Curtain wall installation MethodCurtain wall installation Method

1.1. GeneralGeneral
General works for the installation of curtain wall panels should be as follows:

 Survey and set out the works from the master stations provided by the Main Contractor.
 Commencing at the lowest level a working up the building, load out and fix the unitized steel support
stanchions and beams using the existing tower crane for lifting purposes and mobile aluminium cantilevered

towers for access purposes.

 Check steelwork for line and level.
 Check torque setting of fixing bolts.
 Install floor slab trays to the projecting steel structure for others to reinforce and pour the concrete slab.
 Others to move slabs edge protection to the edge of the projection.
 Re-check steelwork for line and level.

 Install platforms at required levels, ensuring unhindered access to the work face. The existing tower crane
will be required for the installation, movement and subsequent removal of the platforms.

 The unitized glass modules will be supplied to site on stillages. Load these stillages out to the platform(s)
at the required level using the existing tower crane.

 Move the stillages on to the internal floor slab with pallet trucks.
 Install the support bracket, for the unitized glass modules, to the projecting structure and check for line
and level.

 Check torque settings of fixing bolts.
 Position a counterbalanced floor crane at the level above that is to be glazed and attach an electric which

to the cranes arm. Additionally, attach a lifting beam to the winch.

 Remove the first unitized glass module from the stillage using an ‘A’ frame and chain hoist and lower the
same on to a purpose made mobile conveyor trolley. The trolley will be designed to oversail the edge

 Move the unitized glass module to its required location and attach the lifting beam to lifting eyes that will
be attached to the module.

 Simultaneously, lift and push the unitized glass module over the edge protection and outside the line of
the building. Lower the module onto its respective bracket and lock off same.

 Continue with this operation until all unitized glass modules are installed at each elevation and at each
level. Adjust each module with the fine adjusting screws and check torque settings of fixing bolts.

 Carry out QA procedures and protect the works internally.
 Edge protection may be removed by others at this stage.
 Sequentially and when required, remove protection, clean down the works, inspect and hand over same.

For this project, the installation of Tower Unitized window Wall will be prior to the installation of Podium

Works due to construction programme requirements.

For the intention of the Owner, the Main Contractor’s Works and the Sub-Contractor’s Works will be executed

together, but Yuanda Requires that the Main Contractor’s Works and the Sub-Contractor’s Works must keep a

minimum distance of 15 floors. And before the installation commencement of Façade Works, the Main

Contractor must erect the Hard Safety Protection surrounding the building at our required floor to protect

incidental falling.

2.2. Installation of Installation of exterior decorationexterior decoration

The working procedure should be carried out from Lower to Upper of the façade. All the installation teams

should follow the perimeter of building facade during the installation works.

2.1 Embedding2.1 Embedding

According to our Yuanda’s experience in overseas construction market, we recommend to use the YUANDA

Channel as the Embeddings as below:

eroding profiles. Surface of curtain wall shall avoid contacting strong acid and alkaline solvent, if

contact them, surface of curtain wall shall be cleaned immediately to avoid impairing the cladding.

When welding, cutting and blasting sand, sparkle caused by them shall be avoid spattering onto the

cladding. Only may elastic not rigid substance contact finish.

b) Product guardian shall be appointed to protect installed product during installation so as to make any
damage to it. In construction, builder of main structure and main contractor shall be invited to cooperate

with us.

c) After product installation on every floor, erector of main structure, supervisor and main contractor shall
engage in preliminary test and make a signature. Preliminary test is to protect product quality after

installation and we will invite erector of main structure and general contractor to protect product by

organizing fixed person.

d) If interior needs decorating, erector of main structure and general contractor shall send a letter to our
project department, they accompanying with interior decorative unit shall be invited to check our

products together and take necessary measures to protect our finished products after four side’s

The stuff shall be transported to site by truck. Unload by mobile crane or forklift provide by the main


4.2 Survey4.2 Survey

When the civil engineering installation is completed, the team carries on the localization survey first to

measure out the error of civil engineering structure and make preparation of following installation. After that

benchmark line is confirmed, the arrangement benchmarks of partial curtain walls are measured in order to

confirm the benchmark of different positions in three directions.

4.3 Fix aluminum composite panel4.3 Fix aluminum composite panel

Aluminium panel will be prefabricated in workshop. Every panel has a part no. According to shop drawings,

hung aluminium panel into aluminium extrusion which has been fixed on steel frames in advance. Then adjust

the panel to appropriate position. Finished aluminium panels shall be flat, and the gap between panels should

be consistent.

4.4 Clean4.4 Clean

Upon completion of our works in a given area (i.e. one floor or part thereof), we will carry out necessary

cleaning prior to the inspection. This activity will be closely supervised. Likewise we will carry out our own

inspections and do the remedial work deemed necessary if any. Protective films will not be removed at this

stage. This is to further protect the panels from any possible damage. Unless, however, instructed otherwise by

the Employer, the said films will be removed.

5.5. Installation of Aluminum Cladding for podium canopyInstallation of Aluminum Cladding for podium canopy

Its installation method and procedure is the similar to installation of Aluminum Cladding for Arches, and

the only difference is that adopting method of scaffold in podium.
