RE. Bethel Road -Addendum #3A
TranSystems Project No 20000890
Dear Mr Gnffin
Please consider this additional fee request for engrneenng services associated with the Bethel
Road Project. The additional engrneenng services include changes to the Box Culvert/Channel
Plans, an Early Box Culvert/Channel Plans Submittal and a 16" Waterline Extension The
additional work is summanzed below
First Changes To Box Culvert/Channel Plans.
Addendum #l, dated March 31, 2003, included the addition of channel improvements between
Freeport and Coppell Road. The channel was to he a concrete line channel as depicted in the
October 1, 2003 and November 14, 2003 plan sets In February of 2004, TranSystems was
instructed to change the concrete line channel to a gabion lined channel to accommodate the
COE permit requirements Changes to the plan set were as follows
• Gabron Channel details (Freeport Headwall, Bethel Boxes & Typical Section)
• Revised channel cross-sections
• Revised the Channel Plan & Profile Sheets
• This effort included running an additional HEC 2 run for gabion walls
• This effort also required prepanng several exhibits for Loretta Mokry at Allen Plummer
which included gabion channel details, channel plan & profile sheets and quantities
information
Second Changes To Box Culvert/Channel Plans.
Following the submittal of the 90°Io Plan Set, dated March 18, 2004, which included a gabion
lined channel, TranSystems was asked to remove the gabrons and the 4-5'x10' box culverts at
Bethel Road. Changes to the plan set included
• Revised plan set to remove the channel plan & profile sheets downstream of Freeport
• Addition of a detail showing how the box culvert openings at the Freeport headwall were
to be covered/blocked so that storm water flow would exit the headwall structure within
the existing channel This also included an additional detail of 2'x2' equalization
openings to allow storm water in the adjoining blocked boxes to get to the open boxes

~~
Third Changes To Box Culvert/Channel Plans
Following the submittal of the Final Review Plan Set, dated November 2004, TranSystems was
asked to put the gabions and the 4-5'x10' box culverts at Bethel Road back into the plan set, but
dust down to Sta. 34+50 This change was made following notice from the COE that stream G-1
from Freeport to Bethel was not jurisdictional, and a permit could soon be acquired for the 4-
5'x10' box culverts at Bethel and the gabron lining for 350 feet past the box culverts Changes to
the plan set included.
• Revised plan set to add the channel plan & profile sheets back
EarlYBox Culvert/Channel Plans.
Following receipt of City comments on the Nov 2004 Final Review Set, dated May 2, 2005,
TranSystems was called to a meeting at the City (July 14, 2005) where they were asked to
prepare an early drainage plan set. The early drainage plan set was to include the box culverts
from Sta. 19+00 to the headwall at Freeport, plus the gabion lined channel down to Sta. 29+00
(later revised to Sta. 26+00) The effort put forth for the early drainage plan set included.
• Revrsed channel plan and profile sheets to accommodate both horizontal and vertical
channel adjustments Horizontal realignment from Sta. 21+00 to Sta. 25+00 (shifted
channel 5' to the north) Vertical realignment to accommodate 12" sanitary sewer line at
Bethel Road.
• Water line realignment/lowering between channel stations 27+90 73 (30 06 R) and
29+79 42 (26 46 L) Included water line plan and profile sheet
• Revrsed channel cross-sections to match new vertical alignment and revised cut/fill
quantity sheet
• Revised detail sheet to include steel plate blocking 3-5'x10' box culvert openings at
19+50 and 21+75 Deleted 2'x2' equalization openings at 21+50 +/- that were previously
required to allow storm water to exit into the existing channel
• Added gabion penetration details for RCP & flume
• Revised cover sheet and general notes

RE Bethel Road - Addendums #3A & #3B and revised Construction Phase Services
TranSystems Project No 20000890
Dear Mr Griffin
Subsequent to our meeting on February 23, 2006, TranSystems has reviewed the construction
phase scope of services currently in our contract. The purpose was to determine if certain
services, which can be provided by the City could be eliminated or reduced The result is shown
on the attached breakdown Essentially this would eliminate TranSystems' involvement in
certain bidding related tasks while reducing our involvement in certain review, site observation
and reporting tasks This would retain the record drawing and final inspection tasks with the
understanding that the City will provide us with well documented, marked up plans from city
inspectors The changes are summarized below
