Contractor: Structure -Con, PO Box 2626, Okeechobee, FL 34973
Atrium II Condominium Association requested the services of Mathers Engineering Corporation for
special inspection services for concrete renovation work on the above -referenced building. William
J. Mathers, P.E., S.I. #155, will certify all structural inspections. Under Florida Statute
553.79(5)(d), "the licensed registered engineer service as the special inspector shall be permitted to
send his duly authorized representative to the job site to perform the necessary inspections provided
al written reports are prepared by and bear the seal of the special inspector and are submitted to the
enforcement agency." In addition to William J. Mathers, individuals employed by Mathers
Engineering Corporation are authorized and qualified representatives to perform inspections to
perform the duties assigned by the Special Inspector.
a
We will follow the threshold inspection plan prepared by the Engineer of Record, Keystone p C
Structural Engineering and Consulting, for this project in performing our inspections. Inspections Z } U
for concrete restoration projects follow the general pattern of pre -demolition inspection, progress Z M .a)
inspections until area to be restored has been properly prepared (steel coatings, steel additions and as �
cathotic protection) prior to concrete replacement. Reports of work progress will be generated on P J
monthly basis, signed and sealed by the professional engineer, and sent to the St. Lucie County
Building Department.
Enclosed is a copy of the structural threshold license for William J. Mathers, P.E. as the threshold
inspector for the project referenced above in accordance with Florida Statutes 553.79.

A. PREFACE: It is not intended that the Contractor's contractual and state
any way relieved or foregone by the presence of the Special Inspector. The Contractor has the
sole responsibility for any deviations from the Contract Documents. The Special Inspector does
not replace the duties or the quality control personnel of the Contractor. The Special Inspector
shall not have control or charge of, and shall not be responsible for, construction means,
methods, techniques, sequences or procedures, or safety precautions.
B. OBLIGATIONS OF THE SPECIAL INSPECTOR: The Special Inspector is responsible to both the
owner and the governmental agency having jurisdiction over the project for observing that the
work is executed in accordance with the Contract Documents. It is the obligation of the Special
Inspector to notify the Contractor, governmental agency having jurisdiction over the project,
Architect/Engineer of Record, and the Owner of the following:
1. The use of materials, equipment, and/or workmanship that do not conform to the Contract
Documents or that will cause improper construction.
2. Any work which is not being performed by the Contractor in accordance with the approved
Contract Documents.
3. The recommended removal or repair of faulty construction, or of construction performed
without inspection and not capable of being inspected or tested in -place.
4. The request for interpretations from the Architect/Engineer of Record.
C. REPORTING INFORMATION AND OBSERVATIONS: The Special Inspector's reports are a follow-
up to actual observations during construction; however, they are of extreme importance in that
they enable the governmental agency having jurisdiction over the project, the Owner and the
Architect/Engineer of Record to keep current with the work, while it is in -progress and will be of
value in case of changes in the structure or its use in the future. The report shall consist of one
or all of the following entities:
1. Record of progress.
2. Observations given to the Contractor.
3. Deviations from the Contract Documents with reasons and problems encountered, with
recommendations for the Contractor to initiate proposed solutions or requests for
information from the Architect/Engineer.
4. Log of area inspected.
5. Special Records (foundation preparation and concrete tests) from the testing agency.
6. Record of placing concrete. PY
7. Reports of Engineering Testing Laboratory inspe ins, alu tiocd t
8. Pertinent photographs, where needed. [�
`" ///
Pagel 0 4�
The Special Inspector shall keep a log, with the reports to the Owner based on the above items. Reports
shall be filed under seal to the Building Department.
D. REQUIRED INSPECTIONS
