|Tendering and Subcontracting
|17 October 1997
||The Housing Department
(HD) is the executive arm of the Hong Kong Housing
Authority (HA). HD invited tenders for piling
works on the Yuen Chau Kok site from contractors
on HA list of approved contractors. Twenty-seven
companies submitted tenders.
|28 November 1997
||The company finally
awarded the contract was Zen Pacific Civil Contractors
Ltd ("Zen Pacific"). They had submitted the lowest
bid-$63M. The works involved building the piling
foundation for five HOS buildings.
|10 February 1998
||The contract came into effect on 10 February 1998; however, Zen Pacific
subcontracted the piling works to another company, Hui Hon Contractors Ltd ("Hui Hon"). Zen Pacific would be responsible for procurement of materials, collecting 3 percent of their purchase cost and 4 percent of the contract price as administrative charges. The piling works for two of the buildings commenced immediately.
||Progress was slow; although Hui Hon later acquired a more suitable and powerful rig, the Bauer BG 40, a shortage of spare parts for this machine meant the temporary casings, which are used to support the soil on the walls inside pile shafts, could still not be driven right down to the very bottom of each shaft.
Lacking such support, the soil on the wall inside the shafts kept collapsing.
|May - July 1998
||To speed up the work,
two of Hui Hon's then directors
instructed workers to use a synthetic soil stabilizer,
Super Mud, instead of driving the temporary
casings down to bedrock. No approval was obtained
from HD for this change of method. The use of Super
Mud did nothing to improve the engineering outcomes.
Barely a month later, Hui Hon ran into financial
difficulties, and could no longer afford to use
|August - September 1998
||A number of Hui
Hon site staff had in fact already warned their
that substandard work was going on.. Instead
of heeding these warnings, the directors planned
a series of deceptive acts in order to conceal a
host of related irregularities. In early September,
Hui Hon reported that they had completed the piling
works for two of the HOS blocks.
|23 September 1998
||Since Hui Hon would not be able to complete the foundation works for the remaining three buildings on time, Zen Pacific took the upcoming works over, but continued to employ the same Hui On site staff for the project.
||Zen Pacific reported
to HD on 19 December that all the foundation works
under the contract had been completed. Three
days later, another contractor started to build
the superstructure. Zen Pacific was paid the total
amount of $57M for the foundation works1.
|27 July 1999
||Hui Hon was liquidated
in July 1999 and ceased operation in January 2000.
||Around this time, a number of scams related to substandard construction works came to light, and the public became alarmed.
HA decided to inspect the settlement condition of all the buildings in their projects.
|8 December 1999
|| The abnormal settlement
condition of two HOS buildings in Yuen Chau Kok
turned out to be particularly serious. HD therefore
appointed an expert to conduct an independent inquiry.
This confirmed that the settlement of these two
blocks was caused by short piling and was indeed
|23 December 1999
||HD lodged a complaint
with the ICAC on suspicion of corruption. Each
of the two buildings had by now been constructed
to a height of 33rd and 34th floors respectively.
|6 January 2000
|| Zen Pacific also lodged a complaint with the ICAC, alleging that corruption was involved in these works.
||ICAC swiftly mobilized 80 investigators to execute 21 search warrants and arrested eight people during two days of intensive operations on 8 and 9 January.
|9 January 2000
||HA announced that
they would suspend the construction of all superstructures for the two affected buildings.
|16 March 2000
||For safety reasons, HA decided to demolish the two affected buildings.
This took until June 2001.
|8 January 2001
||The two ex-directors
and a site agent
of Hui Hon were charged with dishonestly defrauding
HA from April to December 1998.
|11 October 2001
||The site agent
pleaded guilty and was sentenced to three and a
half years' jail.
|3 September 2002
of Hui Hon were convicted and sentenced to 12 years'
jail. They lodged an appeal and their sentences
were subsequently reduced by two years.
||HA lodged a claim
against Zen Pacific for losses amounting to $605
million. These included the costs of demolishing
the two buildings and the compensation paid to the
superstructure contractor. After four years of arbitration
lasting from 2000 to 2003, at legal costs of around
$40 million, HA reached an agreement with Zen Pacific
that Zen Pacific would pay compensation of $80
of the fact that the Project Quantity Surveyor( for valuation
and certification) had verified that Zen Pacific was not
entitled to the last payment claimed, and hence Zen Pacific
was only paid on ten occasions for the foundation works.
