Why Partner With ANEXA
Where architectural creativity meets structural engineering rigor, factory precision, and uncompromising high-altitude safety standards.
Zero Trade Fractures
Eliminating spatial clashes between structural steel, curtain walls, MEP louvers, and waterproofing interfaces.

Engineering That Protects Your Schedule
In modern construction, the building facade accounts for 15-25% of total project expenditure and represents the primary critical path item before interior fit-outs can begin. ANEXA delivers the structural acumen, fabrication bandwidth, and disciplined site protocols required to seal building skins on schedule without commercial disputes.
01
Core Discipline
Pure Facade Specialization
Unlike general civil contractors who sub-let facade trades to fragmented labour gangs, ANEXA lives and breathes building envelopes. Every resource—from our static engineers to our lifting riggers—is dedicated entirely to glazing, cladding, and architectural metalwork.
- In-depth expertise in mullion wind-load statics (IS 875 Part 3).
- Deep knowledge of glass performance (SHGC, U-Value, VLT).
02
Turnkey Scope
Single-Window Coordination
We resolve multi-trade finger-pointing. By taking unified ownership over the structural glazing, ACP/HPL cladding, entrance canopies, and architectural louvers, our engineering desk acts as the sole, accountable coordinator for the complete outer skin.
- Single point of contact for PMCs, architects & quantity surveyors.
- Seamless flashing joints between curtain walls and cladding trays.
03
Buildability Check
Technical + Site Realism
Drawings that look gorgeous on CAD often fail on actual concrete slabs. We bridge this gap by evaluating casting tolerances, slab deflections, and installation sequences long before aluminum profiles are extruded or glass orders are locked.
- Comprehensive 3D laser scans and civil interface surveys.
- Thermal expansion allowances calculated for extreme Indian summers.
04
Fabrication Ready
Practical Detailing
Complex engineering is useless if workshop technicians cannot interpret it. Our fabrication drawings provide millimeter-explicit notch cut-lists, fastener torque charts, and gasket insertion paths that leave zero ambiguity on the factory floor.
- Automated cutting optimization minimizing aluminum scrap loss.
- Standardized bracket geometry for rapid on-site assembly.
05
Transparency
Professional Communication
We prioritize documentation discipline. From detailed Requests for Information (RFIs) and material test certificates (MTCs) to weekly site progress tracking and anchor pull-out test logs, your project management team always has complete visibility.
- Formal submittals with manufacturer warranty backings.
- Proactive reporting preventing commercial scope creep.
06
Zero Defect
Quality-Oriented Execution
Quality control happens at the source, not during final handover. We enforce dust-free structural silicone bonding, calibrated torque wrenches on every bracket bolt, and mandatory on-site water spray hose tests according to AAMA 501.2 protocols.
- Calibrated hose spray testing before scaffold dismantling.
- Methodical snag-free punch-list close-outs.
The ANEXA Execution Advantage
How our integrated engineering model outperforms fragmented site practices.
| Project Stage | Conventional Facade Vendors | ANEXA Facade Systems |
|---|---|---|
| 1. Pre-Engineering | Drawings fabricated straight off architectural elevations without verifying actual concrete slab out-of-plumb variances. | Full optical total-station survey of concrete edges to engineer custom bracket adjustments before cutting profiles. |
| 2. Siliconing & Bonding | Silicone applied manually in open, dusty site environments, leading to air pockets, poor adhesion, and premature leaks. | Controlled factory clean-room silicone bonding with strict degreasing checks, dual-component mixing ratios, and cure loggers. |
| 3. Wind Load Sizing | Generic rule-of-thumb profile sizing resulting in high deflections, whistling noises, and glass stress during severe storms. | Precise moment-of-inertia (Ixx/Iyy) calculations adhering to IS 875 Part 3 wind pressures and safety limit states. |
| 4. Handover & Leak Testing | Scaffolding dismantled without water testing. Water ingress discovered only when interior gypsum false-ceilings get ruined. | Calibrated field hose spray tests (AAMA 501.2) performed with PMC engineers present while scaffolding is still in position. |
1. Pre-Fabrication Survey
We verify every civil opening, datum line, and structural steel beam with laser tools to ensure custom aluminum framing fits on site without grinding or forceful wedging.
2. Interface Cohesion
Perimeter firestops, acoustic smoke barriers, parapet coping flashings, and external louver penetrations are coordinated under one common shop detail set.
3. Methodical Punch Closure
Every anchor fastener torque, structural gasket seat, and joint sealant profile is signed off systematically for a completely certified, leak-proof handover.
Our Unwavering Commitment
At ANEXA, we view our client partnerships as long-term engineering alliances. We treat every architectural facade package—whether a boutique corporate headquarters, a luxury residential tower, or an institutional complex—as an opportunity to elevate the buildability, aesthetic prestige, and environmental efficiency of the modern skyline.
