Improvements to the Oso Wastewater Treatment Plant
Corpus Christi, Texas
Contract No. 5, Treatment Plant Expansion
Second Phase of Plant Construction
CHANGE ORDER NO. 4
Job No. 9254.30
This Change Order involves the proposed paving improvements to the Oso Wastewater
Treatment Plant, and should be considered as two (2) separate items.
Item No. 1 - Substitution of the proposed heavy duty asphalt pavement section with
a 6" thick concrete pavement section.
Item No. 2 - An additional 1496 square yards of standard duty asphalt pavement
as requested by the City Wastewater Department.
PART A. NECESSITY OF THE CHANGE ORDER:
Item No. 1 - Two factors have prompted this pavement section substitution.
The first factor concerns the unpredictable and inconsistant soil con-
ditions that have been encountered in this Contract. Past evidence of
these conditions can be cited for the foundation modifications that were
required for the Sludge Dewatering Building. That foundation modifica-
tion established Change Order No. 2 to this Contract. The soil to be
encountered in the roadway construction is very expansive, and subject
to extensive lateral and vertical movement.
The second factor associated with this substitution is the extremely heavy
wheel loads to be transferred to the pavement section by the sludge
handling equipment (sludge hauling truck, 14 and 5 cubic yard containers).
Allowable wheel loads have a direct relationship to not only the type of
pavement section, but also the soil characteristics of the sub -grade
material below this pavement section.
This pavement substitution is an effort to alleviate pavement problems
common to many streets within the City subject to heavy wheel loads.
Item No. 2 - The additional standard duty asphalt pavement is at the
request of the City Wastewater Department for increased access to the
clarifier structures over and above that proposed in the Contract. This
additional pavement poses no problems with existing structures or those
structures proposed under this Contract.

PART B: DESCRIPTION OF THE WORK:
Item No. 1 - No special construction techniques will be necessary. The
proposed heavy duty equipment layout, as shown on Sheet 38 of the Construc-
tion Drawings, would be substituted with concrete pavement.
Item No. 2 - The additional standard dutu asphalt pavement would provide
increased access to the influent side of the Clarifier Structures for inlet
gate operation, scum removal operation and clean-up, scum pump maintenance,
and series pump operation.
