Construction Management: Principles & Practices
()
About this ebook
Most publications deal with just one or more aspects of construction management, such as scheduling or cost management, without providing an overall understanding of construction management in the construction industry.
This book is intended to fill this gap by providing an overview of all types of activities and subject matters required in managing a construction project. These items include but not limited to the various contract types, bidding process, change management, as well as contract negotiations. The various materials & testing and required permits are also discussed
The book follows a sequential arrangement of its chapters similar to the sequence of activities on a construction project. Author is an experienced practicing engineer and has managed several projects successfully. And hands on experience gained by the author have been added in the various chapters of this book. And that's what separates this book from other books on this subject.
This book can be useful to the teachers and students of Construction Management as well as to managers of financial institutions who finance construction projects. In addition, this book has enough material on offshore engineering to support a three semester hours’ worth credit course.

Text Description automatically generatedPreface-1
This book is a result of many years of actual hands-on experience and has been written with the specific goal of helping students and practitioners of construction management. It is envisioned that it will also be useful to executives with general business or financial backgrounds to receive an introduction to the basics of construction management. And to help them appreciate the vast expanse of building an energy infrastructure onshore as well as offshore, from exploration, transportation to production and refining of hydrocarbons and petrochemical.
Construction management requires multidisciplinary technical expertise, combined with extraordinary patience and diplomacy, to successfully manage construction projects on time and under budget. The basic principles of construction management are applicable to all types of energy infrastructure. However, technical knowledge specific to the infrastructure project at hand will go a long way towards the successful completion of a project.
Most publications deal with one or more aspects of construction management, such as scheduling or cost management, without providing an overall understanding of construction management in the construction energy industry. This book is intended to fill this gap by providing an overview of all types of energy construction, the various contract types, bidding process, as well as contract negotiations. The book follows a sequential arrangement of its chapters similar to the sequence of activities on a construction project.
Specifics such Scheduling and Cost Management fall under the heading of Project Controls in the construction management field, but there are many other constituents of construction management, including Quality Control and Safety, which have been dealt with in this book as well.
Construction Management is performed by a team of experts headed by a Construction Manager. In oil and gas exploration, production, refining and petrochemical projects, the Construction Manager generally reports to a Project Manager or a Project Director.
Energy infrastructure projects are typically multi-million-dollar projects with large construction management organizations. Whether a project is built onshore or offshore adds an additional layer of complexity.
Generally, the construction industry infrastructure is divided into three types:
I. Industrial
1. Onshore (E&P facilities, refineries, petrochemical plants, etc.)
2. Offshore (oil and gas facilities, gathering systems, pipelines, etc.)
II. Commercial
1. Institutional
2. Business (hotels and apartments, high-rise buildings)5
III. Residential (single or multi-story)
IV. Infrastructure (Bridges, Tunnels & Shipping Terminals)
Regardless of the type of construction, the basics of construction management remain the same. However, offshore construction is very different from onshore construction in size, shape, construction techniques, materials, equipment, risks and especially the cost. Therefore, it is important to understand why it is so. And for this reason, the book has devoted several chapters identifying the various elements of offshore projects to impart this know-how:
Offshore platforms
Offshore pipelines
Shipping terminals
The most common principles/concepts of Construction Management are universally applicable to all type of projects onshore or offshore. These concepts are discussed in detail in the following chapters. This information should enable the reader to gain a basic understanding of construction management as it relates to energy infrastructure.
It is assumed in the book that we are dealing with a relatively large industrial project (e.g., offshore platform, power plant, petrochemical complex), which would require a fully staffed organization with all construction management specialties. Therefore, knowledge of the material provided in the book is a minimum requirement for a construction manager of such a large project. While the same construction management principles apply for smaller projects, some of these techniques would need customization to suit the size and type of a project, however.
