Also called as value analysis and one of the most important steps in the value management process. Value engineering is a methodical process to transform the project into its most functionality with spending the lowest cost. As an example, this can be achieved by substitute materials or alternative building methods (but without forfeiting functionality of the project. A standard methodology is followed in the value engineering process. There are six phases or six steps in this process.
The methodology of value engineering
Gathering of information
The building team has carefully gathered the information about the design such as critical elements, each elemental purpose, cost of the element, the elemental value after build etc. In this phase, the value engineering team can identify the secondary function of the element as well as basic function of the element.
In this phase, the team has identified the alternative designs to the critical elements. These designs will not be affected with the anticipated purpose and the quality of the element, these alternative design can be a partial adjustment to the initial design.
Comparing each alternative design is done in this evaluation phase. All the alternative design ideas are carefully evaluated to ensure there will not any various from the anticipated functions and purposes of the functions by the value engineering team. After justifications best solutions are selected to implement.
In the development phase, the value engineering team is developing the selected alternatives to achieve the anticipated purposes as well as the value of the element. Some small variations will be added to ensure alternative designs are fully capable to achieve its function similar to the initial design at a reduced maintenance cost and initial cost.
At this phase design team will meet the value engineering team and they will report their suggestions and recommendations to the design team. The worthiness of the recommended ideas has to be communicated to the design team very careful manner to persuade the design team.
In this stage, the design team is doing auditing to the implemented recommended value engineering options. After that progress or the problems will be reported to the concerned parties by the value engineering team.
Project is an 11 stories apartment housing building worth 52 million which followed the design & building procurement method. The owner of the building more concerned about the durability of the building. Therefore design team has proposed cast place durable concrete with extra reinforcement. Also to assure durability design team has decided to change the window thickness. Most of the cabinets and the finishes also changed to guarantee the durability of each element. Energy-efficient light fittings and the appliances like High-Efficiency Aaon, High-Efficiency VRF system, High-efficiency garage lighting, 1.5 GPM showerheads and faucets units.
They also choose to use ENERGY STAR Qualified Refrigerator, Clothes Washer, Qualified Dish Washer (25% Improvement) as appliances.
Apart from that Fixed building shading, self-shading are installed to guarantee low energy consumption of the building.
