1. The next Discharge Permit issued by TCEQ is assumed to be for an interim phase of 25 mgd with
1 mg/L Phosphorous. Changes from this assumption will require reevaluation and rework.
2. City of Round Rock will process City permits and may use progress sets at the identified design
levels to support permit applications. CONSULTANT is not providing any additional "permit sets"
or permit applications.Consultant will meet with code officials as detailed in the scope to identify
and review code requirements.
3. The design will be based on the federal, state, and local codes and standards in effect on the
effective date of the authorization to proceed. Changes in these codes may necessitate a change
in scope.
4. The design work on this PROJECT will last 17 months from authorization to proceed and be
completed in the February 2020 Bidding period is assumed to be 3 months.
5. CONSULTANT's design delivery process will be employed. With the exception of the final review,
the PROJECT team will not stop during formal reviews of submittals.
6. The design documents will be prepared for a single construction contract.
7. The listed permit supporting documentation will be prepared by CONSULTANT. The PARTNERS
will pay all permit processing fees.
8. PARTNERS specifications will be used as the basis for the Division 0 specifications. CONSULTANT
master specifications will be used as the basis for other technical specifications and Division 1
documents.
9. The drawings will follow CONSULTANT CAE/CAD standards. AutoCAD will be used to develop the
drawings.
10. Investigation and remediation of possible hazardous waste,asbestos, lead paint or other types of
contamination will be conducted by others if needed.
11. No existing buildings, equipment, treatment units, or facilities will be modified except as
specifically noted above.
12. Equipment described as being relocated is assumed to be in fully functional and not requiring any
modifications to operate except required rewiring and replumbing for installation in the new
location.
13. Power coordination/Arc Flash Study is not included in the Scope of Work.

14. Existing clarifier rerating is not included in this scope of work.
The following assumptions are technical in nature:
Civil/Geotechnical
1. Legal,easement or plat surveys of the existing site will not be required.
2. Site drawings will only be prepared for those areas of the plant where new facilities are to be
constructed or involving significant disturbance to existing grading.
3. The only new roadway work required is in immediate area of new and modified facilities and existing
road rehabilitation.
Structure I/Architecturo l/Geo tech n ica I
1. Conventional spread foundations will be required for new facilities. Over excavation, preload, piles,
or underdrain systems are not required. Uplift due to high groundwater levels, if any, will be
addressed with thickened base slabs or pressure relief valves in slabs. No underdrain systems or
tension systems will be required.
Process/Mechanical
1. Only hydraulic assessments required for design of the new or modified facilities are included.
2. The necessary process design, liquids/solids balance and energy balance calculations will be
performed.
3. Design concerning "plant-wide" utility systems such as basin drainage, water, and in-plant waste
collection/disposal will be limited to extensions and/or changes in existing piping. No new structures
or equipment will be needed.
4. No corrosion control provisions will be required other than materials selection and coatings.
S. Air sweep hopper system will be based on a pilot design. If during piloting, it is found to require
redesign,then additional services will be required.
HVAC and Plumbing
1. N/A
Electrical and Instrumentation& Controls Systems
1. The new instrumentation and control system will be based on the use of programmable logic
controllers. Monitoring of the plant status will be by a commercially available PC based software
package and will include plant performance trends.
