PROJECT Deal Gasholder Demolition
CLIENT National Gid Property Holdings
Despite Erith’s experience demolishing over 100 gasholders, the Deal gasholder presented a number of unique challenges that it had not previously encountered.
The structure was found to contain an earlier gasholder tank inside it and the outer concrete tank was found to be pretensioned.
A selection of drawings showing the unusual construction were discovered posttender. This triggered a complete change in approach. Erith overcame the many complexities and challenges requiring a dynamic programme and adaptive methodology to safely achieve the project objective. ■

PROJECT UF6 Building 27, Cameco Conversion Facility
CLIENT Cameco Corporation
Deconstruction of the UF6 Building 27 was a complex project that required extensive planning and communication to safely process and catalogue every single piece of material contained in the B27 structure.
Consisting of a seven-storey tower and two, two-storey building sections, the 6,760 sq m structure was previously used to produce uranium hexafluoride and uranium dioxide. Highly contaminated, it sat idle for decades prior to its deconstruction.
Priestly Demolition developed new procedures had to ensure radiological, conventional, and environmental safety. ■

PROJECT Progressive Field Ballpark Improvements
CLIENT MA Mortenson Company and The Cleveland Guardians
Independence Demolition carried out demolition and modification of existing structures at Progressive Field - the home of The Cleveland Guardians Major League Baseball franchise, as part of a renovation and upgrade project.
The works were executed in phases to minimise disruption during the Guardians’ regular season, requiring precise planning and engineering.
Independence undertook the demolition and modification of existing structures to prepare for new construction. It saw two, 300-ton crawler cranes perform over 700 picks in less than two months, and the removal of significant structural elements.
Meticulous execution and engineering ensured on-time completion without incidents, despite the challenges of working within a confined urban environment. ■

TOTAL WRECKING & ENVIRONMENTAL
COUNTRY United States
PROJECT McIntosh Station Units 1, 2, and 3
CLIENT Lakeland Electric
Total Wrecking was contracted to abate and demolish units 1, 2 and 3 at the CD McIntosh Station in Florida.
The works included the demolition of pipe racks, clarifier tanks, circulating pipes, cooling towers, intake structures, a wastewater tank and additional equipment removals. With the site divided by a roadway, the contractor also had to remove a coal yard railroad and tunnel, precipitators, office buildings, outstructures, a stack, boilers, and turbine structures. Total Wrecking’s crew had to work while Lakeland McIntosh was in operation and in areas with active overhead transmission lines.
The site was also close to wetlands, lakes and the Tenoroc Public Nature Preserve, all of which required protection from the environmental impact of the works. At the end of the works, which are still ongoing, the site will be restored for the building of the RICE Power Plant Project. ■
