In-House Fabrication Shops

From design to production to installation. Once system designs are finalized, our in-house sheet metal, plumbing, and piping shops act. They fabricate, assemble, and meticulously package our products, ensuring safe delivery and hassle-free installation. Coordinating with our in-house shops and subcontractors guarantees a smooth and efficient process. We operate a total of 40,000 sq ft of in-house fabrication facilities.

We can quickly turn around products—even with custom specifications—and adjust our inventory on the spot. Changes? No problem and no delays.

So whether you’re embarking on a new construction project or seeking to upgrade an existing system, we are ready to bring our expertise and execution.

Certification Milestone for our Fabrication Shop SAVES TIME and MONEY for our customers.

Investing in our capabilities for our customers’ confidence. We are proud to announce that Holaday-Parks has completed a rigorous certification process resulting in both UPC (Uniform Plumbing Code) approval through IAPMO R&T and NSF-61 (National Sanitation Foundation) certification for our shop-fabricated stainless steel welded assemblies.

Holaday-Parks is the ONLY area fabrication shop to meet Public Health & Seattle/King County’s stringent requirements for shop-fabricated assemblies installed within potable domestic water piping systems. (Read the King Co. article HERE)

We know how important it is for projects to stay on budget, and this certification is another way we demonstrate our dedication to that. Other area contractors must purchase fittings from an outside source at a much higher cost and could be susceptible to price fluctuations and availability concerns. With our in-house capabilities, these concerns are eliminated. Read more about the importance of this certification in our Blog HERE.

Comprehensive MEP Service & Preventative Maintenance

Emergency Response that Owners and Operators Rely on. Regardless of how optimal a Preventative Maintenance Plan may be—when dealing with mechanical, electrical, and plumbing—things happen, and usually not at a good time. Critical or emergency failures require an efficient and fast resolution. With 24/7 Emergency Response, Holaday-Parks has qualified technicians dedicated to helping you be the hero.

We recognize that building occupants may not always be aware of the meticulous management behind the scenes to keep operational systems running smoothly—until something goes wrong. So in addition to emergency mechanical, plumbing, and electrical service, our Preventative Maintenance Plan can help avoid those headaches in a more cost effective, and predictable way.

Key Benefits to Reduce Operational Costs and Stress:

  • Optimized Performance: Ensure your building operates at top performance levels.

  • Comfort and Safety: Prioritize occupants’ well-being with a proactive maintenance approach.

  • Cost Savings: Address potential issues before they become costly, saving you time and money.

How Holaday-Parks Helps You:

Our team specializes in developing customized Preventative Maintenance Plans tailored to your needs. By partnering with us, you’ll benefit from proactive maintenance strategies to prevent issues before they impact your operations.

Don’t wait until something goes wrong. Let us work with you to implement a preventative maintenance plan that keeps your building running seamlessly.

Mechanical Engineering

Unmatched engineering expertise leads to cost-effective innovations. Our in-house Engineers, CAD Professionals, and Detailers are involved in the early stages of Preconstruction and Design. The Holaday-Parks’ approach includes:

  • Assessing the site building systems and building technologies

  • Determining critical environments

  • Analyzing energy cost savings

  • Presenting value-engineering options

Our teams utilize the latest versions of construction software and tools (including: Bluebeam Studio, AutoCAD, Navisworks, Revit, and Trimble). We coordinate with other subcontractors to determine a fully coordinated Building Information Model (BIM) which:

  • Minimizes overlapping efforts

  • Simplifies routes to ensure fewer connections (minimizing leak potential)

  • Identifies any issues within existing structures

Contact us and let us talk about your next project.


Energy Services

Energy sustainability is what we do, and the first step is benchmarking what you currently have. We can determine how your building performs, identify energy-saving opportunities, provide a cost analysis for optimization, and monitor energy performance. We monitor performance through check-ins and system alerts after you know how your building measures up— we’re here to help you reduce your energy costs and overall energy consumption.

WA State Clean Buildings Standard (HB-1257)

Navigating through government standards, policies, and compliance measures can be complicated— we can help. Learn more about HB-1257 and how Washington State commercial building owners prepare to meet fast-approaching compliance deadlines.

Building Commissioning

From top to bottom—we will make sure your building is working as intended. We provide a documented verification process through our Building Commissioning service that ensures the building’s performance for new construction and existing buildings. We commission all building sizes and types from office to education to healthcare to industrial. Our goal is to equip our customers with a fully functional building on day one of occupancy.
