Builders risk protects the project you are building, including materials meant for it, against physical loss until construction ends. The gaps that cost owners money are materials in storage or transit, the existing building in a renovation, and coverage ending when you occupy early.

Liberty Mutual's overview names materials, labor, construction-management fees, temporary structures, and landscaping materials, and says the form controls actual coverage. MMA foregrounds example causes of loss; Liberty Mutual details property categories. Match both descriptions to the values and perils your lender or construction contract requires.

Liberty Mutual lists a proprietary form and a stand-alone Specialty Property offering, but its public overview likewise does not establish the terms for a particular project. You will need a project-specific proposal from either route to compare insurer, form, limits, exclusions, and conditions.
