This document provides details of the design workshop for Package 5A, a 9.6 km section of a highway project between Raub and Bentong in Pahang, Malaysia. Key information includes: - The section has 2 interchanges and 2 signalized junctions. There are 5 bridges, 2 vehicular box culverts, and 1 underpass. - Geometrical design standards include a design speed of 50-90 kmph and maximum gradient of 5%. - Earthworks include over 2.9 million cubic meters of cut material and over 2.7 million cubic meters of fill. - 5 bridges ranging from 25-40 meters in span are designed for heavy vehicle loading. -
