The provisions of ASTM D 1143, such as pile set-up
time after driving, test load, method of applying
load, loading and unloading procedures,
instrumentation, etc., should be carefully examined
and modified as necessary to fit the specific load
test being conducted.
**************************************************************************
Load tests shall be in accordance with ASTM D 1143, [_____] loading method.
The load tests at locations shown or directed shall be made on test piles
placed to the tip elevation used for establishing lengths of piles for
bidding, except as otherwise directed by the Contracting Officer. Loading,
testing, and recording of data shall be under the direct supervision of a
registered professional engineer. A report shall be submitted in
accordance with paragraph SUBMITTALS. The installation of contract piles
shall not proceed in a new area with substantially different subsurface
conditions until a satisfactory load test has been performed in that area
and the results approved by the Contracting Officer. A minimum of [14]
[_____] days from submission of the report shall be allowed for approval.
3.2.3
Safe Design Capacity
Test piles shall be loaded to twice the anticipated working load unless
failure occurs first. The safe design capacity of a load test as
determined from the results of load tests shall be the lesser of the two
values computed according to the following:
a.
One-half the load that causes a net settlement after rebound of
not more than 0.029 mm per kN 0.0l inch per ton of total test load.
b.
One-half the load that causes a gross settlement of not more than
25 mm 1 inch provided the load settlement curve shows no sign of
failure.
3.3
SPECIAL INSPECTION AND TESTING FOR SEISMIC-RESISTING SYSTEMS
**************************************************************************
NOTE: Include this paragraph only when special
inspection and testing for seismic-resisting systems
is required by paragraph 3.2 of FEMA 302, NEHRP
RECOMMENDED PROVISIONS FOR SEISMIC REGULATIONS FOR
NEW BUILDINGS AND OTHER STRUCTURES.
This paragraph will be applicable to both new
buildings designed according to TI 809-04, SEISMIC
DESIGN FOR BUILDINGS, and to existing building
seismic rehabilitation designs done according to TI
809-05, SEISMIC EVALUATION AND REHABILITATION FOR
BUILDINGS.
The designer must indicate on the drawings all
locations and all features for which special
inspection and testing is required in accordance
with Chapter 3 of FEMA 302. This includes
indicating the locations of all structural
components and connections requiring inspection.
Add any additional requirements as necessary.
