Crushed Granite Sole Source

Added: May 01, 2014 3:52 pm Modified: May 13, 2014 11:27 amTrack Changes This contract action was accomplished using other than competitive procedures because there is only one responsible source due to a unique capability provided, and no other supplies or services will satisfy agency requirements (FAR 6.302-1). See posted J&A for further information.

The U.S. Army Corps of Engineers, ERDC Contracting Office intends to solicit
and award on a sole source basis under the authority of FAR 13.106 to B & B
Trucking Co Inc of Leesville, LA. The Impact and Explosion Effects Branch
(IEEB), Geotechnical and Structures Laboratory (GSL), is conducting
research for the United States Bureau of Reclamation (USBR) to quantify the
response of embankment dams to explosive loading scenarios. As part of this
effort, the USBR has tasked the IEEB with conducting a series of experiments
to revise the Risk Evaluation computer program the USBR uses to evaluate at
-risk dams in their inventory. The experiments require the construction of
scale sections of the upper portion of a zoned embankment dam. The data
generated from these experiments will be used to replace erroneous data
currently used by the software. It is important that the materials used to
construct the dam sections match the materials used to generate the original
data points, thereby allowing the new data points to be directly compared to,
replaced and, where applicable, used in conjunction with the prior data. The
USBR needs to repopulate its risk evaluation software with blast load effects
from a certain set of past blast load data. The USBR chose a class II base
available from B&B Trucking as being the rock material that is closest to the
shell material from their original blast data.
