(b) Electrical Engineering Systems
We are graded “L5” by the BCA. This enables us to take on electrical engineering works for
contract values of up to $10 million.
Electricity Distribution Systems
We design and install the electricity distribution systems for buildings. The electricity distribution
system comprises networks of electrical cables and equipment to distribute electricity from the
electrical sub-stations to the end users. We install the main switchboards which receive electricity
supply directly from the local utility provider, PowerGrid Ltd. We also install cables and connections
to electrical switchboards.
We also install high and low voltage switchgears and install earthing systems that would prevent
any dangerous over voltages or excessive current on devices that can conduct electricity. The
earthing system also provides a secondary means for lightning protection, remove excessive
electrical current and to reduce or eliminate power surges in household electrical appliances.

Board.
(d) Air-Conditioning and Mechanical Ventilation Systems
We are graded “L2” by the BCA which allows us to take on air-conditioning and mechanical
ventilation works of up to $500,000. Our ACMV services include the installation of air-cooled
split systems and mechanical ventilation systems. The air-cooled systems comprise of a
condenser and fan coils suitable for use in residential, commercial or industrial buildings.
Mechanical ventilation systems include car park ventilation and car park fume extraction systems.
We also install “fresh air” systems and space pressurisation or space exhaust systems. These
mechanical ventilation systems consist of fan, control components and ducting network.
