To be considered by the Engineer, the request shall be in sufficient detail (as determined by the Engineer) to enable the Engineer to ascertain the basis and amount of the time requested. The Contractor shall be responsible for showing on the progress schedule that the change or event: (1) had a specific impact on the critical path, and except in cases of concurrent delay, was the sole cause of such impact, and (2) could not have been avoided by resequencmg of the work or other reasonable alternatives. The reasons for and times of extensions shall be determined by the Engineer, and such determination will be final as provided in Section 1-05 1. SECTION 1-08.9 IS SUPPLEMENTED BY DELETING THE FIRST PARAGRAPH AND INSERTING THE FOLLOWING PARAGRAPHS IN ITS PLACE: 1-08.9 Liquidated Damages Time is of the essence for this contract. The City considers it imperative that the Contractor substantially complete all work within the time for completion established in the contract The Contractor's commitment to completing these tasks by this date comprises valuable consideration for entering into this contract. Upper Meridian Valley Crk Culy Repl/Fielding I -36 May 23,2007 Project Number 05-3012 If the Contractor fails to perform as specified in Section 1-08 5, the Contractor will be in breach of this contract, and the City, as representative of the public in general, the citizens of Kent, all users who benefit from the South King County transportation network and the property owners adjacent to the project will suffer damages as a result of this breach Without limiting the foregoing, among the damages that these persons and entities will suffer include impacts to the contract work and quality control caused by paving under unacceptable weather conditions. Contract work performed after these dates will impact the performance of other project contracts and will be either more costly to perform or will be substandard Moreover, Contractor's failure to timely complete the work could significantly impact project costs, including costs of mitigating potential environmental impacts. Additionally, any delay arising from Contractor's failure to perform as specified I above will inconvenience the traveling public, obstruct traffic, interfere with and delay commerce, and increase risks to roadway users Finally, this delay will cause additional burdens to Kent taxpayers by increasing City time devoted to contract administration, engineering, inspection and supervision. Because the City finds it extremely difficult or impractical to calculate the actual cost of this delay, the Contractor shall pay liquidated damages in the following amounts: 1. If the Contractor fails to substantially complete the work by the time established in the contract, the Liquidated Damages formula established in Section 1-08 9 of the Standard Specifications shall apply the following values in order to determine the amount of liquidated damages per working day ("LD"): a. For the contract amount bid (item"C"), use the original contract amount. b. For the contract time (item "T"), compute the total number of calendar days from the date of issuance of the notice to proceed to the contract completion date. 2. If the Contractor does not achieve substantial completion by the contract completion date, the City will deduct from any money due or to become due to the Contractor, liquidated damages calculated from Section 1-08.9 for each day of delay. The City has used its best efforts to fix this amount of liquidated damages as a reasonable forecast of just compensation for the harm that will be caused from the breach, it is not intended as a penalty. In the event the City grants an extension of time for one or more calendar days prior to any of the established times for completion for a particular schedule(s), the Contractor's date for completion of the work specified herein shall be adjusted forward accordingly. 1-09 MEASUREMENT AND PAYMENT SECTION 1-09.2(1) IS REVISED BYREPLACING "TRUCKS AND TICKETS" WITH THE FOLLOWING. tUpper Mendian Valley Crk Culv Repl/Fielding 1 -37 May 23,2007 Project Number 05-3012 1-09.2(1) General Requirements for Weighing Equipment Trucks and Tickets Each truck to be weighed shall bear a unique identification number.

