This building was designed by a recently deceased icon in the architecture world, and until 2019 was the tallest building in its city.
Where am I?
Answer: Green Building (Building 54), Massachusetts Institute of Technology. The Green Building is a 21-story concrete-frame structure designed by I.M. Pei & Associates and completed in 1964. The cast-in-place concrete is expressed on the exterior facades, with pre-cast units used at the window sills.

Vertical Access is called upon to assist with all kinds of difficult to access civil structures, not just buildings. Parking garages are no exception, and are increasingly coming under scrutiny by building codes departments across the country.
Last summer, New York State amended Title 19 of the New York Code, Rules, and Regulations to require periodic inspection of parking garages. An initial condition assessment is required prior to an issuance of an updated certificate of occupancy or certificate of compliance being issued for a new structure.
Deadlines are fast approaching. Existing buildings must complete an initial condition assessment prior to:
- October 1, 2019 if originally constructed prior to January 1, 1984
- October 1, 2020 if originally constructed between January 1, 1984 and December 31, 2002
- October 1, 2021 if originally constructed between January 2003 and August 29, 2018 (the date of the release of this new rule).
Following the initial condition assessment of a parking garage, such parking garage shall undergo periodic condition assessments on an ongoing basis every three years.
According to a recent issue of NYC Building News, the New York City Department of Buildings is currently recommending similar requirements for periodic parking garage inspections for adoption in New York City as a local law through the Department’s Periodic Code Revision Process.
Contact Kelly Streeter, P.E., our resident Qualified Exterior Wall Inspector, to see how we can assist with your parking garage inspections.
Kristen Olson, Mike Russell, EIT, and Patrick Capruso completed Level I Thermography Certification Training through the Infrared Training Center in Nashua, NH. Bolstering our team’s already existing infrared thermography skills, the course will help Kristen, Mike, and Patrick better collect quality data about differences in emitted infrared energy and account for measurement effects such as distance and emissivity using infrared cameras. This technology helps with our investigation of moisture infiltration and evaluation of subsurface conditions. Infrared thermography measures emitted and reflective heat coming from an object. This closely corresponds with the temperature of that object; the hotter it is, the more heat it will emit to its surroundings.
It is useful in building inspections to be able to “visualize” differential levels of heat emanating from a building. Water, for example, will heat up and cool down at a slower rate than the rest of a building façade. This makes it possible to view where there may be water infiltration using a thermal imager because wet areas exhibit different heat signatures, whereas a visible light image will not show the temperature differences. Steel rebar and relieving angles in a facade will similarly change temperature at a different rate than the surrounding material and therefore be distinguishable in a thermal image.
The certification and training included:
- Comprehensive, hands-on introduction to thermal imaging and measurement systems for predictive maintenance applications.
- Hands-on instruction on how to interpret thermograms and make informed decisions using heat transfer concepts to analyze thermal images
- Learning about the latest in infrared inspection report generation and database software.
- Training to distinguish between hot spots and reflections, direct vs. indirect readings and qualitative vs. quantitative thermography.
Vertical Access spent the last two weeks at the Nebraska State Capitol assisting Dan Worth and Julie Cawby at BVH Architects and Stephen J. Kelley, Preservation Consultant, with investigations at the dome and other portions of the 400′ tower. We were retained to assist with a periodic inspection of the masonry following a multi-phased restoration project completed in 2011, and to help assess the condition of roof drains at the dome.
Week one was during a brutal heat wave, but our team kept their cool.
Our team was on site to help verify that those prior repairs were still intact and that no other conditions had developed that couldn’t be seen from the ground. In addition to a hands on inspection and documentation, VA performed water testing aided by infrared thermography to determine whether repairs were still holding and whether there were any leaks.

