World Demolition Awards 2023 - Contract under US$1 million shortlist
PROJECT: Villa Maria, Lot 1
CLIENT: ENGECO SAM
This project consisted of the complete renovation of the Villa Maria, located on the Boulevard d’Italie in Monaco. Due to the site’s urban location, its close proximity to other buildings and the client’s need to preserve the structure’s front elevation, Despe chose to dismantle and deconstruct the structure from the top down.
After completing stripping out works, the contractor erected protective scaffolding with sound-absorbing panels to protect neighbouring properties and businesses, and deconstructed the building using compact machines that weighed less than 3 t each, (max 3tons). The top-to-bottom deconstruction project also saw Despe undertake excavation works to a depth of 25 m.
Erith Contractors, United Kingdom
PROJECT: South Shields Gasholder
CLIENT: Northern Gas Networks
This challenging project entailed the demolition of the redundant 137-year-old gasholder in South Shields. The gasholder was constructed of riveted steel with cast iron columns and steel lattice work and had become a local landmark in South Shields over the decades. Over 600 tonnes of recovered metal was recycled at a local facility in Middlesbrough.
The most demanding aspect of the project was the confined site footprint and the proximity of the gasholder structure to the boundary of the site and the neighbouring supermarket and retail outlets. This was overcome through collaboration with South Tyneside Council to arrange for a temporary road closure to allow a MEWP to operate from the road, while the crane conducted lifting operations within the site. Due to the busy location, the road closure took place for ten consecutive nights ensuring compliance with the client’s key dates.
Jet Demolition and Edifice Engineering, South Africa, India
PROJECT: Precision brownfields coke oven demolition
CLIENT: Tata Group - Tata Steel Jamshedpur Works
Jet Demolition, working with Edifice Engineering of Mumbai, was contracted to remove two coke ovens and the associated equipment at Tata Steel Jamshedpur Works in India. Jet Demolition carried out the explosive induced collapse of the major structures, which included two 110-m concrete chimneys and a 49 m tall, 6,000-t elevated coal bunker.
P Olesen, Denmark
PROJECT: Demolition of crane and hopper in 48 hours
CLIENT: Ørsted Bioenergy & Thermal Power
In May of 2023, P Olesen undertook the dismantling, cutting and disposal of a heavy coal crane, which measured 50 m high and weighed 350 t, and a 100-t unloading hopper at Avedøre Power Station in Copenhagen. P Olesen used a floating crane for the lifts from the sea side, as well as a floating barge to transport the crane and hopper directly for scrapping. This enabled the structures to be removed in just 48 hours. The dismantling was done without interfering with the operation of the plant or activities in the quay, which had an operational conveyor belt running beneath the crane.
Thompsons of Prudhoe, United Kingdom
PROJECT: Pulverising Coal Injection (PCI) Plant, Redcar
CLIENT: STDC (Teesworks)
Thompsons of Prudhoe was contracted to remove a Pulverising Coal Injection (PCI) Plant at the former Redcar Steelworks site, situated on the Northeast coast of the UK.
Installed later in the Redcar Blast Furnace’s lifespan, the PCI Plant was modern unit that had housed milling equipment and large pulverised coal storage silos, and as such, was to be sold after its removal. Thompsons of Prudhoe first carried out extensive decontamination works to the PCI Plant, which comprised a steel frame structure clad with profile sheeting measuring approximately 18 m wide by 40 m long, and 60 m high.
The PCI Building was located on the northeast coast of the UK and subject to coastal weather conditions with winds often measuring between 40-70mph.
The PCI plant project required good collaboration, forming of good relationships and close interface management with neighbouring contract companies to permit and control access for the safe completion of the works.
