Central Heating and Power Plant (CHPP) Demolition, Joint Base Elmendorf Richardson (JBER), Alaska

CEI performed the complete site investigation and characterization, hazardous-waste remediation, abatement, demolition and site restoration of a coal fired power plant built in the 1950s consisting of 8 boilers and a large coal storage and train car thawing building.  Unique aspects of this project included the complete removal of the foundation that extended more than 40’ bellow the surface where contaminated ground water was encountered at 8’ bellow the surface.  CEI provided all of the engineering, contaminated water control, contaminated soil work and facility demolition.  Ground contamination was resultant of both above ground and underground storage tanks as well as PCB containing transformers all of which were removed as part of this project.  Further complicating demolition was the presence of PCB and lead containing coatings on most all surfaces including the concrete foundation.  These contaminated coatings had to be removed prior to demolition.  Asbestos containing materials were also present throughout the facility and had to be abated prior to demolition. The boilers were also found to contain Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM) that required special handling and disposal during demolition.  CEI developed and built several specialized pieces of equipment during this project to safely and productively perform the abatement and demolition work through an Alaskan winter and adjacent to military housing development.

Flint Hills Refinery Demolition, North Pole, Alaska

CEI performed abatement and demolition of the Flint hills refinery and bulk fuel storage facility on 87 acres in North Pole Alaska. CEI performed testing and abatement of hydrocarbons, Mercury, asbestos, lead, PCB and solfolene from the facility prior to demolition. CEI drained, abated and demolished towers, tanks, piping and related equipment and facilities throughout extreme winter conditions with zero safety incidents. CEI provided all salvage, material handling, disposal and recycling on the project. This project was delivered with no changes ahead of schedule.

Knik Arm Power Plant, Anchorage Alaska

CEI performed abatement, interior selective demolition and renovation into office space and recycle facility of a former 1950’s era coal fired power plant.  Four boilers and turbines were removed by hand from the inside of the structure to gut the facility for build out.  The turbine room was renovated into office space.  The exterior 4 acre coal storage yard was cleaned up and hardscaped into a modern recycle transfer facility.

Removal of Trans Alaska Pipeline Pump Station 10

CEI performed the abatement and demolition of Pump Station 10 including, storage tanks and camp facilities. This large scope of remote work was successfully performed in one short summer season with zero accidents and no impacts to the active Trans Alaska Pipeline.  Alyeska Pipeline Service Company awarded CEI the Atigun Award for Contractor of the Year for this project.

Rocket Launch Facility, Kodiak Island, Alaska

Selective demolition of the explosion damaged 180’ tall rocket launcher unit. Due to the critical nature of this project, CEI was tasked with performing the demolition on an expedited schedule under very harsh winter conditions. The project included working at heights up to 180’ under sometimes brutal weather conditions, winds up to 60 MPH, blinding snow storms, limited daylight hours, temperatures down to -20 F. all on a very tight schedule . CEI not only succeeded, but we exceeded all expectations using innovative solutions to safely perform the work on time and on budget.

Demolition of Hangers, Ft. Wainwright, Alaska

This project was performed on the airfield taxiway apron area of an active military airfield. Due to the active use military airfield, the demolition had to be performed in a very controlled manner with absolutely no demolition debris allowed to blow off the site. The 80” hangars, had to be demolished in a manner that captured all debris within the hangar footprint. CEI used high reach excavators with specialized demolition tools to carefully control the demolition process. Despite encountering some of the most inclement weather in 50 years, CEI succeeded in meeting all of the project requirements on schedule and without incident.

Donjek River Bridge, Yukon Territory, Canada

Demolition of an 1850 Feet long bridge including concrete piers, cofferdams and abutments. There was a limited window of time to perform the pier and cofferdam demo work within the river due to fish restrictions. CEI developed an innovative method of lowering major bridge sections for use as temporary bridge access, to perform the demolition of the in-water structures without impacting the river, and provided a significant cost savings to the Owner. CEI was the first U.S, contractor to receive the Yukon Territories, Certificate of Recognition for safety. The project was completed safely and ahead of schedule.

Sharpe Army Depot Demo, Stockton, California

Demolition of 1.6 million SF of structures containing large amount of asbestos, lead based paints, and other regulated hazardous materials that had to be removed from the buildings prior to demolition. CEI self- performed all of the utility disconnects and re-routing of new utilities for the project. There was a substantial amount of heavy concrete demolition as some of the structures, had heavily reinforced foundations. All concrete was crushed and re-used on site. CEI achieved an 85% recycle rate for this project. We completed this project a year ahead of schedule with no safety incidences.