The History of the Capitol and Renovation
Nebraska State Capitol, the product of a nationwide design competition won by New York Architect Bertram Grosvenor Goodhue in 1920, is described as the nation’s first truly vernacular State Capitol. The present building, the third to be erected on this site, was the nation’s first statehouse design to radically depart from the prototypical form of the nation’s Capitol and to use an office tower. Constructed in four phases over ten years from 1922-1932, the building, with furnishings and landscaping, was completed at a cost just under the $10 million budget and was paid for when finished. To decorate the building, Bertram Goodhue selected Lee Lawrie, sculptor; Hildreth Meiere, tile and mosaic designer; and Hartley B. Alexander, thematic consultant for inscription and symbolism.
BVH and WJE completed an extensive multi-phase, multi-year restoration project of the entire exterior envelope of the Nebraska State Capitol. The $57.4M project was substantially completed in fall 2010 and included restoration of the masonry at the tower, base and courtyard, gold dome, the iconic bronze Sower atop the dome, bronze windows and copper roof.

Vertical Access often assists building owners, architects, engineers, with New York City’s Façade Inspection & Safety Program, or FISP, also known as Local Law 11. We would like to share some proposed changes that were recently brought to light by Brian Sullivan, a principal at Sullivan Engineering in a recent article in Habitat Magazine:
Brian sits on a DOB advisory committee that proposes changes to FISP regulations. The committee’s attention is now focused on Cycle 9, which begins in February 2020.
Here are some proposed changes:
- Probes to verify and document wall anchors in cavity wall facades might be required in the 9th cycle and every 10 years thereafter.
- The number of required close-up inspections might increase.
- Qualified Exterior Wall Inspectors (QEWI) might be required to have at least three years of relevant experience. (VA partner Kelly Streeter, P.E., is a certified QEWI).
- A time frame to resolve unsafe conditions might be required, with a maximum of five years.
- Monthly civil penalties for unsafe conditions might accrue and increase annually at a rate based on the length of sidewalk shed.
- The DOB might perform inspections before granting extension requests.
- Boards might be required to display a FISP condition certificate – either “safe,” “safe with repair,” or “unsafe” – in the lobby.

Recently I attended the Society of Professional Rope Access Technicians (SPRAT) Annual Conference in Cancun, Mexico, and brought home updates on some pretty important changes to SPRAT certification requirements that will be posted to www.SPRAT.org and go into effect April 1, 2019. A sampling of some of the changes are below. Even if industrial rope access is not part of your job, we think it is good for you to be aware of all the qualifications and skills Vertical Access rope access teams bring to your projects.
New SPRAT Certification Requirements Effective April 1st, 2019
Level I Certification requirements (changes)
- Horizontal Aid climbing (both fixed and movable) has been moved from a Level II skill to Level I
- The rescue scenario for Level I will now involve the casualty being in ascent, previously a Level II skill
- Level I testing will include proof of hands on skill with building various load sharing anchors in addition to inspecting ones built by Level II’s and III’s
- Additional skill assessments for rigging and operating a hauling and lowering system will include lowering and belaying with communication awareness of mechanical advantage (?)
Level II Certification requirements (changes)
- Vertical aid climbing will be required for a minimum of 10 feet
- Additional knots to know include friction hitch and load-releasable hitch
- Additional skills assessment of picking off a casualty through knots
- Additional skills assessment of rescue from aid traverse (using a rope-to-rope method)
- Rigging and operating a rope access system pre-rigged to lower
Level III Certification requirements (changes)
- Demonstrating an understanding of mechanical anchor systems (tripods and beam clamps) will be removed
- Rescues through knots will be moved to Level II
- Re-anchor or rope-to-rope rescues skills assessment will need to be performed mid-obstacle
- Hauling and lowering through knots (pitch head or platform) in both backup and main lines
- Additional job safety components added to the written test regarding the Job Hazard Analyis or Job Safety Analysis
More information about SPRAT can be found here.
At the conference, we also discussed the 2018 revision to ANSI 121 – Tool Tethers, that could have impacts across all facets of the construction industry.
ANSI 121 – Tool Tethers
ANSI 121 – Tool Tethers is currently rolling out the 2018 revision to incorporate new regulations in response to increase in incidents. This update will see impacts across all areas of the construction industry, not just industrial rope access.
At the SPRAT conference, we discussed some of the following from the new revision that will impact the way we approach our rope access work.
- Modification of tools will no longer be allowed for tethering (no drilling holes, etc)
- No duct or electrical tape will be allowed – a specialized tape is recommended that acts upon tightness of winding
- Every component that can easily come off needs a tether (for example, batteries on drills)
- Locking carabiners with captive eyes need to be used to tether tools and loose accessories that travel with the person
- Declarations of conformity should be issued by suppliers
- Label requirement guidelines are detailed in the revision
- There is now a defined standard on approved containers where tools can be stored without a tether

