Response-Time SLA
Every inquiry receives an acknowledgment within 24 hours. Drawing reviews return a baseline proposal within 48 hours. Project updates are issued weekly during active phases. These are not targets — they are contract terms.
Service Commitments — What You Can Expect from Hanart
A facade contract is only as reliable as the commitments behind it. These are the service standards we apply to every project — from first inquiry to final handover — backed by 1,000+ projects, six Luban Prizes and ISO-certified management systems.
Three Pillars
The commitments that define the contract
Quality Assurance
ISO 9001, 14001 and 45001 certified management systems govern every stage. Six Luban Prizes — China's highest construction quality honor — confirm that our discipline sustains across project scale, type and geography.
Single-Point Responsibility
Design, fabrication, installation and aftercare under one contract, one project manager, one quality system. No subcontractor chains, no responsibility gaps, no coordination failures between trades.
Service Level Details
Stage-by-stage commitments
These standards apply to every Hanart contract, regardless of project size or location.
| Project Stage | Commitment | Standard |
|---|---|---|
| Inquiry & RFI | Initial acknowledgment of inquiry | Within 24 hours |
| Inquiry & RFI | Baseline proposal with system recommendation | Within 48 hours of receiving complete drawings |
| Design Development | Coordination meeting frequency | Weekly during active design phases |
| Design Development | Drawing revision turnaround | 72 hours for standard revisions |
| Fabrication | Factory lead time after approved shop drawings | 8–12 weeks (project-dependent) |
| Fabrication | Stage inspection reports | Issued at completion of each production stage |
| Installation | Daily safety briefings | Every working day on active sites |
| Installation | Weekly progress reports | Every Friday during active installation |
| Handover | As-built documentation package | Complete within 14 days of practical completion |
| Aftercare | Defects liability period | 24-month standard warranty |
| Aftercare | Emergency response for critical defects | 24-hour response, 72-hour site attendance |
Certifications & Awards
Third-party verification of our standards
ISO Management Systems
- ISO 9001:2015 — Quality management system, certified and audited annually
- ISO 14001:2015 — Environmental management, covering factory and site operations
- ISO 45001:2018 — Occupational health and safety, applied across all project sites
Certification is not a one-time event. External audits occur annually, and internal audits quarterly. The management system is the same for a 10,000 m² tower in Shanghai and a research facility in New York.
Luban Prize Quality Discipline
Six Luban Prizes — China's highest national construction quality award — were earned across consecutive years (2008, 2009, 2015) against the entire Chinese construction industry, not a facade category. The jury evaluates engineering quality, technical innovation and social value. For an overseas owner, this is third-party proof that our envelopes perform after handover.
How We Work
The single-contract advantage
Most facade projects fail at interfaces — between design and fabrication, between factory and site, between contractor and subcontractor. Hanart eliminates those interfaces by performing design, fabrication, installation and aftercare under one contract, managed by one project team, governed by one quality system.
This is not a marketing claim. It is the structural reason our projects earn Luban Prizes and maintain performance in service. The engineer who verifies the structural model is the same engineer who reviews the shop drawings. The quality manager who audits the factory is the same manager who inspects the site. The project manager who commits to the schedule is the same manager who reports weekly progress.
On overseas projects — New York, Ulaanbaatar, Kuwait — this single-contract structure is even more critical. Time zones, language barriers and code differences multiply the cost of coordination failures. Our seven-country office network exists precisely to maintain the same single-point responsibility across borders.
