Far Rockaway Power Plant

The National Grid Far Rockaway Power Plant is a 100 megawatt, natural gas fired steam electric generating station. The station was originally commissioned in 1954 as a coal fired station and was converted to coal/fuel oil in 1966. Since 1994 the Far Rockaway station has utilized natural gas exclusively. The station was taken out of service in June of 2012 and in the late fall of 2012 North American dismantling was contracted to provide for the complete abatement and demolition of the power station.

Major Structures that were abated and dismantled include:

  • Unit #4 including the boiler house and turbine hall.
  • House boiler building.
  • Service building.
  • Circulating Water Intake Screen House.
  • Chlorinator House.
  • Fuel oil storage tanks including the 2,000,000 gallon Main Oil Tank and the 100,000 gallon Day oil tank, as well as, all ancillary underground and above ground piping and appurtenances.
  • Fuel Oil Transfer House.
  • Storage Building
  • Water Tank and Pump House
  • Fire Protection Building
  • Ash Silo Building
  • Continuous Emissions Monitoring Building
  • Coal Handling Structures
  • Transformers and Associated Overhead Transmission Lines
  • Circulating Water Intake and Discharge Tunnels
  • Barge Unloading Station
  • Groundwater Monitoring Wells
  • Permitted Production Water Wells.

Upon contract award NADC initiated preliminary project mobilization activities including permit acquisition. Detailed work plans and applications were filed with The City of New York Department of Buildings, Fire Department New York (FDNY), The City of New York Department of Environmental Control and The State of New York Department of Environmental Quality.

East Kentucky Power Plant Demolition

Spurlock Unit No. 1 Backend Equipment

Work Performed: demolition, environmental decommissioning, asbestos abatement, equipment recycling, asset recovery

Project Description

This project consisted of the demolition of the structure known as Unit No. 1 Boiler Outlet of the East Kentucky Power Cooperative H.L. Spurlock Power Station located at 1301 West 2nd Street in Maysville, Kentucky. The structure was multi leveled to a height of 150’-0” above grade, totaling 180,000 sq. ft. and was constructed of structural steel framing, supporting various pieces of equipment.

Project Details

East Kentucky Power Cooperative contracted North American Dismantling Corp. (NADC) to complete the removal of the structure down to the existing slab including environmental decommissioning and asbestos abatement. The demolition included the removal and/or recycling as scrap; the steel framing, all equipment and machinery contained within and all mechanical, electrical and ancillary equipment including ductwork, fans, piping, conduit, steel guard posts and railings. Major equipment included but was not limited to:

  • Electrostatic Precipitator (1) including transformer/rectifiers and controls. (The control enclosure located in the plant is not included);
  • Induced Draft Fans (2) including the fan, 2-speed motor, oil filled speed changer, and lube oil units (4000 volt, 3500/200 Hp, 888/710 RPM);
  • Forced Draft Fans (2) including the fan, 2-speed motor, oil filled speed changer, and lube oil units (400 volt, 1500/100 Hp, 710/590 RPM);
  • Rothemule Regenerative Air Heaters (2);
  • Babcock & Wilcox Tubular Air Heater (1);
  • Sets of Steam Air Heating Coils (Secondary air) (2);
  • Miscellaneous duct sections stored in the lay down area.

This equipment had been in use for approximately 26 years on the flue gas outlet of a coal fire utility boiler firing eastern bituminous coal.

In addition to removing all equipment mentioned above, NADC removed a No. 2 oil fired Combustion Engineering package boiler rated at 110,000 Lb/Hr at 25 PSIG and 455 Deg. F steam outlet temperature, including all auxiliaries such as misc. pumps, fan, and condensate DA/storage tank are to be removed as well.
An ash piping bridge on the west side of the precipitator was required to remain. It was supported by a cantilever off the precipitator support steel. NADC had to modify a portion of the steel in order to adequately support the piping bridge prior to its demolition activities.

Also included as a part of its scope of work, NADC was required to salvage and save the following:

  • Primary Air Fans (2) including the fan, motor, and the lube oil unit;
  • Set of Primary Air Steam Coils (1);
  • Two (2) Bridge cranes located in the precipitator pent houses.

All environmental issues were addressed and abated by EKP prior to the start of NADC’s work. The ducts were vacuum cleaned and the regenerative air heaters were water washed to remove bulk ash by the owner prior to NADC’s work. Storm sewers and catch basins located in the vicinity of the work area were covered with visqueen or filter fabric to prevent any accidental discharge into the storm system.

Because of the potential dust, NADC maintained a misting of water on the areas of the structure being demolished. Wetting the building not only eliminates dust, it also kept the chance of any fire to an absolute minimum.

Major Pharmaceutical Facility

Design/Build, Demolition
& Asbestos Abatement

Work Performed: design/build, demolition, asbestos abatement, new construction

Project Description

This project was a design/build project located in Southwest, Michigan. The original contract was for $10.2 million and consisted of four elements including Design Engineering, Demolition, Asbestos Abatement and New Construction. The project was bid in March 2005 with the majority of the work to be completed by December 31, 2005.

Project Details

The demolition portion of the contract consisted of the demolition and total removal of approximately 800,000 square feet of office and lab space requiring a number of different demolition methods. Building 25, a fifteen-story concrete Albert Kahn building, was removed with a ball and crane in conjunction with our hi-reach excavators. Building 209, an eight-story steel building, was tripped in sections in conjunction with our hi-reach excavators. A portion of this building had to be wrecked floor by floor as a portion of the building was to remain, including a portion of the basement under structure being removed above. We were also required to remove the top 3 floors of a nine-story building without damaging the floors to remain. The largest portion of the demolition began in July 2005 and was essentially complete in December 2005.

In addition to this work, the Owner gave us some additional work ($.8 million) to complete during this time period including the hand removal of a four-story boiler, the removal of a three-story commercial building and picking down in pieces a six-story bag house while the boiler house remained in operation. All work was completed safely and on time with no OSHA violations (3 inspections).

Asbestos abatement was started in May 2005 and completed in September 2005. The total asbestos contract totaled $2.7 million and involved three abatement contractors. At times we had more than 80 asbestos abatement contractor personnel on site daily. All work was completed safely and on time with no MIOSHA Air Quality Violations (2 inspections).