GEOTECl INICAL REPORT �- UPPER MERIDIAN VALLEY CREEK CULVERT REPLACEMENT PROJECT AT SE 234TH STREET,CITY OF KENT,WASHINGTON 1.0 INTRODUCTION 1.1 GENERAL This report presents the results of a geotechnical engineering study completed by HWA GeoSciences Inc. (HWA)in support of the planned replacement of the Upper Meridian Valley Creek Culvert at SE 234 h Street in the City of Kent, Washington. The objective of our work was to investigate the subsurface conditions, and provide geotechnical recommendations for design and construction of the replacement culvert. 1.2 PROJECT UNDERSTANDING Project location is shown on the Vicinity Map,Figure 1, and general site layout is shown on the Site and Exploration Plan,Figure 2. I Based on information provided by the City of Kent,we understand the City plans to remove and replace the existing 36-inch diameter CMP culvert with a new 12-foot wide by 5-foot high, 3-sided precast concrete box culvert. The culvert is being replaced ' because it overtops in a 2-year flood event. The existing culvert is 57 feet long,with upstream and downstream invert elevations of El. 409.94 feet and El. 409.61 feet, I respectively. The new box culvert will have the same length and grade as the existing culvert except that the invert grade will be 1.5-foot lower to accommodate 1.5-foot of streambed gravel in the box section. Existing road width and elevation(El. 417.0 to 417.5 feet)at the culvert location will not be changed. To facilitate construction of the new box culvert, a section of existing 8-inch diameter sanitary sewer which passes below the culvert location will be removed and replaced in a 14-inch diameter casing pipe. At this location,the bottom of the new box culvert footings will be at El. 406.61 feet,resulting in 0.93 feet of clearance between the bottom ' of the footings and the top of the 14-mch diameter casing pipe. ' 1.3 SCOPE OF SERVICES AND AUTHORIZATION Our work was conducted in accordance with our Geotechnical Work Scope and Cost Estimate, submitted to City of Kent on February 28, 2006. The work was authorized under a Consultant Services Agreement between the City of Kent and HWA dated April 3, 2006. Our scope of work included performing two exploratory borings; January 12, 2007 HWA Project No.2006-018-21 laboratory testing; engineering analysis based on the conditions observed in our explorations; and providing geotechnical engineering recommendations for the proposed replacement culvert. 2.0 FIELD AND LABORATORY INVESTIGATIONS 2.1 FIELD INVESTIGATION On April 21, 2006, HWA performed a subsurface exploration program that included drilling two exploratory borings (designated BH-1 and BH-2) to depths of 26.5 feet and 24 feet, respectively, below road grade. The drilling was subcontracted to Holocene Drilling of Fife, Washington. The borings ' were advanced using a truck-mounted drill rig employing a hollow-stem auger. The boring locations were determined approximately in the field by taping distances from existing site features. The approximate boring locations are plotted on Figure 2 and should only be considered as accurate as the locating method implies. A geologist from HWA logged the explorations and recorded pertinent information , including sample depths, stratigraphy, soil engineering characteristics, and ground water occurrence. Standard Penetration Test(SPT) sampling was performed using a 2-inch outside diameter split-spoon sampler advanced with a 140-pound hammer. During a SPT test, a sample is obtained by driving the sampler 18 inches into the soil with the hammer free-falling 30 inches. The number of blows required for each 6 inches of penetration is recorded. The Standard Penetration Resistance ("N-value") of the soil is calculated as the number of blows required for the final 12 inches of penetration. This resistance, or N- value, provides an indication of relative density of granular soils and the relative consistency of cohesive soils. Soil samples were classified in the field and representative portions placed in plastic bags. i These soil samples were returned to our laboratory for further examination and testing. The sampled soils were classified in general accordance with the classification system described in Appendix A on Figure A-1. A key to the boring log symbols is also presented in Figure A-1. The boring logs are presented as Figures A-2 and A-3. The stratigraphic contacts shown on the logs represent the inferred boundaries between soil types, and may be gradational in nature and much less distinct than represented. 2.2 LABORATORY TESTING ' Laboratory tests were conducted on selected samples obtained from the borings to characterize relevant engineering properties of the site soils. Laboratory tests included determination of in-situ moisture content and particle size analyses. Moisture content test Upper Meridian Valley-234th Street Culvert Kent 2 HWA GeoSciences Inc. January 12, 2007 HWA Project No. 2006-018-21 results are presented on the exploration logs, and particle size analyses are summarized in Figures B-1 and B-2 in Appendix B. 3.0 GEOLOGIC AND SUBSURFACE CONDITIONS ' 3.1 SITE DESCRIPTION The project site is located in a quiet, residential area in the highlands on the east side Kent (see Figure 1). At this location, Upper Meridian Valley Creek flows in a channel, about ' 10 feet in width, for approximately 10 months a year. Trees and