WHAT IS A MAJOR EPC PROJECT


INTRODUCTION


In my blogs I have been talking about the management of major projects. Though there is no specific criteria, but it is a generally accepted that a Major Project can be identified as a project with a minimum estimated total installed cost (TIC) of US$ 250 million and accompanied by a high level of complexity. A major project is a large-scale investment project and generally attracts a lot of public interest due to substantial impact on communities and environment. There are a variety of major projects and each project requires a distinct management approach and execution strategy requiring specialized technical skills, execution strategies and the adoption of strategic management philosophy. For example a project to construct a highway may require a different set of skills and execution strategies as compared to a large airport. Similarly the development of a housing complex may require a totally different skills and execution strategies as compared to an offshore oil drilling project.

It is observed that Oil & Gas, Energy, Process and Power projects form a distinct group requiring a common platform of project management techniques. This blog focuses on the management of this group of projects.

With the increase in technological growth and globalization of industry, the scale and complexity of projects continue to increase. The owners have started to realize that aggregating the processes, power, technology and infrastructure generally leads to significant improvements in project profitability. Only a few project managers hold the skills and processes required to plan and deliver these projects. In the following blogs, we will discuss the required skills, processes and procedures to successfully deliver these major projects in an increasingly challenging project delivery environment.

1.         What is EPC


EPC stands for Engineering, Procurement and Construction.  It is a common form of contracting arrangement for the execution of Oil & Gas, Chemical and Process industry. Under an EPC contract, the contractor takes complete responsibility of engineering the facility, installation, procuring the necessary equipment and materials; installing and constructing, either through its own labor or by subcontracting a part of the work.

E
stands for engineering only. Such contracts are awarded in the initial phases of the project to carry out the basic design or FEED work. FEED stands for Front-End Engineering and Design. For major projects, it is becoming a common practice to split the project into two phases; in the first phase the contractor sets the design parameters that define the work scope, prepare WBS, estimates, and break the work down into work packages to a level sufficient for the award of a detailed EPC contract. The second phase consists of the EPC or EPCM phase.
EP

When the execution scope is restricted to engineering and procurement only; this is referred to as an EP contract. This is often done in situations where the Owner has a preference for doing the construction through its own resources or intends to award the construction work to a third party.

EPCM
When scope is restricted to engineering, procurement and construction management only, this is referred to as an EPCM contract.

2 .        EPC AGREEMENTS


The EPC (or EP or EPCM) agreements are of four major types:

a)         LSTK CONTRACTS

LSTK stands for Lump Sum Turn Key. It combines the Lump Sum (LS) part that refers to the payment of fixed fee under the EPC contract. The second part TK stands for Turn Key. TK specifies that the scope of work includes the commissioning and start-up of the facility to operational status.



b)         LUMP-SUM CONTRACTS

Under Lump Sum Contracts, the EPC contractor’s responsibility is limited to satisfying the agreement terms (generally till the Mechanical Completion) for a fixed fee. Some agreements cover the pre-commissioning activities as well. The owner takes over the charge of project and completes the rest of the work including commissioning, trial runs and plant operations.

c)         COST PLUS CONTRACTS


Under Cost Plus Contracts, the EPC contractor is provided a specified percentage profit over and above the actual cost of Engineering, Procurement and Construction work. These contracts are quite popular with the Oil & Gas and Petrochemical projects. Under these agreements, the owner has a good presence in the project team with most of the decisions being taken jointly.

3.         COST PLUS PROJECT TEAM

Under the Cost-Plus contracts, project team consists of the Owner, the EPC Contractor and third parties engaged on specific jobs. On account of the complex responsibility, decision making and approval process, the formation of the project team under such agreements needs a great deal of effort. It is therefore necessary to develop a detailed responsibility matrix to define the responsibility and approval process of each team member.  A detailed discussion on this subject will be done under RASCI blog.   

4.         ALLIANCE AGREEMENTS


Alliance agreement is a model of co-operative work model that had become very popular in the EPC industry during 1990’s.  Excessive cost over-runs and project delays started a re-thinking in the industry leading to the alliance agreements. The alliance contracting concept evolved as a response to two perceived failings in the traditional model of EPC business. The first was the excessively adversarial nature of the EPC contracts, driven by the traditional LSTK agreements with liquidated damages. The second was the barrier to outstanding project performance that was the need of the day.

