What mentabuild does
mentabuild is a Bangkok-headquartered construction consultancy firm providing three integrated service lines: Cost Management (Quantity Surveying), Project & Construction Management, and Environmental Advisory. The firm serves real estate developers, hospitality operators, government and institutional clients, and industrial/manufacturing customers across Thailand and the broader Southeast Asia region, with active coverage in Myanmar, Cambodia, and Laos. Notable mandates include full pre- and post-contract cost management for One Bangkok (~1.4 million m2), ICONSIAM, the Queen Sirikit National Convention Center, the Ritz-Carlton at One Bangkok, The PARQ (LEED Gold certified), and Forestias North Plot. The firm traces its origins to 1984 when it was established as LECE (Langdon Every Cost Engineering), pioneering quantity surveying services in Thailand; it subsequently operated under the Langdon Seah and Arcadis Thailand brands before being divested by Arcadis in 2022 and rebranded as the independent mentabuild.
The business operates on a professional services model: fees are project-based, quote-driven, and tailored to scope, complexity, and duration, with multi-year engagements typical for landmark developments. Revenue is generated through direct enterprise sales targeting major developers, hotel operators, and institutional clients, with client acquisition driven by professional networks, referrals, and competitive tender processes. The firm employs approximately 76 staff at its 6/F Kian Gwan Building II headquarters on Wireless Road in Bangkok, supported by a senior management team including a Managing Director, multiple Directors overseeing Cost Management, Finance, HR, and Business Development functions, and practice leads across Project & Construction Management and Environmental Advisory. Service delivery is anchored in technical expertise — quantity surveying, commercial due diligence, loan drawdown monitoring, programme management, contractor procurement, site supervision, BIM Management, Technical Due Diligence, and Environmental and Social Impact Assessment — rather than in proprietary software or technology platforms.
The firm's go-to-market emphasizes relationship-led enterprise engagement, thought leadership through industry workshops (including a December 2024 facade engineering workshop with Meinhardt Indo-China), and demonstration of expertise via landmark project delivery and credentials such as the RLI International Outlet Centre New Build award for Siam Premium Outlets. Post-2022, mentabuild has pursued regional expansion into Indochina markets, broadened its service portfolio to include BIM and Technical Due Diligence, and initiated academic partnerships to support workforce development. The firm is privately held, management-led following the Arcadis spin-off, and incorporated as Mentabuild Company Limited in Thailand.
