Intoduction

The Government of Malaysia intends to upgrade the existing Federal Route FT015 and B9 from Terminal 3 of Subang Airport to Sungai Buloh Hospital with approximately 12.0 km in length. The previous access to the Sungai Buloh Hospital is via the state road B9, a 2-lane single carriageway linked to the FT054 through a diamond interchange. It is also necessary to upgrade the state road B9 from Subang Airport FT015 to linkup FT002 with FT054 in order to improve traffic flow as heavy vehicles and other commercial vehicles heavily traverse the state road B9. In order to ease the traffic flow, as well as to cater for the future development, the contract “Cadangan Projek Menaiktaraf Laluan B9/FT015 dari Lapangan Terbang Subang ke Hospital Sungai Buloh” has been awarded to Perkim (Damansara Utama)-Rira Bina Sdn. Bhd. JV by the Government via Design and Build Contract comprise of Phase 1 and Phase 2. 2.2)

Description of The Problems & Possible Solutions

There are several problems that caused the extended period in project constructions:

Structure Component: DAMAGED OF L-SHAPE DRAIN AT SG. DAMANSARA RIVER TRAINING WORK The construction of L-shape structure for river training works were begin on February 2007 between Ch. 0m to Ch. 250m (LHS). The affected location by the major flood is on the down stream (LHS) of the river alignment.

The affected portion is between Ch. 80m to Ch. 125m (WB017 to WB026) which completed with the capping beam structure on March 2007. However, during heavy down pour dated 14/04/2007, sudden increase of water levels was happen due to accumulate volume from the up 18

PROJEK MENAIKTARAF LALUAN B9/FT015 DARI LAPANGAN TERBANG SUBANG KE HOSPITAL SUNGAI BULOH, SELANGOR DARUL EHSAN

stream section. The up stream section was widened by JPS’s project. The accumulate volume were flowing through the L-shape section at that time is under construction.

At the same time, it was created overflow condition on top of L-shape section. The problem arises when the existing river at down stream side yet to be widened by JPS’s project during incident. Hence, this situation was created the bottleneck and scouring action and damaged the portion of completed L-shape at down stream side especially at the bend with drain outlet discharge points.

CAST IN-SITU DECK RIB BEAMS AND SLAB CRACKINGS – (PROPOSED SG. BULOH EXPRESSWAY UPGRADING WORKS – MCAO) Issue Date : July 2005 The content of this problem deals with the cracking of cast in-situ rib beams and deck slab top cracking incidence observed on the Span 1 Left Hand Side deck slab from Abutment A to Pier 1. On the morning of 18 July 2005, the side formworks of the outer faces of the deck’s rib beams and cantilever flanges were stripped.

Several vertical crack lines were seen on both of the exposed surfaces. The finishing on the concrete surfaces were considered very good without obvious blemishes. Concreting of the said sections was done on the evening of 27th of June from approximately 6pm until 2am the following day. The total concrete volume in this single pour was 314m 3. The method of placing of concrete was by means of concrete pump. Thus, the average speed of concreting is almost 40 m3 per hour. The weather report during the whole concreting operation was reported as fine. The 20

PROJEK MENAIKTARAF LALUAN B9/FT015 DARI LAPANGAN TERBANG SUBANG KE HOSPITAL SUNGAI BULOH, SELANGOR DARUL EHSAN

concrete supply to site was considered consistent and supply trucks were delivering and discharging the loads in an orderly manner. The proposed concrete mix was of Grade 50 nominal strength with cement content of 460Kg/m3 and the water cement ratio is 0.37. The cube samples taken for this batch of concrete pour were sent for testing and the results for 7-days strength and 28-day strength were considered within the expected range. The average cube test results show that the 7-days strength was of average 44MPa while the 28-days strengths is not available as of this date.

The top surface of deck slab was sprayed with proprietary curing compound before the anticipated 2-hour setting time. However, some isolated crack lines were observed on the following day. The cracking patterns were in random and appeared to be fan-out shape. The surface cracks observed on the vertical faces of the exposed rib beams after formwork stripping is presented in Appendix A of this report. There were about 8-10 crack lines on each of the vertical surface. The crack lines are almost vertical, and the maximum crack width when measured on site is approximately 0.35mm measured by inspection with a transparent plastic marked with varying line thicknesses and superimposed over the crack locations. Most of the crack line extend from soffit to the underside of the cantilever flange, but some are discontinuous and less than 750mm long either near the soffit of the rib or near to the underside of the flanges. It is also observed that the first crack line started approximately at 5-7m from the either end of the stop ends.

Recommendations 25

PROJEK MENAIKTARAF LALUAN B9/FT015 DARI LAPANGAN TERBANG SUBANG KE HOSPITAL SUNGAI BULOH, SELANGOR DARUL EHSAN

Structure Component: Rapid drying of the concrete will significantly increases the possibility of cracking. The chemical reaction which causes concrete to go from the viscous or plastic state to a solid state requires water and heat is generated in the process. Shrinkage is a primary cause of cracking in freshly set concrete. As concrete hardens and dries, it shrinks. This is due to the loss of water through evaporation before the complete hydration has taken place. Rapid cooling of external surfaces and fast building up of hydration heat within the inner core creates a drastic thermal gradient across the concrete section. These two extreme phenomenon poses the greatest threat to undermine the weak tensile strength within the concrete. The effects of prestressing forces will tend to substantially close, if not complete, the cracks present on the rib surfaces. The recommendations are suggested as following below: 1. For the isolated cracks observed on the top of deck slab, it is required that liquid curing compound will still be applied after completion of concreting work but not more than 2 hours after pouring on any part of the surface. In addition, covering with plastic sheets or wet Hessian are proposed to lower the possibility of top surface cracking. It is recommended that these additional measures be carry out for at least 5 days continuously after concreting works. 2. It is proposed to control the speed of concrete placement carefully in order to minimize the amount of heat trapped inside of the rib core by allowing heat to escape freely over a reasonable larger open area. Timing of subsequent layer pour must not exceed the anticipated setting time of the previous poured and vibrated load in order to avoid the forming of cold joint across separately laid layers. 3. To limit the length of each pour operation to a smaller distance to reduce the possibility or quantum of cracking, if any, but on the other hand, also achieve reasonable work progress. 4. To carry out through inspection on the line and levels of formwork and falsework in order to reduce the external factors to it minimum.

26

PROJEK MENAIKTARAF LALUAN B9/FT015 DARI LAPANGAN TERBANG SUBANG KE HOSPITAL SUNGAI BULOH, SELANGOR DARUL EHSAN

5. After prestressing, majority of the crack lines will be closed due to the compression introduced to the rib. If cracks were not fully closed, it is proposed that high strength epoxy grout be injected into the cracks to seal it off completely.

Slope Component: Failure of slope stability such as landslides cause property damage, injury, and death and adversely affect a variety of resources. For example, water supplies, fisheries, sewage disposal systems, forests, dams, and roadways can be affected for years after a slide event. The negative economic effects of landslides include the cost to repair structures, loss of property value, disruption of transportation routes, medical costs in the event of injury, and indirect costs, such as lost timber and fish stocks. Water availability, quantity, and quality can be affected by landslides. Geotechnical studies and engineering projects to assess and stabilize potentially dangerous sites can be costly.
