Abstract: Research on uncertainty in construction has emphasized the importance of incorporating uncertainty factors in project‐cost and time forecasts. However, little attention has been paid to identification and quantification ...

Abstract: It is widely accepted that environmental uncertainty strongly affects decision makers' performance and that the construction environment is very uncertain. Despite awareness of the consequences of uncertainty on a project, ...

Abstract: We investigate the effect of exit pressure history on the flow characteristics of underexpanded transient jets. Using both experiments and numerical simulations, we study the dynamics of shock-cell and vortex structures ...

Abstract: The purpose of this paper is to study the dynamic behavior of a pedestrian bridge in Alicante, Spain, which showed vertical and horizontal vibration problems. Moreover, the deck’s structural steel showed severe corrosion ...

Abstract: This paper presents results of full-scale lateral load tests of one single pile and three pile groups in Hong Kong. The test piles, which are embedded in superficial deposits and decomposed rocks, are 1.5 m in diameter and ...

Abstract: The unsteady wake characteristics of a butterfly-shaped wing undergoing flapping and feathering motions are studied. A 4-bar quick return mechanism is used to generate the flapping motion. To achieve considerable feathering ...

Abstract: Construction planning systems have been the subject of research, development, and implementation for the last several decades. Most studies have focused on planning tools and techniques, and not on the planning process ...

Abstract: Following a previous paper, which described the planning process in the construction company at the early stages of prebid and preconstruction, this paper presents the results of a research program that studied the planning ...
