Abstract

This publication represents the second report of the CII Model Plant Project. The first report, Publication 2-1, was published in 1986 and is an introduction to the project. This update presents comparative information on Baselines 1 and 2 of the project.

The need for an industry-wide construction productivity measurement baseline has been recognized for a number of years. Construction productivity data for nationwide use are either not available or considered unreliable. The Business Roundtable Construction Industry Cost Effectiveness (CICE) Project Report A-1, “Measuring Productivity in Construction,” included a recommendation to measure site level productivity in selected private construction segments. The report suggested a logical segment scheme based on construction volume.

The CII Model Plant is a typical facility physical baseline against which to measure construction productivity. A typical petrochemical facility was chosen as the initial physical baseline facility. The primary goal of the Model Plant project was to develop a basic petrochemical plant, simple and generic in nature, such that the construction industry could have a physical base against which to measure productivity. Data from collection of direct labor estimates for a typical petrochemical processing facility were chosen as the foundation of the baseline, hence the name “Model Plant.”

CII members (contractors and owners), based upon their own actual experience, have estimated the amount of construction labor that would be required to build selected parts of the Model Plant utilizing a code of accounts which has been established for the various scopes of work at both a detailed and summary level. Two estimates have been prepared, the first in 1985 and the second in 1987. The initial estimates were used to develop Baseline 1 and the second to develop Baseline 2. This report establishes the format for analysis in determining trends from the data generated.

Summary information on Baselines 1 and 2 and a comparative analysis are presented in this publication. For those who may wish to analyze the data in detail, CII Source Documents are available. In addition, the data for Baselines 1 and 2 are available in mini-disk form for those with personal computer capabilities.
