How much do materials, labor and indirect expenses account for in the whole project?

In construction projects, materials account for about 60% of the project cost, labor wages account for about 30% of the project cost, and overhead costs account for about 10% of the project cost.

Due to the difference in material cost, labor cost and charging rate, it depends on whether the local engineering materials, labor wages and relationship fees have changed before and after signing the contract.

The project cost consists of labor cost, material and equipment cost, construction machinery cost and overhead cost, and there is a reasonable proportion among them.

Extended data construction project refers to an engineering entity formed through the construction of various buildings and their ancillary facilities and the installation of supporting lines, pipelines and equipment. Among them, "building" refers to projects with roofs, beams and columns, walls, foundations and internal spaces to meet the needs of people's production, life, study and public activities.

The Civil Engineering Teaching Steering Committee consists of nine professional steering committees (hereinafter referred to as professional steering committees), namely, civil engineering, building environment and energy application engineering, water supply and drainage science and engineering, building electricity and intelligence, architecture, urban and rural planning, landscape architecture, engineering management and engineering cost, real estate development and operation, and property management, which respectively correspond to civil engineering, architecture, management science and engineering (part) and business administration (part) in the undergraduate professional catalogue of colleges and universities.
