4 Vuong, RPLLC -Page 18/131: Where is show screen will be stored at the site Those are in the bath room Please see the item no 7.3

5 Vuong, RPLLC -Page 30&31/131: Provide size of gecko & screw

Please see the section detail in annex

There are two type of screws, longer one is 40mm (ø 4) to fix onto the wooden frame and shorter one is 10mm (ø 4) to fix onto the tile surface as its details

In terms of the plastic gecko in general, shall be matched for each screw length and diameter

6 Vuong, RPLLC How to control quality of mirror & glass? We will get randomly samples for testing or not?

The test was conducted for tempered glass sheet on middle of march in this year as attached certification

So we would think of that can be proved the quality of

it

7 Tan, ICIC Page 23/131: It is better if using screws to fix SS U bar on wall and floor Fixing u-bar, will be fixed by silicon with grasping slot within flexible silicon grip because there has a

waterproofing layer which have to avoid any damage

Page 27/131:

 How to prevent wall tile from breaking when installing the hinges?

 How to connect glass door to hinge?

 Cutting by grinder to make the glass sheet inserting slot

 It shall be used by the grasp device which has fastening bolt with rubber sheet in it

9 Tan, ICIC aluminium u-bar? be used to avoid any harm to the waterproofing layer

and tile also

Page 32/131: Based on approved shop drawing, the interval distance of silicone dot is 150mm not 350mm 150mm distance is accurate It has corrected as the drawing

11 Tan, ICIC Page 33/131: Will silicone be applied around mirror to cover the gap between mirror and aluminium V bar? The silicon for bonding agent shall not be covered on the mirror and v-bar frame because it will be possibly

5.3 Site Work Execution

1) Site measurements and marking

Since the actual site dimensions might differ from the approved shop drawings, Subcontractor will perform the site measurement on each item before fabricating

In case of any discrepancy, we shall coordinate with the Employer and the Main Contractor to come out with a reasonable solution After confirming with the

Main Contractor of the actual measurements on site, these figures will form the basis of the production dimensions

Equipment

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)

7 Method Statement

7.1 Logistic Method

a, After the fabrication finish in the factory, the glass will delivery to the site by the lorry

b, When the Lorry come to the site, Workers down load all Glass

c, Product inspection by M/C before move to the Storage

d, Storage

 Delivery of materials should be carefully planned according to the installation schedule so that only the required quantities of materials are stored on site, where the possibility of damages is higher

Glazing work Storage

 Just-in-time (JIT) inventory management system is effective in minimizing unnecessary handling, storage and damages to the materials

 Require a stock area of approximately 30 to 40 m2

 Proper site storage is important in preventing damages to glass

A suitable storage location should be:

 sheltered from weathering and fallen objects; and

 located for ease of material handling and distribution

 Site unloading areas shall be provided for incoming material It should be close to stock point area for ease of unloading and distribution

 All glass are to be checked dimension & quantity prior to site storage against delivery order/invoice

 In addition, the various components should be arranged according to the installation sequence to facilitate ease of retrieval, i.e to minimize searching and unnecessary shifting of materials which may lead to damages

7.2 Lifting Method

 All vehicle movements and deliveries will be subjected to SSY

 The storage of materials on site ground level will be kept to an absolute minimum and therfore delivery scheduling will be carried out to ensure supply is on a “Just

in time” basis

Glass

1) After the opening finished,

Workers will transport frame from

the Storage to the Hoist

 If the Glass frame are small and

short, the worker will bring by

hand

 If the Glass frame are heavy or

big, we will use small car or

forklift

7.3 Material Distribution Plan

a Typical floor material distribution

b Plan for transport the glass on work floor

All the worker must wear the gloves before bringing

the Glass frame

When the Glass frame is delivery to the site, it will

gather at the storage or in the safety zone

The workers will use the Small Car to transport the

Glass frame from the storage to the Hoist

The Small Car and Glass frame will be in put in the

Hoist and will be transport to the floor

When Glass fame comes to the floor, it will be put in

the Platform safety
