specifications, work plans, and submittals. Drilling may commence upon
approval of the anchor installation plan and procedures described in
paragraph SUBMITTALS and after the conduct of the Preparatory Meeting.
1.8
DELIVERY, STORAGE AND HANDLING
Materials shall be suitably wrapped, packaged or covered at the factory or
shop to prevent being affected by dirt, water, oil, grease, and rust.
Materials shall be protected against abrasion or damage during shipment and
handling. Materials stored at the site shall be placed above ground on a
well supported platform and covered with plastic or other approved
material. Materials shall be protected from adjacent construction
operations. Grounding of welding leads to prestressing steel shall not be
permitted. Prestressing steel which is damaged by abrasion, cuts, nicks,
heavy corrosions, pitting, welds or weld spatter shall be rejected and
removed from the site. Tendons shall be inspected prior to insertion into
anchor holes for damage to corrosion protection. Any such damage shall be
repaired in a manner recommended by the tendon manufacturer and approved by
the Contracting Officer.
1.9
SITE CONDITIONS
**************************************************************************
NOTE: Where unique site conditions are anticipated,
as evidenced by drilling performance such as loss of
drill water, the information should be clearly
presented on the drilling logs or otherwise made
known to the contractor. Generally, the plans and
specifications should provide sufficient information
to clearly identify anticipated foundation
conditions. If, based on available information and
site conditions, it is anticipated that additional
foundation exploration will be required by the
contractor, this work should be added to the
specifications.
**************************************************************************
A foundation investigation has been made at the site by the Government and
data is presented on the foundation exploration drawings. [Logs of core
borings] [Subsurface soil data logs] are shown on the drawings. While the
foundation information is representative of subsurface conditions at the
respective locations, local variations in the characteristics of the
subsurface materials may be anticipated. Local variations which may be
encountered include, but are not limited to, classification and thickness
of rock strata, fractures, and other discontinuities in the rock structure,
and variation in the soil classifications. Such variations will not be
considered as differing materially within the purview of the CONTRACT
CLAUSES, paragraph Differing Site Conditions. [Core from the borings
indicated on the drawings] [Additional foundation data] are available for
inspection as specified in the SPECIAL CONTRACT REQUIREMENTS, paragraph
Physical Data. The Contractor is responsible for verifying the location of
all utilities that may be affected by construction or the installation of
the anchors.
