What site teams say after the first owner meeting
The rebar delay in week eleven showed up clearly on the S-curve. Our owner asked why we had not flagged it earlier—we had, but only in text logs. The chart made the conversation shorter.
— Choi Seung-ho, Site Director · Anyang office-retail build
Ridgebase accepted our messy Excel exports without complaint. Took them two cycles to learn our trade naming, which was fair. By month three the Friday PDF was part of our routine.
— Yoon Hae-jin, Project Admin · Bundang apartment complex
Good charts, though I wish the first onboarding visit had been scheduled earlier—we lost a week waiting for the baseline schedule import. Once running, delivery has been reliable.
— Kang Myung-soo, GC Project Manager · Ilsan mixed-use
We used the milestone variance set for a foundation phase only. Cost was reasonable and the bank accepted the PDF without requesting a second format.
— Lim Soo-yeon, Owner Rep · Pyeongtaek logistics centre
Case: Suwon residential tower — third draw submission
18-storey residential · 22-month programme · Monthly ledger retainer
Han Ji-won, representing the building owner, needed cumulative cost evidence before the lender released the third construction draw. The general contractor's internal spreadsheets mixed committed and invoiced amounts, which the bank reviewer rejected twice.
Ridgebase received six weeks of subcontractor payment requests and the approved CPM schedule. Within three working days we delivered a cumulative cost curve, trade table, and one-page variance note explaining a MEP subcontractor invoice that had arrived ahead of physical progress.
The draw was approved on the second submission. Han continued the monthly retainer for the remaining fourteen months of construction. The GC's site admin now sends logs every Thursday; Ridgebase delivers charts every Friday by 17:00.
Case: Anyang retrofit — envelope phase variance
Office retrofit · Envelope milestone only · One-time chart order
A tenant-fitout contractor needed to show the landlord why curtain-wall installation lagged the interior schedule by eleven days. Rather than a full retainer, they ordered a single envelope-phase variance chart.
Park Min-seo plotted planned vs actual installation squares against the baseline, annotated three weather-delay days and a glass delivery hold, and joined a 30-minute call with the landlord's engineer. The dispute closed without legal escalation.
