Primega Construction Engineering is a small Hong Kong construction subcontractor focused on two services: soil and rock transportation, and foundation-related construction works. The core business is hauling excavated soil and rock from construction sites to government waste disposal facilities, landfills, or other sites that can reuse the material as fill. Primega Construction also sells excavated rock to processors who convert it into recycled aggregate. A secondary and growing business involves acting as a subcontractor for excavation and lateral support works and bored piling, leveraging the company's existing machinery. Primega Construction operates entirely as a subcontractor, engaged project-by-project through invitation to quote rather than active sales. Customers are primarily foundation and site formation subcontractors working on private sector projects in Hong Kong, and customer concentration is high, with top customers accounting for roughly 85–89% of revenue. Contracts are priced on a cost-plus basis, either as lump-sum fixed prices or at fixed unit rates per volume or weight. Key profit drivers include excavation volumes in Hong Kong, government waste disposal charges, fleet utilization, and the ability to divert materials to recycling channels to reduce disposal costs. Primega Construction owns a fleet of 45 tipper trucks, which it argues provides better cost control than competitors relying on leased equipment. The company also trades biodiesel as a small secondary activity. Growth strategy centers on expanding the truck and excavator fleet, moving into excavation services directly, and adding project management headcount to handle larger projects.