PROJECT MANAGEMENT COMPONENTS

INTRODUCTION 

The management of most of major Projects is generally contracted out by owners to organizations having expertise in the field. With this in view, owner satisfaction becomes an important criterion for the project management team. The management team focuses on the following five major components leading to the owner satisfaction:
 

1.       Scope
2.       Time
3.       Cost
4.       Quality and
5.       Performance 

 

1.    Project Scope


Project scope describes the work required to deliver the product or service with the intended requirements to the satisfaction of owner. It describes the intended quality, features, and functions of a product or a service often in minute detail. Every project produces a unique product that is either a tangible item or service. Project owners usually have some expectations about the features and functions of products which are detailed out in the project scope document. Documents that outline this information are generally called product specifications. A service or event usually has some expected features as well.

A Scope document identifies the requirements to achieve the defined end results. The document is expected to define what the project is supposed to accomplish, and a specific description of the end result expected be accomplished. A major component of scope is the quality and performance of the end product.

The scope document is meant to ensure that everyone on the project team understands what is expected of them during the execution of the project. In addition, all work that can be reasonably predicted must be ascertained and reported in the document. Suitable scope definition is essential for the success of the project and needs to be given due consideration and thought.

The scope and objectives are always project specific. Most of the major projects do have common features on the scope document which is generally broken down under the following Sections:

2.    Time Component

 2.1              Introduction 

Every project has to have a start date and an end date as no project can be expected to continue indefinitely. Every project has some element of a time constraint and most major projects also have many well-defined milestones to be met. As an example a project may have the following contractual milestones:

1)       Completion date Basic Engineering
2)       Ordering of Major Equipment
3)       Substantial completion of detailed engineering
4)       Start of Construction work
5)       Mechanical Completion
6)       Project commissioning
7)       Handing over

While developing the project schedules, time required to complete each and every activity is estimated. Depending on the interrelations and dependencies, the time required to complete a task on the Work Breakdown Structure is estimated. Through the scheduling techniques, project activities are prioritized, critical paths are identified and the dependencies between activities are re-worked and the resource requirements are estimated.  The schedules are rolled up using the schedule networking techniques to arrive at the project milestones.

Schedule management is a critically important skill for any successful project manager. It is observed that the Project Managers who succeed in meeting their project schedule have a good chance of staying within their project budget. One of the common causes of budget over-runs is the lack of proper schedule management. 

2.2              Project Schedules 


Project schedule is simply a graphical illustration of a project’s execution plan.  It organizes the activities and tasks into a fixed time frame taking into account the inter-dependencies among each other. Each task and activity is allotted a completion time duration. The schedule represents the project plan and is vigorously monitored to ensure that work is being performed within the allotted time frame.

The project schedule is the core of the project plan and is used by the project manager to commit people to the project. Schedules are also used to communicate final deadlines and to determine the resource needs and serve as a checklist to make sure that every task necessary is performed. 

Project Schedule is an invaluable tool for organizing, evaluating, and forecasting how a project is to be executed and provides project team members with an understanding of the interrelationships between activities and serves as a vehicle for achieving buy-in from all of the team members. Each team member has a role and commitment for meeting the objective. Its greatest value is its ability to identify the Critical Path i.e. those tasks, activities, and duration that dictate the overall duration of the project. As problems arise, the schedule can be used to evaluate alternative paths for achieving success.  The schedule can provide guidance in identifying problems early in a project.  If, for instance, a project activity was scheduled for three months, and in the first month only twenty percent of the task was completed, the team can entertain methods to recover the lost time.

There are numerous methods and paths of achieving the project goals; the project schedule illustrates one such method for achieving the stated objective within the required time frame.  There could be many other execution plans that can result in a successful project but different plans result in changes in duration, cost and quality of the project.
 


3.    Cost Component

3.1              Introduction
Every project has to have a budget and it is one of the critical responsibilities of the project manager to ensure that the project cost remains within the pre-assigned budget and preferably remains under-run. Budget over-runs always reflect very poorly on the management team. This is where the cost control system comes to the rescue of project manager.

