Course Description

This course is designed to prepare students to handle the practical tasks the engineer is exposed to in the real life. The topics discussed in readings and course lectures are selected to give the student a comprehensive understanding of the process of generating, bidding, and performing construction contracts,components of direct and indirect construction costs, work breakdown, contingency and risk.. This course teaches the methodology, procedures and organizational techniques involved in preparing a competitive bid. Detailed estimates for each major construction discipline are prepared, based upon real construction project documents. Ethical considerations in budgeting and estimating are discussed. The final project is the preparation of a formal competitive bid on a project. A study of methods and operations in managing projects from both the perspective of the constructor and designer. Topics include elements of the construction process, project delivery types and types of construction contracts.

Course Objectives

The course is part of the core course requirements for the Bachelor of Science in Civil Engineering. The course will provide the students with a thorough understanding of the issues related to the application of cost estimate, specification and construction contracts in the construction industry. It is intended to provide an in depth discussion of some of the important contracts and bidding  issues faced by various agencies involved in the construction industry.

The principal objectives of the course are to:

  1. Provide an overview of the construction contracts and bidding process and introduce various construction contracts
  2. Develop an understanding bidding process
  3. Highlight issues related to relationship between the parties in the construction process
  4. Explain the design and construction process and the roles of the different
  5.  Outline the contents and relationship between the documents which make up the Construction Documents.
  6. Describe the different types of contracts, the number of contracts, the method of contractor selection and the basis for contractor payment
  7. Explain the bidding process, including the documents included in the bidding requirements
  8. Describe the Conditions of the Contract, their purpose, content, and relationship to other parts of the Project Manual.
  9. Explain the distinct roles of Drawings and Specifications
  10.  Describe the various methods of specifying
  11. Describe the types and purpose of construction bonds and insurance