partially-landscaped areas line the creek. SE 234th Street is an asphalt-paved, 2-lane local collector, of 29 feet width. The road pavement is cracked and shows signs of distress. The following buried utilities are some of those which were identified in the vicinity of the crossing, and have been taken into account in developing the culvert replacement design: • An 8-inch water main on the north side of the pavement. A%-inch diameter connection to the house crosses the road about 40 feet west of the centerline of the existing culvert. • An 8-inch diameter sanitary sewer down the middle of the roadway below the culvert, which connects into an 18-inch trunk sewer which continues down the center of SE 234th Street to 132°d Avenue SE. The 18-inch trunk sewer is located on the eastern side of the creek, and turns eastwards at the manhole. According to an as built drawing prepared for the Cascade Sewer District, the 18-inch trunk isewer was constructed in 1968, and the 8-inch diameter sewer was constructed in 1973. 1 • A 2-inch diameter gas line in the eastbound lane of SE 234th Street. A gas service line turns south about 14 feet west of the centerline of the existing ' culvert. • Three communication cables are located a few feet north of the 8-inch water main. • Two power cables are located about 22 feet south of the centerline of the existing 1 sanitary sewer. Upper Meridian Valley-234th Street Culvert Kent 3 HWA GeoSciences Inc. January 12, 2007 HWA Project No. 2006-018-21 3.2 GENERAL GEOLOGY Geologic information for the site was obtained from the Geologic Map of the Renton j Quadrangle, King County, Washington (Mullineaux, D. R, 1965). The map indicates that the area is generally underlain by ground moraine consisting of thin ablation till over lodgement till. Lodgement till generally consists of a dense unsorted mixture of sand, silt, clay and gravel, whereas ablation till is similar, but less dense. The map indicates that the thickness of ablation till varies widely, but is commonly 2 to 10 feet thick. 3.3 SOILS AND GROUND WATER Both borings encountered asphalt and fill over native medium dense silty sand which became dense to very dense below 12.5 to 15 feet below road level. We interpret the dense to very dense silty sand to be lodgement till, and the overlying medium dense silty t sand to be ablation till. The top of the ablation till vanes from 8 feet below road level in BH-1 to 7.5 feet below road level in BH-2 The soils encountered above this depth consist of a combination of fill and creek bank deposits. The fill typically consists of loose to medium dense, silty sand to sandy silt and,based on the ground contours, is likely about 3 to 4 feet thick. The presence of abundant organics and decomposed woody , debris towards the base of the layer is indicative of original creek bank deposits. Immediately after drilling, ground water was measured at 11.5 and 11.8 feet below ground (about 4 feet below culvert invert). However, observations of water levels during drilling can be misleading. Actual ground water levels are often higher than those observed in a boring,because borings are typically open only for a short time, and the I auger used to advance the boring can smear the side of the hole inhibiting flow of water into the boring. We anticipate that stable ground water levels likely correspond to creek water levels. We further anticipate that ground water elevations will vary depending on the season and creek water level. 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1 GENERAL The soil explorations show that the bottom of the proposed box culvert will be supported on loose to medium dense, silty sand with gravel, and in the vicinity of the sewer trench, with new trench backfill. Water is expected at about 2 feet above invert grade. These soil conditions will offer adequate support for a box culvert. The following aspects will play a significant role in the construction: Upper Meridian Valley-234th Street Culvert Kent 4 HWA GeoSciences Inc. January 12,2007 1 HWA Project No. 2006-018-21 Water Control: Temporary diversion of the creek and dewatering may be required to lower the ground water level so that the excavation and subgrade preparation as well as installation of the 14-inch diameter sleeve pipe can be performed under relatively dry conditions We do not expect significant settlement to occur as a result of limited ground water lowering to excavate for the culvert foundation. ' Excavation Support:Excavation is required through loose to medium dense silty sands. These spoils are expected to flow and heave when excavations extend to more than a few feet below the water level. However, sufficient space is available to lay the excavations back. 4.2 SEISMIC DESIGN RECOMMENDATIONS 4.2.1 Seismic Parameters ' Per AASHTO design guidelines (AASHTO, 1996), the acceleration coefficient,A, applicable for design purposes is that which is generated by an earthquake with a 10% probability of exceedance in a 50 year period, or a 1 in 475 year return interval. Data available for the USGS through their Earthquake Hazards Program website, indicates that the appropriate A value for tlus site is 0.29g. Based on the soils encountered in the ' explorations and the site geology,we recommend the site be characterized as a Type H soil profile. We recommend a Site Coefficient(S) of 1.2 for this project. 