About
Chart makers who came up through site sheds, not slide decks
Registered business
Official name: Ridgebase Analytics Co., Ltd.
Established: 2016
Registered office: Lee Hyerin, 63 Dongan-ro 13-gil, Anyang-si, Gyeonggi-do 14000, REP. OF KOREA
Ridgebase Analytics was founded in 2016 by two former site engineers who spent years translating daily manpower counts into cumulative curves for owner meetings. We registered as a limited company in Anyang after repeat requests from Gyeonggi-do contractors who wanted outside chart preparation without hiring full-time QS staff.
How we work
We treat every engagement as a document-handling assignment, not a software rollout. Your site administrator continues using the forms and apps they already know. We receive exports—PDF daily reports, Excel payment logs, schedule PDFs—and return chart sets formatted for print and projection.
Our Anyang office holds no construction licenses. We do not supervise trades, certify quantities, or sign off on safety. That boundary keeps our role clear for owners and lenders: independent visual reporting from data you already produce.

Values we hold on site visits
- Accuracy over speed — A delayed Friday chart with verified numbers beats a rushed curve with guessed percentages.
- Readability — If a director needs a glossary to understand a chart, we redraw it.
- Confidentiality — Contract values and subcontractor rates stay within the assigned analyst team.
