Helping construction companies deliver accurate quantity take-offs, competitive estimates, and successful projects through engineering expertise and attention to detail.
Ericson Viernes is a licensed Civil Engineer based in Tarlac, Philippines, specializing in civil estimating and quantity take-offs for residential, commercial, and subdivision developments. His work sits between the drawing board and the job site — turning construction plans into accurate Bills of Quantities, competitive estimates, and schedules that hold up once construction actually begins.
Since entering the field in 2020, he has moved through on-the-job training, field engineering, project engineering, and project management before focusing on freelance civil estimating — carrying a site engineer's read on buildability into every take-off he prepares.
A career path that moved through field engineering and project management before settling into full-time civil estimating — each role sharpening the read on what a drawing actually costs to build.
