What is the primary objective of **WELL**?

**The primary objective of WELL is to design, operate, and verify buildings that advance human health and well-being through evidence-based performance outcomes.** Administered by the International WELL Building Institute (IWBI), WELL v2 structures requirements across **10 concepts**—**Air, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind, and Community**—plus **Innovation**. It mandates **24 Preconditions** (pass/fail minimums) and enables points from **102 Optimizations** for certification tiers: **Bronze (40 points)**, **Silver (50 points, min 1 point/concept)**, **Gold (60 points, min 2 points/concept)**, **Platinum (80 points, min 3 points/concept)**. Unlike efficiency-focused standards, WELL prioritizes occupant metrics like **CO₂ ≤900 ppm** via on-site verification.

Who is legally or professionally required to comply with **WELL**?

**WELL is voluntary with no legal mandates, but professionally required for organizations pursuing certification across new/existing buildings, interiors, or portfolios.** Applicable to owners, developers, and operators via pathways like **WELL Certification** (owner-controlled), **WELL Core** (≥75% leased base buildings), and **WELL for Residential**. Corporate real estate, facilities, HR, and ESG teams in offices, healthcare, education, hospitality drive adoption for tenant demands, productivity, and ESG reporting. No employee/revenue thresholds; billions of sq ft certified globally.

Does **WELL** require an external audit or third-party certification?

**Yes, WELL mandates third-party documentation review and on-site performance verification (PV) by authorized WELL Performance Testing Agents.** Process includes IWBI platform enrollment, scorecard development, two review rounds (preliminary/final), and PV testing air, water, light, sound, thermal comfort at ≥50% occupancy. Pre-testing recommended; continuous monitoring pathways allowed for features like **A03 Ventilation (CO₂ ≤900 ppm)**. Certification awarded post-verification; conflict-of-interest rules prohibit dual consulting/testing roles.

How often should an assessment for **WELL** be performed?

**WELL requires recertification every three years, with annual reporting for monitoring features like air quality.** Ongoing assessments via continuous monitoring (e.g., **A08: ≥1 monitor/325 m²**, recalibrate annually, update displays every 15 minutes) and periodic testing support compliance. Precertification optional for design validation; full PV during initial certification and recert.

What are the consequences of non-compliance with **WELL**?

**Non-compliance results in certification denial, curative review fees, delayed timelines, and no WELL designation.** Failed **Preconditions** block all tiers; PV failures (e.g., exceeding pollutant thresholds) require remediation or appeals. No statutory fines, but lost ESG value, tenant abatements, reputational damage, and recertification ineligibility occur. Operational drift risks failed recertification.

Can **WELL** be mapped to other international frameworks?

**Yes, IWBI provides official crosswalks mapping WELL features to frameworks like LEED.** Alignments reduce duplication (e.g., air filtration, materials); **Skybridge** tool maps v1-v2/addenda. Enables dual certification for integrated ESG strategies without redundant evidence.

What is the first step to begin implementing **WELL**?

**The first step is project enrollment/registration on the IWBI digital platform and scorecard development.** Identify pathways, baseline **Preconditions**, target tier, and gaps via pre-testing (e.g., air near highways, water in old pipes). Form cross-functional team (facilities, HR, design).

What is the primary objective of **AS9110C**?

**AS9110C's primary objective is to define quality management system requirements for aviation maintenance, repair, and overhaul (MRO) organizations to ensure consistent conformity to customer, statutory, and regulatory requirements while enhancing customer satisfaction through continual improvement.** It builds on ISO 9001:2015's high-level structure (Clauses 4-10), embedding aerospace-specific controls for configuration management, counterfeit parts prevention, human factors, traceability, and risk-based thinking (Clauses 6.1, 8.1.1) to support continuing airworthiness in safety-critical environments.

Who is legally or professionally required to comply with **AS9110C**?

**AS9110C applies to MRO organizations providing maintenance services for commercial, private, and military aircraft, including repair stations, component overhaul facilities, and OEM MRO divisions.** Certification is often contractually required by OEMs, airlines, and regulators for supplier qualification and OASIS listing; it harmonizes with FAA/EASA Part-145 but does not supplant regulatory approvals, licenses, or ratings.

Does **AS9110C** require an external audit or third-party certification?

**Yes, AS9110C requires third-party certification through accredited registrars following a two-stage audit process.** Stage 1 reviews documentation and readiness; Stage 2 verifies effective implementation via on-site evidence of operational controls, internal audits, and management review after at least three months of QMS operation.

How often should an assessment for **AS9110C** be performed?

**Internal audits for AS9110C must be conducted at planned intervals based on process risk, with higher frequency for critical maintenance processes like configuration control and release-to-service.** Annual surveillance audits follow initial certification, with full recertification every three years; management reviews occur regularly, using performance data from audits and KPIs.

What are the consequences of non-compliance with **AS9110C**?

**Non-compliance with AS9110C risks regulatory sanctions like FAA/EASA Part-145 certificate suspension, fines up to $100k per day, contract termination, and litigation from airworthiness failures.** It leads to market exclusion from OEM/airline bids, reputational damage, AOG events costing millions, and failed supplier audits.

Can **AS9110C** be mapped to other international frameworks?

**Yes, AS9110C uses ISO 9001:2015's Annex SL high-level structure, enabling direct clause mapping to compatible frameworks.** IAQG correlation matrices support alignment with regulatory standards like EASA/FAA Part-145 for integrated QMS without duplicating controls.

What is the first step to begin implementing **AS9110C**?

**The first step is a disciplined gap analysis mapping existing processes to AS9110C clauses, including regulatory requirements and prioritized risks.** Secure executive sponsorship, define QMS scope, and produce a phased project SOW with clause-to-process matrices, RBT worksheets, and internal audit prerequisites before certification.
