Masonry Evaluation Services
For Repair and Rehabilitation
Preservation and repair of masonry structures requires considerable expertise in all
aspects of masonry evaluation and rehabilitation. NTH provides
architectural and structural engineering services to evaluate and rehabilitate masonry
structures and facades including clay, concrete, stone, and glass, as well as stucco
and EIFS. We investigate and evaluate existing structures, design remedial programs,
and provide contract administration and field observations during restoration projects.
Our masonry experts have provided evaluation services for numerous structures
throughout the United States, many of which have historical significance.
First, NTH reviews construction documents to determine the original design intent. We
then perform a visual condition survey to identify potential problems. Our evaluations
include structural analysis of load-bearing components (where appropriate) and
weather-resistance of facades. We perform non-destructive testing and inspection
openings to ascertain construction details. Our testing methods provide an innovative
enhancement to traditional investigations.
NTH professionals then issue a report that describes existing conditions and the
structural and architectural integrity of the components. We provide rehabilitation
recommendations and include photographic documentation, field measurements and
data to substantiate our observations and engineering assessments.
NTH identifies restoration/rehabilitation alternatives, including cost estimates. The
owner’s plans for future use and the projected service life of the facilities are
incorporated into a present life cycle cost analysis. Our contract documents describe
the necessary restoration work and include technical specifications, details and
drawings, as well as bidding and contractual requirements. We are experienced with
facilitating the bid process.
Field Observation/Contract Administration
NTH provides engineering services during construction to facilitate compliance with
contract documents. Our professionals schedule and lead progress meetings. When
unexpected conditions are uncovered, we resolve the technical as well as
administrative issues promptly. We review submittals and contractor pay requests and
prepare closeout documentation.
