On the Tseung Kwan O – Lam Tin Tunnel works, concrete had to be placed around marine piles above the water. We designed a set of formwork platforms that hang from the piles on steel beams. Each platform carries its own working deck, hinged curved formwork panels and edge protection, and can be lowered into position, opened, struck and moved to the next pile.
From the drawings
We also designed and installed temporary steel platforms of 62 and 90 tonnes on the existing Ø610 mm casings over sea caissons CS4 and CS18. The caissons were first cleared of marine growth and deposits, the rough edges of the casings cut off, and the existing steel collars removed and refitted to form a catch platform.
