Foundation works

Foundation works form the lowest and supporting parts of most construction works in Hong Kong. Quality of foundation works is essential to the safety of buildings, as superstructure works are constructed over and performed on top of the foundation works. Problems of sub-standard piling works affect building safety.

Foundations can be classified as shallow and deep foundations, depending on the depth of load-transfer from the structure to the ground. The definition of shallow foundations varies according to different standards. In Hong Kong, embedment depth of three metres (3 m) is generally adopted to define shallow foundations. Bored piles, socketed H-piles and mini-piles are more commonly used foundation works methods in Hong Kong.

Foundation works delivered by our Group include bored piles, driven H-piles, socketed H-piles, mini-piles, footing foundation and pile caps. Different foundation works are used depending on the superstructure to be constructed (e.g. high-rise buildings against small structures), nature and occurrence of rocks and soils at the construction site, environmental protection consideration, neighbourhood of the construction site, costs and other features.

Civil engineering construction

In the discipline of civil engineering, we provide site formation works, landslip preventive and remedial works to slopes and retaining walls, and road works and drainage services:

Site formation

Site formation works are performed to prepare a construction site for subsequent works for foundation and superstructure. They generally involve the clearance of construction site, demolition of existing structures, excavation to the design formation and/or basement level, reduction and stabilisation of existing slopes, and associated infrastructure works (which include construction of road, drainage, sewage and water works).

Landslip preventive and remedial works to slopes and retaining walls

LPM works involve slope stabilisation and upgrading works, which include engineering inspection, retaining wall and check dam construction, cut and fill slope, soil nailing, rock dowel and rock bolt installation, flexible barrier construction, surface drainage construction, slope surface treatment with high pressure grouting and spraying and landscaping.

Roads and drainage works

Roads and drainage works include construction of road interchange, carriageway and walkway, footbridge and traffic link bridge, road improvement and widening works, flood prevention works, construction of drainage channel, outfall pipe, box culvert and pumping station, and associated landscaping, utilities diversion as well as electrical and mechanical works.

General building works

We act as main contractor in general building projects. We also undertake as sub-contractor projects of alteration, renovation, and fitting-out of existing buildings. We focus on providing building services to local property developers which generally require a high standard of service quality.
