"High standards have been set for the assembly work. About 60 quality control technicians are employed to check the quality of components and ensure that the assembly work is up to the required standard," said Mr Yeung.
For example, the tolerance level in the accuracy in length for each 18-metre long deck unit is only plus or minus six millimetres.
Four assembly lines have been established at Shatian according to the sequence in which the units will be erected. Assembled units are arranged in such a way that the first unit in each line will also be the first ones shipped to Hong Kong for erection.
To facilitate transport, the lead unit in each line is assembled closest to the jetty on site. These units will be taken from the "head" of a line to the jetty by special multi- axle carriers.
These carriers are also used to move units at the assembly area to make sure that the end unit of a line properly fits the front unit of the following line.
Erection will start from the middle of the main span and work towards the towers of the Tsing Ma Bridge. Erection of side span elements will be sequenced with the main span to balance loads on the tower.
"Erection of the first section for the suspended deck of the bridge is expected to take place this summer," Mr Yeung said.
Work on the 2.2-kilometre bridge is being undertaken by the Anglo Japanese Construction Joint Venture under a $7.14 billion contract. The joint venture's sub- contractor. Argos Engineering and Heavy Industries Co Ltd, is responsible for the assembly work at Dongguan,