(Hint: It’s not all about rope access!)
In 2017 Vertical Access was retained by the City of Ithaca to perform a condition assessment of twelve hillside burial vaults located within the Ithaca City Cemetery in Ithaca, New York. Early this year the City of Ithaca voted to bond money toward the repair some of the hillside vaults.
The Ithaca City Cemetery comprises approximately 16 terraced acres on University Hill, between downtown Ithaca and Cornell University, with views over Cayuga Lake and downtown. Vehicle entrances are located at University Avenue, Stewart Avenue, and DeWitt Place. An additional pedestrian entrance is located at Cornell Avenue. Owned by the City of Ithaca and managed by the Parks and Forestry Division, the cemetery is actively used by pedestrians, cyclists, and dog walkers.
The City Cemetery is Ithaca’s oldest burial ground, dating from the city’s earliest settlement period in the 1790s. During the nineteenth century, it underwent multiple expansions, evolving into a park-like, formally-designed landscape following the “rural cemetery” movement.
Beginning in the 1860s, hillside burial vaults were constructed by prominent Ithaca families.
VA historian Kristen Olson conducted a hands-on inspection of the vault exteriors and video documentation of selected vault interiors with assistance from VA partner Evan Kopelson. Ithaca City Forester Jeanne Grace was on site to discuss findings.
The vaults range in overall condition from fair to poor. All exhibit signs of water infiltration and structural movement to some degree. Ten of the vaults are constructed with stone exhibiting widespread mortar failure and erosion. Delamination is widespread in units of locally quarried shale known as Llenroc.
Vertical Access documented existing conditions at all twelve burial vaults within the Ithaca City Cemetery. Notable and representative conditions were documented digitally using the Tablet PC Annotation System (TPAS®), with digital still images linked to condition annotations in an AutoCAD drawing. Additional investigation was conducted at three of the vaults using a GoPro camera mounted to a telescoping pole, inserted through a hole in the door or gap between the door and adjacent masonry, and illuminated with a flashlight.
A Borescope was used in an attempt to obtain imagery of the interior spaces of vaults with gaps that were too narrow to accommodate the GoPro, but the footage was not of use since the depth of the masonry at the door surrounds was generally greater than the length of the Borescope. A fiber optic “See Snake”, incorporating a camera with built-in illumination at the end of a flexible cable, was used to investigate the interior of one of the vaults which had an accessible rooftop vent.
Vertical Access prepared repair recommendations and cost estimates for each vault, with additional emergency stabilization recommendations and cost estimates for the three vaults found to have the most advanced deterioration.
While the current funding is inadequate to reconstruct all of the vaults, it will address the three vaults most in danger of collapse as identified in the Vertical Access study. The City’s continued investment is crucial to maintaining this valuable community historic site and greenspace.
Mike Russell, EIT, recently trained and was certified to the Society of Professional Rope Access Technicians (SPRAT) Level III Supervisor. According to SPRAT’s Safe Practices for Rope Access Work, all site work must be performed under the supervision of a Level III Supervisor.
Level III Supervisors are responsible for the overall rope access operations on site.
Mike joins Kelly Streeter, P.E. and Kevin Dalton as Level III Supervisors for Vertical Access.
As part of the training, Mike reviewed basic rope access techniques that we most often use in our site work as well as more advanced skills that are less often used, such as passing knots, rope-to-rope transfers, redirects, rebelays and horizontal aid traverse. The training also covered rope rescue techniques and mechanical advantage systems used for raising or lowering a casualty or other load.
SPRAT is a membership organization that promotes the development of safe practices and standards for rope access work in the United States, Canada, Mexico and beyond. Vertical Access is a member of SPRAT and active in its leadership committees.
