Why Food Processing Projects Break Down Before Construction

Addressing the engineering data challenges behind complex food processing facilities

Food processing manufacturers face increasing pressure to expand production capacity, modernize aging facilities, improve operational efficiency, and meet demanding food safety requirements. As production environments become more sophisticated, so do the engineering projects required to support them.

Consider the complexity of a modern food processing facility. Mixers, conveyors, pumps, heat exchangers, packaging systems, HVAC equipment, piping, and structural components must operate together within carefully planned production environments. Much of this equipment comes from different manufacturers, each using its own CAD software, modeling practices, and engineering standards.

Bringing these systems together requires more than coordinating equipment specifications and installation schedules. It requires engineering information that can be reliably exchanged, interpreted, and incorporated into a complete facility design.

Unfortunately, the CAD models supplied by equipment manufacturers are not always suitable for these downstream applications.

Models originally developed for detailed mechanical design may contain thousands of unnecessary components, complex internal geometry, or features that provide little value during plant layout. Differences in CAD formats and geometric quality can introduce additional complications.

For engineering, procurement, and construction (EPC) firms, these issues create a significant challenge: how can complex equipment models from multiple suppliers be incorporated into a unified plant design without introducing unnecessary engineering effort, performance limitations, or project delays?

The answer increasingly depends on how effectively engineering data is prepared before entering the facility design process.

The Complexity of Engineering Data in Food Processing

Food processing facilities are particularly challenging because of the volume and diversity of equipment involved.

A single production line may incorporate equipment from dozens of suppliers, with models delivered in formats such as SolidWorks, Inventor, STEP, or other mechanical CAD representations. These models are typically created to support the equipment manufacturer's own design and production requirements rather than the needs of the engineering organization responsible for integrating them into a facility.

For example, a detailed industrial pump model may include internal shafts, bearings, seals, fasteners, and numerous small geometric features. While these details are essential for manufacturing and maintenance, they may serve little purpose when the model is being used to determine equipment placement, piping connections, or clearance requirements.

When hundreds of similarly detailed models are combined, the resulting plant assembly can become difficult to manage:

• Large files consume computing resources
• Slow model loading and visualization
• Compatibility issues between engineering applications

The challenge becomes even greater during facility expansions and modernization projects, where newly supplied equipment must be integrated with existing infrastructure and legacy engineering information. In these environments, engineering teams need to preserve the dimensions, interfaces, and geometric features relevant to plant design without carrying unnecessary complexity into every downstream workflow.

The Hidden Impact on Engineering Productivity

The consequences of poorly prepared CAD data extend beyond software performance.

When incoming equipment models are too complex or incompatible with the receiving design system, engineers may need to manually remove unnecessary features, rebuild geometry, or create simplified representations before the models can be incorporated into the plant layout.

These activities introduce additional engineering effort that is rarely visible in the original project scope. Consider an EPC organization coordinating equipment models from multiple vendors. Each supplier may provide several revisions as equipment specifications evolve. If every revision requires manual simplification, the preparation effort grows throughout the project.

Design teams may also encounter delays when large assemblies become difficult to navigate, models fail to import, or geometric inconsistencies prevent downstream applications from processing the information correctly.

These challenges can affect several project activities, including:

• Facility layout and coordination: Large equipment assemblies can reduce the responsiveness of plant design environments and complicate multidisciplinary coordination.
• Design reviews and clash detection: Excessive geometric detail can make it more difficult to navigate and evaluate complete facility models.
• Engineering collaboration: Incompatible or unnecessarily complex models can require additional preparation before being shared between project participants.
• Project revisions: Updated supplier models may need to undergo the same manual simplification process repeatedly.
• Intellectual property protection: Detailed equipment models may contain proprietary internal features that suppliers do not want distributed beyond their organization.

For food processors investing in new production capacity, these inefficiencies can affect engineering schedules well before construction begins.

Rethinking How Equipment Models Are Prepared for Plant Design

Traditionally, engineers have addressed complex equipment models by manually removing unwanted geometry or remodeling components into simpler representations. While effective for individual models, this approach becomes difficult to sustain when projects involve hundreds of equipment assemblies and frequent design revisions.

A more scalable approach is to establish a repeatable process for preparing incoming CAD data before it enters the broader engineering environment.

This is the purpose of CADfix PPS.

Developed by International TechneGroup, Inc. (ITI, a Wipro company), CADfix PPS automates the simplification and preparation of complex mechanical CAD models for downstream plant and process engineering applications.

Rather than requiring engineers to manually modify every supplier model, CADfix PPS can identify and remove unnecessary geometric detail while preserving the features needed for facility integration.

Its capabilities address several common requirements:

1. CAD interoperability and geometry preparation - Equipment models frequently originate from different CAD systems. CADfix PPS supports the import and processing of major mechanical CAD formats without needing multiple licenses, helping organizations prepare supplier models for use in downstream plant design environments.
   
