site dimensions might different from the approved shop drawings, Tacheng will perform the site measurement on each item before fabricating In case of any discrepancy, we shall coordinate with the Employer/Client and the Main Contractor (CSCEC3) to come out with a reasonable solution and must be informed to Architect for approval After confirmed with the Main Contractor (CSCEC3) and architect for the actual measurements on site, these figures will form the basis of the production dimensions Equipment : Rolling Ruler - 50mm in length, Leveling ruler Preparation : All technical documents of

Main Contractor (CSCEC3) with the dates that the scaffold will be installed and taken down Negotiate with the Main Contractor (CSCEC3) to finish all the scope of work that requires scaffolding before it is taken down Installation progress a) Before material delivery to Site After being fabricated at the factory, the aluminum products will be transferred to the Q/A Project: Vista En Feliz Page department for quality control in areas such as finished dimension against the drawing, workmanship, color, damage, and etc After that, they will be wrapped with PVC tapes which will prevent surface scratch and minor damage The tape can be easily removed on site and will not remain on the surface even under high temperature to ensure that the surface of powder coating protected b) Aluminum Windows and Doors Installation: Aluminum products and components will first be transferred to the designated areas through site equipments such as tower crane, hoist, winch, and etc Installation

requirements Any error will be fixed or replaced on the timely basis (See the chapter VI & VII) 4.4 Installation of glass and sashes a) Material: Must first confirm the type of glass that is used on the approved shop drawings The thickness, color, type, and characteristics Measurement: for glass that are fixed into frames or other anchoring devices, the actual measurements from the site is required For sashes, the engineers at the fabrication plant will calculate the dimensions that can be fitted into the sash b) Technical requirement: Glass and sashes will be protected by PVC tapes and thick paper cushions at the edges/corners during transportation and storage Confirm the backer rod, gasket system, and sealant application with the approved shop drawings before proceeding Make sure the direction of the glass is installed correctly (which side faces in or out) It might be necessary to signal marking on the glass to prevent accidentally walking on to glass 4.5 Anti- absorbency a)
