i Project approval thresholds are as follows: Municipal Development Council for local projects costing Php20 million and below; Provincial Development Councils- above Php20 million up to Php50 million, City Development Councils- Php50 million and below; Regional Development Council- above PhP50 million up to Php200 million; and NEDA Investment Coordination Committee- above Php200 million.
ii A Swiss challenge is a form of public procurement which requires a government agency that has received an unsolicited bid for an infrastructure project to publish the bid and invite other parties to make better offers. In some jurisdictions like the Philippines, the original proponent is given the right to match the most responsive bid received. Other countries give an advantage in price or a "bonus" to the original sponsor during the selection process instead of the right to match.
iii Project affected persons (PAPs) include any person or persons, household, firm or private or public institution who, on account of either voluntary or involuntary acquisition of assets, would lose their rights, title or interest to all or any part of the house, land (residential, agricultural, industrial, etc.) annual or perennial crops and trees, or any other fixed or movable asset acquired or possessed, in full or in part, permanently or temporarily, and who might suffer income or business loss as a consequence.
iv Alternatively, government can also provide voucher-like support to selected customers, usually low income groups, for private infrastructure services.
