Response

1.	This is the design drawing and not the shop drawings/work drawing. If the contractor wants to work, the contractor should make the shop drawing/work drawing based on the site condition and referring to the design drawing. If the design drawing is not applicable, the contractor should make the correct drawing.
2.	This item work is lump sum. The contractor should submit the drawing to cover the construction. It will not be made or designed by the owner. It depends on the site condition.
