Cadangan Projek Jalan Lingkaran Tengah II – Pakej 11 (MRR2)
Conclusion and Recommendation, concerning the Cracks in Crossheads
The longitudinal cracks are not a negligible problem of torsion during construction.
The lack of transverse reinforcement is a safety risk for the final stage.
The calculated safety factor is far below 1.0.
Internal redistributions of forces and alternative load paths due to yielding of the reinforcement, intensively cracking and plastification of compression zones of the concrete prevented a collapse so far.
The structure is not stable.
Emergency and safety measures should urgently be undertaken. deformation measurement and installation of strain gages at transverse reinforcement is recommended.
Please inform your client about our serious concerns.
best regards

The above is the letter from the German Consultant to our Malaysian authority.
Did you all know how serious it was at that time in 2004? This letter was written to our govt in August 2004.
The Government did not treat it as a matter of crisis. It took the govt until February 2006 to decide to take action. They didn't care about preventing the possibility of catastrophic failure as reported by Dr Robert L. Vollum of Halcrow. They don't care about thousands of people that will be dead of this catastrophic failure occurs.
Only after Dr Wahid was appointed as the Director-General of PWD did he pushed for the repair and remedial work to be completed within 3 months.
The group of JKR engineers together with the workers worked 24 hours each day for more than 90 days. They work in 2 shifts - 12 hours each shift to meet the target set by PWD.
They did complete the repair works, all within 3 months. Samy Vellu was surprised how they managed to do it. But he never said a word of appreciation until today.

Look at the pictures below:
These pictures were taken at 3am in the middle of the night.Each night the German senior engineer from Leonhardt, Andra & Partner (LAP) together with the JKR senior management and JKR engineers would meet at the project site to discuss the works schedule, the details and the problems encountered. More than 90 litres of grout was pump into the concrete beams to grout the understrength porous concrete.
Where were you at 3am? Were was Samy at 3am? You may be surprised that the D-G of JKR was there most of the nights (i.e. early hours of the morning around 3am) with the workers at MRR2 site.
These are the people who work 24 hours a day for 90 days to repair the MRR2. They completed the works in 90 days.

What were the recognition for these people?
Why was the govt not thankful and appreciative of their commitment, contribution and sacrifices.
They were living for 3 months without spending time with their family members. They had to abandoned their wife, children and parents so as to ensure that the MRR2 repair works are completed within the 3 months.
And at the end, there was not even a word of thanks from the Works Minister Samy Vellu nor from the Prime Minister and Deputy Prime Minister. Today, all of them lives in obscurity after serving the nation.

The PM and DPM showed tremendous concerned for Saiful; but they didn't even cared for the a group of people who had sacrificed for the nation - these were the heroes who work hard to prevent a catastrophe from occurring.
Note:
The flyover is safe. Only Pier 28 has some problem with the plastic straps which are used to encased the grouts used to seal the pre-stressed wire-ropes which provides the necessary reinforcements to strengthen the crossbeams which had failed. The repair for the defective works are in progress and the consulting engineers from LAP have inspected the defects and recommended the necessary repair.
Incidentally, Pier 28 was the first Pier that was repaired in 2006. As such, there may had been some initial problem due to the learning process as the repair contractor is not experienced in this methodology of structural strengthening works. Immediately after observing the contractor's weakness, JKR utilized a team of senior engineers to closely monitor the quality of works and ensured that the remaining works meets the strict specified requirements.

===================================
Most enlightening sentence in the whole article.
We can't have PM and DPM with misguided concerns running the country.!!
Moo_t & Artchan,
Thanks for your support and empathy.
well, they started the problem of course they should work hard to cover up the shit......
like contractor renovate yr house with shoddy work and you complained, of course they have to work OT to rectify the mess they caused.
mav
what do you expect? at the height of the floods down south, our PM was having a jolly good time in Down Under.
the rest, monkey see monkey do, no?
Denzook,
The people who are repairing the works are not the consortium contractors of the project.
This project is Design-and-Built and the supervision is done by Maunsell, not JKR.
We have to discern the parties of the wrong and those who are correcting it and appreciate the efforts; not lump them together.
Very good information, maverick.
Thanks.
we are too busy with Anwar case,The Terengganu's mercs car,the by-election,the muzakarah/muqabalah etectec until we forgot that there unsung heroes that need to appreciated!
a round of applause and standing ovation for them!
People have short memories. They failed to realize the hard works & situation that professionals have to go through in difficult times. Sometimes, for just some small mistakes you will be curse unforgivenly.
Look at the ways the RMK-9 projects are being thrown to civil servants to be implemented, rushing, no time for planning & thus sacrificing the quality.
Rest assure that in the rush of delivering these projects there are bound to make mistakes & errors.With short of staff & facilities compared to the amount of works. Does anybody care of their suffering now?
When something goes wrong, the whole world will go after them. Else who cares who are you?
saiful's ass is of importance to the leaders of teh country and they are doing their best to take care of it. but hell with the thousands of malaysians whose life may have been dangered by this snafu. Hell ty even denied initially it was a design problem and Samy was going to sue anyone who said so.
well done to the DG and team. Malaysians thank you.
Kittykat46,
Thanks for the compliment. You are welcome.
rejected joe,
Yes; we must appreciate those heroes.
rocky,
Appreciate your compliment and admiration for the hard work of JKR staff and engineers.
