DACUDAO-LAUREL-BUHANGIN FLY-OVER, Davao City, Mindanao. The Dacudao Laurel Buhangin Davao’s flyover, the first one in the whole Island of Mindanao, a Design and Build Contract, was awarded to Foundation Specialists, Inc. by the Department of Public Works & Highways. The site conditions of the Flyover were quite challenging, because the site of ramps and embankment is underlain by a soft clay formation. In order to provide a firm support for the embankment and the ramps, there were three common solutions, all quite expensive, provide extensive number of piles for a settlement free base to the embankments, put the whole flyover on piles , pile caps, columns coping, girders and slabs, or remove the clay formation and provide a compacted backfill. Foundation Specialists, Inc. provided a fort and cheaper alternative method, and consolidated the underlying clay formation using its patented FS Soil Cement Columns System, a deep-mixed jet grout providing high strength soil-cement columns. The Choice of the FS Soil Cement Columns System, made FS Bid very competitive, and in fact FS was awarded the Design and Build Contract for the Davao flyover. The Flyover was inaugurated by President Ramos in 1994. Davao City has used the aerial picture of Dacudao-Laurel-Buhangin  Road Interchange (in figure) as the City Icon for several Local events. During the same year 1994, Foundation Specialists, Inc. in Mindanao was the General Contractor for the National Steel Corporation in Iligan City, and in Zamboanga Del Norte  for DPWH  4th ADB completing the 94 Km  Dapitan-Manukan Highway  and the 1Km  Polo Bridge
