Value engineering for drainage and stream way in roads and highways construction

Abstract

Value Engineering (VE) is a total management approach to improve the quality of construction projects. It increases the efficiency and performance of the projects to gain the best integrated benefits. The VE focuses on function analysis of the researched subjects and strives to achieve the required function reliably at the lowest Life Cycle Cost (LCC). It seeks optimizing and improving decision making to realize the optimal expenditure of owner funds while meeting required function. The VE teamwork involving construction, design and maintenance staff reviewed the construction project features and acquire for ways to improve quality, control costs and time. This study focused on investigating the role of VE for existing main road construction projects. It uses the Drainage Engineering Systems (DES) and Surface Stream Way Drain (SSWD) after rainfall in the environmental health view point related to VE. It predicates to decrease the air pollution and increasing the health of environment. The main goal of this study is to design an enhanced VE framework with main factors of drainage management in the main road. In this study, VE questionnaire was sought to determine the overall thoughts, vistas, notion, comprehending and understanding in addition to the connection to LCC price for drainage and runoff of main roads, highways and streets. The quantitative data were analyzed using one-way ANOVA technique and Factor Analysis of smart PLS. The expert respondent provides scientific data, on the initial questionnaire with thirty perfect answers. The qualitative data was used to support the quantitative results to provide a mathematical framework between the twelve important main factors of VE, DES and SSWD related to the factors of Construction Management (CM), Materials (M), Environment (E), Human Resource (HR), Quality (Q), Aesthetic (A), Cost (C), Time (T), Waste Materials (WM), Safety and Safety Driving (S and SD) and Recycling (R). The findings revealed that the VE by working team can increase performance and increase runoff collection of main roads, highways and streets. The framework also decrease within the lowest possible cost, time, waste materials and increase possible quality, aesthetic, safety driving and most possibly can effect construction management, materials, recycling, human resource and environment. The new framework of VE accepts all twelve main factors with only aesthetics factor being rejected. The new VE framework is capable to save cost, time and increase quality of road drainage system.
