Netting Systems Design, Installation and Repair


Boston Hilton Downtown
Boston, MA

Shrink netting was installed both as a temporary stabilizer and as debris containment system. As protection against water infiltration a discrete colored sealant was applied at locations deemed permeable.


Helipad at University of Pennsylvania
Philadelphia, PA

Repaired and improved a selection of hardware supporting the perimeter fall protection net at the Helipad.



University of Buffalo, Center for the Arts
Buffalo, NY

A netting system was designed and installed over the Center for Arts skylight to contain any panels or laminations that may have become detached on the exterior side of the skylight.

Temporary Masonry Stabilization and Anchoring

 


Erie Community College Tower
Buffalo, NY

Installed a temporary stabilization system to mitigate the hazardous conditions at the exterior of the masonry on the tower. After installation of stabilization a full restoration of the tower was completed.


David N. Dinkins Municipal Building
New York NY

Using stainless steel straps ornamental masonry was temporarily stabilized. By using rope access techniques there was minimal disruption to building occupants and pedestrians while working above the courtyard.


General Theological Seminary Chapel Turrets and Tower
New York, NY

In order to contain areas of cracked, displaced and loose masonry temporary stabilization measures were designed and installed on four conical tower turrets and four octagonal Chapel turrets. Custom shrink netting was cut to the shape of the turret and held in place by a rope encirclement. Stainless steel strapping was installed around the freestanding drum portions of the tower turrets and the crown and brownstone units at the Chapel turrets. The challenge of accessing the turrets was solved by using industrial rope access techniques, rendering this difficulty a moot point.


St. Mary Assumption Church
Binghamton, NY

As part of the temporary stabilization work, fragments of stone and patching material was removed where the deterioration of these materials presented unsafe conditions. The loose material was removed with the assistance of hand tools. Netting was installed as a temporary mitigation measure at one stone belt course at the east transept wall and one belt course at the west transept wall. It is held in place with a continuous ½” diameter perimeter rope. The perimeter rope is woven through the netting, and the netting is further attached to the netting with crimped metal rings. All work was completed using industrial rope access.

Mitigation of Hazardous Conditions


Cathedral Church of St. John the Divine
New York, NY

In a time sensitive situation loose pieces of granite were removed from the south faces of the nave and clerestory and the east façade of the south tower to prevent dislodged stone from harming the public below. The work was completed using industrial rope access techniques over a span of 5 days, the time necessary for the assembly of scaffolding or swing stages. Follow up projects included mitigation work on the entire west facade, the north side of the nave and the north crossing.


Children’s Hospital Boston
Boston, MA

Removed potentially unsafe conditions at the exterior facades of five buildings of the Children’s Hospital Boston. The scope of the spall mitigation work at Enders, Fegan, Farley, Bader and Hunnewell Buildings was specified on elevation drawing prepared by the client. Industrial rope access was used to allow technicians hands-on access to perform the work.


Fifth Avenue Presbyterian Church
New York, NY

Loose and delaminating masonry was removed in difficult to reach locations as part of a temporary mitigation program.

Other Services


Upper Baker Dam*
Whatcom County, WA

Designed and installed a horizontal lifeline system on the outboard side of the dam’s spillway. The system enables safe access to a previously inaccessible area at the site.

 

Eucha Dam
Delaware County, OK


To aid the team in hands-on investigation of the five radial spillway gates at Eucha Dam we used power washing equipment to remove heavy soiling at select areas of radial gates to permit unobstructed investigation.

 


Fordham University
New York, NY

Removed, refurbished and reinstalled with new gearbox components the hour and minute hands on four tower clocks at Keating Hall. The clock hands on Martyrs Court were removed permanently. Each clock hand is approximately 6 feet long. Industrial rope access was used to allow a technician hands-on access to clock hands and gear boxes. This access approach allowed work to take place without disrupting student and staff access to campus buildings and without the construction of costly scaffolding.


Upstate Cancer Center
Syracuse, NY

Installed 1 meter tall letters spelling “Upstate Cancer Center” on the new hospital building using industrial rope access techniques.


Syracuse University
Syracuse, NY

Numerous spalls in pre-cast concrete panels at a Syracuse University dormitory were patched. Square profiles were cut around spall locations and each was filled with mortar. After 24 hours of drying, aggregate was applied to the mortar to match the surrounding facade. Rope access techniques were used to allow technicians access to spall locations.
