Modular Building Contractor Insurance

Your work in progress leaves the factory before the building is complete. Property protection needs to account for the module's journey and setting, alongside the plant and site responsibilities you undertake.

The Southern Agency can help you address risks from factory assembly through final site installation.

Industry overview

You may manufacture modules, arrange their delivery, set them on foundations or combine those roles. A finished section must survive loading, the road journey and a crane lift before site connections are complete. Later joint leaks raise a different question from damage to the module during delivery.

The Southern Agency can review your factory, transport, and installation duties to help you select insurance. We can compare protection for modules in transit with liability for site connections and resulting damage after completion.

Risks worth discussing

Transit damage to finished modules

Oversized units moving over the road can be damaged by collisions, road shock, or improper securement.

Setting and crane accidents

Lifting and placing heavy modules onto a foundation introduces dropped-load, rigging, and tip-over hazards at the site.

Factory worker injuries

Assembly-line crews using saws, lifts, and power tools face cuts, falls, and material-handling injuries in the plant.

Water intrusion and tie-in defects

Joints between modules and connections to utilities can leak or fail, leading to water damage and completed-operations claims.

Project property loss during construction

Modules and materials at the jobsite face fire, theft, and weather damage before the building is complete and accepted.

Contract and code compliance disputes

Owners and code officials may allege the delivered building does not meet specifications or applicable building standards.

Situations to think through

These hypothetical examples are not agency claim results. Whether a loss is covered depends on the facts, policy terms, and applicable exclusions.

  1. Hypothetical: Module damaged in transit

    Hypothetical: a transported classroom module is struck and its wall crushed. Transit terms may address covered physical loss if ownership, value, conveyance and stage are included. Identify hauler and loading responsibilities; truck physical damage is not automatically module insurance, and delivery delay is separate.

  2. Hypothetical: Leak at a module joint

    Hypothetical: water enters a module joint months after handoff and damages interior finishes. Liability terms may address covered resulting harm under accepted manufacturing/setting and water terms. Preserve joint tests, acceptance and damage dates; resealing, code correction and output warranties are separate.

  3. Hypothetical: Site fire before completion

    Hypothetical: fire damages set modules awaiting final finishing. Project-property terms may address covered loss if modules, ownership and stage fall within the insured period. Check who arranged coverage and when transit/installation terms ended; a handoff does not itself confirm uninterrupted protection.

Before you talk to an agent

What to have ready

Tick items as you gather them. Nothing here is saved or sent.

Questions to raise

  • Compare actual plant, transit, installation and project-property periods, values and ending events at each handoff. Identify responsibility for a module being stored, loaded, hauled, lifted and connected; adjacent policies do not automatically create continuous protection.
  • Identify actual manufacturer, designer, owner, hauler, and setter, whether roles are combined or subcontracted, and module ownership/acceptance through each handoff.
  • Compare maximum modules per conveyance and staging site with actual plant/storage/transit/unloading/set terms, including hired crane/customer-load and contractor-owned equipment interests.
  • Keep shop inspections and foundation/joint/weather-sealing/utility tests and handoff records. Distinguish later resulting interior damage from module correction, code compliance, and output/delivery warranties.
  • Review actual plant work-in-process/finished stock and machinery values, payroll split, operating interruption interests, and contract/bond obligations, not a blanket plant-to-turnover assurance.

What the agent conversation looks like

Start with the work you do and the questions your current policies leave unanswered. Carrier options depend on your location, risk, and underwriting. Explore our approach.

  1. ListenReview your operations, current coverage, and past claims.
  2. AssessIdentify potential hazards and discuss ways to reduce risk.
  3. BuildDiscuss policy and carrier options, premium costs, and audits.
  4. SupportReview changes and help you plan ahead as your needs develop.

Questions owners ask

Are modules covered while being trucked to the site?

Review actual module ownership/value, carrier responsibility, and insured loading, storage, road transit, and unloading stages, including maximum conveyance/site values. Truck physical damage and cargo/installation terms are different; disclosure alone is not a phase-by-phase coverage confirmation.

Does builders risk apply to modular projects?

Builders risk may help cover the building during site work, though terms must account for off-site fabrication and transit. Coordinate coverage across phases, subject to underwriting.

Who is responsible if a joint leaks after handover?

Preserve actual manufacturing, setting, joint/test, and acceptance records and damage chronology. Review responsibility and resulting interior harm separately from resealing/replacing modules or honoring delivery/code warranties; handover alone does not establish completed-work payment.

Will public projects require bonds?

Read the actual contract and obligee's instrument. Performance and payment bonds address different obligations, subject to terms and surety approval, not unlimited code or output guarantees.

Do I need coverage for my assembly facility?

List actual plant buildings/tools/machines, work-in-process and finished modules and stock, values, and locations. Review property causes, breakdown/income and off-site transitions separately; insuring the factory does not automatically follow each module to acceptance.

How does setting modules with a crane affect coverage?

Identify actual owner, setter, hired crane/operator, and custody/lift-control contracts. Review module property versus riggers liability and owned/hired equipment; stating that you set units does not establish all dropped-load or customer-property cover.

Talk through your modular building contractor coverage

Bring your questions, current policies, and relevant contracts. An agent can review coverage terms, exclusions, and the information carriers ask for, then explain the options available to you.
