Design, Installation and Commissioning of Industrial and Commercial Plants

Mongrel Investments adds value to your industrial plant design project by combining plant and unit operation knowledge, with experience in a wide variety of industries and applications. Combining our experience in industrial plant design with your intimate knowledge of your process, our plant design engineers develop a solution that meets your budget and timeline.

Our engineering and fabrication expertise is coupled with a unique modular approach. From equipment selection to construction management, coordinating the entire scope of the project is a complex process in which we excel. From piping specifications on every P&ID to managing subcontractors, we ensure every detail meets or exceeds your needs.

Mongrel Investments’ modular design approach saves an average of 24% time compared to traditional construction schedules. Your plant will make product sooner, and overall costs will be reduced. We generally follow a 5 step process as follows:

STEP 1: Front-end Engineering for Industrial Plant Design


Our plant design engineers will fully extract the project scope, discuss potential challenges, and create a comprehensive project schedule up-front. This is a critical first step in developing your plant.


Most companies provide a basic quotation that doesn’t ensure project success. Mongrel Investments believes engineering detail is most important in the beginning of the project. We spend essential time up-front to provide accurate preliminary pricing and a design you can be confident with.

We leave it to you to decide how precise you want your number to be.


STEP 2: Detailed Design

The first part of detailed design includes a tightening of the numbers and scope of your project. One fixed bid price has been reached, the following begins:

  • Re-evaluation for further time/cost savings
  • Set key project milestones and dates
  • Finalize modular industrial plant design including:
  • Process automation
    • Mechanical and structural design
    • PFD’s
    • P&ID’s
    • Footing details
    • Shipment constraint planning
    • 2D and 3D models
    • CAD system development
    • Any process modeling that must be completed (ex. ASPEN HYSYS)
    • Additional drawing development
    • Auxiliary views
    • Detailed elevation drawings
    • Detailed plan drawings
    • General equipment and arrangement drawings
    • Isometric drawings



STEP 3: Equipment Procurement for Industrial Plant Design


Once our plant design engineers complete detailed engineering, we order equipment for your project. Equipment with long lead times, or key to project milestones, is ordered first. Equipment is selected upon lowest total lifetime cost, as opposed to lowest upfront cost.

SIDE-STEP: Process Safety & Health Studies


If your process requires any safety study, they will be completed during design. The timing depends on your availability and the information needed to complete the design.

Step 4: Industrial Plant Construction

A compressed build timeline, higher quality construction and lower total modular fabrication costs are direct outcomes of the controlled, production-style environment. Parallel field upgrades happen simultaneously to industrial plant construction without interfering with each other, since plants are constructed in our shop as modules while site-upgrades happen at your manufacturing facility. We employ skilled craftsmen that have honed exceptional skills in electrical wiring, welding, pipe-fitting, and equipment assembly.

Step 5: Installation and Commissioning

Once off-site  industrial plant construction is complete, modules are fully FAT tested and then shipped to your site for installation. Mongrel Investments’ process experts install your new production plant and make sure it is fully integrated, both mechanically and electrically, into your facility. Process hookups, functional testing and the punch-list are completed and resolved. We fully train your plant operators on the full system, and we provide continuing support for any questions or concerns you may have going forward.
