contractor become lessons learned and become the basis for criteria changes. Several methods or
programs, described below, can assist in the collection of construction data and information for
application to future projects and in the correction of pavement standards, practices or criteria.
a. As-built drawings and design analysis. ER 1110-345-700, "Design Analyses, Drawings
and Specifications" provides policy regarding as-built drawings furnished to the using activity. All
modifications to design joint layouts must be shown on the as-built drawings to insure accurate
information is presented for future pavement removal or replacement requirements, such as for
later installation of utilities. ER 1110-345-700, "Design Analyses, Drawings and Specifications"
requires transmittal of the final design analysis to the using activity upon completion.
b. Pavement construction completion data. Following completion of concrete pavements,
the pavement designer or materials engineer must acquire construction data from the field
construction office and must include this data in a "Pavement Construction Completion Data"
sheet. A sample of the contents of this data sheet is included in Annex 4. This document
summarizes construction information on the pavement, including pavement and concrete data,
aggregate physical tests, gradations and allied data, mixture proportions, and concrete strength
data. This is an essential document, not only for use in evaluating quality of the pavement
product, but more importantly for future pavement service record surveys. Knowing the sources
of materials and other information about pavements constructed earlier enables designers and
materials engineers to assess the long-term durability of aggregates, other materials, and material
combinations, for use on future projects. These documents should be retained permanently in the
district engineering office, and a copy should be sent to the using activity and the TSMCX.
c. Lessons learned report. Following completion of concrete pavements, a lessons learned
office report should be prepared, listing and describing successful and less than successful
construction practices, equipment or materials used by the Contractor. This report should be
retained in the district engineering and construction offices, with a copy forwarded to the
TSMCX. It is understandable why districts are reluctant to describe less than successful
pavement experiences, however, unless these experiences are passed on to USACE elements who
can make necessary changes to criteria or pavement practices, these valuable lessons will continue
to be lost, and the same less than successful practices will likely be repeated on future work.
d. Design criteria changes. ER 1110-345-100, "Design Policy for Military Construction,"
discusses ENG Form 3078, "Recommended Changes to Engineering Documents," for changes to
drawings and specifications, and DA Form 2028, "Recommended Changes to Publications and
Blank Forms," for changes to criteria. These forms should be submitted to HQUSACE (CEMP-
ET), generally by the design or materials engineer, with a copy to the TSMCX, to describe
necessary changes in design standards, guide specifications or other documents or criteria for
concrete pavements.
