Bidding activities shall follow the principles of openness, fairness, impartiality and good faith. Bidding documents shall not set unreasonable conditions to restrict or exclude potential bidders. The bid evaluation committee shall have an odd number of 5 or more members, with no fewer than 2/3 being technical and economic experts.
