Ladder blocking should have been used at the interior wall at exterior wall connection 

Issue

Interior wall at exterior wall connection.

Description of Implementation Error

Six unnecessary studs are used to provide this connection.

Risks

Had Advanced Framing techniques been used an overall savings of approximately $2,000 per building would have been realized. The money could have been available to improve other building components to make them more energy efficient in addition to increasing the builder’s profit margin and improving the marketability of the product.

Required Corrections

A ladder blocking strategy should have been used for the interior and exterior wall connection.
