4 Phases — URS to PQ

A structured engagement model that aligns with regulatory expectations and reduces validation risk.

01

URS & Concept Design

Drafting the User Requirement Specification, conceptual layout, classification map, airflow regime selection (unidirectional vs turbulent), and process-flow alignment with HVAC zoning.

02

Detailed Design & Coordination

Coordination between process, HVAC, architecture and facility teams. HEPA/ULPA terminal placement, differential pressure cascade, return air strategy, material/personnel flow.

03

Construction Support

On-site quality oversight during build, coordination with installation contractors, tracking against Design Qualification, change control management, and documentation hand-off.

04

Qualification & Validation

Installation Qualification (IQ), Operational Qualification (OQ), Performance Qualification (PQ) protocol guidance. Particle count certification, recovery testing, environmental monitoring strategy.

Regulatory Standards We Work To

ISO 14644-1 / 14644-2

Airborne particulate cleanliness classification (ISO Class 5 through 9), continuous monitoring strategy, and recovery testing protocols.

EU GMP Annex 1 (2022)

Sterile manufacturing requirements, contamination control strategy (CCS), grade A/B/C/D zoning, and Annex 1 compliant facility design decisions.

21 CFR Part 11

FDA electronic records and signatures compliance, audit trail design, and documentation aligned with US pharmaceutical regulatory expectations.

cGMP — Current Good Manufacturing Practice

Facility classification, qualification protocol structure, and ongoing operational compliance for pharmaceutical manufacturing environments.

Validation Master Plan (VMP)

Drafting and review of the Validation Master Plan, qualification matrix definition, and risk-based qualification approach (ICH Q9).

Last Planner System

Lean construction methodology applied to pharmaceutical projects — on-time, on-scope delivery from Design Qualification through PQ release.
