Architectural Construction Site Manager

THIS IS A CONSTRUCTION SITE ROLE — NOT A DESIGN POSITION

If your background is in architectural design or interior design studios, this is not the right fit

About DayOne

Review method statements for architectural works and ensure compliance with project quality and safety standards

Lead and manage the First-of-Kind (FOK) programme for architectural works

Manage contractors and subcontractors across all architectural systems: façades, fire doors, waterproofing, interior finishes, and ironmongery

Maintain 3-week rolling plans and coordinate sequencing across trades

Lead authority inspections and ensure Thai regulatory compliance

Report weekly on progress, delays, and defects via ACC

Requirements

8 to 15 years of on-site construction management experience

Degree in Architecture, Construction Management, or Civil Engineering — or equivalent site management experience

Proven hands-on expertise in façade and cladding, waterproofing, fire doors and roller shutters, and interior finishes (walls, floors, ceilings)

QA/QC program management on active construction sites

Strong hands-on site experience coordinating multiple subcontractors under fast-track construction schedules
