LIMITATIONS
As our client, please recognize that construction monitoring is a technique employed to reduce
the risk of deviations from the approved plans from becoming incorporated into the completed
project without appropriate engineering review and approval. Provision of construction
monitoring by D&M/Terratech's field personnel is not insurance, nor does it guarantee
construction of any type. Even with diligent monitoring, some construction defects may be
missed. In all cases, the contractor shall retain sole responsibility for the quality of work, for
adhering to plans and specifications and for repairing defects, deficiencies or omissions,
regardless of when they are found. We have performed our services in a manner consistent with
the standard of care and skill ordinarily exercised by firms of our type practicing under similar
conditions at this same time and locality. However, we do not undertake the guarantee of
construction or production of a completed project conforming to the project plans and
specifications. No warranty is expressed or implied. Our services during the identified time
period were limited to those documented in our attached report.
We appreciate the opportunity to work with you on this project. If you have any questions
concerning our observations or test results, or require additional information, please do not
hesitate to contact us at your earliest convenience.
Sincerely,
