Keeping Your Projects on Track
Advanced Architectural Grilleworks was chosen to assist with the MTA’s #7 line extension, bringing subway service to the far west side of Manhattan. This historical project was the first addition to the NYC subway system in 26 years. It required a massive engineering effort and 8 years of construction. The entire project featured high-end stainless steel hardware, wall panels, architectural grilles and architectural features.
Our linear bar grilles are an integral part of the ventilation system which delivers air to the commuter platforms. These custom, 304 stainless steel grilles had to enhance the aesthetic character of the station while providing exceptional corrosion resistance, sufficient directional air flow and a lighter weight. The existing field conditions necessitated linear bar grilles that are durable structurally reinforced to withstand the rigors of a subway environment including seismic changes and moisture.
The grilles chosen were based on the AAG400, deflected bar design with custom bar spacing and height. The frames were designed to mate end to end. As an added safety feature, we provided stainless steel tethers on each grille to ensure a seismic event could be withstood.
Lobby Face Lift
A midtown Manhattan lobby upgrade lost traction due to a vendor failure. Advanced Architectural Grilleworks was called in to rescue the project. Our team visited the site, examined the field conditions and created custom radiator enclosure covers exceeding all expectations –within a tight budget and delivery schedule.
The existing enclosures were in total disrepair. These 57 year old convectors were covered with dented, scratched and sagging perforated metal grilles. Adding to the challenge were the old, damaged aluminum extrusions surrounding the units. The replacements had to be aesthetically pleasing sturdy and quickly removable for access. The new design would also provide improved air flow through an interior baffle we created.
Our team designed a U shaped enclosure cover with reinforced channels to support any potential live load. These channels were welded and positioned between the pattern openings and wrapped with high temperature, black, aluminum tape ensuring no visibility from above.
The units were also designed with the field team in mind by providing custom mounting brackets for attachment to the existing window wall and the lobby side extruded frame. The outside wall mount design enables the building management team to quickly lift and remove the units for access to HVAC controls and for cleaning.
Since electrical access is required throughout the lobby area, our laser cutting capabilities provided precision openings into which pop-up electrical receptacles were installed.
Additional engineering features included concealed, oval openings to allow convection air flow through the unit. This was accomplished with a drop front panel creating a fresh, new look.
All of the units were finished to a #4 satin and then clear anodized.
Historical Renovations Our Specialty
The LeVeque Tower, A 47-story Art Deco-style building located in Columbus, Ohio was undergoing a major renovation providing our team the opportunity to be part of another classic historical restoration project. From 1927 until 1974, LeVeque was the tallest building in Columbus and even rivaled the Washington Monument; being taller by 3/8″. The tower, designed by C. Howard Crane, established the Columbus skyline for many years.
Advanced Architectural Grilleworks’ craftsmen were called upon to provide custom, oversized, laser cut, stainless steel panels which were installed throughout the lobby area. Since all the decorative metal grilles were unique, our engineering and design team custom scaled the AAG719 pattern in 14 gauge stainless steel. Varying borders and dimensions were created to achieve exactly the look the client was seeking. Using in-house, cutting edge technology what was once old was made new again.
