The work includes installing welded angle irons posts and rails on the inside of the 42-inch steel casing, setting the rails to design grade for the 34-inch carrier pipe, plugging both ends of the 42-inch casing with bricks and grout, installing vent pipes, plugging and filling the 34-inch carrier pipe with water, and blowing sand into the annular space between the 42-inch casing pipe and 34-inch pipe so the 34-inch pipe is supported by sand for its entire length. The wood skids in the original design are deleted and a credit for the deleted work and materials is included in the JWFowler Change Order Proposal. The change order includes all labor, equipment, materials, and taxes needed to accomplish the work. The cost is based on the JWFowler Change Order Proposal COP-011, dated 12/17/11, and attached to this change order. The additional work days requested by JWF with daily costs incurred are not included or approved in this Change Order. JWF will need to submit a separate change order request explaining and justifying why the change in work resulted in additional working days to the project schedule. All daily costs requested must be detailed and backup documentation (i.e. invoices, rental receipts, machinery rates) must be provided with the change order request. Measurement for payment will be prorated as the work is accomplished. The unit contract price shall be full payment for all Work needed to complete the sand fill in the steel casing pipe. Cost= $6,716.01 per LS = $6,716.01 CO-3B Boring#3, Blown Sand Fill for Casing Pipe per LS This change order is to fill the 42-inch steel casing pipe for boring#3, from CB-5 to CB-6, with blown sand. The work includes installing welded angle irons posts and rails on the inside of the 42-inch steel casing, setting the rails to design grade for the 34-inch carrier pipe, plugging both ends of the 42-inch casing with bricks and grout, installing vent pipes, plugging and filling the 34-inch carrier pipe with water, and blowing sand into the annular space between the 42-inch casing pipe and 34-inch pipe so the 34-inch pipe is supported by sand for its entire length. The wood skids in the original design are deleted and a credit for the deleted work and materials is included in the JWFowler Change Order Proposal. The change order includes all labor, equipment, materials, and taxes needed to accomplish the work. The cost is based on the JWFowler Change Order Proposal COP-012, dated 12/20/11, and attached to this change order. The additional work days requested by JWF with daily costs incurred are not included or approved in this Change Order. JWF will need to submit a separate change order request explaining and justifying why the change in work resulted in additional working days to the project schedule.

Measurement for payment will be prorated as the work is accomplished. The unit contract price shall be full payment for all Work needed to complete the sand fill in the steel casing pipe. Cost=$7,822.43 per LS= $7,822.43 CO-3C Unused 42-inch Casing Pipe per Linear Foot The boring from CB-4 to CB-3 encountered buried metal and wood debris that jammed the auger twice, requiring the contractor to dig down to the auger to free it. After encountering the problem for the third time,the City decided to stop boring and install the remaining portion of the pipe from CB-4 to CB-3 by open cut. Because of the change to open cut 94 linear feet of steel casing was not installed between CB-4 and CB-3. JWF COP 015.01 showed that a total of 450 LF of casing pipe was purchased for the project, including the 10 feet of casing needed for the auger steering head and 8 feet of excess casing that would be cut off and scrapped at the end of boring runs. The bid quantity for the casing pipe was 432 linear feet. The prorated material cost per linear foot of installed pipe is$134,695/432 LF=$311.79 per LF plus 9.5%tax. The total material cost for the unused pipe is$341.41 per LF The change order includes all labor, equipment, materials, and taxes needed to accomplish the work. The cost is based on the JWFowler Change Order Proposal COP-015.01,dated 12/20/11, and attached to this change order. Estimated Cost=$341.41 per LF x 94 LF=$32,092.54 TOTAL CHANGE ORDER COST= $46,630.98 Additional Working Days added to the Contract for this Change Order: 0 days ORIGINAL CONTRACT AMOUNT CURRENT CONTRACT AMOUNT ESTI MATE D N ET CHAN G E ESTIMATED CONTRACT THIS ORDER TOTAL AFTER CHANGE $994,925.00 $1,017,841.05 $46,630.98 $1,064,472.03 SIGNATURES: -- Contractor: Date: �P A Project Engineer: .-� ✓\ Date: — 12-12 Approved By:,, `c'� ,� '�6 r Date: l,___'' (Utility Systems Director) H:\File Sys\SWP-Surface Water Projects\SWP-27-Surface Water Projects(CIP)\27-3529 Lake Ave-Rainier Ave\1607 Change Orders\CO-3b FINAL Blown Sand 2-3 CasingPipe.doc\DCtp James W Fowler Co. v General Cuntrllctors CHANGE ORDER WORKSHEET PROJECT Lake Ave S/Rainier Ave S Project No: 2011-05 Date: 12/19/2011 OWNER: City of Renton Work Description: REF#'s COP 011.00 Bore#1 sand filled casing pipe CC# 999000-011 a $ClS�"S HOURS RATE TOTAL ' CLASSIFICATION REGULAR OVERTIME REGULAR OVERTIME COST Laborer Credit for wood skids (16.00) - 44.93 - (718.94) Welder _Labor for adding 1"angle iron skids 24.00 - _ 56.56 - 1,357.51 Laborer Grout ends for seals_ 16.00 - 44.93 - 718.94 Laborer Blow sand in pipe 12.00 - 44.93 - 539.20 Laborer Fill 36"pipe w/water 16.00 - 44.93 - 718.94 TOTAL LABOR COST 52.00 - 2,615.65 LABOR MARKUP 29% 758.54 GRAND TOTAL LABOR 3, '. . 7I1'MEhl7 COSTS.
