From our discussion, the pipe supplier is recommending protection of the joints that are located beneath the road. This recommendation comes from the cover of the pipe being approximately 4-feet. Black & Veatch has reviewed the arrangement and we recommend that the pipe beneath the road be protected with a concrete arch encasement. This concrete arch encasement will be as shown in Detail F/CY15. The encasement will begin south of the retaining wall and extend to the north side of the road, as indicated on the attached sketch.

Drawing No. MSS CONTRACTOR REQUESTS: ®information 0 interpretation 0 Clarification Drawing MS6 calls for the Suction Piping for the two New Penn Valley Double Disc Pumps to have two 90-degree horizontal bends prior to entering the Pumps. The Manufacture recommends that the Suction Piping not have these horizontal bends (the suction piping from the Gravity Belt Thickeners should be in line with the Suction of the TWAS Pumps). Please note that this is a minimum requirement. The manufactures best -case scenario would be for the horizontal suction & discharge to be in line with the Pump. Please get with the Plant to see if you want this piping changed. Se the attached letter from SWEET and their drawing. CONTRACTOR'S PROPOSED SOLUTION: REQUESTED BY: DATE: 11/25/09 ENGINEER'S RESPONSE: 91 Information ❑ Interpretation O Clarification For the items described above or in the attached material referenced: See attached for response. RESPONSE BY: Laura A. Stratton/al DATE: 12/11/2009 SASandflZaple Caftactlnp FllesUab FlIesN 71 - Lubbock WMPIRM'SWI-104-TWAS Suction Plping.doc RFI-104 Response, 12/11/2009 There are two options to remove the horizontal bends from the suction piping. See attached sketches. After reviewing the associated cost, a decision will be made on which Option to incorporate. Option 1: This involves moving the horizontal bends to the discharge piping. The discharge piping will connect to the existing header in the location indicated on MS6. All of the existing pipe as designed would be reused, just in a modified configuration. The 10-112" spool piece (Item 1318 from Ferguson drawing B04217) will be placed on the suction side of the pump, after the two 900 bends. The 8-114" spool piece (Item 1316) will be located between the check valve and the diaphragm valve on the discharge. The modifications apply to all three trains. The Contractor shall submit a cost proposal to make the piping modifications to the train with existing pump P-2502. Option 2: This involves providing a straight run of pipe on both the suction and the discharge side. Most of the pipe would be used in a modified configuration. The 10-1 /2" spool piece (Item 1318) will be placed on the suction side of the pump, after the two 900 bends. The 8-1/4" spool piece (Item 1316) will be located between the check valve and the diaphragm valve on the discharge. The Contractor shall use EBAA Iron series 2100 Megaflanges, or other equal wedge -style restrained flange system, where making the connection of the existing Tee into the new location on the discharge header. A flange system that uses set screws is not acceptable. The modifications apply to all three trains. The Contractor shall submit a cost proposal to make the piping modifications to the train with existing pump P-2502. The cost shall also include the work for cutting into the existing header and reinstalling the existing Tee. A credit should be indicated for not installing Item 1323, 1325, and two pieces of Item 1315. These pieces of pipe would be handed over to the Owner.

The Owner will now be responsible for start-up and resetting Pump 2502 switches. Option #2 entails realigning the pumps Suction and Discharge lines to be in line with the Pumps. We have added two existing 6" Diaphragm Valves in the reworked Discharge Header because the Plant Personnel have voiced a wish to have them. The addition of these valves will allow us to keep pumps on line while we perform this work. We will start by installing Pump 2501 1" since the existing pump is about to fail. During the tie-in of this pump all three pumps will have to be off line. Amer this Pump is running and the diaphragm valves are installed then the Plant will have at least one pump on line during the installation of the other pumps. The Total Lump Sum Amount we request for Option #2 is Nine Thousand Three Hundred and Seventy Six Dollars and Ninety -Six Cents ($9,376.96).