Preface-2
This second edition contains several valuable changes, additions, and revisions in this book. Chapter-1 through Chapter-3 have been revised and several items added in them. The various construction equipment & Geotechnical information for site preparation and foundations have been added in Chapter-3. Chapter 5 through 19 have been thoroughly revised and several relevant information have been added to supplement the existing materials. Additional construction materials information has been added in Chapter 9. Chapter 10 (Project Execution) has been thoroughly revised and enlarged with all aspects of project execution processes included. Chapter 13 (Cost Management) has also been enhanced and revised to include such topics as estimate types & estimate basis, contingency, and escalations allowances, etc. Similarly, other chapters dealing with such diverse topics like negotiations and qualifications of successful negotiators; progress payments & their accuracy determination; the various ways to deal with conflicts, including litigations & arbitrations. These additions and revisions were based my own teaching experiences and by finding the inadequacies in the book to cover certain important topics. And fulfillment of these requirements has led to the addition of more than fifty pages in this new Edition (2) of this book, as compare with the first edition.
Any suggestion for improving the book would be very much appreciated

CHAPTER 1
Introduction
Construction Management is a multi-disciplinary profession, requiring a unique blend of science, technology, and even liberal arts. Most construction management personnel come from engineering backgrounds, Civil Engineering in particular. However, in addition to a strong technical background, the Construction Management professional should be familiar with disciplines such as economics, sociology, psychology, law, and communications.
Typically, a Construction Manager oversees the overall Construction Project and heads a Construction Management organization. Depending upon the size and complexity of the project, the Construction Management organization includes several subject matter experts (SMEs), such as a cost engineer; scheduler; quality manager; safety engineer, and others. As the head of this organization, the Construction Manager is responsible for bringing the engineered design on drawings to a physical reality, such as a building, a bridge, or a power plant.
Many engineered objects around us (e.g., houses, cars, roads, bridges, buildings, airplanes, ships) as well as smaller devices such as watches, computers, and so on, have passed through four stages of evolution, before reaching the market. These stages/phases are¹:
PROJECT DEVELOPMENT STAGES
Conceptual Phase
This is the first stage of any project, wherein an idea is born out of necessity or strategic thinking by an individual or business to produce something to fill a gap in the market.
FEED (Front End Engineering & Design)
As this idea catches momentum based on the interest of management, engineers explore it further for its feasibility as a possible project by performing preliminary engineering and cost analysis.
Detail Engineering
Based on the FEED results, organization may end the project, or decide to proceed with the project to build it. In the later scenario, the next phase is Detail Engineering, wherein engineering is finalized, and drawings are prepared. And thereafter the project is awarded to a builder/contractor for construction.
Execution phase
(Detail engineering, fabrication, construction, commissioning & start up)
In the oil and gas industry, the Execution phase starts before the actual end of the Detail Design. This is when the Construction Management organization is established, and the contractor is selected for construction.
While all phases as stipulated above are equally important, construction part of the fourth phase is where the proverbial Rubber meets the Road
cliché’ applies. It is important to note that this is the phase where the initial thoughts/concepts are refined, and the engineering drawings and specifications are transformed into a physical reality.
Each of these four phases require precise planning and management of activities to
achieve successful completion before moving into the next phase. Additionally, planning and management required for Construction requires even more precision. The reason for this additional emphasis is that any mistakes made in first three
phases, although not accepted as routine, can be rectified on paper easily and with little impact on cost than fixing a construction mistake.
Construction phase mistakes can be as much as ten to several hundred times costlier as compared with those in other phases, especially in the offshore construction.
The following are a couple of real-life examples wherein construction mistakes ended up costing the owners millions of dollars to correct. Had these mistakes been identified during earlier phases, it would have cost a fraction of what it cost to fix these after the construction.
In first instance, a subsea pipeline design had assumed the gas to be transported via this offshore pipeline to be sweet
or containing no H2S gas. This was an erroneous assumption and ended up costing the company tens of million dollars to replace the pipeline with one that was suitable for transporting sour
gas containing traces of H2S gas.
In the second instance, the mistake was a result of faulty pipeline fabrication. Pipeline cladding installed inside the line-pipe separated, while the pipeline was in operation. Consequently, this pipeline corroded and had to be abandoned. A new pipeline system had to be installed, costing the company hundreds of million dollars. If the mistake had been caught during fabrication, the cost would have been perhaps one tenth of what it eventually cost to replace the pipeline.
All projects go through the same four phases of evolution, yet each project has a distinct set
