The Holland House Hotel project was a massive alteration and refurbishment project on an existing 16 storey concrete framed structure acquired from the Chartered trust Group.
A major alteration for the new hotel was the total demolition of an existing 2 storey extension structure which consisted of heavily reinforced concrete walls, huge concrete panels and 800mm thick reinforced support beams and upright columns.
The 2 storey extension itself was approx 30.0 mtrs x 15.0 mtrs square and was built on top of an existing basement car park area. With this in mind the main contractor faced a massive demolition problem with a 1.5 ton weight restriction applicable on the ground floor slab. Additional logistical problems faced by the main contractor were the close proximity of main roads and neighbouring office buildings.
To overcome all these logistical problems Denver Construction Services were consulted and awarded the demolition contract which was to be undertaken with the use of diamond cutting methods and Brokk Robotic machine demolition techniques.
Diamond floor saws and track wall saws were used to detach the 2 storey extension from the main building and hydraulic bursters were used to break up the 800mm thick support beams and columns.
A Brokk 150 3 Phase Robotic demolition machine (which met the 1.5 tonne weight restriction) was then lifted up to the roof slab of the extension via craneage and then placed through a pre cut hole in roof slab onto the 1st floor area.
Complete with crunching jaws and demolition pecker, the Brokk 150 enabled Denver Construction Services operatives to successfully demolish the entire building extension area within the required contract period time.
The success of this project led to further phases of the project being awarded to Denver Construction Services.
