Principle of Work Procedure 4.1 Coordination at the Site - Before starting the installation, it is necessary to prepare the site organization, delegating workers, and the required tools and utilities - Communicating with Main contractor about site office preparation and permission for transporting overweighted equipments - Find out the equipments and utilities that will be provided by the Main contractor (CSCEC 3) at the site, such as hoist, tower crane, electricity, water, and etc - Survey and understand the current progress of the main structure and the site regulations on safety, cleaning, fire prevention, and etc - Make entry identification card for all technical officers, supervisors and workers working at site - Communicating with the Main Contractor to find out the storage area at the site, and the storage size and condition for future inventory management at site - Find out the transporting area at the site for product delivery, as well as the preferred delivery time 4.2 Site Work Execution a) Site measurements and marking Since the actual 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 dimensions, measurements, and coordinates on site b) Scaffold Usage: Understand the safety requirements of the site scaffold, such as maximum load, allowed work, conditions, and etc Confirm with the 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 process will be from floors to floors, depending on the schedule of the Main Contractor, Aluminum Frame Installation With the proper finish of its surrounding structure and the area handed over, frames will be installed on to the designated spot Experienced engineers will manage and check each connection of the frame into structure, and ensure the stability of the whole frame c) Q/A of the Aluminum Frame To set up plan and prepare documents for checking the installation of frames After finishing the installation of the frame, quality control department will check the technical 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) Material: Sealants that are approved by the Architects to be applied to different areas for different functioning b) Equipment § Sealant injection gun § Plastic knife with round side Project: Vista En Feliz Page Site water testing: The site water testing for windows directly with the environment, without roof will be randomly selected according to the Owner, TVGS, Main Contractor (CSCEC 3) With the probability of selecting 10% submit The site water testing was performed immediately after the top-of-the-line waterproof silicon injection was finished Equipment for site water testing include: High pressure water pump, water pipe, pressure gauge, container system installed by the contractor aluminum glass supply The procedures and standards of site water testing are applied in accordance with AAMA 50194 According to AAMA 501-94, the test pressure is 30psi ~ 35psi, the distance from the nozzle to the test surface is 305 mm and the test time for each position is minutes 10% of the total external window of the development upon selection by Architect & Client PERCENTAGE FOR FIELD WATER

Preparation a) Preparation the tools and materials for grouting work( Sika latex, cement and sand) Project: Vista En Feliz Page 38 b) Inspection frame of location need to grouting c) Read and understand the standards required for grouting work The Construstion Steps Checking the gap follow shop drawing before cleaning Use the pump machine for cleaning the gap before Spray the water Project: Vista En Feliz Page 39 Spray the water to gap for sure cement eat the wall Put the mixture cement and Sika Latex to concrete for sure grouting eat with concrete Project: Vista En Feliz Page 40 Mix the Sika Latex and water follow the rate sika Latex + water Put the Admixture to cement and sand follow the rate cement+ sand then put in the grouting gun Project: Vista En Feliz Page 41 Use the grouting gun pump the mixture to the gap After finish grouting work, use the broom/wooden bar to checking the gap for must sure grouting full Use the broom /wooden bar to knock to aluminum frame and hear the sound from that we can clear the grouting inside full fill or not Project: Vista En Feliz Page 42 After checking grouting full, use the broom to cleaning the frame Cleaning the frame On the time finish grouting work, supervise need to inspection the frame to must sure the frame not move and take the picture for document inspection Project: Vista En Feliz Page 43 ANNEX ORGANIZATION