4.2.2 Liquefaction Considerations Our liquefaction analyses indicate that small pockets of loose soil below the water table down to depths of about 13 feet below road level (about 4 to 5 feet below the base of the culvert),may liquefy in a major earthquake. Although, buried culverts are typically not required to be designed to seismic design standards (AASHTO, 1996), the City should appreciate that in the event of a major earthquake, the culvert may experience some settlement and tilting and may possibly require replacement because of less than optimal flow conditions. Empirical relationships suggest that volumetric strains associated with soil liquefaction at this site may be on the order of 1.5 to 3 5 percent. Conservatively assuming that soil confinement at depth will limit lateral straining, the estimated vertical displacements associated with liquefaction may range from 1 to 2 inches below the culvert-crossing site. Some lateral spreading of the soils comprising the creek banks is probable during a major earthquake, inasmuch as the top of the liquefiable zone is near or within the base of the channel banks. However, at the crossing location, the roadway embankment and culvert will buttress the banks against sliding/spreading. Design forces that will be transferred to Upper Meridian Valley-234th Street Culvert Kent 5 HWA GeoSciences Inc. January 12, 2007 HWA Project No. 2006-018-21 the structure can be determined from the lateral earth pressure recommendations provided in Section 4.4 of this report 4.3 FOUNDATIONS We understand that the City plans to replace the existing culvert with a 3-sided,precast concrete box culvert. Because the existing fill has effectively preloaded the site, and the replacement three-sided box culvert is not anticipated to significantly increase the net loading on the underlying loose and medium dense sands, culvert settlement will be small (unlikely to exceed 1-inch) and largely a function of how much soil is disturbed at founding level during excavation for the culvert. To reduce disturbance and distribute the loads, we recommend the foundation material be over-excavated by 1-foot and replaced with a working platform of crushed rock. The replacement fill should extend to 2 feet on either side of the culvert and the base and sides of the excavation should be covered with a woven geotextile. The crushed rock should be lightly compacted by static rolling with a small drum compactor,but rolling should be discontinued if pumping of the pad and underlying subgrade becomes apparent. Additional settlement will occur if liquefaction of the loose sands occurs during a major earthquake. We anticipate total liquefaction induced differential settlement/tilt will be less than 1-inch. 4.4 LATERAL EARTH PRESSURES For determination of lateral earth pressure design parameters, we have assumed that the ' backfill against the sides of the culvert will consist of a suitable granular material. We have further assumed that the backfill adjoining the walls of the culvert will be placed to a horizontal condition at its surface and is compacted to the requirements provided for in Section 4.5. On the basis of an assumed wet unit weight of 125 pcf for the backfill and a friction angle of not less than 35 degrees, we recommend the following equivalent fluid unit weights for design purposes. Loading Condition Equivalent Fluid Unit Weight(Pc11 Active—Static (K.) 35 Active—Seismic(K kE) 40 At Rest—Static (Ko) 55 At Rest—Seismic(KoE) 80 Upper Meridian Valley-234th Street Culvert Kent 6 HWA GeoSciences Inc. January 12, 2007 HWA Project No. 2006-018-21 Passive - Static (Kp) 460 Passive- Seismic(KpF) 435 The foregoing parameters are based on fully-drained conditions. As ground water at the culvert location is expected to fluctuate in response to the stream level, water pressures are likely to act on portions of the structural elements. Accordingly, the buoyant unit weight of the soil will apply below the water table and full hydrostatic pressure must be added to that section of structure below the water table. To determine the appropriate equivalent buoyant fluid unit weight for the above cases, multiply the above values by the ratio of buoyant to drained unit weights (i.e. 0.50 in this case) and add 62.4 pcf. As indicated above, the lateral earth pressure parameters apply only to horizontal backfill conditions, and will have to be increased or decreased for sloping backfill conditions. It is also to be noted that the parameters are unfactored, and a suitable factor of safety should be applied to the passive earth pressure values for determination of restraint forces. In this latter regard, an allowable (FS = 1.5) coefficient of sliding resistance equal to 0.45 is recommend between footings and underlying granular soils for determination of sliding resistance. 