Specifically, reconstruct them with a 15" opening as measured from the outside face of the inside curb to the inside corner of the outside curb terminal (see sheet 16). After further discussion with the engineer, using dowels to extend the outside curb is not going to provide a durable product; therefore, as discussed during our on site meeting this past Wednesday, the outside curb and gutter at the terminal end and the inside curb and gutter at the PC for the 20' radius curve will need to be saw cut and removed and replaced with the correct 15" opening as shown in Detail 1 on Sheet 16. This will necessitate having joints at the saw cut line. Attached with this email is a spreadsheet that includes a table with station and offsets for the PC and outside curb terminal points as well as a sketch of the swale curb cut with the points identified for clarity. Additionally, the end of the concrete apron as constructed does not have the 3" drop shown on Detail 1. The apron will need to be reconstructed with either: a. 3"drop as shown on the detail or b. A 4:1 taper as had been previously discussed with Ken Zimmerman in the field. My understanding from Ken was that the 3" vertical drop at the end of the apron was difficult to construct so the City agreed with Ken's concurrence that the apron end could instead be formed with a tapered sloped at 4:1 (Y drop over 12" horizontal run as shown on Detail 1). At your earliest convenience, please provide me with your proposal for addressing the additional costs associated with reconstructing the swale inlet curb cuts as specified on the plans and this email. If you have any questions please do not hesitate to contact me. I want to make sure there is no confusion about what the City wants done. Thanks, Allen Quynn, P.E.

However, NWC disputes the issue with the 15-inch openings for the curb inlets to the swales and does not believe that this is a result of either our own or our subcontractors forces. After talking with my survey subcontractor, no termination points were provided for the curb inlets on the street side of the inlet. This information was interpreted from the plans by the surveyors, based on the radii shown on the plan view. All subsequent work to prep the curb and install the concrete curbing was based off of the survey. The lack of information from the plans and CAD files helped to create the wider openings in the field. In addition, my foreman mentioned to me previously and to everyone in the meeting today that the inlets were built to match the opening on the first one constructed. The curb on the backside of the inlets was pushed out to match the original one poured. NWC's foreman and the City of Renton's inspector discussed the issue upfront, prior to pouring the backside of the remaining curb inlets. It was decided to pour them to match the first one,which was significantly wider than the 15-inch opening shown on the plans. If there was an issue at this point, it should have been addressed prior to continuing to pour the remaining backside of the curb inlets. I am a bit confused how the City of Renton can come to Northwest Cascade after everything has been poured and claim that the issues are entirely our problem. Northwest Cascade will be performing the work as disputed work and we plan to seek compensation for performing the work. As mentioned in the meeting today, we require direction as to how the City of Renton would like the removal and replacement work performed. The City of Renton was provided several options for how the work is to be performed, and Northwest Cascade requires direction prior to moving forward with the roadway restoration. Paving the roadway depends on this answer, and Northwest Cascade had to push the paving date once because the City of Renton stated that curb &gutter would need to be removed. To reiterate, Northwest Cascade believes that the curb cuts being over 15-inches in width is a direct result of inadequate information provided and agreements between NWC and the City of Renton in the field. We dispute the remediation work and require direction as to how the City of Renton would like us to proceed.

