Talking About the Neighbors

by Don Friedman on March 26, 2015

And I don’t mean gossip.

We’ve had a large number of projects in the last few years where we review the effect of construction on neighboring buildings.

In either case the goal is the same: to minimize damage to the existing building from the effects of construction.

It turns out that this is a popular topic. I’ve been asked by the Society for Clinton Hill to talk about some of the technical issues involved and give advice to building owners, particularly people who own brownstones. I won’t be discussing our projects, but I will be reviewing what we’ve learned from working on those projects.
