| 1. | Use the following criteria in determining pipe sizes: |
| a. | Existing known or estimated demands or flows. |
| b. | Future known or estimate demands or flows due to expansion of area served, new buildings or building additions. |
| c. | Steam distribution and condensate return piping and electric cable sizing will be based on existing sizes and campus requirements. Discuss these with Capital Projects (CP). |
| 2. | Show or note the following on the plans: |
| a. | Existing and future surface grades where there is to be a change. |
| b. | Invert elevation of sewer and drainage structures and pipe. |
| c. | Rim elevation of manholes and drainage grates. |
| d. | Percent of slope where drainage and velocities are a factor. |
| e. | Any intersecting or closely parallel utilities or obstructions, new or existing, that may cause interference. |
| f. | Provide a profile to determine clearances and show the above required information. |
| g. | Coordinates of manholes and catch basins from University grid. |
| 3. | For piping tests see Appendix. Pipe testing requirements vary. Discuss with Capital Projects (CP). |
| 4. | Base all elevations on Berkeley campus datum. Do not use City of Berkeley or United States Geological Studies (USGS) datum unless outside of campus property. Indicate datum used on the drawing. |
| 5. | Verify with project manager availability of utilities needed during construction. |
| 6. | Clearly identify who pays for construction utilities. On major capital projects University of California pays for water but Contractor pays for electrical power, meter, transformer and connections and is responsible for their installation. |
| 7. | Use the following criteria in determining pipe sizes: |
| a. | Obtain design loads from University of California. |
| b. | Specify equipment such as lift stations. |
| c. | Contractor must maintain equipment (e.g., lift station, etc.) during construction. |
| 8. | Specify dewatering requirements during construction. |
