World Demolition Awards 2024 - Contracts Over US$1m Shortlist
ERITH
COUNTRY: United Kingdom
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 which 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 pre-tensioned.
A selection of drawings showing the unusual construction were discovered post-tender. 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 highlights:
• Water jetting to create inspection holes to better understand the pre-tensioning.
• Coring to understand the structural integrity and degree of contamination inside the internal gasholder. Knowing the structural integrity of the tank lid was essential to allow the lid to be used as a dismantling platform.
• A bespoke demolition sequence, using steel road plates with weights to prevent sudden steel release or ‘pings’.
• Dismantling of the outer structure with a robotic track saw to gradually release the structures tension and containment of the sludge.
• Erection of a bespoke scaffolding screen across two boundaries with debris netting to prevent projectiles.
• Responding to neighbours vibration concerns, a vibration ‘break trench’ was created and pre and post works structural survey offered to neighbours as reassurance.
• The outer concrete tank wall was crushed on-site and sustainably used as backfill material.
• Donation to the local Community Centre.
The Deal project was awarded the Best Strategy Implementation at the National Grid Property Awards in 2024.
INDEPENDENCE DEMOLITION
COUNTRY: United States
PROJECT: Progressive Field Ballpark Improvements
CLIENT: M.A. Mortenson Company and The Cleveland Guardians
The Cleveland Guardians, a storied Major League Baseball franchise, and their home, Progressive Field, have been central to downtown Cleveland since 1993.
Integral to their legacy, Independence Demolition (ID) played a key role in both the construction and recent upgrades of the stadium. The 2023-2024 renovations, part of the “Progressive Field Reimagined” project, aimed to modernise the ballpark and enhance the fan experience.
In 2022, ID, in collaboration with Independence Construction, M.A. Mortenson, and the AKA Team, began significant renovations to Progressive Field.
The project included transforming Upper Concourse seating into communal areas, converting the Terrace Club into a Beer Hall, and constructing a new kitchen and commissary. These upgrades were executed in phases to minimise disruption during the Guardians’ regular season, requiring precise planning and engineering.
During the 2023 season, ID undertook the demolition and modification of existing structures to prepare for new construction, involving two, 300-ton crawler cranes performing 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.
ID completed over 50,000 man-hours of work without incidents, which ID says highlights their commitment to safety and excellence.
These efforts promise a revitalised Progressive Field, blending historic charm with modern amenities, solidifying its status as a cherished landmark in Cleveland.
LIBERTY INDUSTRIAL
COUNTRY: Australia
PROJECT: Thevenard Island Onshore Decommissioning
CLIENT: Chevron Australia Pty Ltd, operator for the Thevenard Island JV
Liberty Industrial was engaged by Chevron Australia to deliver decommissioning and remediation activities as part of the Thevenard Island Onshore Decommissioning Project.
Thevenard Island is located 22km off the coast of Onslow in the Pilbara region of Western Australia. This project successfully restored the landform of the lease area to a condition similar and compatible with the adjacent nature reserve.
The scope included project management, engineering, procurement, decommissioning, remediation and rehabilitation earthworks, logistics, and waste management coordination, involving extensive activities such as demolition, soil amendment, and reuse of construction materials.
Liberty Industrial decommissioned and demolished Chevron Australia’s facilities, including storage tanks, pipelines, and infrastructure. Advanced methodologies, such as drone technology, provided unparalleled detail and accuracy in capturing site conditions, expediting data collection and improving project visibility.
The project faced significant challenges, including accommodation and transport limitations, volatile weather, and strict COVID-19 quarantine restrictions.
Despite these hurdles, Liberty Industrial managed logistics effectively, using rotating staff rosters and sea travel for equipment transfers.
Environmental regulations were strictly adhered to, with measures in place to protect native fauna and flora, ensuring compliance with environmental plan requirements.
Sustainability was a key focus, with extensive recycling and waste management efforts. Liberty Industrial coordinated 58 barge movements to remove scrap materials, demonstrating a strong commitment to environmental conservation.
Successfully completed in October 2023, Liberty Industrial says the project not only achieved its goals efficiently but also set a precedent for managing environmental and logistical challenges in remote locations.
PRIESTLY DEMOLITION INC
COUNTRY: Canada
PROJECT: UF6 Building 27, Cameco Conversion Facility
CLIENT: Cameco Corporation
Deconstruction of the UF6 Building 27 at the Cameco Conversion Facility was a complex project that required extensive planning and communication to safely process and catalogue every single piece of material contained on the footprint of the B27 structure.
This project was a hugely successful project for both Cameco and Priestly Demolition. Consisting of a seven-storey tower and two smaller two-storey building sections with a total footprint of 72,800 sq ft this heavily contaminated structure sat idle at the Port Hope Conversion Facility for decades prior to the deconstruction.
It was clear from the beginning that this would not be a standard demolition project due to the nature of its former operation and the legacy waste stored over the decades. New procedures had to be developed to ensure radiological, conventional, and environmental safety.
Priestly says: “The B27 deconstruction project serves as an example to the demolition and nuclear industries that with careful planning, flexibility, creative thinking, patience, timely communication and genuine care and dedication for the safety of the crew—it is possible to safely dismantle and dispose of a complex radioactive structure such as the UF6 Building 27.”
The Cameco Corporation is a world leader in uranium production and is a major supplier of uranium processing services required to produce fuel for the next generation of clean energy. The Port Hope Conversion Facility produces uranium hexafluoride and uranium dioxide as well as manufacturing fuel bundles utilized in the CANDU reactors.
This undertaking is known as the Vision in Motion project, an opportunity that was made possible because of the Port Hope Area Initiative project and Canadian Nuclear Laboratories.
TOTAL WRECKING & ENVIRONMENTAL
COUNTRY: United States
PROJECT: McIntosh Station Units 1, 2, and 3
CLIENT: Lakeland Electric
After three bid events and much evaluation, Total Wrecking was chosen as the contractor of choice on this project over the lowest bidder, due to its experience and safety record.
Total Wrecking was contracted to abate and demolish units 1, 2 and 3 at the CD McIntosh Station.
The scope of works included the demolition of pipe racks, clarifier tanks, circulating pipes, cooling towers, intake structures, plant wastewater tank and additional equipment removals, coal yard railroad and tunnel, coal conveyors, precipitators, office buildings and out structures, stack, boilers, SCR, scrubber and turbine structures.
The works, which are still ongoing, will see concrete from the site downsized to specification for backfill and, at the end of the demolition phase, the site will be restored for the new build of the RICE Power Plant Project - which is happening in tandem with demolition operations on some areas of the site.
Major challenges involved in the project include Total Wrecking’s crew having to work while the Lakeland McIntosh Power Plant site in is live operation, as well as in and around active overhead transmission lines.
The site, which is divided by a roadway, is also in close proximity to a Sensitive Ecosystem, comprising wetlands, lakes and the Tenoroc Public Nature Preserve, all of which require protection from the environmental impact of the works.
