SECTION SIX
Final Inspections and Certifications
INSPECTIONS
The project utilized the U.S. Army Corps of Engineers (USACE) Three Phase Inspection
Program which included the Preparatory Inspection prior to the start of work, Initial Inspection
as soon as representative portion of the work was complete, and Follow Up Inspection daily
until the work is complete. Prior to site mobilization a list of the Definable Features of Work
was generated. The Definable Features of Work list was a guideline for initiating the Three
Phase Inspection Program on individual work tasks. The Definable Features of Work list was
updated monthly and forwarded to the USACE for information only.
CERTIFICATIONS
As part of the submittal process data, drawings, instructions, schedules, statements, reports,
certificates, samples, and records were transmitted to the USACE for either review and action or
for information only. Each individual submittal was given a unique transmittal number.
Submittals were forwarded to the USACE on Government Form SF4025 and to other reviewers
such as the USACE Architectural Engineer, USEPA, and TNRCC on Government Form
SF4026. Submittals were tracked in the Complete Submittal Register that was updated on a
monthly basis. A copy of all submittals was kept on file at the project site.
The Quality Control Department was responsible for generating a Daily Contractors Quality
Control Report (DCQCR). Starting with mobilization, through the contract completion date, a
DCQCR was generated and issued for each contract day. The report included the following
information: date, report number corresponding to the number of contract days, general weather
information, work performed by H&S Consultants, attachment reports, work performed by
subcontractors, inspections performed, testing performed, verbal instructions received from
Government personnel, verbal instructions received from Government personnel on construction
deficiencies, safety violations observed, remarks, and worker hours and equipment use. Two
copies of the report (one with the original H&S Consultants QC signature) were forwarded to the
USACE QA Field Office.
Data Quality Objectives (DQOs) were established prior to the start of the project and were
updated throughout the project. Individual programs such as the Perimeter Air Sampling
Program and the Chemical Quality Management/Sampling Program defined DQOs. Objectives
included precision, accuracy, representativeness, comparability, and completeness. In 1997, a
process to consolidate the DQOs was performed. The result was a document that defined DQOs
for all chemical data generated on the project. The DQOs were summarized using a seven step
process outlined in EPA's "Guidance for the Data Quality Objectives Process" (1994).
HEALTH AND SAFETY
A Permea-Tec pad was used to verify that beta-napthylamine (BNA) had not permeated gloves
and protective clothing during usage. To use this method as a field verification of chemical
protective gloves, a worker wore a pad on the back of the hand over the top of the inner glove
and beneath the outer glove for approximately two hours. After wear, the outer glove was
