Also included in the removal was ancillary equipment such as a condensing unit, rotating and static exciter with cabinetry, condensate pumps, feed water pump, heat drain pumps, feed water heaters, moisture separators, hydrogen cooling systems, the lube oil system, the throttle and control valves at the head of the steam turbine, the unit’s controls, interlocks and a 100-ton overhead bridge crane.
Flooring
R. Baker & Son’s commitment to recycling and philosophy of being “green” was implemented throughout the demolition operations. Metals, concrete and brick were sent offsite for recycling. Wood timbers, consisting of yellow pine and Douglass fir, were salvaged and sent to a mill for reuse as architectural wooden beams and hardwood flooring.
Door Installation/Replacement
Drywalls
Framing
A curtain wall is characterized as the thin outer covering of a building; the exterior walls are non-structural, normally aluminum-framed, containing infills of glass, metal, or flat stone. The framing is connected to the building construction and does not bear the floor or roof loads of the building.

Demolition
R. Baker & Son All Industrial Services provides industrial and commercial demolition services throughout the State of New Jersey (NJ) as well as nationwide, Puerto Rico and Canada. We take great pride in our exceptional safety record, expert trained employees and our fleet of specialized demolition heavy equipment. We are also a Minority and Women-Owned Business Enterprise (M/WBE).
Prior to any work being performed several pre-demolition and abatement tasks needed to be completed. All utilities were disconnected from the buildings and temporary electric and water lines were installed to facilitate the work. An OSHA engineering survey was completed, notifications were submitted and all permits were obtained. Universal wastes (mercury switches, ballasts, fluorescent light tubes, etc.) were collected, characterized, containerized and the shipped offsite for proper recycling. Proper sidewalk bridges, barricades and fencing were installed to protect the surrounding public and structures. Scaffolding was also installed around the entire 5 story building, including the penthouse. The scaffolding consisted of double plank wood members with 2 ply debris netting.
Gate Replacement/Installation
Driveways
The controlled demolition of existing features were coordinated with construction of new sub-staion building and equiptment. During the work day the area was constantly cleared of all debris and potential hazards and at the end of each shift the demolition area was broom swept. All debris was live loaded on a daily basis including curb, concrete, asphalt and driveways which were all removed and recycled. Total building demolition included slabs and foundations and all voids were backfilled and leveled.
Excavation
The one UST and one AST were also demolished and removed from the site. The tanks were properly drained and cleaned prior to excavation or removal. The tanks were then cut up on site utilizing an excavator with shear attachment and then sent offsite for scrap metal recycling.
Though New York City strictly enforces disposition of construction and demolition debris, it encourages but does not require recycling of C&D waste. R. Baker & Son is wholly committed to reuse and recycling of demolition debris to ease environmental impact, conserve natural resources, and save energy. Demolition waste materials that are currently recycled include asphalt, brick, corrugated cardboard, carpet, concrete, drywall, film plastic, fluorescent lamps, glass, land clearing debris, metal, pallets, roofing, and wood. Renovation, demolition and dismantling projects may also yield salvageable materials that can be reused, such as appliances, architectural features, circuit breakers, office furniture, windows and doors, and wood timbers. Certain solid waste cannot be categorized as construction and demolition debris. This can include asbestos, fluorescent lights, carpeting, etc.
Residential Roof Repair
As the abatement was being performed, R. Baker had an alternate crew dismantling and scrapping a rooftop stack and associated intake duct and exhaust duct. Once the rooftop stack was removed, new roof framing, metal decking, EPDM roofing membrane on rigid insulation, and recovery board were installed to close the opening made by the stack removal.
Residential Roof Replacement/Installation
Before demolition activities could be conducted, the structures needed to be abated of asbestos containing materials (ACM). ACM consisted of roofing materials, piping insulation, boiler insulation and gaskets. The insulation and gasket materials were abated using standard asbestos removal procedures. Due to the structural instability of the roofs, a variance was obtained to abate the ACM roofs using mechanical means and wet methodology. An asbestos trained operator in a Case 9060B excavator with grapple carefully removed the roofs, while trained laborers performed dust suppression, and placed the ACM directly into lined rolloffs.
The phased approach to the work was closely coordinated and allowed abatement and demolition to be conducted simultaneously. Working down from the roof, the demolition crews removed all loose items from the floors including desks, cabinets, partitions, etc. Once a floor was completed, the abatement crew would then enter and perform abatement of all non friable asbestos containing materials (ACM). The demolition crew would then come back to remove all sheetrock and drop ceiling so that the abatement personnel could come back in to properly abate the friable asbestos materials (mostly pipe insulation). The wrecking personnel then came back to remove all remaining items and expose the building beams which had ACM waterproofing which then needed to be abated. Finally, once all ACM was properly abated, the demolition work crews went back to the top of the building to manually demolish each floor.
Masonry
The lot consisted of several buildings on a 225 ft x 200 ft parcel in a combination residential and commercial area near downtown Brooklyn, NY. The buildings were mostly constructed of masonry and brick walls with wooden floors and structural members. The lot was bounded on three sides by active sidewalks and a shared common wall with an occupied building on the East side. Several of the multi-story buildings had structural problems including unsafe roofs, cracked structural beams and walls that bowed outward. In addition, a hotel bounded the southeast portion of the lot which utilized the alleyway for guest parking.
