For project enquiries, please contact Structural Engineering Services (SES) Division. The main services provided under this category are as follows:


The Company markets its own brand of Post-Tension system namely the Presscrete Post-Tensioning System (“PPS”). The Company has an in-house design team comprising experienced design engineers who are equipped with advance engineering softwares so that they can produce practical and cost effective PT solutions to its clients. Its PPS cable units are manufactured with strict quality control measures. The Company maintains a wide range of PT jacks and other PT accessories to suit various stressing conditions.


Structural Repairs, Strengthening and Maintenance

Once a structural problem is identified, the Company is capable of providing professional engineering advice on the steps to be taken to repair and strengthen these structures. Beyond advisory services, our company provides specialist engineering services to repair, strengthen and maintain structures employing methods such as grouting, guniting, high-pressure water jetting and epoxy plate bonding.

Grouting is a process whereby a fluid or semi-fluid cement slurry or a slurry made with other materials is pumped, injected or poured into voids to achieve certain enhanced properties. The process has wide applications especially in concrete repairs and strengthening, as well as in ground stabilization. The Company possesses a range of grout mixers and pumps and the skilled manpower to meet the needs of its customers.

Epoxy plate bonding is the process of adding steel externally to concrete using epoxy resins, thereby making it bond effectively to the concrete surface. This process is more cost effective in strengthening structures when compared to conventional methods such as using concrete and steel beams, as only a limited number of strategically placed metal plates need to be used. In addition, it is cleaner than conventional methods, and is particularly suitable in areas which are currently occupied.

Manufacturing, Installation and Replacement of Bridge Bearings

The Company manufactures, installs and replaces bridge bearings. Bridge bearings allow the relative movements of structural members of bridges. Movements occur as a result of changes in temperatures, weight and force. A bridge bearing primarily comprises of several profiled steel plates, an inner low-friction plastic plate and an inner circular rubber pad with brass seals around the pad. The Company manufactures bridge bearings under its own brand name, and the manufacturing process essentially involves three main stages; namely the design stage, the production stage and the assembly and quality control stage. In the design stage, the Company undertakes the design of the bearing based on project specifications. At this stage, the Company provides its expertise to arrive at an optimised design in terms of effectiveness and costs. In the production stage, the Company produces the parts of the bridge bearing. This production process encompasses machining, drilling and corrosion protection of the steel components and flat bars, cutting the brass seals to the right diameter, as well as shearing and cutting the inner plastic plate to the required size. In the assembly and quality control stage, the Company proceeds to assemble the components according to the design. Here, it ensures that it meets stringent quality control requirements. Once tested, the bearings are then packed and delivered to the site for installation. During installation, the Company provides value added engineering services by determining the type, size and quantity of the bridge bearings as well as the location at which these bearings should be placed.

Additional engineering expertise is required during bearing replacements, as the bridge would then be operational and alternative supports would need to be provided during the period when the old bridge bearings are removed and the new bearings put in place.


Structural Surveys

Structural surveys are conducted to test the integrity of structures during and after construction. Such surveys are required when the integrity of a building structure is suspect after it has suffered damage due to various reasons and may exhibit cracks, peeling of concrete and "honey combs", which are holes caused by pockets of air trapped in concrete. Surveys would also be required when a building is being renovated or when extensions are made. The Company uses a wide array of specialised equipment in its surveys. These include non-destructive testing equipment and techniques which employs ultra-sonic pulse velocity and electro-magnetic waves in order to test structures.



Guniting describes the process of spraying concrete mixtures at high velocitites as against the conventional method of placement of concrete by pouring. Gunite is free-form concrete and has wide application. It is used to stabilise soil surfaces and for encasement, strengthening and repair of defective structures. It is often used in underground work as well as for structures which have large surface areas and irregular shapes.

High Pressure Water Jetting

High-pressure water jetting is used mainly to cut and scarify or abrade materials and has several advantages when compared to the more conventional methods of drilling, hammering and hacking. Particularly for reinforced concrete it causes less damage to the structure’s reinforcing bars during scarifying or cutting., Cutting with water is also spark free. This is important in areas where there are highly flammable chemicals such as in oil refineries. The process is dust and vibration free. The Company has cut steel water pipes, cut steel plates, cut reinforced concrete and scarified spalling concrete with its 20,000 psi water jet machines.


Environmentally Controlled Demolition

The Company provides demolition services under controlled conditions such as minimal noise, force, vibrations and sparks. These services would be important in densely populated and highly built-up areas, as well as in areas where sparks or flames are not permitted. The Company owns hydraulic crushers, diamond saws, coring machines and high pressure water jets which are used to demolish structures under controlled conditions. Using our in- house technical expertise the Company formulates the pocedures and processes to ensure our controlled demolition work is safely carried out.