While neat line calculations would work for a typical excavation,the work performed was not characteristic of a normal pipe laying operation. There were numerous crossing utilities that not only required a wider trench width,but made it so that the excavation could not be shored with the use of trench boxes. There were several locations along the storm and water pipe alignment where existing utilities crossed directly through or above the new pipe. At these locations,the excavation was not shorable by use of trench boxes and was shored by benching the excavation. The excavation did widen at the crossings,but otherwise stayed consistent along the pipe alignment. Further,the limits of the trench width were still within the allowable pay limits per the City of Rentods storm trench standard. The excavation was wider at the location of the utility crossings and utility conflicts for several reasons. First,the material around the existing utilities tended to slough and widened the limits of the excavation naturally. Many of the existing pipes had to be chased and relocated,which opened the trench up even wider at these locations. Numerous existing utilities did not cross the new pipe alignments at perpendicular angles. This increased the extent of the impact caused by the wider excavation because the pipe impacted NWC§trench line over a greater distance. In addition,some utilities which NWC crossed were not illustrated on the plans. This included pipes that were both in service and abandoned and left in the existing right-of-way. Crossing such utilities created a condition that would not allow Northwest Cascade to shore the excavation through the use of trench boxes and ultimately increased the quantity of gravel borrow required to backfill the excavation. Furthermore,when reviewing the bid item A-IS quantity of 540 cubic yards,something appears to be inaccurate. The Citysneat line calculations assume that NWC used only 55%imported backfill for the trench and that the remaining material used for backfill was native. The neat line calculations fall far short of accurately quantifying the volume of backfill used in the trench. NWCs truck tickets demonstrate that approximately 2,325 cubic yards(3255.85 tons)of gravel borrow for backfill have been hauled through the end of November.Even assuming that no native material has been used for fill,NWC has hauled over four times quantity called out in the specifications.Even assuming benching the trench resulted in extra excavation,that extra does not account for such a huge discrepancy in the quantity of gravel borrow used.To account for the fact that Northwest Cascade hauled in over four times the quantity of backfill shown in your neat line calculations,the average trench width would have had be over 10-feet wide. Northwest Cascade is seeking additional compensation for the gravel borrow quantity not being paid by the City of Renton. The only equitable way to determine the quantity of bid item A-18 is to use the actual quantity hauled in as measured by the truck tickets. Please advise how the City of Renton would like Northwest Cascade to proceed with the issue. Sincerely, Northwest C ascade,Inc. Jeff Collins Allen Quynn From: Allen Quynn Sent: Tuesday, November 18, 2014 10:54 AM To: 'Jeff Collins' Subject: RE: Bid Item A-18 Gravel Borrow Incl Haul Jeff, As I have discussed with you previously, it's impossible to use truck tickets to determine the quantity of back fill for the storm installation because your crew did not use shoring to support the trench but instead elected to lay the trench back by benching it. The benching resulted in extra excavation beyond the trench pay limits. The 2014 WSDOT Standard Specification states in Section 2-09.4 that gravel backfill will measured by the cubic yard in place determined by the neat lines required by the plans. It also states that the Contracting Agency will measure and pay for only the material excavated from inside the limits defined in Section 2-09.4. If Contractor excavates outside these limits or performs extra excavation as described in Section 2-09.3(3), it shall be considered for the Contractor's benefit and shall be included in other bid items. Bid Item A-18 quantities that the City has paid for to date is based on the theoretical quantity of backfilled calculated based on the pay limits of the trench. The pay limits are defined by the average trench depth, the length of pipe installed, the width of the trench as defined in Section 2-09.4. The calculated volume of backfill is therefore the total square footage of trench cross-section within the pay limits minus the area of the pipe, backfill, crushed rock and HMA. The bid item quantity of 540 CY is very conservative because it assumes 100% import with no native being placed back in the trench. So in theory, there is no way the actual truck tickets could be more than 540 CY for the backfills being placed within the trench pay limits as defined in Section 2-09.4 of the 2014 WSDOT Standard Specifications. The City will not pay for backfill placed outside the trench pay limits defined in Section 2-09.4. If you do not concur with the City's quantity of backfill paid to date for Bid Item A-18, please prepare your own calculations for the City's review. Allen Quynn, P.E.

