In most cases yes.  In our experience, and we design using both systems, the cost of the materials and to prefab and ship the modular components is greater than the cost to have drywall and metal studs delivered and erected.

In general, once on site, the modular wall system installs quicker and without the mess of stickbuilt (drywall metal stud) systems. 

A real bonus if you have a current operation.  It is more flexible in the sense of expanding or rearranging walls again without the standard mess of the stickbuilt system.  Depending on the modular wall panel construction, the quantity of seams can vary widely.  ISO 3 & 4 facilities generally like to have fewer seams as  it makes cleaning easier.  When a modular wall is damaged it is less likely to shed particles, however it can be more difficult to repair.   Additionally, it could be disassembled and relocated, however, there is an additional cost to the disassembly, cleaning, labeling and freight which may reduce the benefit.  

The materials and components of a stick built system can be readily purchased and delivered to a job site.  The installation process can begin when permits are close to being issued.  There is not a lengthy manufacturing-delivery cycle. 

Depending on the plan check-permit issuance duration this may or may not be an advantage. Plan checkers at your city building department will probably be more familiar with metal studs and drywall than a modular wall system.  They may also ask less questions shortening the plancheck process.   

When installed and finished, it can have seamless surfaces and inside/outside corners that are easy to clean and lack the joints and crevices that could hold and release particulates.  Return air paths are easier to create and may take less materials (read: cost) than a modular system.   Metal stud systems usually can accommodate various R values, fire ratings and structural requirements easier than modular systems.

Yes, PETI is willing to handle this aspect of your project.

No, it is not required in most cases. PETI can handle most architectural requirements for the cleanroom facility and if you have requirements for other architectural services, we have Architects that we work with who can provide these services keeping the project as a single point of contact and responsibility.  However, we do not provide architectural services for green field and new buildings.

No, we will do the parts of the project that make sense from you the client’s perspective. 

Give us a call or send us an e-mail.  We will discuss or review your requirements and find out some information about your project.

We will ask questions such as: 

• Is it budgetary for planning or it has been approved for capital expenditure?
• What is the time line for getting a quote?  What is your desired construction timeline?
• What ISO classes do  you require?
• In general, what process will occur in the cleanroom (we will sign an NDA when you are ready to give more detailed information).
• Where is the project site located?
• What electrical power do you have available?
• What are the process heat loads from your equipment?
• What are your other performance requirements e.g. T/RH and +/- tolerances, room pressure monitoring-controls, lighting levels …? 
• What other systems do you need us to look at to support your project such as water (domestic, DI/RO, USP, wifi), drains, exhaust systems, compressed air systems and  process gases?
