Bean Date END CHANGE ORDER NO. 2, B2001-063 uly 26, 2oo2 Mike Yost Brazoria Drainage District No. 4 4805 Broadway Pearland, Texas 77581 Ref. SWEC Detention Basin Dear Mike: This letter presents segments of our revised proposed Change Order No. 2 (copy enclosed) to our contract with Bean Construction Company. The only difference between this letter and my July 18 letter to you is the reduction in Item 3., f., "Dispose offsite brush & debris from BDD4 Exc.". The revised amount is $3,000 instead of $30,000 in my July 18 letter. As I said there, these Change Order segments are proposed by the City to help an early completion of the detention basin, and to relieve BDD4 from the detail work of fine grading and inlet and piping work. Change Order No. 2 Segments: "2. Re-work existing E-Inlet and 60" CMP at southeast :comer of East Pond SOuth of Blue Line (BDD4 area) by removing the upper 60" pipe and sealing manhole at the upper entry, salvaging 60 feet of the 60" CMP and with three new connection bands extend lower 60" to match construction drawings, and clean manhole and grade outlet as shown on construction drawings. Remainder of removed 60" CMP shaJl become property of the Contractor and shall be removed from the site. Amount of Item 2. $11,609 3.

Sheet 2 of 2 TOTAL AMOUNT OF 2. and 3. (Above) $711,921 In our pre-construction interlocal agreement last October, BDD4 agreed to accept performance responsibility represented by cost estimates (copies enclosed) for these items that resulted in approximately 47.6% (copy of calculation enclosed) of the total estimated cost of the respective items. Please consider assuming responsibility for 47.6%, or $34,234 of the total mount of these Change Order No.2 segments of $71,921. (Clearing and disposal work already done by BDD4 has been recognized. Only a small amount remains to be hauled off site.) This would be in return for relief from performance of those tasks.. In our opinion, this change order will result in an earlier completion of SWEC Detention Basin, thereby better meeting expectations of citizens, and will remove from the responsibility of BDD4 the fine grading and detailed concrete and inlet and pipe setting work entailed. An early reply would be greatly appreciated. . .H~irgrO~e, P.E.
