Step 3 Grant No. C-48-1214 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. i Change Order No. 4 Page 2 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.
