With Sri Lanka experiencing significant growth in infrastructure development coupled with increasing tourist arrivals, the local office of Anhui Shui’an Construction Group Ltd. (ASCG) recently held a project completion event for its innovative gravity sewer system at the Shangri-La Hotel, Colombo. 

ASCG, a leading China-based enterprise focusing on the general contracting of construction work and integrating commercial investment, real estate development, hospitality, tourism, scientific incubation, factory building leasing and international businesses, will lay new sewer lines to cater to the new developments with no dig (micro tunneling) technology for newly-built and upcoming hotels based in the city’s Slave Island area.

Micro tunneling is a modern technology that is new to Sri Lanka when it comes to constructing sewers and ASCG has taken up the Colombo Municipal Council sewer project as its entry point to sustainable development in the country. This sewer technology will immensely benefit large-scale hotel development in the area. 

With the enormous support by the Deputy Municipal Commissioner Eng. Lalith Wickramaratne, Directors of Engineering Division Eng. Nihal Wickramaratne and Eng. Salim including others, ASCG through challenging difficulties and unforeseen congestions was able to successfully complete a micro tunneling project on time to Shangri-La Hotel Colombo which was opened immediately after its construction. 

The pipe jacking by micro tunneling involved pipes of different sizes and materials. The pipes used were vitrified clay jacking pipes up to diameter of 600 mm and reinforced concrete jacking pipes up to a diameter of 1,200 mm.

Eng. Nihal Wickramasinghe, speaking at the event, said: “It was a difficult task considering the site conditions, especially without sufficient details of underground structures inside the army camp along Baladaksha Mawatha. During the micro tunneling process the machine even struck a concrete pile foundation which we thought was a draft foundation. It was really a highly challenging task and I take this moment to thank ASCG for all their efforts to complete this.”

ASCG’s motive in Sri Lanka is to share and merge modern technology in China with locally available ones to implement projects in the most cost-effective and sustainable way. With a registered capital of RMB 560 million and a competitive edge in the global construction marketplace, ASCG today has around 16 immediate subordinate departments including IT, survey and design, investment management and overseas business development amongst others. 

ASCG has been granted the super grade qualification by the Chinese Government for general contracting of water, hydropower and building works and grade-I for general contracting of municipal works. The group has been certified as class-I for safety standardisation and rated by the China Construction Industry Association as an AAA-Credit enterprise.

With its corporate philosophy ‘Honesty, fine works, initiative, innovation and social contribution’, ASCG consistently pursues its development strategy of ‘Reform to advanced development, innovate operation and to drive lean management’, strengthening its construction initiatives throughout China and heading to the world.

ASCG will continue to forge ahead with determination, continuous innovations, excellent equipment, start-of-the-art technologies, scientific management and the utmost sincerity to cooperate with all sectors of society to share win-win developments and target fruitful achievements.
