Dear Laura, Eagle Contracting, L.P. requests the Total Lump Sum Amount of Three Thousand Five Hundred and Eighteen Dollars and Fifteen Cents ($3,518.15) to provide the revisions called for in the Engineers answers to RFI-061 to the Ferric Feed Piping at the Primary Distribution Structure and BNR Basins 1-3. We also request one day of time extension. This proposal does not include flanges on the Teflon piping. We are using threaded pipe and fittings. This proposal does not include pipe insulation for the PVC ferric piping inside of the Primary Distribution Structure. We feel that this piping will not freeze for the following reasons. First, the raw sewage coming into this structure will heat the interior (always above freezing). Second, the structure has covered grating. Third, the incoming piping is buried (always above freezing). We are using SS Unistrut to support the vertical Teflon piping due to the restricted space between the corner and the Slide Gate. Please note that we have to get these revisions made in the next week or so to meet our start-up schedule for the IMLS. The Teflon pipe is special and will have to be ordered. We are told to expect a two -week delivery tirne from the time of order. With Kind t Reg , Ger�a �nt Project Manager cc: File (Proposals) & Field P.Q.

They are as follows: I have attached a data sheet for Teflon Pipe and Fittings from Ryan Herco. I believe that this is the type of Pipe that you are asking us to use inside the Primary Distribution Structure for the Ferric Piping. We cannot purchase teflon coated steel fittings. Can we use this teflon pipe and these teflon fittings from Ryan Herco? This pipe and ifs fittings are made for threaded connections. Can we eliminate the flanges and use threaded 90 elbows in lieu of the flanged connections you cafl for? You have asked us to insulate the Schedule 80 PVC Pipe inside of this structure. I would like to eliminate this pipe insulation_ I do not believe it will be neccessary (the raw sewage entering this structure will keep the temperature inside the structure considerably above freezing. i I would like to use stainless steel unistrut wlss clamps to strap the verticle teflon pipe drop down to the diffusser. We have very little room between the corner of the structure and the gate opening to put a pipe support. This is why I need to use a unistrut support. i I would like to use a stainless steel pipe hanger to support the schedule 80 PVC pipe in lieu of the painted steel pipe hanger you call for. Will this be acceptable? Please get me your answers as soon as possible so I can order this piping. Thank You, Glenn Grant Eagle Contracting, L.P. http://us.me5.mail.yahoo.com/mc/sbowMessagc?fd=Sent&soresdate,&order=down&star Mid=O&.rand=l3... 1/27/2009 REQUEST FOR INFORMATION FPROJECr.

Provide an engineered system to support the duct bank over the excavation. Since there are several butterfly vales in the vicinity, the support system should be left in place so that the duct bank is protected during any future excavation work. 2. The 42-inch effluent lines should be modified as attached to be routed beneath the electrical duct bank. The invert elevation of both effluent lines shall be the same. The invert will be approximately 3128.77. This elevation will be determined by the invert elevation of the existing 42-inch Chorine Contact Effluent to EPS 1. The new UV Effluent to EPS 1 ties into the existing Chlorine Contact Effluent to EPS 1. The piping beneath the slab should be encased in concrete. 3. Extend the 42-inch UV Effluent to Reaeration so that it extends approximately 35 feet past the UV facility in lieu of the 10 feet indicated on sheet CY2. See the attached profile for routing. The Contractor should coordinate with the pipe supplier to determine if beveling the pipe is possible to achieve the elevation change from 3128.67 to 3123.5 in lieu of installing bends. The Contractor should provide a cost proposal for the changes in the work. The cost proposal should show credits and charges to account for the changes indicated in this RFI response. a cif d?'

Pearson Keller, TX 76248 Re: Southeast Water Reclamation Plant - Lubbock, Tx. Gentlemen, This document covers the support of the existing duct bank at the above referenced project. Information used to develop this support system was taken from the project plans, the geotechnical investigation, and the contractor's sketch of existing conditions and approximate locations of the proposed support members. The geotechnical report indicates four borings in the general vicinity of duct bank. They are B-15, B-16 B-20, & B-21. Review of the four boring logs suggests that the subsurface conditions vary with respect to the indicated "sandstone" layer; therefore, bearing pressure and friction values stated in the geotechnical report were used to determine penetration depths of the concrete encased support beams to support a theoretical duct bank length of twenty (20) feet. Calculation of anticipated forces has been based on the following assumptions. The duct bank has been measured to be 3 feet wide and 2 feet deep. It is assumed to be intact, with no cracks or defects. Six 6" conduits are enclosed in the duct bank. Duct bank concrete assumed to be 3500 psi. Steel re -bar was conservatively neglected in the calculation to determine the potential maximum span of the duct bank. Piers and transverse support beams to be W12x53's. A friction factor of 0.3, as stated in the geotechnical report (the conservative number), and a bearing pressure of 2 kips per square foot were used to determine depth of penetration required to support the calculated weight of the support system. 828 HvWUL DRIVE 972-5011-2171 COBPEU, TES 75019 Under the above assumptions, and conservatively assuming simple support conditions, the maximum permissable span was determined to be 32 feet; however, the contractor's sketch (attached) of probable locations of support piers indicates spans will be approximately half that length. For conservatism, calculation of loads acting on the support piers is based on twenty foot spans of the duct bank. Combined loads include the weight of 1/2 duct bank and support beam along with the steel pier, a portion of which will be encased in concrete which translates to 13,070 lbs. Using the friction factor of 0.3 and bearing values, a pier embedded twenty feet below grade will produce the required resistance to support some 13,431 lbs.. Respectfiflly, hn .
