The masonry nobody sees is the masonry that has to be exactly right. Block walls, footings, and brick piers are laid level, tied in, and grouted to carry the load they are built for, MA code and all.

A specific number for your masonry scope, in writing, that does not move after the site visit.
Laid to last and stood behind. 5 stars on Google says the work holds up.
