AccelDeck™
Elevated Chiller Support System
AccelDeck™ Advantages
- Elevated support for chillers, tanks, and related cooling equipment above the building.
- Long clear spans and heavy equipment support for large cooling loads.
- Integrated accommodation for hanging-loads and pre-installed embeds for equipment attachment, screens, and guardrails.
- Factory-installed grating with clearly defined maintenance access paths.
- Improved coordination of routing, equipment zones, and platform service areas.
- Repeatable modules that support faster installation and more predictable delivery.

Supporting Next-Generation Data Centers
Customizable Grids: Beam profile and spacing accommodates most chiller models giving the owner flexibility to procure different chillers late in the manufacturing phase, even allowing for future replacements without modifying the underlying support.
Load Capacity: Standard Configuration supports chiller, tanks and other equipment with weights up to 40,000 lbs. Design can be customized to accommodate more challenging equipment configurations.
Integration: Fully compatible with Clark Pacific’s structural system, ensuring durability, longevity, and seamless integration with the overall project.
Elevated Mechanical Platform vs. At-Grade Mechanical Yard
AccelDeck™ moves chillers and primary distribution above the data center, keeping grade-level circulation, walls, and site perimeter clean. The prefabricated platform organizes routing, access, embeds, and equipment support into one repeatable system for faster, more predictable installation.
Traditional at-grade chiller yards consume valuable site area and crowd the perimeter with exposed equipment, piping, headers, and field-built steel. These systems increase trade coordination, constrain access and laydown, and reduce flexibility for generators, electrical yards, and future expansion.
AccelDeck™
Prefabricated Chiller Support System, Accelerates Construction Schedules an Additional 4-8 Weeks.
Engineered to replace traditional structural steel framing systems, the platform offers an efficient, single-source solution.
Embedded Strut-Channel Inserts:
Simplifies pipe and equipment installations, creating flexible attachment points for hanging MEP and IT loads without field drilling.
Easy Installation and Maintenance: Six foot plus heights, provide easy access for maintenance and future equipment upgrades.
Moveable Grates: Improve maintenance access in completed data centers.
Integrated Hardware for Hanging Loads: Plant installed, embedded strut-channel inserts support chilled-water piping and related mechanical equipment.
Accelerated Construction: Incorporating AccelDeck™ into a prefabricated precast data center can reduce project timelines by months.
Frequently Asked Questions - Clark Acceldeck™
Can Clark Pacific deliver rooftop mechanical platforms for the support of chiller yards over the data center?
Yes. Clark Pacific has developed prefabricated rooftop mechanical platform as a part of its standard “kit of parts”. This platform is coordinated with the building’s structural grid and is supported by the same columns that support the floor and roof framing below.
Can Clark AccelDeck™ support long spans and heavy mechanical loads?
Clark AccelDeck™ can be configured for 60-plus-foot clear spans for heavy mechanical loads when project geometry and loading criteria support it. Aligning spans and loading requirements early helps keep equipment zones open and can reduce the need for field-added secondary framing.
How are embeds, penetrations, and tolerances controlled in Clark AccelDeck™?
Embed and penetration locations, sizes, tolerances, and load ratings are set and approved during shop-drawing coordination before fabrication. This upfront definition gives the project team a higher-confidence installation package and reduces clashes in the field.
How does Clark AccelDeck™ support future Day-2 expansion?
Clark AccelDeck can be planned with modular Day-1 and Day-2 penetrations and landing zones so future mechanical and electrical capacity can be added with less demolition or redesign. That makes future phases more deliberate and helps preserve schedule and constructability when additional infrastructure is needed.
What factory-installed features can be built into Clark AccelDeck™?
Depending on project scope, Clark AccelDeck™ can incorporate factory-mounted embeds and plates for chillers, racks, AHUs, and power equipment; factory-cast raceway sleeves, conduit stub-ups, and cable-tray supports; plant-installed galvanized grating; and pre-installed embeds for guardrails, screens, and equipment attachment. Bringing these items into the plant reduces field layout and fit-up risk.
Can rooftop mechanical systems be integrated into Clark AccelDeck™?
Yes. Rooftop mechanical systems and platforms can be designed to tie directly into the precast structural grid, so equipment supports, distribution zones, and perimeter support conditions are coordinated early in design.