NWC supplied,hauled, and incorporated a total of 3,255.85 tons of gravel borrow for backfill of the storm and water pipe trenches. The City of Renton has paid for 540 cubic yards of gravel backfill to date under bid item A-18 and 521.84 tons of gravel backfill under bid items B-22 and B-23. This leaves an outstanding balance of 1,412.85 cubic yards(1,977.99 tons)that NWC is owed The key items of this supplemental letter have been organized into 3 main discussion topics. These topics are as follows:the neat-line calculation of bid item A-18,conflicts while installing storm pipe,and discrepancy in backfill payment for water main bid items. For sake of ease,each item will be addressed separately below. 1. Neat-line calculation of bid item A-18. The City of Renton provided a spreadsheet,which reflects a total neat-line cubic yardage for bid item A-18 is 950 cubic yards including a 20%increase for miscellaneous usage. The City of Renton has arbitrarily reduced this quantity by 45%,providing compensation for only 540 cubic yards of gravel borrow. There is no justification provided for the arbitrary reduction or addition of the 20%. NWC was not provided any specific criteria regarding using native material for backfill. Per your request,NWC also calculated the neat-line volume of the trench backfill for the storm,which totals to 965 neat-line cubic yards without the additional 20%. This calculation can be found in the attached spreadsheet. G�a�( �-.,r jnr,r sv �./.;rr:•j Per WSDOT specification section 2-09.4,the Contractor is to be paid for the neat-line quantity cubic yardage. Nowhere in this section of specifications is a reduction in quantity discussed,nor r is this reduction justified. Therefore,the reduction of the gravel borrow quantity by the City of Renton is not consistent with section 2-09.4 of the WSDOT Specifications. NWC is owed the remaining neat-line cubic yards of gravel borrow from true. Your letter states that NWC benched all of the trenches for the storm in Iieu of providing shoring. The City provided one picture, supposedly the typical installation,of where NWC benched the trench line. The picture the City provided was of a benched excavation where an existing side sewer was in direct conflict with the pipe grade. This picture is not typical of the trench line elsewhere,and the trench in the picture was obviously widened for this conflicting utility. One can notice that on the downstream side of the ladder,the width of the excavation is significantly thinner and is within the 3.5-foot pay limits for 12-inch storm pipe per the Specifications. The fact is that Northwest Cascade did not exceed the pay limits of the trench in areas without utility conflicts. he City appears to have made a few inaccurate assumptions regarding the trench width in the picture provided in an attempt to demonstrate that the entire excess volume was for the benefit of NWC. This position simply is not supported by the facts. Per the City of Renton's assumed trench detail,a 3.5-foot trench width is shown at the bottom of the excavation. NWC scaled the bey, picture and used the 12-inch storm pipe as reference to obtain a more accurate trench width. As fir" yy NWC sees it,the actual trench width is 2.75-feet at the base of the excavation. With a 3.5-foot n. width at the top of the trench,as shown in the trench leading to the conflict,it is evident that NWC was within compliance of the trench pay limits. .1 tom, GUk kJ \04 In addition,the trench width at the top of the excavation near the ladder in the picture is not 8-feet `h in width. Using the 12-inch wide pipe saw for horizontal reference of the bench,the width of the bench is 2-feet. This brings the total trench width at the location of the utility conflict to 6.75- 4 feet. a � The height of the bench provided by the City of Renton does not scale to the height claimed by the City. NWC scaled the trench depth based on the 12-inch tall pipe saw,and came up with a depth of 2.5-feet for the section above the bench and 3-feet below the bench. The grinding limits of the trench are also addressed in the City of Renton's letter. The City is correct that the asphalt was ground to an 8-foot width between NE 12u'St and NE 161'St. Northwest Cascade made two passes with the 4-foot wide asphalt grinder because the road was to be reconstructed. The asphalt had to be removed regardless,and the means and methods used to remove existing asphalt has nothing to do with the subsurface trench widths. NWC remained within the pay limits based on the neat-line calculations in areas without utility conflicts. As stated above per NWC's calculations,the neat-line quantity of gravel borrow for the storm pipe totals to 965 cubic yards. Payment of bid item A-18 has been limited to only 540 cubic yards which is 46%of the actual neat-line quantity. NWC disputes the payment for bid item A-18 and seeks compensation for an additional 425 cubic yards of gravel borrow. 