   
2. Automated geometry simplification - Detailed equipment models often contain small parts, holes, fillets, rounds, internal components, and other features that are unnecessary for plant layout. CADfix PPS provides automated simplification capabilities to remove or reduce this complexity while retaining important external geometry and connection interfaces.
   
   
3. Assembly-level simplification - Complex equipment assemblies may contain numerous individual parts that contribute little to the overall facility model. CADfix PPS supports simplification at the assembly level, allowing engineers to process equipment groupings more efficiently rather than addressing every component individually.
   
   
4. Intellectual property protection - Equipment suppliers may need to share accurate external models without exposing proprietary internal designs. CADfix PPS can remove internal components and sensitive geometric details while retaining the information necessary for equipment placement and integration.
   
   
5. Repeatable engineering workflows - By establishing consistent model preparation processes, organizations can reduce the need for manual intervention when new equipment models or revisions are received.

The objective is not to remove as much geometry as possible. It is to retain the information necessary for the intended engineering application while eliminating detail that unnecessarily increases model complexity.

Use Case: Hawk Engineering Improves Plant Design Performance

Hawk Engineering Group provides a great example of how standardized CAD simplification can improve industrial facility design. Working across multiple industries, including food and beverage, Hawk routinely incorporates large vendor-supplied equipment models into comprehensive plant layouts.

As project complexity increased, its engineering teams encountered slow model loading, rendering delays, application instability, and time-consuming manual defeaturing. Hawk implemented CADfix PPS to establish a more efficient process for preparing incoming equipment models.

The reported results included:

• Approximately 85% reduction in model size
• Five hours of engineering time saved per model
• 10× faster model performance
• Elimination of CAD crashes

By reducing the time required to prepare equipment data, Hawk improved the usability of its facility models and allowed engineers to devote more attention to design and project execution.

The example is particularly relevant to food processing organizations because it demonstrates how CAD model preparation can support the multidisciplinary engineering workflows used in complex industrial facilities.

Supporting Facility Modernization and Brownfield Projects

The need for effective CAD data preparation becomes particularly important when manufacturers modernize existing facilities. Unlike greenfield projects, where engineering teams can establish new design environments from the beginning, brownfield projects must account for existing equipment, infrastructure, and historical engineering information.

A food manufacturer expanding a packaging line, for example, may need to integrate new machinery into an operating facility while maintaining existing piping routes, structural constraints, maintenance access, and production requirements.

The engineering information supporting that facility may have been created over several decades using different CAD applications and modeling practices. As new equipment is introduced, its geometry must be incorporated into the existing layout without making the overall plant model unnecessarily difficult to manage.

CADfix PPS helps address the equipment integration aspect of this challenge by simplifying incoming mechanical CAD models and preparing them for downstream use. While model simplification does not resolve every challenge associated with legacy engineering information, it can prevent new equipment data from introducing additional complexity into already demanding facility design environments.

For manufacturers undertaking phased expansions or equipment replacement programs, this supports a more manageable approach to maintaining and updating digital plant models.

Why Engineering Data Preparation Matters Beyond Design

As food processing manufacturers expand their use of digital engineering, the value of reliable CAD information extends beyond the initial facility design.

Plant models increasingly support activities such as equipment coordination, construction planning, maintenance access evaluation, digital visualization, and the development of digital twins.

However, these applications do not necessarily require the same level of geometric detail.

A model used for manufacturing an industrial mixer may need a complete representation of its internal components. A facility layout may only require its external dimensions, mounting locations, and connection points. A maintenance planning application may require additional information about service clearances and removable components.

Using the same highly detailed model for every application can introduce unnecessary complexity without improving the quality of the engineering outcome. This creates an important opportunity for organizations to manage CAD data according to its intended use.

CADfix PPS supports this approach by enabling engineering teams to create simplified representations suited to plant and process applications while retaining the original detailed engineering models for activities that require them.

The result is a more practical relationship between model complexity and engineering requirements.

Building More Efficient Food Processing Projects

Food processing manufacturers will continue to face pressure to increase production capacity, modernize infrastructure, and integrate increasingly sophisticated equipment into their facilities.

Meeting those objectives requires effective collaboration between equipment suppliers, engineering firms, contractors, and facility operators. CAD interoperability and model simplification are only part of that larger engineering challenge, but they address a recurring source of unnecessary effort.

The experience of Hawk Engineering demonstrates that preparing equipment models for their intended downstream use can produce measurable improvements in engineering productivity, application performance, and project coordination.

For food processing organizations, the opportunity is to establish these practices before complex supplier models become embedded throughout the facility design process. CADfix PPS provides the capabilities to support that approach, helping engineers translate, simplify, and prepare equipment models for integration into plant and process engineering environments.

As manufacturing facilities become more complex, the ability to manage engineering information efficiently will become increasingly important.

The goal is not simply to create smaller CAD models. It is to ensure that engineering information is appropriate, accessible, and usable wherever the project requires it.
