Feasability Studies

Feasability Studies

We evaluate the benefits of our prefabricated structures as they relate to overall space needs in both the short and long term. Modular structures work with virtually any budget. Re-usability, flexible engineering capabilities requirements, and the vast number of ideas for maximizing space usage combine to make modular buildings one of the most cost-effective and efficient elements in the construction industry.

Our Professional Design Services Contract gives customers a comprehensive study of their project. It includes assistance with the design and engineering of a modular structure that meets the customer needs while maximizing the efficiencies and cost effectiveness of modular construction.

We will:

  • Provide electronic conceptual building floor plan design drawings
  • Provide a list of sub-contractors that the Contractor intends to use to complete the design project, including verification of any appropriate certifications and/or licenses that may be required to perform the service
  • Represent the customer's best interest at design review and advisory meetings as mutually agreed on for the term of the contract period
  • Based on comments from design review and advisory meetings, provide revised floor plan, specifications, color elevation view drawings of the proposed exterior, and a code review
  • Provide preliminary, not for construction, design and engineered building and foundation plans, specifications, and final color elevation view documents




Upon completion of a feasibility study, Wilmot's team will consult with our network of suppliers to design the right space to meet our client's specific needs. Our team can recommend interior and exterior floor plans, quality building components, and other materials that work within our client's budget, quality requirements, and timelines.

Wilmot Modular: Building Permit Process

3rd Party Approved Drawings

This is where the difference between the traditional construction process and the modular construction process is seen. On a traditional construction site, a local inspector must be called out during certain phases of the project to inspect the work for state and local code compliance.

In the modular construction process, the drawings are submitted to a 3rd Party Licensing Agency that is responsible for making sure all drawings meet those same state and local codes. As the building proceeds through the factory, it is inspected for compliance to those codes. When the building is delivered to the site, there is no need for additional inspections which may hold up the building process. The building will already be approved and will have state labels affixed to it for proof of compliance.

Wilmot Modular: Building Permit Process

Approval Drawing

Drawings are created showing the proposed building layout with specifications for customer's approval. Production drawings are created based on those approval drawings.

Geotechnical Soil Analysis

A Geotechnical Soil Analysis may be ordered to confirm the soil bearing capacity of the site location of the building. A civil engineer may be hired or a firm that specializes in Geo tech surveys. Generally the owner or owner's rep will either order the survey themselves or have Wilmot coordinate the soil analysis.

A Geotech survey determines the type of soil as well as its strength. It will determine how expansive the soil is under the proposed building. In other words, it will tell you how much the ground will shrink and swell. It's important to know how expansive the soil is under the building. If building on expansive clays, extra deep footings would be required so the building doesn't move, or in extreme cases, fall down. Some soils are dispersive, and when they get wet they erode away very quickly. All important things to know before a foundation can be designed for the building.

Wilmot Modular: Building Permit Process

Structural Foundation Plan

A structural Foundation plan is designed and drawn by a civil engineer. It is designed based on either the geotechnical survey completed for the site or on an assumed soil capacity. It is ordered either by the Owner, Owner's Rep or Wilmot Modular Structures.

The function of a foundation is to provide a level and uniformly distributed support for the structure. The foundation must be strong enough to support and distribute the load of the structure and sufficiently level to prevent the walls from cracking and the doors and windows from sticking. The footing distributes the weight of the structure over a large area. The footing is usually always made from concrete because it can withstand heavy weights and is virtually decay-proof. There are generally two types of foundations: a concrete slab foundation and a raised foundation made from piers and columns and/or perimeter wall.

Wilmot Modular: Building Permit Process

Civil Engineering Plan

A Civil Engineering Plan is created using information from the Structural Foundation Plan and the 3rd Party Approved Drawings. It is created and sealed by a Civil Engineer and is ordered either by the Owner, Owner's Rep or Wilmot Modular Structures. It is also called a Site Plan and includes grading, landscaping and other site details.

Wilmot Modular: Building Permit Process

Submit for Building Permits

Once the Civil Engineering Plan has been completed, a package that includes modular building plans and site utilities engineering is submitted to the Authority Having Jurisdiction (AHJ) by either the Owner, Owners Rep or Wilmot Modular Structures. Generally, there will be questions and clarifications that need to be made and correspondence will go back and forth between the AHJ and the submitting party.

Wilmot Modular: Building Permit Process

Building Permits

A building permit will be issued which authorizes the holder of the permit to erect a building on the location specified in the permit. The permit will be in the name of whoever the team has specified to be responsible for the construction of the building and its compliance to local codes, zoning regulations and requested use.

Generally, construction of the building in the factory and foundations at the job site do not begin until a building permit has been obtained.

Wilmot Modular: Building Permit Process

Utility Permits

Utility Permits are pulled by the electrician hired to hook the building up to the closest utility connection. Once a building permit has been obtained, the electrician will go to the local permitting office and request a utility permit. It is generally a one-day turnaround and simple to obtain.

Wilmot Modular: Building Permit Process

Final Use and Occupancy Permit

Once a building has been completed on the site, a Final use and Occupancy Permit must be obtained prior to moving into the building. The Permit Holder will call for an inspection by the AHJ . Upon inspection and approval of the use of the building, a permit is obtained and the occupant may move into the building.

Wilmot Modular: Building Permit Process

Move In

Once a Final Use and Occupancy Permit has been issued, the building has been certified to be in compliance with applicable building codes and other laws, indicating it to be in a condition suitable for occupancy. It's time to MOVE IN!!!


Site Planning

Site Planning

We serve as general contractor, overseeing all aspects of site preparation using our extensive subcontractor network. With Wilmot providing a total turnkey solution, no detail will slip through the project plan, ensuring timely completion and quality performance. Site work is done at the same time the component modules are being fabricated in the factory. The simultaneous construction and site preparation is where the majority of time savings is realized by our customers.




After the client approves the design and project plan, module fabrication begins. The assembly process is coordinated with simultaneous site preparation in order to benefit work schedules, materials and sub-trades availability, and to ensure that quality standards are met. Sections are transported by Wilmot's licensed and approved carriers to the job site as each module is completed.


Delivery & Installation

Delivery & Installation

Installation of the component modules begins as soon as they arrive to the fully-prepared site. All modules are constructed by our team of sub-contracted experts in strict accordance with the project plan.
