Frequently asked questions about PDRI
Why is PDRI critical?
Who uses PDRI?
Engineering Firms & Contractors Engineering firms and contractors also use PDRI. It is used as an alignment tool in the development of an Owner’s business objectives, to clarify requirements, improve cost and schedule estimates, and coordinate execution planning. Contractors also use PDRI to assist in risk assessment for a Request for Proposal (RFP) on a project where scope definition has been completed by the Owner or another engineering firm.
When is PDRI used in the project lifecycle?
How is PDRI structured?
The PDRI methodology supports a comprehensive assessment of scope definition. Templates are organized in three sections for systematic assessment of the:
- Basis of project decision – the business objectives and drivers
- Basis of design – processes and technical information required
- Execution approach – for executing the project construction and closeout
Each section is broken down into categories and elements. The element is the lowest level of the index where the assessment of scope definition is conducted.
Is PDRI applicable to all capital projects?
The Industrial template is targeted for projects that provide an output in terms of assemblies, sub-assemblies, chemical compounds, electricity, food or other marketable goods. Examples include power plants, chemical plants, oil & gas production, refineries, water and waste treatment, and manufacturing facilities.
The Building template is designed for commercial building projects. Examples including offices, schools, medical facilities, institutional buildings, warehouses, parking structures and research facilities.
The Infrastructure template is targeted for projects that involve linear construction with extensive public interface and environmental impact considerations. Examples include railways, highways, pipelines, transmission and distribution and canals.

What is PDRI MATRS?
PDRI MATRS (Maturity and Accuracy Total Rating System) is an extension of the PDRI Industrial template that assesses both the maturity and accuracy of FEED in large, complex industrial projects. It is best suited for large, complex industrial projects where total installed cost is greater than $10M USD, construction duration is at least 9 months and the core team consists of more than 10 members.
FEED is defined as “Front End Engineering Design”. It is a component of the front end planning process referred to as Detailed Scope (Phase 3).
In addition to the core benefits of PDRI assessments, PDRI MATRS will improve the degree of confidence in the level of maturity of FEED deliverables to serve as a basis of decision at the end of Detailed Scope (Phase 3). This typically represents 30% of engineering and design complete and is within the Class 3 cost estimate range (AACEi).
Definition level criteria for all elements
One of the key resources developed as part of the PDRI MATRS tool was definition level criteria for all elements. This is a valuable asset for increased consistency in facilitation. The score guidance provides increased clarity on specifically what must be completed for each element and definition level.
There are 46 of 70 elements that are directly related to FEED. They span all three sections of the PDRI Industrial template and maintain the same weightings and definition level values as the standard PDRI Industrial template. The normalization formula transforms the PDRI score of these elements into a Maturity percentage. A higher maturity score indicates better scope definition. By the end of Detailed Scope (Phase 3), the target score is 80% or higher.
The Accuracy Factors have been added as a new section. This set of factors involve the people, teams, processes and resources that create the environment where a mature FEED can be developed. There are 27 factors organized into four categories. Their weightings were determined based on CII research results and are displayed as a percentage. The target score at the end of Detailed Scope (Phase 3) is 76%. The higher the score, the better.
