Abstract

Recent research has demonstrated the feasibility of identifying, within any category of project, a small number of cost significant work packages whose value represent a consistently high proportion of the total bill value. Using the allied principle of quantity significance, it proved possible to build simple models, which could predict both the cost and the duration of a project. In the course of that work, a surprisingly linear relationship between value and quantity was noted. This paper reports the background to and consequences of that finding. Quantity-significant work packages are formed by aggregating those items within a trade for which a linear regression of value against quantity yields a correlation coefficient greater than 0.99 and an intercept insignificantly different from zero. The price of packages formed in this way can be determined simply by applying to all the items within the package the rate associated with the largest quantity, the so-called “characteristic item”. Application of the concepts of quantity-significance and characteristic items is expected to lead to simpler estimating and more effective control procedures, because there is no longer any need to allocate cost and resources to each individual item contributing to a work package. Keywords: Cost estimate, cost control, significance, cost modeling

الملخص

أثبتت الأبحاث الحديثة إمكانية تحديد عدد من الرزم الأكثر أهمية في أي مشروع والتي تمثل قيمتها نسبة ثابتة من التكلفة الكلية للمشروع. أن استخدام نظرية الكميات المميزة أثبت إمكانية عمل نماذج بسيطة تمكن من تقدير الكلفة والفترة الزمنية للمشروع، وقد لوحظ أن هناك علاقة خطية مدهشة بين التكلفة والكمية. يقدم هذا البحث خلفية أثر هذه النتائج. لقد جمعت الرزم الأكثر تميزاً من عدة مشاريع ومعامل الارتباط ما بين الكمية والتكلفة كان بنسبة تزيد على 99%، كما يمكن تحديد أسعار الرزم بضرب سعر الوحدة الأكثر كمية بالكميات الكلية للرزم. إن استخدام هذه الطريقة يمكن من حساب الكلفة ويسهل مراقبة المشروع دون الحاجة لتوزيع الموارد على كل بند من بنود الاتفاقية.
