Abstract
During the past ten years, various systems of building components have been applied in public school projects in Iraq, with no systematic method used for selection and evaluation, but only based on the designer’s experience. This paper displays evaluation and selection techniques based on value engineering methodology to find the optimal cost for school building projects in Iraq during design stage. The most important criteria for performance, constructability and sustainability criteria, which based on the Leadership in Energy and Environment Design used in this assessment were obtained from a survey of 49 professional designers and consultants, adoption of the Super Decisions Software Program, which uses analytical hierarchy process (AHP) for determining the relative importance of the main criteria and sub-criteria, that allows the decision-makers to evaluate the suitable alternatives of design for the external wall system in Iraq’s school buildings was built.
Highlights
Optimizing building costWhen making a decision to optimize the design of the building, one must specify the various criteria to judge the optimized solution
The VE program should be established at a management level where it can effectively challenge design criteria, including established standards, and where it can have access to operational and maintenance cost
With regard to the total costs of the facility, consultant fees represent the little expenditure for all initial costs
Summary
When making a decision to optimize the design of the building, one must specify the various criteria to judge the optimized solution. The likelihood of any one solution being the best of each criterion is remote. One criterion is usually adapted and this on the basis of the use of money, becomes the objective of value maximizing with minimum cost. 2. The value system, which assigns a numerical value for "goodness" so that means "the best" can be known. 3. The means calculating the numerical value of each alternative and comparing this value with each other. The design team performs life-cycle cost analysis, and value engineering as well as model analysis
