Title
Consider and take action on a resolution authorizing Amendment 1 to the Professional Services Agreement with Sander Engineering Corporation for the Bay Colony 2 Parkside Lift Station Relocation Project (WW2601) for additional engineering design services in an amount not to exceed $56,313.00 (Executive Director of Capital Projects)
Background:
Approval of this resolution will authorize Amendment 1 to the Professional Services Agreement with Sander Engineering Corporation for the Bay Colony 2 Parkside Lift Station Relocation Project (WW2601) for additional engineering design services in an amount not to exceed $56,313.00.
The lift station relocation was necessitated by the acquisition of the property by TxDOT for the SH 99 -Grand Parkway. This Amendment 1 is due to a change in the proposed lift station relocation site. The original scope of work located the proposed lift station site on the back of property owned by an existing Walgreens Store. However, upon further coordination with TxDOT, their design consultant, and their acquisition agent, it was determined that City should consider other site options on adjacent open reserve tract owned by the Bay View HOA to expedite acquisition and future access to the facility. City staff coordinated and presented three options to the Bay View HOA. The HOA and City mutually agreed that Site Option 3, adjacent to Brookport Drive, is the most suitable site. This was confirmed by the HOA (See attached letter and site options exhibit). The required additional engineering and surveying work due to the location change is as follows:
- Additional topographic surveying
- Preparation of an additional 20-foot Utility Easement
- Preparation of an additional Temporary Construction Easement (as needed)
- One additional geotechnical boring
- Design of approximately 280 linear feet of additional gravity sewer
- Design of approximately 400 linear feet of additional force main
- Addition of an Odor Control Unit at the proposed lift station
The additional project fees breakdown is as follows:
1. Preliminary Basic Design Phase $ 13,000.00
2. Final Basic Design Phase $ 15,600.00
3. Special Services Total (Survey & Geotech) $ 21,713.00
4. Bid Phase $ 1,500.00
5. Construction Administration Phase $ 4,500.00
Total $ 56,313.00
Upon the completion of the final design, City and TxDOT will sign a Standard Utility Agreement for the City to be fully reimbursed for all the eligible costs associated with this facility relocation. The previous pre-design construction estimate of $1.736M is also updated to $2.065M to include above additional work. Estimate will be updated throughout the design phase.
