A to September — sister companies, one mission. Daniel Marr & Son and Isaac Blair teamed up at First Baptist Church in Newton, shoring, jacking, and preserving the structure for needed façade repairs. Daniel Marr & Son erected the steel shoring tower, which Isaac Blair used to install and operate the hydraulic jacking system, safely transferring structural loads and allowing masonry restoration work below.

Marr’s Shoring Division recently partnered with Soderholm Custom Builders on a chalet located in Manchester-by-the-Sea. To support the upper two levels of the home during the removal of the basement’s load-bearing walls, our in-house engineer designed a ledger system that bolted onto the existing studs on the main level. The system safely transferred the loads to the shoring in the basement, with additional blocking installed where loads fell between first-level joists. This was a great effort by all involved.
