Estimating cost in construction is important to the city's design and planning management hence, estimate must not be overpriced which may cause corruption or underpricing that leads unreliable low-quality road projects. The total estimated only valid same year it was proposed because of inflation rate costs change. researchers applied Multiple Linear Regression technique predicting for analysi...

This paper presents a study of cost escalation in unit price road construction contracts. The aim is to investigate why the final contracts differs from agreed contract following tendering, both identify causes observed discrepancies and suggest measures that could improve planning delivery future projects.

Abstract The main problem of road construction on saturated soft soils is due to their low bearing capacity and large settlement. One the solutions such problems install piled box culverts-geofoam. In this study, pile culvert-geofoam was modelled as raft foundation. This experimental study conducted by making a prototype file foundation gradually loaded with maximum vertical load 20 kN. Differe...
