RFI - Downsizing of Bored
Re: Steel Casing Diameter cc:
[] Urgent [] For Review [] Please Comment [] Please Reply [] As Requested
-Comments:
The City does not agree with their one-third share ($4,473.33) of the total savings on
the downsizing of the 36-and 48-inch diameter bored steel casings. The City wants
their share to be one-half of the total savings ($6710.00) or the diameters of the
bored steel casings can remain at 36-and 48-inches. We need an answer from S.J.
Louis as soon as possible since they want to start boring today. Your consideration
of this matter is appreciated.

S.J. Louis Construction of Texas proposes one "no cost" change alternative on the above referenced proj'ect:
· Conversion of three locations to horizontal directional drilling (HDD). In order to minimize traffic
~md surface disruption and increase the speed at which the project can be completed, ova' company
requests three deep excavation areas be converted to HDD using HDPE (per project specifications): 1)
STA 7'-,-00 to STA 11+50 (450 LF), 2) STA 21+20 ',o STA 26+00 (480LF), a~d 3) STA 32+00 to STA
35+50 (250 LF). Again, this would be a "no cost" change, as S.J Louis Construction would have to
compensate the driller for some areas which would previously had been installed by open cut methods,
amd open cut instalIation at shallow depth is much less expensive than HDD methods. Payment would
be made tiu-ough pay estimate as if ductile iron pipe materials and casing had been installed without any
changes.
S.I. Louis Construction of'Texas proposes one "credit to Owner" change alternative:
· Downsi~ing of bored steel casing diameter. In order to reduce spoil material production and potentially
use smaller bonng equipment, which would reduce traffic and surface disruption and increase the speed
at which the project can be completed, our company requests 330 L F of 36" diameter steel casing be
downsized to 30" in diameter for the 20" DIP (95 LF of 36" diameter casing for 24" gravity SS PVC
remains unchanged), and 88 LF of 48" diameter steel casing be downsized to 42" in diameter for the
30" DIP. The 30" dian~eter steel casing would still allow 4.7" of clear space from edge of pipe bell to
inside wall of casing, while the 42" diameter steel casing would still allow 6.0" of clear space from edge
of pipe bell to inside wall of casing. S.J. Louis Construction of Texas assumes all responsibilky for
ensuring that the pipe can be installed adequately inside the casing, and is completely confident there
will be no problems. Credit to Owner: Total savings of 330 LF x S30 00/LF and 88 LF x $40.00/LF
equals $ l 3,420.00, to be split in thirds for value engineering with Owner receiving $4,473.33 credit,
subcontractor retaining $4,473.33 savings, and S.J. Louis receiving 54,473.33 savings.
