Digital Execution Architecture—Why Change
Just a few short decades ago, all industries were paper based. Engineers drew diagrams by hand and built physical models of their designs. Facility owners slogged through hard-copy reports in massive binders, and fabricators and contractors stuffed their bookshelves with archives of codes and references.
Gradually some industries realized the benefits of using computer-based applications, and those that adopted these processes quickly outpaced their peers in productivity, efficiency and quality. However, many of the processes supporting these systems and the communication of information between project participants relied on paper and spreadsheets. This led to information silos and a slow and cumbersome transfer of information throughout the project that was open to error. For example, facility documents and data were stored in an electronic document control system (EDMS) that is difficult to search and find the needed information quickly. This scenario is all too familiar to most project participants.
The digital execution architecture for developing capital projects and operating capital assets is a way of overcoming the problems with isolated information systems and paper-based work processes. In this model, the information systems are fully integrated and project participants can easily and quickly access information through a technical data portal—a centralized online location that project participants can access in a timely, secure manner over the internet—without having to rely on paper copies for key asset information. Unfortunately, the oil and gas industry has been slow to adopt the digital execution model.
The current economic environment makes it a challenge to justify building and operating a capital asset. The development of these capital assets has a tendency to go over budget and schedule.
The digital execution architecture is a means of delivering assets in less time and on budget and reducing the operating costs of the asset throughout its lifespan. This new approach has benefits for both the owner-operator and the EPC charged with the responsibility of designing, procuring and constructing the capital asset.
High-Level Benefits and a New Relationship
For the EPC that uses this model, they can offer their customers a high-quality product that typically costs 10 to 40% less than a project executed using the traditional model when including front-end engineering design and detailed engineering. These cost savings are from:
- reduced workforce hours resulting in a shorter engineering schedule
- enhanced collaboration between project participants, including clients and third parties
- improved data accuracy, transparency, accessibility and security
For the owner-operator, the total installed cost (refers to the final cost of designing, fabricating and building a capital project or industrial asset.) of the design and build of the asset is lower. If the owner-operator manages their assets using digital execution architecture during the operations phase, then the refers to the total cost of owning an industrial asset throughout its full lifecycle, from design and construction through operations and decommissioning.... Read more (TOC) will also be reduced.
There is a direct relationship between data accuracy and cost reduction—as project data improves, the likelihood of reducing project costs increases.
- The execution schedule is shorter for digital execution
- Project tasks can be accomplished in less time because less productive activities are eliminated
- Less time is lost to rework because of poor data quality
- Decisions can be made faster and more effectively
- Less time is taken to chase data required to complete a task
Adopting the digital execution strategy means cultural and organizational changes for both the EP firm and owner-operator.
Historically, engineers create a deliverable, polish it up, and hand it over to the client for their feedback. The client sits on it and marks it up and then pitches it back over to the EP, with the deliverable going back and forth as many times as it takes to get it right.
By allowing the owner-operator access through the A web-based application that allows users to organize, validate and collaborate on asset data and documents regardless of their source and location.... Read more, both parties have the ability to continuously work and contribute to the progression of the deliverable. This means that clients will see unfinished work and work that might contain errors, but in a collaborative environment, this is all part of the process of getting the product to its final state. This is something that both parties need to come to grips with.
Ideally, the end goal is achieved quicker because there is improved communication and understanding of needs, which means less recycling. In addition, the owner-operator has visibility into what their contractor is doing and can see progress and status. Such a relationship must involve cooperation, accountability and a less adversarial approach than that typified by the traditional execution model.
For the EP, the use of the digital execution architecture means rethinking how work is done internally. Increased transparency between disciplines improves communications and reduces the time waiting for teams to do certain tasks and passing that information to the next team. Communication is much better and there is less interference with people from one group having to interrupt another team. New business processes must be developed and training provided to support project staff in getting the most out of the new tools.
Potential cost savings could arise from using different contracting strategies for bidding EP work. Using the digital execution architecture with its high degree of data integrity reduces risk in project development, and risk drives behaviour and price. An EP is less likely to accept a lump-sum contract and assume all the risk knowing that there is uncertainty around data quality. This means that other contracting methods are used, such as a cost-reimbursable model, which can leave the owner-operator open to cost escalation.
Using the digital execution architecture provides greater certainty around cost and schedule by reducing sources of risk. For the owner-operator, this makes it possible to consider using one EPC to conduct all the phases of a project’s development and further reduce the TIC. Even if an owner-operator wished to retain different contractors for different project phases, the quality of the digitally executed design work handed over would mean less risk for the follow-on contractor.
