Abstract

Project cost efficiency can be done in things such as value engineering. The value engineering process can be carried out at the conceptual, planning and implementation stages of the project. Design changes also have an impact that affects the performance of construction implementation. Currently wood material is still widely used for finishing work, such as the roof of a pergola, room dividing walls, or just as a glass clamp. This research uses quantitative descriptive analysis, which begins by calculating the volume of work, determining the coefficient of wood material, compiling a unit price analysis, calculating the budget for existing designs and changing designs, making comparisons between the two designs. The unit price of the existing design for a room dividing work with 30x50 mm wood including a frame with 50x70 mm wood is IDR 2,597,451 per m2. For roof work, timber lattice pergola with 40x60 mm wood is Rp. 848,726 per m2, and grilling work for lattice with 40x60 mm wood is Rp. 777,070 per m2. The total budget for the existing design is Rp. 335,303,754.84. The total cost budget with the design change is IDR 289,335,447.58. The cost efficiency between the existing design and design changes is IDR 45,968,307 or 15.90%

Abstract

Construction projects are activities carried out with limited time and costs. In its implementation, the project requires resources, namely materials, wages, tools and decisions on the use of subcontractors. Project implementation always begins with implementation planning. This activity consists of planning work methods, calculating project resource requirements, and determining the schedule for procuring these resources. Every project implementation always has risks in it. This risk can originate from human resources, implementation methods, and work environment conditions. Due to the limited time for implementing construction projects, it is not uncommon for planning project resource requirements to experience calculation errors. This error could be a lack of budget allocated to one of the project resource components. This research was carried out with the aim of obtaining the proportion of each resource, namely materials, wages and tools, which can later be used as a reference in preparing project plans in a short time. This research was conducted on a building construction project that functions as a hotel and villa. The projects reviewed are 2 hotels, 1 villa and 1 resort. The results of this research show that the average proportion of project resource use to the total value is (1) Materials 64.45%, (2) Wages 24.75%, (3) Tools 7.64%, and (4) use of subcontractors 3 .17%. The proportion of use of material resources, equipment, wages and subcontractors is greatly influenced by the type of building construction, material specifications and work contracts.
