Why Manufacturing-Backed BIM & Architecture Outperforms Pure Drafting Bureaus

Registered on November 27, 2008, sermimar.com stands at the digital and engineering root of an architectural, structural, and industrial manufacturing group whose contracting heritage dates back to 1980 and formal engineering governance to 1997.

Unlike software-only BIM outsourcing shops disconnected from physical construction, SerMimar® operates within a vertically integrated ecosystem of 25+ manufacturing and EPC brands—spanning roll-formed S350GD structural steel, Class A1 fiber-cement cladding, EN 12810 scaffolding, and cast-iron hearths. Every Revit family, Tekla connection node, and curtain-wall bracket we detail reflects real factory tolerances and crane erection logic.

ISO 19650 QUALITY ASSURANCE

3-Gate Engineering & Zero-Clash QA/QC Protocol

GATE 01 · BEP & DATUM LOCK

ISO 19650 Common Data Environment & Survey Coordinate Alignment

Before modeling begins, true UTM/National Grid survey coordinates, shared parameter files, element LOD matrices, and container naming conventions are locked across all four disciplines.

GATE 02 · AUTOMATED ZERO-CLASH

Navisworks & Solibri Hard-Clash (±3 mm) & Clearance Verification

Structural penetrations, curtain-wall slab-edge anchors, gravity drainage invert slopes, and HVAC maintenance zones pass automated clash rules until zero unresolved BCF issues remain.

GATE 03 · PARTNER SIGN-OFF

Seismic Drift, Hygrothermal Envelope & 5D BoQ Audit

Prior to CDE Published status, our founding architect and civil engineer audit inter-story seismic drift compatibility, EN ISO 6946 condensation safety, and 5D schedule accuracy.

Who is the legal operating entity behind SerMimar.com?
SerMimar.com is officially operated by CFY Mühendislik Mim. Dan. Yapı Malz. İnş. San. ve Tic. Ltd. Şti. (Tax ID: 2091289512, MERSIS: 0209128951200001), headquartered in Maltepe, Istanbul, Türkiye, within the Yağmahan Holding industrial ecosystem.
Who leads the technical sign-off on architectural, structural, and interior BIM packages?
Every commission is directly governed by our three founding partners: Architect İdris YAĞMAHAN (Masterplanning, Envelope & BIM), Civil Engineer Celalettin YAĞMAHAN (Seismic Structural & Steel Statics), and Interior Architect M. Furkan YAĞMAHAN (Hospitality/Villa Spatial BIM & Acoustic/Fire Partitions).
When was the SerMimar® digital brand established?
The root domain sermimar.com was registered on November 27, 2008, building on group contracting roots dating back to 1980 and formal engineering practice established in 1997.
Can international clients visit your Istanbul HQ and Gebze industrial manufacturing corridor?
Yes. Overseas developers, architects, and procurement directors regularly visit our Maltepe Istanbul studio for live Navisworks BIM coordination workshops combined with factory inspections in nearby Gebze–Dilovası OIZ.
What quality assurance gates apply before drawings or BIM models are issued?
Every milestone passes a 3-gate internal QA/QC protocol: automated Solibri/Navisworks zero-clash verification, structural seismic drift and bracket check, and ISO 19650 parameter audit prior to CDE upload.