Benefits by Discipline

Read more benefits every stakeholder group, be it client, EP or vendor. Moreover, the benefits for one team have ripple effects on other groups.
For example, designers see tangible time and effort savings that create value for facility owners by improving the quality of their designs and lowering project costs. The benefits of the digital execution architecture for the project participants fall into several categories:
- the timeliness and ease of access to data
- a high degree of data integrity
- ease of use of systems
- ability to produce meaningful reports
- smaller work teams
Timeliness and Ease of Access to Data
One of the biggest problems people have on a project is finding information. Typically, on a non-digital project when information is needed for a task, the information requestor must ask an information owner to provide some information. This request goes to a work queue and is completed by the information owner when there is time. The information requestor might need to follow-up with the owner several times before the request is completed. It might take two or three day to complete the request. Meanwhile, the requestor cannot progress their task. In addition, information requests might need to be issued to multiple information owners, which can complicate matters further. This scenario plays out repeatedly among various information requesters and owners throughout the project’s development.
In the digital execution model, all the information is housed in one place: the technical information hub. Information updates between applications in the architecture can be automated as well. For example, an MTO is automatically loaded every night into the is a provider of industrial and engineering software that is driving digital transformation in capital-intensive industries. AVEVA software solutions include engineering, asset performance, planning and operations, and control and monitoring.... NET model. It’s in a certain spot, it’s always there and always current, everyone knows where it is. Just click on the P&ID and the information is there.
Data with Integrity
Unfortunately, miscommunication around data can cause big problems. Companies end up making decisions with old, incomplete information that is riddled with errors. In fact, surveys show that up to 54% of our decisions are made with poor-quality information. If data cannot be found, it cannot be used or analyzed, and the ability to make meaningful decisions is lost, which increases execution risk. Time is lost trying to make decisions—consequently, projects take longer to execute. Weak or failing knowledge architectures can cost you money and dulls your competitive edge.
In addition to finding information quickly and easily, having confidence in the data is a tremendous benefit. Knowing that data is current and correct means that it can be acted on without needing confirmation.
Ease of Use
Adopting a digital execution model does not necessarily require the learning of new software applications so that people can do their jobs. The model can incorporate well-established applications that are familiar to the various project disciplines. Using familiar systems reduces barriers to acceptance. A CAD designer will still use a familiar CAD application to do his or her work. What changes is how information is distributed to these applications and how information is retrieved from the technical data hub. Once people know where to find the information and the ease with which it can be found, then they are able to work effectively.
The digital execution architecture enables instantaneous comparison reports. In a non-digital model, reports would run on a predetermined cycle and be distributed to the project participants. The report might not be up to date because work teams have not loaded their data. Nevertheless, that was all people had to work with, so they used it, and another exercise in data validation would ensue.
In the digital model, anyone can run a report to compare data to verify its timeliness before using the data in their own work.
Digital execution eliminates many tedious, time-consuming non-core tasks, meaning that fewer people can do the same amount of work in less time while improving the quality of the work.
One significant time-consuming task that project teams face is checking work or document packages. A package of information would be assembled and handed off to checker to review where it would sit in a pile waiting for review. The package represents a point in time, so by the time the package is reviewed, some of the data could be out of date.
A manual check can be one of the more expensive processes on a project. Using the digital model as the checking tool can reduce the time spent checking things manually, which is a significant efficiency. In addition, the data is accurate, so there is little risk from rushing something through checking and hoping that the data was correct.
The efficiencies of the digital system are so significant that team sizes can be reduced.
Full System Integration
Digital engineering environments present various opportunities to reduce project costs, and they all relate to enhanced system integration. When everyone has real-time access to the work produced by others, they execute day-to-day tasks more efficiently and make decisions based on information that is more accurate.
Regardless of whether the project is a greenfield or brownfield facility cost saving will accrue from:
- Increased data accuracy and security
- Improved client collaboration
- Enhanced cross-function integration
- Reduced handover costs
- Streamlined design and fabrication integration
Integrated Engineering Workflow
Data from vendor systems is seamlessly integrated into the system architecture, which supports a broad variety of industry-standard file formats and data structures. This integration benefits stakeholders in all project phases. Early advantages include access to design information as it progresses, and a convenient “one stop shop” for all project deliverables. Value is added during execution and construction phases by making comprehensive, reliable information available at the site. Operations and maintenance also benefit from improved as-built drawings, simplified monitoring, and faster access to site data and innumerable other impacts.
