PROJECTS

ACAD Drawings and Engineering for moving gantry suited to cast-in-situ segmental bridges constructed by free cantilevering for M/s Phillip Holzmann, Germany.

Proof Checking of calculations for the 2 km long bridge crossing consisting of dual three-lane carriageway (2*15.05m). The Malaysian side structure is 1.75 km long and includes Low Level Viaduct, High Level Viaduct and Main Spans (96m + 165m + 96m = 357m). The Viaducts are constructed by precast segments in balanced cantilever, while the Main Spans are constructed by cast-in-situ free cantilevering. In collaboration with M/s HSSI, Malaysia.

Structural Design development for the 22 km long elevated part of the Light Rail Transit System II in Kuala Lumpur city. The scope of work included design development and detailed designs for the superstructure, sub-structure and foundations. Standard spans of various configurations and special crossings over major highways and other obstacles constitute the elevated structure. Factory-made precast box girder segments are used for the superstructure in conjunction with "dry" joints and external prestressing tendons. In collaboration with M/s HSSI, Malaysia.

Proof Checking of calculations for superstructure of the 186m long 3-span (50m + 86m + 50m) prestressed concrete continuous bridge constructed by cast-in-situ cantilever construction techniques. The cross -section consists of a twin-cell box girder for the 20.0 m wide deck. In association with M/s HSSI, Malaysia.

Proof Checking of calculations for the Approach Spans on each side of the main bridge (50.0m + 86.0m + 50.0m) consisting of 3-span continuous superstructures of 40.0m c/c of piers. The superstructure consists of 10 nos precast post-tensioned girders in each span for the 20.0 m wide deck. Continuity is established by casting in-situ the deck slab and end diaphragms of the girders. In association with M/s HSSI, Malaysia.

Of the 12 interchanges planned for Western Kuala Lumpur Traffic Dispersal Scheme, this interchange was the most complicated. The project comprises an elevated mainline with a 4-lane divided carriageway, five 2-lane ramps to permit smooth flow of traffic and a toll plaza. The design was carried out using BS Codes and loading included JKR's SV loads. The entire interchange was made using precast pre-tensioned M10/UM10 beams resting on single column piers with wide cantilevered pier caps. Foundations use 600 dia pre-tensioned spun concrete hollow piles. Small curved length in each ramp was designed using cast-in-situ RCC voided slab. Approach retaining walls were of reinforced soil. In association with M/s Zaidun-Leeng , Malaysia
