Assembling the majority of the structure in a controlled environment means:<\/p>\n

- Less downtime for laborers since weather delays and damaged materials are not an issue<\/li>\n
- Quicker assembly as each contractor can work on individual modules in a rotation format<\/li>\n
- Minimal disruption for local residents and communities because of faster on-site assembly<\/li>\n<\/ul>\n
These advantages are appealing, but keep in mind that you can only reap these benefits if you plan for off-site construction from the beginning \u2014 not as an afterthought.<\/span><\/p>\n
<\/span><\/p>\n
When and How to Plan Your Off-site Build<\/h3>\n
When a developer or architectural team is putting a project together, it should be clear how \u2014 and to what extent \u2014 the project will be completed using an off-site solution.<\/span><\/p>\n
Off-site builds (particularly those featuring modular or panelized methods) are still unfamiliar to most of the traditional construction world, meaning more time is needed on the front end to plan, prepare, and familiarize teams with the unique process.<\/span><\/p>\n
Here’s an example:<\/span><\/p>\n
When a stick-built, single-family house is being built, raw materials are delivered to the job site on a schedule. It usually goes something like: steel, framing, and truss components first, followed by windows and doors, electrical and plumbing components, exterior finishes, etc.<\/span><\/p>\n
For most contractors this schedule never changes, and the process runs \u2014 for the most part \u2014 like a well-oiled machine.<\/span><\/p>\n
With an off-site build, however, the construction schedule is accelerated thanks to fewer deliveries and steps to assembly. But this benefit can only be realized if approvals, phasing, and sequencing are well planned and rehearsed.<\/span><\/p>\n
Everyone, from the contractors to the local building-approval office to the delivery teams, needs to understand the new schedule and phasing for the project to run smoothly.<\/span><\/p>\n
“A fundamental barrier to off-site construction is this idea of timing, planning, attention to detail, really looking over the drawings and making sure they’re set so people can make that robotic equipment and routers and all of that, to deliver [the materials] to you on the job site,” said Jack Armstrong, director of SIPA (Structural Insulated Panel Association), in a recent article by the National Association of Homebuilders (NAHB).<\/span><\/p>\n
Depending on the size and scope of your job, an off-site build typically takes between 6 and 12 weeks of lead time, compared to the 1 to 4 weeks required for stick-built projects. From the moment you break ground, many of the processes are different, so plan accordingly and plan ahead.<\/span><\/p>\n
<\/span><\/p>\n
4 Elements of Sequencing Success<\/h3>\n
To establish precise timing from the get-go, off-site project schedules should work on a strict (yet realistic) timeline, dependent on four important factors:<\/span><\/p>\n

- Change Orders<\/span><\/strong>
In prefab and modular construction, decisions must be made earlier and the footprint of the structure must stay fixed for turnaround times to be fast and efficient. The good news: Off-site projects typically have fewer change orders compared to traditional construction, thanks to accurate modeling technology and the nature of repetitive construction methods.<\/span><\/li>\n- Scheduling<\/span><\/strong>
When your team understands the parameters of off-site construction, prefab and modular construction timing can be extremely predictable. To keep design approvals, phasing, and sequencing on the fast track, the modular builder will often produce a “big picture” schedule that details how each task is integrated. This important step ensures that site development, in-factory assembly, and on-site construction are timed perfectly.<\/span><\/li>\n- Scope of Work
<\/span><\/strong>The scope of work defines who is in charge of completing each step of the project, which creates a cooperative, coordinated team effort from the start. Unlike some traditional projects, each off-site project needs to be tailored to suit the team’s agreed-upon approach, roles, and responsibilities \u2014 specifically between the modular builder and the general contractor. There are three options for the modular builder’s role:\n - Scheduling<\/span><\/strong>