2. Conflicts while installing storm pipe. As the City of Renton is aware,NWC encountered numerous conflicting utilities during the installation of the storm pipe. For sake of convenience,they are listed below. All the following utility conflicts required excavation that could not be shored with the use of the onsite shoring. Therefore,NWC was required to excavate and backfill with gravel borrow outside of the pay limits at these locations. 1. 8/21/2014 at station 114+80-Northwest Cascade sleeved the new 18-inch pipe through the existing 24-inch pipe and set an additional manhole per the direction of the City of Renton. In order to sleeve the new 18-inch storm pipe through the existing CMP pipe, Northwest Cascade had to extend the trench substantially past the typical limits of excavation. A 3.75-foot wide by 9-foot deep by 16-foot long trench was dug in order to lower the new pipe down to the existing pipe invert and sleeve it. This added 20 cubic WyyM; yards of gravel borrow. In addition,the excavation for the manhole was 9-foot wide by 9-foot long by 9-feet deep. Backing out the volume of the 4-foot diameter structure,this S �Y kj excavation added another 22.8 cubic yards. The total gravel borrow added by this was � Dr•� 42.8 cubic yards. 2. 8/27/2014 station 111+68 to 111+53 -The existing gas service,power conduit,and telephone conduit were all at a depth of 5-feet in a 15-foot span. This created a situation where NWC could not use the trench boxes,and therefore the excavation had to be benched. There was no way to interpret the elevation of these utilities from the plans,as the elevations of the existing conduits are not on the plans. A 2-foot bench was used on either side of the trench,at a depth of 4-feet for the 15-foot span. This added 8.9 cubic yards of gravel borrow. 3. 8/28/2014 and 9/5/2014 station 109+55 -Northwest Cascade was instructed by the City of Renton to remove the existing concrete line found in direct conflict with the storm trench on 8/28/2014. The excavation was benched 2-feet back to a length of 5-feet on either side of the concrete line. At the 4-foot depth of the bench,this added 5.9 cubic yards of gravel borrow. On 9/5/2014,it was discovered that this was actually a live side ---- Z Z sewer,and NWC went back to repair the side sewer under the direction of the City of Renton. The existing gravel borrow was removed and replaced per the direction of the City. The excavation was benched,with a 20-foot long by 7-feet deep trench 3.5-feet 3 5 wide and 2-foot benches 4-feet deep on either side. This added 30 cubic yards of gravel borrow,totaling to-33:9-cubic yards for this conflict. I(' (,I 4. 9/3/2014 station 107+68 -NWC encountered another side sewer in conflict with the storm pipe grade. Once again,the excavation could not be shored through the use of trench boxes. NWC chased and relayed the side sewer on either side of the mainline trench. The benched section in the mainline alignment outside the pay limits was 20-feet long and 3-feet deep over the 2-foot cuts. This added 8.9 cubic yards of gravel borrow. The crossing trench was an additional 22-foot long by 8-foot wide at a depth of 6-feet that was benched with 2-foot cuts to a depth of 3-feet. This produced an additional f�•3 cubic yards,totaling to W.2 cubic yards of gravel borrow material. k�, 7,0 5. 9/5/2414 station 106+42-A side sewer was found to be in the grade of the new storm pipe. NWC benched 20-feet of the mainline excavation with 2-foot cuts at Meet in depth. This added 8.9 cubic yards of gravel borrow. The excavation for the side sewer crossing was 25-feet outside of the storm mainline trench. This excavation was benched as well,with a depth of 6-feet and width of 5-feet in the center. The bench was 2-foot cuts on either side at a depth of 3-feet. This crossing trench took an additional 38.9 cubic yards of gravel borrow,totaling to 47.8 cubic yards. 6. 9/8/2014 station 105+92-NWC encountered two parallel 6-inch water mains, approximately 9-feet apart,perpendicular to the storm mainline trench. The onsite trench boxes could not be utilized under the water mains,requiring a benched excavation. The excavation unraveled underneath the existing water mains,creating a 10-foot long section p �! of trench that was 5-feet deep and 2-feet past the pay limits on either side of the trench. This added a total of 7.4 cubic yards of gravel borrow. 