Every tower needed to be rigorously dismantled, together with associated piping, stairs, hangers and supports, all the way down to prime of concrete dike slab. It was crucial that the concrete slab of the dike not be damaged as this was going to be re-utilized for brand new development. The work also needed to be performed with the utmost attention to safety for employees and the surrounding facility employees and close by constructions. Lively strains and structures had been on all sides of the work space and in addition in close proximity to an energetic plant street with pedestrian and vehicular traffic.
Prior to any dismantling work being carried out, several essential pre-dismantlement duties wanted to be accomplished. All utilities and lively strains to the cooling towers have been isolated and made protected. Asbestos containing supplies have been properly eliminated and abated. As safety was paramount, chain hyperlink fencing with green screen mesh was placed around the work area. As well as, debris netting was placed in strategic locations to ensure no debris landed outdoors the work zone.

A safety video was watched by all workers and every worker was instructed on the correct PPE required for the undertaking. Beyond the fundamental Level D PPE, excessive visibility security vests were worn by all workers. In addition, a JSA (job safety analysis) was developed and applied for each day of work.
Dismantling of the two cooling towers started with the salvage of the fans for re-use and spare elements.

Following the equipment salvage, the inside of the dike for the cooling towers was cleaned of piping and all diffusers. This selective demolition was carried out prior to any structural demo to make it easier to maintain materials segregated for clear up and recycling.
Because of the proximity to active traces and structures, mechanical demolition utilizing excavators could not be carried out. In order to safely take down the cooling towers, R. Baker & Son developed a methodology to utilize expert dismantlers in personnel lifts with hand tools. A 60 and eighty ft. (18 and 24 m) Genie personnel raise was lifted into the diked space using the a hundred-ton capability crane.

As a section was demolished, debris was instantly removed using Bobcat S150 and S185 skid steers with demolition buckets. This process continued till the concrete and steel base of the models was reached.
To demolish the concrete and steel beam bases, R. Baker & Son once again utilized the Grove 100-ton capability crane to fastidiously lift tools into the diked area. Two Bobcat 341 mini excavators with concrete breakers and buckets had been utilized for this phase. These machines simply demolished the cooling tower bases into rubble whereas not damaging the slab under, which was to be utilized for the brand new construction. The demolished concrete was loaded out of the diked space for offsite recycling.
