RE: Submission of Revised Contract Amendment No. 1,
Main M-21 Drainage Area, Sanitary Sewer Rehabilitation and Improvements
(Group 7, Contract 3), Part 8, Units 1, DOE No. 2081
Sewer Project No. PS46-070460410310
WADE File No. 9713
Dear Mr. Boyer:
We are resubmitting Amendment No. 1, as requested, to the above referenced
contract to account for additional work beyond the original scope of work that
includes the recovery of costs associated with bidding three (3) more project units
more than was authorized under our contract. We are also seeking to recover design
costs for the preparation a junction structure design for the M-21 outfall into M-275.
In addition we are seeking to recover costs associated with the re-design of an
accepted Hwy 287 crossing design for M-21 as requested by the City after TxDOT
permitting was completed. This Hwy 287 crossing redesign also required the
modification of two existing TxDOT permits. Both of these design changes were
requested during final plans review and involved substantive plan edits.
Specifically, we are seeking approval of the following additional work items in this
amendment request as described below:
Design Services: Sewer Pipeline Relief for the M-21 Drainage Area
• Additional Construction Projects (Units) Bid: The original contract outlined
the advertisement of 6 construction projects, but 9 project units were actually
advertised under this agreement. For simplicity, we are using the Part 8 project
plans which had three (3) project units, as the representative project units that
exceed the contract amounts. The table below reflects our labor costs associated
with preparing extra plan sets, bid tabulations, as well as printing, and plotting
costs. The costs are summarized as follows: �(1�

• M-21 Junction Structure Design: The preliminary plan review did not identify
the need for constructing a large junction structure at the intersection of M-21
and M-275 since the City had not addressed sewer main relief alternatives for
M-275 which could substantively alter the present sewer system configuration.
During the final review process, we were requested to design a junction
structure. The costs associates with this items are as follows:
Staff/Item Hours Labor Direct Total
Ex enes Expenses Expenses
Senior Engineer 4 $ 403.16 $ 403.16
($100.79/hr)
Senior Office 12 $ 731.28 $ 731.28
Technician
($60.94/hr)
TOTAL: $ 1,134.44
• M-21 Relief Sewer Hwy 287 Realignment Design: The last item being
addressed under this contract amendment is the design of a revised alignment of
M-21 across US Hwy 287, including the revision of a TxDOT permit associated
with this location. The highway crossing involved the re-design of 555 LF of
20-inch sanitary sewer that required extensive coordination with the City,
TxDOT, Koch Industries and other public utilities. Based on the unit fee for
design in this contract of $13.88/LF, we have backed out the survey costs of
Wade & Associates, Inc. ,.

$2.42/LF for a revised design unit price of$11.46/1-F. However, since much of
the area had been previously laid out, the level of effort to design the M-21 re-
alignment was reduced to account for that fact. Therefore, we further reduced
the unit design fee by 40 percent to account for this fact, yielding a computed
unit price of $6.88/L.F. Therefore, the redesign of 555 LF of M-21 across US
Hwy 287 equals $3,818.40. In addition, we are seeking another permit fee of
$500.00 to cover the cost of amending two existing TxDOT permits since we
had to file revised plans and paperwork. Therefore, we are requesting $4,168.40
to cover costs associated with this amendment item.
The table below summarizes all of the costs identified in this contract amendment:
Item Total Expenses Itemized
Additional Construction Projects (Units) Bid $ 8,524.70
M-21 Junction Structure Design $ 1,134.44
M-21 Relief Sewer Hwy 287 Realignment $ 4,168.40
Design
TOTAL: $ 13,827.54
Therefore, we are requesting Revised Contract Amendment No. 1 in the amount of
$13,827.54 to. the M-21 Agreement. This amendment would increase the total
contract amount from $910,509.00 to $924,336.54, representing an increase of 1.52
percent (1.52%). In addition to the above, we had to re-design M-21,L-774,Line D
and various sewer line extensions on this project. We will discuss these items with
you in the near future.
Please expedite this request and do not hesitate to contact me should you have any
questions or need any background information concerning this matter. Thank you
for your time and consideration.
