% for critical life-safety applications. The Licensed PE determines the appropriate quantity based on anchor type and application.
What happens if an anchor fails a pull test?
Failed anchors are documented with the failure mode. Corrective action — re-drilling at a new location, deeper embedment, or a larger anchor — must be approved by the engineer of record. Failed anchors are replaced and re-tested before the installation is accepted.
Do you provide pull testing throughout NYC?
Yes. We perform anchor pull testing throughout Manhattan, Brooklyn, Queens, Bronx, Staten Island, Westchester, Nassau County, and Suffolk County. We offer same-day and next-day scheduling to keep your project on track.
