As far as I concern, Ulu Jelai Hydroelectricity Project to be completed by 2014. Are we confident this project can be fully commissioning 3 years from nowaday? I am not sure but will update later on if I have the information. But I still believe they can manage it.

TNB awards RM2.15bil jobs for Ulu Jelai project
PETALING JAYA: Tenaga Nasional Bhd (TNB) has signed two agreements worth some RM2.15bil for its Ulu Jelai hydroelectric project.
The company said the first agreement was with SMEC International Pty Ltd and SMEC (M) Sdn Bhd consortium, which would provide detailed engineering design for the main civil works, engineering design review for electrical and mechanical works, project management and site supervision.
The contract value was A$22.1mil and RM31.1mil, which was equivalent to RM99.6mil at the prevailing exchange rates, it told Bursa Malaysia yesterday.
The second agreement is with Tindakan Mewah Sdn Bhd and Salini Costruttori SpA consortium. Under this contract, the consortium will be responsible for the main civil, electrical and mechanical works.
The main civil works consist of the construction of a dam, two water-transfer tunnels and an underground power house.
TNB said the electrical and mechanical works involved the design, manufacture, erection, testing and commissioning of two power generation plant, each with a capacity of 186MW, and the associated electrical and mechanical equipment.
It said the value of the second contract was 307 million euros and RM818.1mil, which was equivalent to RM2.05bil at the prevailing exchange rates.
The company said the contract period for the development of the Ulu Jelai hydroelectric project was five years, during which the payment to the contractors would be made in accordance with the progress.
The project cost will potentially result in an increase in TNB's net assets by about 7.1%.
TNB said the project was expected to be completed by July 2016.

Hydojet Blasting
Hydro jetting and Hydro blaster equipment is used to direct high pressure streams of water against a surface to clean or cut the material. The steams of water released by hydro jetting and hydro blasting equipment can exceed 10,000 psi. hydro jetting and hydro blaster equipment is used for cleaning or demolition of products made of metal, wood, concrete, stone, plastic, glass or other building materials.
Specific components within a hydro jetting or hydro blaster equipment system include abrasive injectors, pressure generators, blast cabinets or booths, water guns, and water tanks. Plunger-type intensifier pumps are commonly used to generate high pressure water for water jet cutting, wet or water abrasive blasting and non-abrasive pressure washing or rinsing. Crankshaft driven plunger pumps are also used for pressure generation.
Usually crankshaft driven plunger pumps may be more efficient in electrical energy costs compared to intensifiers, but at high pressures (>20,00 psi, 137 bar) seals must be periodically replaced. Crankshaft driven plunger pumps also provide a virtually ripple free pressure source in comparison to intensifiers. An accumulator may be required to smooth out pressure fluctuations if an intensifier pump is used. In air based blast or jet systems, air compressors are typically used to generate pressure which add heavy running cost.
Water guns or lances are the apparatus within hydro jetting and hydro blaster equipment that directs the stream of water through a nozzle and at the appropriate region of the work piece.
The water tank or hopper is used for storage of water, cleaning agents, blasting media or abrasive-water slurry mixtures.
