Hi !
Your cost, schedule, and take-off partner. I help contractors and owners bid clean and stay on budget.

Clean numbers beat pretty slides. If you need a BOQ, a quantity take-off, or someone to hold the baseline, let's talk.
Cost that cannot be traced is not control. It is a guess written neatly.
Three tracks at once: employee, open for project work, and teaching engineers.
Cost Estimator at PT Asuka Engineering Indonesia. Pre-bid, quantities, and budget across civil, mechanical, electrical, and instrumentation.
Estimating, BOQ review, and project control for contractors, owners, or EPC teams that need numbers they can stand behind.
Founder of Kelasteknik.id. Primavera P6, SAP2000, and cost estimating for engineers who need to work, not just collect a certificate.
General contractor across civil, mechanical, electrical, and instrumentation. Pre-bid lead on Coats Rejo, awarded at IDR 39 billion. Clients include Black & Veatch, FMC, and OTE.
40+ renovation projects at once. Baseline, vendor contracts, and spec QC. Rework down 60%.
Haul-road design, culverts, cut and fill, and the Canopy Galatama Kohod project in Tangerang.
I want to go deeper in Oil & Gas and EPC cost engineering, bring AACE discipline to energy projects, and keep Kelasteknik as a place where engineers learn tools they actually use on site.
A loose take-off makes every rate behind it a lie. Quantity comes first.
An estimate without notes is an opinion. Assumptions, exclusions, and risk have to be visible.
A schedule or cost that is not locked cannot be controlled. Progress without a baseline is just a story.