Project cost has a broader meaning and includes all of the resources that are required to complete the project. It includes the people, the machinery and equipment that do the work, the materials they use, and all of the other events and issues that have a monetary impact or need someone’s attention in the project. The project cost may have the following components which need to be monitored and controlled:
   
1)       Home-office man-hour cost
2)       Home-office overheads
3)       Bulk material costs
4)       Equipment costs
5)       Construction direct labor costs
6)       Construction material costs
7)       Contractor costs
8)       Indirect costs
9)       Other misc. costs

3.2              COST CONTROL
Project cost control is comparing actual and committed project cost against the control cost or the budget. It is refers to knowing exactly what is committed, what remains to be committed, what is incurred, invoiced, approved for payment, paid and analyzing the variance. This makes cost control very critical to the success of a project. No major project is initiated without first establishing an effective cost control system. When it comes to project management, cost control can make or break a project’s budget. Cost control can best be achieved by setting up a budget which is consistent with plans for actual spending. Another important aspect of cost control involves collecting the actual and committed cost and preparing and analyzing reports for the cost management.
 


COST CONTROL PROCESS
The approved budget estimate is categorized into the Cost Code of Accounts and loaded into the project cost system. This serves as the control budget. Actual costs are continuously recorded in the cost system from accounting transactions. Cost reports will be generated by cost code for the total project. By using this system, a budget versus actual expended comparison is made by account.

Deviations are identified and project management alerted so that timely corrective action may be taken.
The Cost Control Process involves the following steps:

1)       Budget Finalization
2)       Cost Control Tools
3)       Cost Coding & Loading
4)       Cost Capture
5)       Cost Schedule Relationship
6)       Change Management
7)       Data Evaluation
8)       Risk Analyses
9)       Forecasting
10)   Contingency Management
11)   Cash Flow
12)   Cost Reporting

These topics will be discussed in detail in other blogs.

4.    Quality Component

4.1              Introduction

Quality is a measure of fitness for use and represents meeting or exceeding the needs and expectations throughout the life-cycle of the project or what-ever is being delivered. The items being delivered may include the designs, drawings, equipment or the complete plant.

Quality is an important aspect of Project Management. Every major project has to have systems in place for proper quality management. Quality Management is the management of systems and procedures that determine the quality policies, objectives, and responsibilities so that project outputs are delivered fit-for-purpose. The purpose of a project Quality Management Plan is to define the overall quality philosophy for the Project, the organization and responsibilities for achieving the desired quality, and the general quality management activities to be performed.  It addresses the quality requirements for Engineering, Procurement, Construction, sub-contracts and related project management activities.

The quality requirements for a project apply to:
1)       Project Management
2)       Project Controls
3)       Engineering
4)       Procurement
5)       Project Administration
6)       Objectives

4.2              Quality Evaluation
From the project point of view, the quality is judged on the following criteria:
1)       Meeting the project schedule and targets
2)       Project completion within the Budget
3)       Meeting the product specifications
4)       Operational suitability
5)       Proper and accurate documentation
6)       Compliance with standards
7)       Acceptable maintenance costs

4.3               Quality Plan
 
All major projects have a Project Quality Management Plan, the purpose of this plan is to define the overall quality philosophy for the Project; the organization and responsibilities for achieving quality; and the general quality management activities to be performed by the project team. 
Quality Management Plan will be discussed in future blogs.

5.    Project Performance Component

 
Successful project managers control projects by carefully monitoring, measuring, and managing the project performance. Usually performance is measured in the fundamental areas of budget and schedule, but the performance of major projects includes areas like project’s scope, quality and owner satisfaction along with schedule and budget.

Performance Evaluation
Once the monitoring (also known as measuring) is done, it is essential to evaluate and analyze the data so collected. Given below are some of the areas of analyses:
 
1)       Progress evaluation
2)       Progress Performance Reports
3)       Monitoring the current status of project against the base line schedule
4)       Monitoring the current status of project against the base line cost estimates
5)       Establishment of Critical Path
6)       Forecasting project milestone completion targets
7)       Forecasting cost to complete each unit
8)       Estimation of progress performance
9)       Estimation of project productivity figures
10)   Identifying trends and change orders
11)   Identification of critical activities likely to impact the project
12)   Evaluation of schedule and cost risks
13)   Forecasting final project completion schedule and cost

Project Performance will be discussed in detail at a later stage.
