Philippine property firms Ayala Land Inc and Filinvest Land Inc have submitted bids for a contract to build and operate a 4 billion peso ($87.55 million) transport terminal, a government official said. The bids for the terminal that will provide a link between the capital and southern provinces, will be opened and awarded next month, Christine Antonio, director at the Public-Private Partnership (PPP) Centre, told reporters on Friday. The other two pre-qualified bidders, Megawide Construction Corp and Datem Inc, withdrew from bidding due to concerns over the project's commercial viability. The Integrated Transport System-South Terminal Project, spread over 4.7 hectares, will connect passengers from industrial hubs in the provinces of Laguna and Batangas to other transport systems serving the capital, including the planned $3.8 billion North-South Railway project. The terminal is part of the government's PPP program to upgrade aging roads, railways, ports and airports. The government has so far awarded 10 projects worth $4.2 billion since launching the program in 2010.
