Off-Site Construction

Off-Site Construction (OSC) is the preferred choice for building owners and construction teams that desire plant systems that are assembled in a controlled factory environment to exacting standards. OSC plants are fully inspected, bench tested and validated at the factory before shipping, which ensures a smooth startup and reduced commissioning times.

Utilizing Epsilon’s custom OSC approach delivers complex systems with limitless configurations and turnkey field installation by Epsilon or a third-party provider.

Why Choose Off-Site Construction?

Our end-user owner and construction company clients choose Epsilon custom off-site construction because of the positive impact on critical project considerations, including:

Project Schedule Pressure

OSC Reduces pressure on project schedules, often removing the M/E systems from the “critical path” by enabling manufacturing efficiencies in parallel with site construction activities.

Rapid Turnover

OSC enables rapid turnover of existing system replacements in situations where the duration and operational risk of shut-downs must be minimized.

Weather Impacts

OSC reduces the impacts of variable and unpredictable weather that is inherent to any project site, by shifting activities to a controlled off-site environment.

Jobsite Safety

OSC improves overall job safety by shifting production hours to a controlled off-site environment with repeatable processes and well-established safety programs.

Transportation and Site Impacts

OSC reduces the transportation logistics and impacts to the project site and surrounding infrastructure, by consolidating deliveries and minimizing laydown requirements.

Workforce Challenges

OSC mitigates the risk of workforce labor cost and availability, particularly in remote locations. This enables projects to accomplish more – in less time – with the trades already on-site.

Seamless Collaboration

OSC provides an integrated multi-disciplinary design team, and collaborates particularly well with design-build and design-assist delivery models.

LEAN Project Delivery

OSC enables any project team to reduce waste across multiple facets of a project – material, labor, schedule, etc. – making it particularly compatible with LEAN construction initiatives and goals.

BIM Technology

OSC leverages the significant advances in Building Information Modeling (BIM) project technologies; all aspects of an OSC project are modeled and optimized as part of the design process.

Off-Site Construction Overview

Traditional Construction Methods utilize a construction manager (CM) or general contractor (GC) who is responsible for coordinating input and output from a variety of resources and sub contractors. There are multiple dependencies, and an issue with any one of the communication channels or deliverables can have a cascading negative impact on the budget and project timeline.

Traditional construction model

Off-Site Construction ensures all the various construction input and output takes place in a controlled environment, under one contract, that is managed for quality assurance and quality control, with continuous feedback and improvement throughout the process.  This results in a single point  of responsibility and accountability for every critical element of the project, from design and fabrication through installation, commissioning and warranty support.