7. 9/9/2014 station 104+88 -Another side sewer was found in conflict with the storm pipe grade. As did the previous sewer lines,this excavation required benching along the storm alignment in order to relay the sewer. The bench was cut to a depth of 2.5-feet at 2-feet of additional width on either side of the trench. There was 20-feet of benched excavation along the mainline,adding 7.4 cubic yards of gravel borrow. In addition,the crossing trench was an additional 25-foot long at a depth of 6-feet and width of 6-feet. This adds 33.3 cubic yards of material,totaling to 40.7 cubic yards of gravel borrow. l(, t 8. 9/15/2014 stations 103+00, 105+25,and 113+ 2-A meeting was held onsite between NWC and the City of Renton to discuss grade conflicts. NWC encountered numerous 5 ^^ V),Bch grade conflicts with existing utilities. Existing water mains and gas main were in conflict v with the planned storm runs headed towards the bioswales. The City of Renton directed NWC to field fit the storm as necessary to make it work. All areas of undermined existing utilities were to be backfilled with gravel borrow. The storm pipe at 113+82 could not be shored due to the two existing parallel water mains 5-feet apart. NWC excavated a 5-foot wide by 5-foot deep trench under the water mains for 12-feet. This added 1.5-feet of gravel borrow material outside the pay limits,totaling to 3.3 cubic yards. 9. 9/16/2014 station 105+25 -The existing water mains 5-feet apart had to be tunneled and trench boxes could not be used. This is due to the proximity of CB 4-5 to the existing parallel water mains along Harrington Ave NE. A 5-foot by 5-foot excavation was dug under the water mains for 12-feet. The gravel borrow overrun at this location totals to 3.3 cubic yards. 0�/ 10. 9/18/2014 station 103+00-NWC had to tunnel the two water mains on 6-foot centers in order to install the new storm. A 5-foot by 5-foot trench under the mains was made for 12-feet. This totals to an additional 3.3 cubic yards of gravel borrow used at this �lL Iocation. 11. 10/9/2014 station 118+25 -NWC dug through an unlocated,unmarked phone conduit to 1146 Harrington Ave NE. The utility company came out and relayed the conduit, widening the trench by 4-feet. The depth of the conduit was 4-feet and was 3.5-feet wide. This added an additional 4.1 cubic yards of gravel borrow. 4�.' 12. 10/1/2014— 10/14/2014 station 123+35 to 116+50-NWC potholed potential conflicts prior to installing the storm main between NE 10"'St and NE 12"'St on Harrington Ave NE. It was discovered that the existing water main running parallel to Harrington Ave NE is approximately 2 to 4-feet away from the new storm alignment. The City of Renton directed that the water main is to be backfilled with gravel borrow material and bedded with imported gravel borrow as it exposes itself. Both the City of Renton and NWC were aware that additional gravel borrow would be required during the installation of the storm between NE I O'b St and NE 12t°St. Throughout the installation of this section of storm main,an additional334. cubic yards of gravel borrow was installed to protect the existing water main Sy erm There were numerous utilities along the storm pipe alignment that presented situations that were not shorable through the use of trench boxes. The additional excavation to bench the storm trench is a direct result of the existing utilities. The gravel borrow material due to these conflicts is owed to Northwest Cascade,which totals to an additional 570.3 cubic yards. Attached is a spreadsheet that recaps the conflicts listed above. 3. Discrepancy in backfill payment for water main bid items. Northwest Cascade has not been fully compensated for the gravel borrow material used to backfill the water main trench. A total of 1,106.41 tons of gravel borrow material was used for backfill of the water main. To date,NWC has been paid for 521.84 tons of backfill material under bid items B-22 and B-23. Per WSDOT Specification section 1-09,the payment of a weight bid item is to be per the truck ticket. Both bid items B-22 and B-23 are paid per the ton,and full compensation of the tonnage quantity on the truck tickets is required. , �^ Z of Truck tickets for the 1,106.41 tons of gravel borrow utilized for backfill of the new water main can be furnished to the City of Renton upon request. As NWC sees it, an additional 584.57 tons is owed for the water main. This includes the changes to the depth of the water main along NE 10'h St,which substantially increased the quantity of backfill needed. The following tables describe the outstanding balance of gravel borrow material owed.

