Construction cost

Salam all. I am looking to build my home in Bahria Rawalpindi phase 8. I need to know following:-

  1. Labour rate per sq. Foot without material.

  2. Bahria fees (when and how much)

  3. What is the procedure of bringing own labor in Bahria? Is there any NOC or security check?

  4. I will arrange my own material. Are there any permissions for material supplier vehicles etc?

  5. Any other thing that can cost me. Plz inform.

IN short, I want to build my own home by myself. So need to know about expenses and procedure. I heard that there are a lot of NOC'S in Bahria.

Regards

Wasim
