2 Long Term (6-months) : 1. Have a qualified structural engineer prepare load plans including the information required in Section 8.20 of the Alliance Standard. 2. Provide signage or the appropriate markings at all areas used for storage to indicate the acceptable loading limits detailed in the Load Plan. 3. It is recommended to perform another geotechnical report under guidance from a qualified structural engineer at close vicinity of the structure for clarity with previous assessment and make the report available for review. The recommendations for Fire & Electrical Safety corrective action are: (A): Recommendations for Fire Safety corrective actions: Immediate (the factory should not continue to be occupied until these non-conformities have been rectified): Short Term (Actions that must be incorporated into a Fire Safety Management Plan immediately (1 ~ 2 weeks) and should be a regular activity N/A Factory safety Manager/Director needs to arrange fire safety training for the workers of the factory from proper authority time to time. Ensure adequate numbers of fire drills under the Fire Safety Plan. All the firefighting equipment need to be tested with proper documents. Propagation of fire, smoke, gas or fume through the opening of fire resistive floors and walls need to be restricted by sealing such opening with an approved material which needs to have a minimum 2 hours fire resistance rating of the walls. Combustibles are to be managed with good housekeeping.

3 not less 20 mm; (c) The source of illumination, contrast, intensity and luminance needs to be at least 50 lux, 0.5, 5.0 foot-candles and 0.2 cd/m2 respectively. Mid Term period of 6 weeks) Factory needs to have as built drawing with proper dimensions showing all the means of escape. All the exit doors of staircase enclosure need to be replaced by side swinging fire rated doors with self-closing mechanisms so that the staircase remains free from smoke and it needs to be opened in the direction of travel as well as the lockable doors can be opened easily in the direction of evacuation without the use of a key. Provide handrail on both sides of stairway-3. (a) Illuminated emergency light needs to be covered in floor, exits and aisles. (b) The intensity of illumination by means of escape lighting needs to be equal or more than 10 lux. The aisles need to be illuminated with escape lighting to a level of not less than 2.5 lux at floor level. Emergency back-up power needs to be connected for critical fire safety system and not less than 30 minutes in case of failure of power supply. Long Term period of 6 months) Factory needs to have a proper pre-plan for fire department. Factory needs to maintain minimum width of exit 0.9 m and height 2 m. Final exit route-1 need to be protected (2 hour rated construction with 1.5 hours rated door) at each floor level entrance including ground floor, also need to protect from transformer room by 4 hours rated construction with 2 hours rated doors/opening at ground floor and have the protected route till to reach safe refuse area. Final exit route-2 need to be protected (2 hour rated construction with 1.5 hours rated door) at each floor level entrance including ground floor, also need to protect from generator room by 4 hours rated construction with 2 hours rated doors/opening at ground floor and have the protected route till to reach safe refuse area. Final exit route-3 need to be protected (2 hour rated construction with 1.5 hours rated door) at each floor level entrance including ground floor, also need to protect from storage area room by 2 hours rated construction with smoke proof lobby at ground floor and have the protected route till to reach safe refuse area.

4 Child care room is needed to be separated from other occupancies with 3 hours fire rated construction with 3 hours fire rated door. Storage area need to be protected with 2 hours rated construction & 1.5 hours rated opening or doors with other occupancy. Boiler and generator room needs to be fire separated with 4 hours fire rated enclosure and 2 hours rated opening having direct access from outside. All the exits connecting to the staircase need to be protected with fire and smoke resistant enclosures and opening (2 hours rated enclosure and 1.5 hour rated door) and provide a protected route from all though the stairway to the final exits. Factory needs to provide 3 hours rated construction between office and finishing section. For dining & prayer room fire separation follow guideline Article No & Table 2.1 of NTPA Factory need to have 2 hours fire separated & smoke proof lobby in the entire staircase. Factory need to protect the basement by 2 hours fire separated and smoke proof lobby Factory need to install centralized and automatic fire detection & alarm system on all occupied floors, including other tenanted floors of the building as per NTPA Guideline. Factory needs to install manually operated electrical fire alarm system with single or multiple call boxes as well as automatic fire alarm system for centralized automatic fire detection and alarm system.

5 (B): Recommendations for Electrical Safety corrective actions: Immediate (the factory should not continue to be occupied until these non-conformities have been rectified): Short Term (Actions that must be incorporated into a Fire Safety Management Plan immediately (a week) and should be a regular activity) Mid Term period of 6 weeks) Remove all unused cables from distribution boards and make sure all necessary cables are properly terminated at its point of termination using appropriate size and type of lug. Ensure all distribution boards (including panel door) are earthed properly. Install MCCB in proper way to ensure safe installation. Ensure overcurrent protection device (circuit breaker/fuse) for each circuit and branch circuit. Clean interior components from dust and debris and seal all openings within the enclosure to prevent dust and debris from entering. Provide provision for inspection of all earthing system and ensure inspection is being completed and documented. Fill the transformer breather oil cup with fresh Oil. Provide two separate and distinct connections of earthing for each generator. Provide dedicated & adequate size of earthing with proper identification for each circuit from the earth busbar of distribution boards and ensure continuous earth path is back to main building intake. Rewire to ensure each incoming supply to an MCB has a dedicated supply from bus bar. Avoid the use of multiple cables on outgoing side of MCB s and bus bars. Ensure all electrical cables are sized according to capacity of circuit breakers. Ensure cable joints are made in respect of conductivity, insulation and mechanical strength. Connect all metal in the building to the building earthing system. Develop an electrical layout diagram and an as-built single line diagram detailing key components and capacity of the electrical system. Galaxy Stitch Ltd. Last update on Page 5

6 Long Term period of 6 months) Establish a periodical Insulation and earth Resistance Measurement Program and record the related testing data. Inspect electrical switchgear and panel boards on an annual basis. Ensure the substation room has adequate fire separation from the production area. Ensure the generator room has adequate fire separation from the production area. Ensure distribution boards have no opening and all live internal components are concealed properly. Provide dedicated & adequate size of neutral with proper identification for each circuit. Ensure each distribution board is provided with a circuit list and means of identification is provided as per list. Provide adequate covers on cable channels. Provide proper cable terminator/connector for stranded conductors at its point of termination. Install separate distribution boards for lighting and power circuits. Install lightning protection system on the building. Galaxy Stitch Ltd. Last update on Page 6