NWC is owed a total of $41,313.51 per the breakdown above. r In conclusion,NWC has not been paid in accordance with the specifications,which do not allow for the Engineer to arbitrarily guess at the quantities. The material was delivered to the site and the City benefitted from the usage,therefore NWC should be compensated for the total hauled to the site. NWC has provided reasonable explanations for the overruns of material. If the City of Renton disagrees with this request for additional compensation,then NWC requests a final engineer's decision on the matter so NWC can file a claim in accordance with WSDOT Specification section 1-09.11 of the standard specifications. This issue has dragged on long enough. If there are any questions or concerns, feel free to contact me at 253-848-2371.

The letter is a response to Northwest Cascade's Action Request 413 and#13A, sent on 11/8/2014 and 12/8/2014 respectively. This Action Request#13B revisits the issues discussed in the City of Renton's letter,as well as providing reasoning for each request for compensation. For ease of reading,the major components of the claim are itemized and addressed below. As stated in previous correspondence,Northwest Cascade imported 2,325 cubic yards of gravel borrow and we have truck tickets showing this quantity. Upon request,NWC can provide these tickets to further clarify the issue at hand. We believe that this cubic yardage of gravel borrow is owed,and should be paid under bid item A-18. The City of Renton has previously paid for 540 cubic yards of gravel borrow, leaving an outstanding 1,785 cubic yards of gravel borrow owed. 1. City of Renton's calculation for the neat-line quantity of bid item A-18. The City of Renton performed a neat-line calculation for the gravel borrow required for backfill, s 5 N which is 950 cubic yards. The bid item A-18 provides for 540 cubic yards of this neat-line I � ` t quantity,which totals to only 55%of the calculated neat-line quantity. Northwest Cascade does _d f HS c s S not understand the arbitrary reduction of 410 cubic yards of material and sees that the only way 1,r,� fit to remedy the issue is to pay the outstanding 1,785 cubic yards. ,�r« 13 In addition,NWC believes that the neat-line calculations for the quantity of gravel borrow are inaccurate. Representatives from CH2M Hill have stated on that the site was not topographically surveyed. With no basis for the existing elevation of the roadway,NWC disputes the accuracy of r►o'�'t'r�t� � h�''f liK CwICVf'���ti � �)� M SNv�/�w '✓r(�'4/I/K { any neat line calculations performed. The actual impact to the gravel borrow quantity is unascertainable,and the only way to accurately capture the real impact is to use the truck tickets. NU t cl�l f,z� l_GV^,A- �7�Q �•e�r OM 1`j off /•�wY �I. 6 0� CJi i� Nrr be 2. Trench width discrepancy. by fi- c, The City of Renton stated that NWC benched the storm excavation for the entire alignment of the pipe. This is not a true statement,and trench boxes were used whenever possible.,- WC began +" laying pipe utilizing trench box shoring,starting with the storm pipe headed north from NE 12Ih , s"� sv,sr*v d P�>►"', St on Harrington Ave NE. As the storm pipe depth lessened,crossing utilities began to conflict ?r�r„tr b uN s vj-,- " with the placement of the shoring boxes. Due to the location of existing utilities,NWC was `:DIr b►4- forced to utilize other means and methods of shoring in various locations during the installation Sber 1 P of pipe. The theoretical benched excavation detail provided by the City of Renton is not C representative of the trenches on the project. Further,NWC believes that any overrun of gravel borrow is a direct result of utility conflicts. The gravel borrow overrun was not a result of work e/- performed for convenience,but rather work performed for safety and legal shoring of the excavation. r �„ b� ���-Syi� Sri �r� ty6f--r- �/ 1zI+--,,►5� �1,�.