4.5 BACHFILL PLACEMENT AND COMPACTION Crushed rock backfill should consist of materials meeting the requirements for Crushed ' Surfacing Base Course, as described in Section 9-03 9(3) of the 2006 WSDOT Standard Specifications for Road, Bridge, and Municipal Construction. Materials used to backfill the culvert excavation should consist of Gravel Backfill for Walls, as described in Section 9-03.12(2) of the 2006 WSDOT Standard Specifications. During placement of the initial lifts, the backfill material should not be dozed into the excavation or dropped directly on the structure. Furthermore, heavy vibratory equipment should not be permitted to operate directly over the structure until at least 2 feet (and possibly more depending on the weight of the compactor) of material is present above the crown of the culvert, unless directed otherwise by the structural engineer. In order to minimize subsequent settlement of the excavation backfill,new pavements, i and utilities,we recommended that backfill soils be placed and compacted to the ■ standards outlined in Section 2-03.3(14) C, Method B, 2006 WSDOT Standard Specifications The procedure to achieve proper density of compacted fill depends on the size and type of compactor, number of passes,thickness of the layer being compacted, and soil moisture-density properties. If access or load considerations restrict the use of 1 heavy equipment, smaller equipment can be used,but the soil must be placed in thin enough lifts to achieve the required compaction. Upper Meridian Valley-234th Street Culvert Kent 7 HWA GeoSciences Inc. January 12, 2007 HWA Project No. 2006-018-21 4.6 EXCAVATION STABILITY AND SHORING 4.6.1 General Excavation and construction of the replacement culvert must be performed in a manner that will not adversely impact existing utilities. We anticipate that excavation can be accomplished with conventional equipment such as a large trackhoe or excavator. The excavation is anticipated to have a maximum depth on the order of about 12 feet below existing road level, but could be deeper if deleterious subgrade materials are encountered at intended foundation levels. Maintenance of safe working conditions, including temporary excavation stability, is the responsibility of the contractor. All temporary excavation in excess of 4 feet in depth must be sloped in accordance with Part N of WAC (Washington Administrative Code) 296-155, or be shored. The material encountered generally classifies as Type C soil, for which WAC requires j that unsupported excavation must be inclined no steeper than 1.5H:1 V,but flatter slopes are likely necessary because of water seepage Alternatively, the excavation could be shored. 4.6.2 Open Excavations , We recommend that temporary open excavation should be sloped at no steeper than 2H:IV after local dewatering to at least 3 feet below culvert invert, but existing soil conditions may dictate even flatter slope angles. The slopes should be monitored, and slope angles adjusted in the field based on local subsurface conditions and the contractor's methods. With time and the occurrence of seepage and/or precipitation,the stability of temporary unsupported cut slopes may be significantly reduced. Therefore, all temporary slopes should be protected from erosion by installing a surface water diversion ditch or berm at the top of the slope and, in wet periods, by covering the cut face with well-anchored plastic sheets. 4.7 WATER CONTROL The contractor should be responsible for control of ground and surface water. Construction of either culvert alternative may require a suitable temporary diversion of the creek,to allow construction largely in the dry. Upper Meridian Valley-234th Street Culvert Kent 8 HWA GeoSciences Inc. January 12,2007 HWA Project No. 2006-018-21 Construction dewatering requirements depend on the time of year, creek level, recent rainfall and other factors. For this reason, construction should be performed during the dry summer season, subject to fisheries considerations and regulations. We recommend that for the purposes of estimating dewatering requirements, it should be assumed that the ground water corresponds to the creek level. Even if construction is undertaken towards the end of summer, construction dewatering