DLT were sub-contractors for installation of a new 40.75m high 3115 tonne furnace line in Taiwan. Our scope included full engineering of all temporary works required together with supply of jacking equipment and site labour to carry out the work. The blast furnace was delivered to the site in 8 segments, weighing up to 477 tonnes each, which were lifted and skidded into the furnace house before being jacked vertically and aligned for welding. These operations were carried out using a mix of strand jacks and climbing jacks. More>
Heathrow
Airport, Terminal 5 building and air traffic control tower, UK
DLT were responsible for the detailed erection engineering for the 18,500 tonne steel roof structure of the new main core terminal building, and for a 1000 tonne air traffic control tower. Both were fabricated off-site and erected on-site using strand jack lifting systems. The roof box girders, purlins and cladding to the core terminal building roof was erected in 6 No 2,000 tonne lifts. The control tower was pre-assembled off-site into 7 fully complete modules and then assembled on-site using a unique vertical jacking technique. More>

Wembley National Stadium, UK
DLT were responsible for the detailed connection design and erection engineering for the 26,000 tonnes of structural steel, including stands, cable suspended roof and main arch structures. The 1,490 tonne main arch was assembled flat and rolled up into position using strand jacks. We were responsible for detailed design and site supervision this heavy lifting operation. More>

Hong
Kong Convention & Exhibition Centre.
DLT were responsible for erection engineering, heavy lifting equipment supply & operation for the erection of an 8000 tonne prefabricated roof structure and a 5,500 tonne link bridge. The roof structure was fabricated and assembled in the Philippines into modules weighing up to 460 tonnes each, which were then shipped to the site for lifting and skidding into final position. The link bridge was erected piece small by a stiff leg derrick mounted on a purpose made skid track. Access to this part of the site was very restricted, requiring the stiff leg derrick to construct its own skid track and then work backwards along the skid track to erect the permanent works. More>

HAECO
hanger roof lift, Hong Kong
DLT were responsible for the design, supply and operation of a strand jack lifting system together with associated erection engineering to lift 2 No pre-assembled roof sections, each weighing over 1000 tonnes. Each section of roof was lifted with 9 No DL-S185 strand jacks. Temporary works for the lift comprised 3 No 300 tonne capacity jacking towers, plan bracing to stabilise the roof and a guide track against the concrete core structure. More>

HQ1
Building, London
DLT were responsible
for detailed connection design and erection engineering of the 6,600 tonnes
of steel frame to this 16 storey office block. This included heavy lifting
of a 650 tonne module which was built on a lower floor and then raised
30m to the 16th floor. DLT were also responsible for supply and operation
of the strand jack system to carry out this lift, using 4 No DL-S185 strand
jacks.
Cairns
Convention Centre Phase II, Australia.
The roof to this convention centre is constructed from a complex series of curved V shaped steel trusses that work with a plan tie system in the finished state to provide a rigid and stable structure. To reduce the roof erection cost and programme, the roof was assembled in fully clad panels adjacent to the site and erected onto temporary supports within the building. We were responsible for the detailed erection engineering of the roof, including all temporary supports and stability bracing, which was required to withstand cyclone wind loads at any erection stage