-d. The high volume of utilities crossing the storm and water pipe alignments did not allow for the use of shoring boxes. Most of these utilities were not shown on the.plans. The sewer utilities NWC encountered also required significantly larger excavations and added to the total gravel 2,5 borrow quantity. The picture dated 9/9/2014 attached to the City of Renton's letter exemplifiesiL1 the situation of the increased trench width when crossing sewer utilities. Such a crossing cannot tY-P ' be shored with the use of boxes,since the boxes cannot be placed on the utility being crossed due NL to potential damage that this may cause. Furthermore,the sewer utilities had to be chased and Wi e F-1'11 relocated,effectively creating an unshorable excavation through the use of trench boxes. h I r NWC also encountered various other utilities when installing storm and water pipe. Existing _ s�v 5yI storm lines,water mains,water services,gas services,electrical conduits,and cables crossed our (uwt'1 trench in various locations which caused a change in conditions. In order to shore these locations F ^" with trench boxes,NWC would have to place the boxes on top of the utilities. Such an action P ' would have resulted in damaging the utilities and therefore the boxes could not be set above the S frlw 1t J 1 1 utilities. Trench boxes also could not be set beneath the utilities because there was not enough room between the bottom of the utilities and bottom of the excavation. Even if boxes could have been placed underneath the utilities,the shoring would still be illegal,since the top section of the to excavation could not be shored. The only legal option for Northwest Cascade was to bench the excavation at these locations. In addition,the water main elevation had to be adjusted along the NE I Oth St alignment due to t conflicts with existing utilities. This change required the pipe to be installed at depths �1 significantly greater than the minimum cover,which was an unforeseen condition. As stated in �N Northwest Cascade's Action Request#9A,the forward pricing for the water main on NE 1 Oth St F�� r assumed that all other work associated with the change is to be paid at bid item pricing. This includes additional backfill material and haul off of native soils. NWC disputes the City of Renton's claim that the excavation was shorable with the use of shoring boxes throughout the entire alignment,and requests full payment of the outstanding gravel borrow quantity. The trench excavations were within the City of Renton's allowable pay limits whenever possible. For further clarification,I have attached pictures which document the conditions described above. Below is a quick overview of the attached pictures,and what each set of pictures represents. i. Storm trench width in areas not near existing utilities.

Calculations for gravel borrow quantity. The City of Renton provided a calculation to quantify what they believe is the theoretical quantity of gravel borrow that NWC used. The"bench area"depicted by the City of Renton is neither accurate nor representative of the entire pipe alignment. Any benching performed was done so C,�j P"to due to utility conflicts,which is ultimately a change of conditions. The lack of topographic i, �' jq7 ` survey and unknown lineal footage of required benched excavation due to utilities makes an accurate calculation unachievable. N Nt L4, k""t °PP'`` The City of Renton also states in its letter that its own calculations do not explain why there is s f still a discrepancy between the truck ticket quantity and City of Renton's calculations. NWC disagrees with the calculations,an requests payment per the truck ticket total for gravel borrow. b Fw /-tot I,-- In conclusion,Northwest Cascade disputes the lack of payment for the total 2,325 cubic yards of gravel borrow,and request compensation for this quantity. NWC believes that an additional 1,785 cubic yards of gravel borrow is owed,totaling to 2,325 cubic yards of gravel borrow. At bid item pricing,the total amount for which compensation is requested'is$49,980.00. The quantity of 2,325 cubic yards of gravel borrow is based on the current information that we have regarding the issue. Northwest Cascade's total quantity may increase based on new information and calculations as it becomes available. Please respond to the issue at your earliest convenience.

