Process & QA/QC

We Don't Just Check Models. We Govern Digital Delivery.

NETTMS operates a structured 5-Level Digital Quality Governance Framework — similar to regulated industries — where no drawing, model, or report is released without multi-layer clearance, traceable approval, and documented version control.

“Zero-compromise quality is not a policy. It is the only way we work.”

5-Level Quality Screening

Every Deliverable Passes Through All Five Levels

Level	Performed By	What Is Checked	Gate Outcome
Level 0Producer Self-Check	BIM Modeler / Engineer	Scope compliance, naming conventions, LOD verification, basic clash review, drawing sheet integrity, quantity sanity check	File moves to Level 1 OR returned for correction
Level 1Discipline Lead QA	Discipline BIM Lead	BEP alignment, parameter & data consistency, cross-discipline interface check, model health (warnings/corruption), view & template consistency, sheet set verification	Approval to coordination review OR return with comments
Level 2Coordination Validation	Coordination Manager	Clash detection (Navisworks/ACC), interdisciplinary tolerance verification, RFI & issue resolution tracking, coordination matrix alignment, construction feasibility logic	Models are coordination-ready OR clash list issued
Level 3Digital Compliance Audit	QA/QC Head / Senior Reviewer	Client deliverable compliance, contract scope mapping, LOD/LOI validation, IFC/export integrity check, drawing-to-model consistency, report accuracy	Deliverable matches agreed client terms OR revision required
Level 4Release Authorization	Authorized Release Authority	QA checklist signed, revision numbering validated, ACC/CDE version control confirmed, client format verified, delivery log created	Official Digital Release Certificate issued with Release ID

Release Principle: No drawing, model, or report is released to any client or stakeholder without completing all five levels above. Every released deliverable carries a unique NETTMS Release ID, an approval trace, and a digital release log maintained within the controlled CDE environment.

Zero-Compromise Principles

NETTMS Quality Principles — Non-Negotiable

Non-Negotiable Quality Standards

No direct file release to client without QA clearance

No model without multi-discipline coordination screening

No drawing without model validation and sheet integrity check

No revision without documented change log and approval trail

No compromise on agreed LOD, scope, and deliverable format

No uncontrolled file sharing outside the CDE environment

No single individual produces, reviews, and releases the same deliverable

🇮🇳 India vs Global — Before & After BIM + ACC

Metric	Global	India
Cost Overrun (pre-BIM avg.)	+28–80%	+30–50%
Schedule Overrun (pre-BIM avg.)	+20 months	+25–40%
Rework as % of project cost	5–15%	12–18%
BIM Cost Saving (documented)	5–12%	8–15%
Schedule reduction with BIM+ACC	7–15%	10–20%

“Large Indian infrastructure projects average 30% cost overrun and 25–40% time delay. BIM adoption in pilot programmes reduced both by 10–20% in the first year.”
— KPMG India — Engineering & Construction Survey 2022

“Projects that integrated BIM with ACC Build saw 20–25% reduction in rework, 15% faster delivery cycles, and near-zero drawing conflicts at site.”