may be necessary to maintain stable slopes, prepare subgrade, evaluate subsurface conditions, place crushed rock backfill, and construct the culvert. In addition, upward seepage into the excavation base can cause sand boils and/or foundation base heaving. We recommend that the proposed excavation be dewatered to maintain the ground water level at least 3 feet below the base of the excavation, and dewatering measures should be 1 implemented before excavation to final subgrade level begins. Dewatering should continue until the culvert has been placed and backfilled, and is capable of resisting hydrostatic forces. Disposal of water will be a consideration that will have to be suitably resolved with environmental and fisheries agencies having jurisdiction. We anticipate that wells or well points will be required, but this is dependent on the depth of the excavation, volume of ground water seepage, and potential presence of boiling or quick conditions in the excavation base. The latter condition will need to be evaluated at the time the excavation is undertaken, and suitable dewatering measures implemented as necessary. 4.8 WET WEATHER EARTHWORK Existing site soils are moisture sensitive to varying degrees, and may be difficult to handle or traverse with construction equipment during periods of wet weather. Therefore, general recommendations relative to earthwork performed in wet weather or in wet conditions are presented below. These recommendations should be incorporated into the contract specification and should be required when earthwork is performed in wet conditions: 1 1) Site stripping and fill placement should be accomplished in small sections to minimize exposure to wet weather. Excavation or removal of unsuitable soil should be followed promptly by placement and compaction of a suitable thickness of clean structural fill. The size and type of construction equipment used may have to be limited to prevent soil disturbance. 2) Material used as structural fill should consist of clean granular soil, of which not more than 5%passes the U.S. Standard No. 200 sieve, based on wet sieving the fraction passing the 3/4-inch sieve. The fine-grained portion of structural fill soils should be non-plastic. Upper Meridian Valley-234th Street Culvert Kent 9 HWA GeoSciences Inc. January 12, 2007 HWA Project No. 2006-018-21 3) No soil should be left uncompacted so it can absorb water. Stockpiles of excavated soil should either be shaped and the surface compacted, or be covered with plastic sheets. Soils that become too wet should be removed and replaced with clean granular materials. 4) Excavation and placement of fill should be monitored by someone experienced in wet weather earthwork to determine that the work is being accomplished in accordance with the project specifications and the recommendations contained herein. 4.9 EROSION CONSIDERATIONS Erosion can be minimized by careful grading practices, the appropriate use of silt fences and/or straw bales and by implementing the recommendations in the Wet Weather Earthwork section of this report. Surface runoff control during construction should be the responsibility of the contractor, and should be treated prior to discharge to a permanent discharge system such as a storm sewer, so as to comply with State water quality standards. All collected water should be directed to a permanent discharge system, such as a storm sewer. Permanent control of surface water should be incorporated in the final grading design. Water should not be allowed to pond immediately adjacent to foundations or paved areas. Grading measures, slope protection, ditching, sumps, dewatering, and other measures should be employed as necessary to permit proper completion of the work. 5.0 CONDITIONS AND LIMITATIONS We have prepared this report for use by the City of Kent for design and construction of a portion of this project. This report should be provided in its entirety to prospective contractors for bidding or estimating purposes;however,the conclusions and interpretations presented should not be construed as a warranty of the subsurface conditions. Experience has shown that subsurface soil and ground water conditions can vary significantly over small distances. Inconsistent conditions can occur between explorations and may not be detected by a geotechnical study. If, during future site operations, subsurface conditions are encountered which vary appreciably from those described herein, HWA should be notified for a review of the recommendations of this report, and provide revisions, if necessary. We recommend that HWA be retained to review the plans and specifications and to monitor the geotechnical aspects of construction,particularly construction dewatering, excavation, subgrade preparation,bedding and backfill placement and compaction.
