Trinitas Medical Center Roof Rehabilitation/ Restoration Project, Elizabeth, NJ
The Medical Center project scope of work consisted of rehabilitating & restoring the roof system & the exterior of the elevator penthouse. The North Tower building is approximately 133,000 SF and 120+ feet tall. The Hospital Building sits in north side of the campus in Elizabeth New Jersey for almost 60 years. Now newly restored, being an icon for the city, located two blocks from the town business center & Union County Court House, 6 blocks from the train station approx. 1 mile west of the US RT. 1 & 9 & 3 miles from NJ Turnpike Exit 13 in Northern New Jersey.
The original building was constructed in the 1950s with a (BUR) Built-up roof system. The rehabilitation work was for the later installed roof system constructed with EPDM single-ply membrane adhered to 1 1/2” Polyicanurate insulation system adhered to concrete deck below. With past high wind conditions, the roof system had lifted & pulled away from the deck and failed due too improper adhesion of the Polyicanurate insulation to concrete deck below & improperly installed roof drains were the main factors causing the failure and leaks to the roof system.
The elevator penthouse brick masonry was cracked in several areas also, had many open mortar joints with missing mortar, peeling paint, cracked, delaminating, and spalled bricks.
The code requirements for a high rise building roof system must be fully adhered or mechanically attached to the roof deck.
Structural Rehabilitation of Ventilation System Project for the Holland Tunnel
The Holland Tunnel Architectural & Structural Rehabilitation of Ventilation Buildings Project. One is situated in the Hudson River and the other on land at Riverside South in Jersey City, NJ. The newly restored buildings are an icon for the city. Located in the business center of Jersey City. 6 blocks from the Holland Tunnel entrance. 1 mile east of the US RT. 1 & 9 and NJ Turnpike Exit 14C. 2 miles east of New York City in Northern New Jersey.
CAI Restoration undertook a complex custom rehabilitation operation for the building envelope restoration and interior concrete repair of the Holland Tunnel Architectural & Structural Rehabilitation project located in Jersey City, NJ. The work on the Holland Tunnel ventilation buildings had difficult challenges to overcome while meeting stringent requirements and unique situational challenges. Chief among the concerns of the rehabilitation project were the need to keep the ventilation system operational throughout the duration of the project since the tunnel and the ventilation system in the buildings can never stop. It must operate on a 24/7/365 schedule for the safety of the employees working in the tunnel and the occupants in the vehicles driving through the tunnel. As part of this, it was important to carry out selective demolition processes safely, precisely, and delicately with minimal dust entering the intake fans. In addition, due to the need for subsequent trades work that follow, keeping to a tight time schedule was very paramount.
Kingswood Station Condominiums Stabilization Project - East Brunswick, New Jersey
The Kingswood Underpinning & Stabilization Project is a large Residential Condominiums, Townhouse Community in East Brunswick, Middlesex County, New Jersey, located in the north central part of the state. It was originally a previously abandoned farm & vacant land project.
Building 208-211 and several other units were built on unsuitable soils & fill that have experienced similar settlement issues.
Shortly after completion these buildings were experiencing settlement, cracking of drywall & exterior stucco wall finishes, doors not shutting or jamming up when opening, windows not opening and or sticking and jamming on opening & closing. Then later the problem got worse. There were visible cracks in the concrete Cablevision Stabilization Projects, sinking sidewalk slabs and sinkholes in flowerbeds near Cablevision Stabilization Project walls.
The owner’s representative had local contractors make the repairs. However, the situation of the settling worsened. It eventually was slanting the floors. They were uneven and leaning furniture towards walls. Also, uneven floors at dissimilar floor finishes, in the kitchen and bathroom areas.
There were two unsuccessful attempts by an engineer and two contractors to shore up and stabilize the Town House Building. The owner’s representatives then called CAI Restoration Services in to survey and evaluate the problem at the Townhouse site.
Cablevision Stabilization Project - Paterson, New Jersey
The Cablevision Stabilization Project was a re-development project from a previously abandoned project that was purchased from the City of Paterson by Dornoch Holdings, LLC. The project is in the City of Paterson on 75-81 Ellison St. just down the block from Lou Costello Memorial Park (Renowned Comedian), located in Northern New Jersey.
When the project was being constructed it was discovered by the contractor while excavating of the elevator shaft pit they encountered demolition debris. After further excavating and probing it was determined the debris was probably from the prior structure on the site. It was a possibility that the rest of existing pier footings was also constructed over unsuitable soils IE: demolition debris, cobblestones, broken bricks, masonry debris, etc. The project architect was then advised of the problem. A soil engineer was called in to inspect and he did additional testing and verified the situation of the unsubtle soil conditions of the site. The soil would not support the design loads of the proposed new building.
At this point all work at the site was stopped and the owner had to get hard answers on how to correct the problem. He then needed to make some tough decisions on how to pay for this cost overrun to correct the unsubtle soil issues.
This delay was costing him dearly since the CM, GC and subcontractors were contracted and working on the project. The materials & equipment was ordered and the project was in full swing until it came to an abrupt stop. Nothing was moving forward and the costs continuing & mounting. The owner needed solutions with the least cost and fastest turnaround to get the project moving again.
