Water Purification Works
Among the major treatment plant projects completed by the company are the Stage 1 and Stage 2 projects of the Sungai Selangor Water Supply Scheme which has a total capacity of 800 M.L.D. This is currently the biggest water treatment plant in South East Asia.

Water Distribution Works
Loh & Loh is responsible for laying many major distribution pipelines including the 70km pipelines of various sizes for two packages of the Malaysian Rural Water Supply Scheme, and a 30km of 2,050mm-diameter steel pipeline across rough and undulating terrain and urban areas for Packages C,D, and E of the Sungai Selangor Water Supply Schemes. Through the years, the company has also constructed more than 30 services reservoirs of various sizes, the largest having a capacity of 90 million litres.

With increasing pressures on the environment due to development, urbanization and industrialization, there is a growing need for effective flood mitigation measures to ensure safe and productive land usage.

The need to upgrade existing drainage and irrigation systems has been evident over many years. Loh & Loh’s civil engineering expertise as well as its fleet of land-based equipment have been put into good use in notable drainage projects. The company is involved in providing highly innovative logistics support and solutions to a wide range of drainage projects.

Loh & Loh has extensive practical and managerial experience in sewerage works. The expertise involves the design and construction of not only the sewering of properties but also pumping stations and pumping mains for an effective sewerage system.

Through decades of continuous growth, Loh & Loh has built up one of the biggest and most modern fleet of earth-moving and quarry equipment in the country. The fleet is capable of transforming any landscape at tremendous speed. The earth-filled dam projects completed by Loh & Loh involved the movement of vast volumes of earth and other materials. Its strength and expertise with earthwork was demonstrated by its successful and timely completion of the EW100 and EW200 Bulk Earthwork Projects for the development of Putrajaya Core Island. This important project involved moving and relocating 17 million cubic metres of earth and 1 million cubic metres of rocks in just 20 months under stringent environmental and logistical constraints.

Loh & Loh has also established a good reputation in the Building Construction sector. The company completed the construction of two 30-storey condominium blocks at the Games Village in Bukit Jalil in the Klang Valley and the Yayasan Saad Matriculation College at Lembah Beringin in Selangor. Both were fast-track projects. The entire campus of the Yayasan Saad Matriculation College including staff and students quarters and the sports complex, was completed in seven months from earthwork formation to full completion of all facilities.

Loh & Loh prides itself on its involvement in the construction of the first dual carriage vehicular bridge on Penang Island. Other highway projects include the participation in the Penang Island Traffic Dispersal Scheme, the extension of Jalan Duta road in Kuala Lumpur and the construction of Linggui Dam access in Johor.

Another project undertaken by the company is the Kuala Kangsar Railway Bridge over Sungai Perak. The scope of works in the contract involved the design and construction of a 250-metre long pre-stressed concrete bridge and the refurbishment of the century old Victorian Bridge.

In the early 1980s, Loh & Loh undertook reclamation work for Phases I & II of the Penang Bridge Project which involved both the Penang Island and Prai Interchanges. One hundred hectares of reclaimed land on the island were rehabilitated using 2.5 million cu. metres of hydraulic filled materials dredged from the sea.

With rapid development and increasing land pressure, the coastal areas increasingly have to be rehabilitated to meet existing as well as new requirement or needs. The completion of several marine, coastal and off-shore projects have given Loh & Loh considerable experience and expertise in dredging and reclamation works.

Loh & Loh’s role in the construction of golf courses and landscaping include earthworks, shaping, drainage, irrigation, turfing, beautification, landscaping and the construction of ponds and infrastructure. Its involvement in these activities is a reflection of the company’s expansion in its scope of civil engineering expertise and also as a response to market needs.
