The Zhongyin Plaza 3# Building project highlights the installation of a high-performance glass curtain wall system, covering the complete construction process from survey control and framing installation to hidden-frame glazing, weather sealing, fire stopping, and project handover. Through precise execution and quality control, the project demonstrates how accurate installation practices contribute to facade performance, safety, and long-term reliability.
Project case study | Survey control, framing accuracy, hidden-frame glazing and weather sealing
The facade design was reviewed and coordinated through architectural elevation drawings before installation. These drawings defined the building appearance, curtain wall coverage, panel arrangement, and key dimensional references for the subsequent fabrication and installation process.

Glass thermal performance and aluminum strength of REACH BUILDING project
The following schedule translates the current material selections into design-review controls. Glass values are preliminary reference targets because the exact LOW-E coating, cavity gas, spacer and edge conditions are not yet specified. Aluminum profile series describe section geometry, so the final strength values must be confirmed by the alloy/temper certificate and structural calculation.
Confirm coating position, cavity fill, spacer type, edge conditions, and final energy calculations before procurement.
Thermal note: U-value is the primary heat-transfer control. The LOW-E coating must be located inside the insulating-glass cavity, and the final product data should be submitted with the glass make-up, coating designation and calculation conditions
Select the value based on actual wall thickness and temper. Verify bending, deflection, local buckling, brackets, fasteners, and splice joints through project calculations.
The 70 series identifies the section family rather than the strength grade. Final verification should use certified alloy/temper data and actual section properties.
Aluminum note: the reference ranges above reflect thickness-dependent minimum values for extruded 6063 profiles. They are not a substitute for the supplier's material certificate, profile section properties or the curtain wall structural calculation. Reference data: Hydro EN AW 6063 extruded-products technical data under EN 755-2:2016.
How to install Implicit curtain wall
The building uses a mix of glass curtain wall, aluminum panel curtain wall, grille elements, titanium-zinc panels and a glazed roof structure. For the glass facade, the installation logic had to absorb real structural conditions without compromising line, level or weather performance.
Core project principle: resolve the building in measured increments, verify every frame zone before glazing, and keep the final seal continuous from the facade to the primary structure.
Five controlled moves to improve your accuracy
Each installation stage was carefully coordinated to control positioning accuracy, structural performance, and sealing quality throughout the facade construction process.
No.
Installation Stage
Key Actions
01
Survey and Control
Establish the façade coordinate system based on the main building axis to ensure accurate positioning and installation control.
02
Mullion Installation
Adjust embedded components and install curtain wall mullions according to the verified structural positions.
03
Transom Installation
Install horizontal transoms according to the design drawings and verify alignment and level accuracy.
04
Hidden-frame Glazing
Install glass panels with proper setting blocks and complete hidden-frame glazing according to the installation requirements.
05
Weather Sealing and Fire Protection
Apply perimeter sealants and mineral fire-stop insulation, followed by cleaning, protection, and final handover preparation.
When we are conducting construction above the third floor, to ensure the installation accuracy, we will recheck the installation of the curtain wall for each floor. Especially after half of the floor has been constructed, we need to test the wind force approximately every 4 hours. When the wind force exceeds level 4, it will have a significant impact on the construction accuracy. We will immediately suspend the installation when this happens. For each floor, we will record the product batch number and conduct sample inspection of the sealant to prevent the unstable quality of the sealant from affecting the overall performance of the curtain wall in the later stage.
How to ensure the accuracy during the installation of glass curtain walls
The source method statement treats setting-out as a closed inspection loop: establish the reference, build the control grid, verify deviations, correct them and archive the result before the next layer begins.
Control item
Source-based inspection standard
Datum and references
Use the primary structure's ±0.00 datum, the supplied 1 m line and axis lines as the setting-out basis. Establish the benchmark and horizontal control network before locating the curtain wall grid.
Instrument readiness
Prepare a theodolite, level, plumb bob, tensioner, water level and welding equipment. Use calibrated measuring instruments and verify the building condition against the design and construction drawings before measurement.
Inspection sequence
Set the key floor horizontal line, establish auxiliary level lines, mark mullion locating points, reinforce the points, pull the horizontal line, check and adjust error, complete horizontal zoning, recheck the zones, hang and fix the vertical line, then inspect corners and every facade transition.
Deviation closure
Report the control line for inspection, measure embedded plate deviation, report the result, correct the structural deviation, remeasure and file the final measurement record. Errors are decomposed promptly rather than accumulated between floors.
Curved facade
For the curved market elevations, use X/Y point coordinates to define the outer skin point of each mullion. Set the horizontal grid by elevation, verify the chord/radius relationship, mark each +500 mm control line and transfer levels floor by floor from the ground control point.
Working conditions
Carry out high-rise measurement only when wind force is no greater than level 4. Repeat the survey at a fixed time each day to reduce temperature-related movement and keep the facade grid consistent.
Related fabrication checks
Mullion cutting: ±1.0 mm; transom cutting: ±0.5 mm; hole position: ±0.5 mm; hole spacing: ±0.5 mm; cumulative tolerance: no greater than ±1.0 mm. The source also records the end-angle tolerance as 15 degrees.
The material structure of the curtain wall
To ensure the structural performance of the curtain wall, the entire curtain wall is composed of multiple material structures. The fire resistance performance, structural performance, aluminum material strength, and glass performance are combined to form a complete and high-performance curtain wall structure.

Quality standards for curtain wall installation of REACH BUILDING
The case is not only about appearance. It is about closing the small technical decisions that protect alignment, safety, water resistance and durability.
Quality Checkpoint
What Is Closed Before Handover
Measured Before Fabricated
Review drawings, remeasure the primary structure, and adjust any curtain wall deviation only with the required design approval.
Frame Tolerance Under Control
Documented cutting tolerances include ±1.0 mm for mullions, ±0.5 mm for transoms, and ±0.5 mm for hole position and spacing.
Glass Protected at Every Edge
Do not allow direct glass-to-metal contact. Use the specified elastic blocks, gaskets, and edge clearances before pressure components are closed.
Sealant Is a System
Clean and dry the joint, prevent three-sided adhesion, use backing material, tool the bead smooth, and remove excess sealant immediately.
Fire and Rain Stay Continuous
Fill the facade-to-structure gap with fire-rated insulation and close the interior and exterior faces with a continuous watertight seal.
Handover Includes the Record
Complete final cleaning from top to bottom and deliver both the finished facade and supporting quality documentation.
Technical basis referenced in the source method statement includes GB/T 21086, JGJ 102, GB 50300, GB 50210 and related glass, fire and structural installation standards. Always confirm the current project specification and applicable edition before construction
Conclusion
The Zhongyin Plaza 3# Building project highlights how accurate surveying, reliable curtain wall systems, and disciplined installation processes contribute to a high-performance glass facade. Through coordinated control of framing, hidden-frame glazing, sealing, and quality inspection, the project achieved both architectural appearance and long-term facade performance.
