What H&H Engineering and Maintenance does

H&H Engineering and Maintenance Pte Ltd is a Singapore-based private limited company that delivers integrated construction, demolition, landscaping and building maintenance services to clients within Singapore. The firm operates three core service lines: Construction & Engineering (planning and execution of projects for residential and commercial structures), Demolition & Landscaping (site clearing combined with landscape design and ongoing maintenance), and R&R including A&A Works (Repair & Redecoration plus Addition & Alteration, covering inspections and routine building upkeep such as fixture replacement, hinge oiling, floorboard replacement, AC filter changes and lock replacement). Service delivery is supported by a headcount of 11–50 staff, comprising engineers, Environmental Control Officers (ECOs) and technical specialists.

The company is registered with Singapore's Building and Construction Authority (BCA) under three Workhead classifications — CR01 (Minor Construction Works), CR03 (Demolition) and CR09 (Repair & Redecoration) — which together define its licensed scope. It holds ISO 9001:2015 (quality), ISO 14001:2015 (environmental) and ISO 45001:2018 (occupational health and safety) certifications, alongside Bizsafe Level 3 status from Singapore's Workplace Safety and Health Council. Headquartered at 320 Serangoon Road, #10-09, Centrium Square, Singapore 218108, the firm was also recognized with the STIE Best Contractor Award in December 2024.

The business operates a project-based, quote-driven revenue model with no publicly disclosed pricing or recurring contract structure. Customer acquisition is handled through the corporate website (hhengr.com), basic social media channels (Facebook, Twitter, WordPress) and direct engagement via phone, email and contact form. Operations are confined to Singapore; no overseas markets are served. The only publicly identified customer is the Gurkha Contingent, for whom the firm performed general Repair & Redecoration works at 9 Vernon Road, Singapore — indicative of public-sector or institutional client work alongside undisclosed private engagements.