POST OFFICE BOX 73399,PUYALLUP,WASHINGTON 98373 1 TOLL FREE 800-562-4442 Action Request Date: 2I6/2015 To: Allen Quynn,Project Manager City of Renton,Surface Water Utility Engineer 1055 South Grady Way Renton,WA 98057 From: Jeff Collins RE: Pervious Concrete Test Panels Sunset Community Low Impact Development Retrofit NWC#3929 Action Request#20 Allen, This letter is in response to the City of Renton's February 5,2015 email titled"FW: Harrington PHI Stairs/Paths"regarding the acceptance of the pervious concrete sidewalk test panels. Northwest Cascade(NWC)would like to clarify a few of the challenges regarding the pervious concrete testing and acceptance of the panels,as well as request direction so that the project can continue towards completion. The intention of this letter is to provide information regarding the construction and testing of pervious concrete so that a final decision can be made regarding the acceptance of the test panels. As acknowledged by the City of Renton and NWC,the microfibers intended to be batched in the pervious concrete mix were not present in the test panels. Testing the panels for conformance and as a representative sample of the future production panels was accepted by the City of Renton. The test results provided two samples that were out of conformance,which are detailed below and denoted as"Core Thickness"and"Unit Weight." Core Thickness In the City of Renton's February 5,2015 email,it is stated that the minimum thickness of fl- inches is not met for sample 1. The as-received thickness called out in the second column of the Pervious Concrete Core Test Report is in regards to the largest section of the core that was removed from the sidewalk section. When coring,additional fracture planes can be created and shear the cored section. In this case,a 4-inch section of the sidewalk was cored,but the section that the tester at Construction Testing Laboratories received was only 3.48-inches thick due to shearing of the core. Unit Weight It is also stated that samples 1 and 2 of the pervious cores did not pass the requirement for the design unit weight. However,NWC is not sure how to bring the future unit weight of the pervious concrete in to conformance with this requirement. The mix design submitted was the mix design provided(minus the microfibers),and should meet the density described on the pervious mix design submittal. Since the microfibers were not added,the unit weight theoretically should have increased,but that is not the case. NWC fears that if measures are taken to increase the density of the mix in the field by jigging, vibrating,or tamping the mix,then the porosity of the mix will be negatively impacted. Further, the installation requirements for pervious concrete per the National Ready Mix Concrete . Association and ACI 522 require that the installer does not jig,vibrate,or tamp the mix once placed. Any additional working of the material will eliminate voids and effectively reduce the porosity of the concrete. If directed to take corrective measures during installation of the future pervious concrete pours,NWC cannot guarantee the required infiltration rates noted in the specifications because such variances do not comply with industry standards. More importantly, the project schedule is dependent on the pouring of the pervious concrete. NWC offered to gift the tests panels to the City of Renton,upon acceptance of the test panels,in an attempt to remedy the missing microfiber issue. NWC has not received an official acceptance of the pervious concrete test panels. In order to reestablish progress on the project,an answer to the acceptance of the test panels is required. Northwest Cascade needs the City of Renton's final decision on the pervious concrete test panels by the end of the day today,February 6,2015,in order to move forward with the project. The subgrade has been sitting idle for weeks,and the project critical path goes through pouring the pervious sidewalk. Further,NWC protests the days waiting for a response as non-working days, since critical path work has not been able to take place. If there are any questions or concerns,please contact me at your earliest convenience. Sincerely, Nortlrest Cascade,Inc.

It appears that approximately 31LF of the pipe installation will actually differ from what is shown on the construction drawings. If the total change order is$19,450 for 551-F, that averages out to$354/1-F (which seems excessive). Water Utility will pay for 36LF(from the valve to the last 45 degree vertical bend) at$354/1.F,totaling$12,390. The remaining 19LF will be paid per Bid Item B-7 and will total $950. The total price for the work on 10th combining the change order and bid schedule would amount to$13,340. It is also our understanding that the total for the change order does not include excavation and backfill beyond what would be necessary with trench shoring in place.

As far as the fiber documentation,there is no documentation for any pervious jobs performed other than the ACI 522 specifications. All pervious projects follow these specifications, with the only difference being that the City of Renton has included fiber in the specifications. I can have Tyee provide a list of successfully completed projects that do not have fiber in the mix if the City of Renton would like to inspect other projects. On a side note, this is the first pervious project (of Tyee's) since 2006 that has required fiber in the mix design.
