Abstract

The total cost of a construction project involves both the cost of production and the transaction costs associated with managing the project. However, we know surprisingly little about the magnitude of transaction costs in construction projects. The purpose of this paper is to provide more empirical data as we study what proportion of the total cost in construction projects is spent on managing the project. We use the analogy of human anatomy as we investigate the size of a project’s head (managing the project) compared to the size of its body (producing deliverables). Using a dataset from 134 construction projects in Norway, we find that the project head consists of more than 18% of the total project cost on average. We also investigate how the size of the project head varies depending on a project’s complexity, size, duration and burn rate.

摘要

建设项目的总成本包括生产成本和与项目管理相关的交易成本。然而，令人惊讶的是，我们对建设项目中交易成本的大小知之甚少。本文的目的是在我们研究建设项目总成本中用于管理项目的比例时提供更多的实证数据。我们使用人体解剖学的类比来研究项目头部（管理项目）与其身体（生产可交付成果）的大小的比较。使用来自挪威 134 个建设项目的数据集，我们发现项目负责人平均占项目总成本的 18% 以上。我们还研究了项目负责人的规模如何根据项目的复杂性、规模、持续时间和燃烧率而变化。
