What is Modular Construction?

Modular Construction is a resource-efficient, off-site delivery method to construct code-compliant buildings in a quality-controlled factory setting.

Prefabricated buildings, prefab, factory-built, modular buildings: All these words refer to the same process of manufacturing a building off-site and installing it on-site. The prefabricated construction process offers design and planning flexibility: it can be either temporary or permanent, small or large, contemporary or traditional, single-story or multi-story, an individual building, or multiple buildings arranged in a complex or campus. Modular construction creates a high-quality building project, built to all applicable codes in far less time than traditional site-built construction, with ‘green’ consideration in terms of sustainable building materials, labor efficiency, reduced waste, reduced site disruption, and reduced transportation emissions.

SKC COMPANY modular construction process consists of 7 steps from concept to completion: Design, Engineering, DSA  Approval, Site Development, Plant Fabrication, Transportation, and Installation. More detailed descriptions of each step are featured in the following step by step explanation.

STEP 1 – Design

The design phase of the modular building process creates a description of the building, usually represented by detailed plans and specifications.

A thorough customer consultation with our Design, Project Manager, Estimating and Sales team to gather the information required to develop the building plan. Some of the building parameter questions include:

  • What is the project budget?
  • Has land been acquired?
  • Is the building intended for temporary or permanent occupation?
  • How soon will the building be occupied?
  • How many people will the structure house?
  • How much square footage is required?
  • How many modules will be required?
  • How many bathrooms are required?
  • Are fire suppression systems required?
  • Does the building need to be Fire Rated?
  • Does site have special wind speed zone?
  • What direction will the building face?
  • What exterior finish does the customer want?
  • What interior finish does the customer want?
  • What flooring does the customer want?
  • What kind of foundation is appropriate?
  • What kind of roof is appropriate?

This is where we identify what the customer is looking for whether it’s a cost-driven utilitarian building or a modern energy efficient modular building. Once this information has been gathered SKC COMPANY design team will produce the ideal modular building design to fit the customer’s needs.

Step 2 – Engineering

Each building design goes through the SKC COMPANY engineering department for an engineering review. Like site-built structures, modular buildings are subject to a series of national, state and local building codes that ensure the building meets a set of standards for safety and performance. State-level building codes can be superseded or augmented by local building code requirements, such as the High-Speed Wind Zone code adopted by many coastal counties. During the building review process, the SKC COMPANY engineering department confirms the design proposal meets all applicable building codes. For example, in the State of California all industrialized modular components are required to comply with the following codes:

2016 California Administrative Code, Part 1, Title 24 C.C.R.
2016 California Building Code (CBC), Part 2, Title 24 C.C.R.

Step 3 – DSA APPROVAL

The building owner is ultimately responsible for securing building permits, paying DSA fees for work on their property. In practice, most building owners appoint the general contractor as an authorized representative so the contractor can obtain the required permits. The building owner is advised to confirm that the general contractor has secured the proper building permits for their project. Failure to obtain the proper permits can result in significant fines, penalties, and even removal of unauthorized construction.

STEP 4 – Site Development

One of the advantages inherent in modular construction is that the site development and building foundation are prepared while the modules are being fabricated at the manufacturing facility and transported to the job site.  The site development and building construction processes happen concurrently instead of sequentially like site-built construction.  Projects are developed in a variety of geographic settings typical site development includes:

  • Surveying
  • Demolition
  • Excavation
  • Grading
  • Site drainage
  • Foundation construction
  • Utility installation

There are two primary modular building foundation classifications; on grade and raised concrete or wood foundation.  An on-grade foundation is generally for permanent installations and is more expensive. A wood foundation can be used for temporary or permanent structures, it is less expensive to install, and it is more cost effective to relocate the building later while causing minimal site disturbance.

STEP 5 – Modular Fabrication

All of our modular buildings start with a welded steel frame forged in SKC COMPANY steel shop.  The steel frame is then loaded on the main factory production line where the sub-floor is insulated and floor decking is assembled atop the steel frame.

As the module moves down the production line framed wall sections are fabricated, insulated and hoisted in place. The steel truss roof assembly is built in components at ground level before it is hoisted into place.  The module proceeds down the line where mechanical, electrical and plumbing services are installed while the last of the insulation goes into place. Interior finishes like drywall, painting, and flooring are applied while doors and windows are installed.

On the last stop of the production line, the exterior finish and trim are applied before the module is prepared for transportation.

During construction at the manufacturing facility a third party inspection agency is present to ensure the modules are built in compliance with building code.

STEP 6 – Modular Transportation

The fabricated modules are shipped over the road by carriers that specialize in modular building transportation.  In most U.S. jurisdictions building shipping limitations are 16’ in width and between 70’ & 90’ in length per module.  SKC Standards 12’width by 40’length.

The scope of the project and the size of the modules determines how the project is transported to the job site.  For large projects, like a man camp, that consist of dozens of modules the delivery is staged in phases so that our PM or Vendor can prepare coordination and install the modules in a logical sequence.

STEP 7 – Modular Installation

A general contractor, often one specializing in modular construction, will install the modules, complete any on-site finish out and make the final utility connections.

The choice of building foundation determines how the building will be installed. Permanent, semi-permanent and on grade foundations will require the modules to be set with a crane.  Raised wood foundations, typically used for temporary buildings, allow the modules to be set in place through simple mechanical methods.

With the modules in place final finish out of the interior and exterior proceeds.  Finish out can include electrical and mechanical system connection between modules, stairs, wheelchair ramps, skirting, exterior siding, trim and utility connections.
