DESIGN, NEGLIGENT OR DEFECTIVE CONSTRUCTION – Fortuitous Act

Fortuitous act – are construction and design defects fortuitous?

For an act or event to be covered under an insurance policy, it must be a “fortuitous” act. An act is fortuitous if it is contingent i.e. unknown to the parties at the inception of the loss. [Chadwick v. FIE (1993) 17 Cal. App. 4th 1112, 1119-1120] See § F44 FORTUITOUS [§ F44:01 In general].

Fortuity questions and issues

Can property damage resulting from a design defect ever be fortuitous? The answer is yes.

Is damage that has been caused before an issuance of the policy damage from a fortuitous act? The answer is probably yes. See discussions § C100 CONTINUOUS OR REPEATED EXPOSURE [§ C100:1.02 Construction defects spanning several policies]; § M14 MANIFESTATION OF DAMAGE [§ M14:4 Pre-existing non-manifesting defect covered]; § P103 PROGRESSIVE PROPERTY LOSS – FIRST PARTY; § S100 SUCCESSIVE LIABILITY POLICIES [§ S110: 2.2 Multiple successive policies; where property damage was “not known” before a policy period].

The above fact patterns can raise interesting coverage questions, but as long as knowledge or information regarding design defects or damage caused before the issuance of the policy are unknown to the insured, the requirement of “fortuity” is satisfied. [Chadwick v. FIE (1993) 17 Cal. App. 4th 1112, 1119-1120] See § C85 CONSTRUCTION DEFECTS [§ C85:9.11].

2. Poor framing practices described in the drawings that were plainly visible from the crawl space in the structure. [Chadwick v. FIE (1993) 17 Cal. App. 4th 1112, 1116]

3. Deficient design and construction of structure floor and frame, including lack of proper contact and connection between structural members; deviations from the framing plans; use of a heavier header than called for and deviation from the flooring plans. [17 Cal. App. 4th 1112, 1115]

4. Negligent welding in a steel supporting system. [17 Cal. App. 4th 1112, 1120]

5. Property damage caused by a “misjudgment in design” causing collapse of part of the structure. [17 Cal. App. 4th 1112, 1120-1121]
