Govt approves MTR plan for 80 checks in Hung Hom

[GeoTommy]

Number of tests is way too little: Michael Tien - RTHK

"You're checking 0.6 percent of the total number of couplers, which is totally unacceptable by any professionals who know anything about statistics and sampling,"

'Checking 80 spots in Hung Hom station pointless' - RTHK

"One percent is certainly not enough and the government and the MTRC has to give us more details about how it arrived at this suggestion of inspecting less than 1 percent of the reinforcing bars. Otherwise the whole exercise will be futile."

Dump MTR's 'farce test' at Hung Hom, say lawmakers - RTHK

The police had unscrewed the bars manually to measure the embedded length instead of using ultrasound used by the MTR and came to completely different results.

after 40 days of conducting these tests, the people are being told that the method used is not reliable.

Ngai said records like these do get misplaced during large scale construction projects. But usually there will be multiple copies which will distributed among different parties involved in the process.

He said he believes in this case, some people may have destroyed the records on purpose as no copies seem to exist.

of course, MTR should have done that, but their position was there is no problem. ultrasound could work if they exposed the couplers and scanned them, that should reveal any airspace. However, it appears from photos they did not, the coupler is still deeply embedded and encased in concrete....
