Dear Khun Preecha,
Thank you very much for the advice.
So we will not attach the sample photo for fence quotation and will use only your design details. I will adopt your details as HHT standard for future HHT projects.
For covered walkway (about 145m long), we will compare the cost of the materials. If not much difference then we will provide all cement boards.
For reuse of materials I take your point. HHT has no storage yet for materials between the two stages of Building A. Hence we may let the materials all belong to subcontractors and let them manage the materials, which will be decided later.
Finally, the simplified construction planning which I prepared is for presentation to TNC for their easy understanding and explanation to the Chefman and BSTG Owner, it cannot be used by the subcontractors. Hence, we will include your original version with dimensions and details for giving to the subcontractors. Could you please help me to update the G/F fencing plan as we have now combined the WWT & Kiosk work with the Building A splash working area now. Thanks.
