The project also includes the excavation and transportation of fill material and the placement of fill material. The installation of concrete block revetment mats, the installation of concrete sills, buried riprap, and the preparation of all disturbed areas for revegetation. 1.02 QUALIFICATIONS The CONTRACTOR must show proof to have completed at least 3 projects involving dewatering or concrete block revetment mat. 1.03 WORK SEQUENCE A. The Work Sequence is to be submitted as part of the construction schedule required in Section 01320. Construction of the project shall begin within seven (7) calendar days of the date of Notice to Proceed unless approved by the ENGINEER. The date of beginning and the time for completion of the work are essential conditions of the Contract Documents and the work embraced shall be commenced on a date specified in the Notice to Proceed. The CONTRACTOR will proceed with the work at such rate of progress to ensure full completion within the contract time. It is expressly understood and agreed, by and between the CONTRACTOR and the OWNER that the contract time for the completion of the work described herein is a reasonable time, taking into consideration the climatic and other factors prevailing in the locality of the work. Every effort shall be made by the CONTRACTOR to complete the project within the "Contract Time" shown in the proposal. The "Contract Time" anticipates "Normal" weather and climate conditions in and around the vicinity of the Project site during the times of year that the construction will be carried out. Extensions of time based upon weather conditions shall be granted only if the CONTRACTOR demonstrates clearly that such conditions were "unusually severe," would not have been reasonably anticipated, and that such conditions adversely affected the CONTRACTOR’s work and thus required additional time to complete the work. The following specifies the procedure for the determination of time extensions for unusually severe weather. The listing below defines the anticipated number of calendar days lost to adverse weather for each month and is based upon National Oceanic and Atmospheric Administration (NOAA) or similar data for the geographic location of the project. LPATH Berm Erosion 01010-2 Summary of Work Protection Measures Monthly Anticipated Calendar Days Lost to Adverse Weather Conditions JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC (7) (4) (4) (4) (6) (3) (4) (2) (3) (3) (2) (5) The above schedule of anticipated adverse weather will constitute the base line for monthly (or portion thereof) weather time evaluations. Upon acknowledgment of the Notice to Proceed and continuing throughout the contract on a monthly basis, actual adverse weather days and the impact of adverse weather days that delay the work will be recorded on a day-to-day basis. It is assumed that the work will be carried out Mondays through Fridays (holidays excepted) unless an approved construction schedule or written authorization from the OWNER indicates otherwise. The number of days of delayed work due to adverse weather or the impact thereof will then be compared to the monthly adverse weather schedule above. An actual adverse weather day must prevent work for 50 percent or more of the CONTRACTOR’s workday, delay work critical to the timely completion of the project, and be documented by the CONTRACTOR. The City Representative observing the construction shall determine on a daily basis whether or not work can proceed or if work is delayed due to adverse weather or the effects thereof. The CONTRACTOR shall notify the ENGINEER in writing of any disagreement as to whether or not work can proceed on a given date, within 2 calendar days of that date. The OWNER will use the above written notification in determining the number of working days for which work was delayed during each month. At the end of each month, if the number of working days for which work was delayed due to adverse weather exceeds that shown in the above schedule, a Change Order will be executed which increases the Contract Time. The number of work days delayed due to adverse weather or the impact thereof will then be converted to Calendar Days based on the contract completion day and date. This conversion assumes a 5-day work week, Mondays through Fridays, holidays excepted; should the CONTRACTOR have authorization to work weekends and/or holidays, then the method of conversion of workdays to calendar days would take this into consideration. The contract time period will then be increased by the number of calendar days calculated above and a new contract completion day and date will be set. The CONTRACTOR’s schedule must reflect the above-anticipated adverse weather delays on all weather-dependent activities. While extensions of time shall be granted for "unusually severe" weather or climate conditions, the OWNER shall make no monetary compensation for any costs to the CONTRACTOR arising out of such delays. The CONTRACTOR shall comply with the portions of the Contract Documents relating to his project schedule and amendments thereto which result from the "unusually severe" weather condition. Breakdowns in equipment or lack of performance by the CONTRACTOR will not be considered justification for an extension of time. Liquidated damages will be assessed as delineated elsewhere. LPATH Berm Erosion 01010-3 Summary of Work Protection Measures The CONTRACTOR shall not be charged with liquidated damages or any excess cost when the delay in completion of the work is due to the following, and the CONTRACTOR has promptly given written notice of such delay to the OWNER or ENGINEER. 1. To any preference, priority, or allocation order duly issued by the OWNER. 2. To unforeseeable causes beyond the control and without the fault or negligence of the CONTRACTOR, including but not restricted to, acts of God, or of the public enemy, acts of the OWNER, acts of another CONTRACTOR in the performance of a contract with the OWNER, fires, floods, epidemics, quarantine restrictions, strikes, freight embargoes, and abnormal and unforeseeable weather as provided above. 3. To any delays of Subcontractors occasioned by any of the causes specified in paragraphs 1 and 2, above. Other than the conditions above, CONTRACTOR is permitted to start the work at any location within the project site. The CONTRACTOR shall adhere to the construction traffic control requirements delineated in Section 01555 and on the Drawings. 1.04 UNDERGROUND UTILITIES A. It shall be the responsibility of the CONTRACTOR to verify the existence and location of all underground utilities along the route of the work and to coordinate the construction schedules with these utility owners. B. Known utilities and structures adjacent to or encountered in the work are shown on the Drawings. The locations shown are taken from existing records and the best information available from existing utility plans and from field potholing, however, it is expected that there may be some discrepancies and omissions in the locations and quantities of utilities and structures shown. Those shown are for the convenience of the CONTRACTOR only, and no responsibility is assumed by either the OWNER or the ENGINEER for their accuracy or completeness. C. The CONTRACTOR shall field verify all utilities and coordinate construction with utility owners prior to starting construction. The CONTRACTOR shall be responsible for protecting utilities during construction and scheduling utility adjustments to eliminate conflict with progress of the work. D.

LPATH Berm Erosion 02240-1 Water Control and Dewatering Protection Measures SECTION 02240 WATER CONTROL AND DEWATERING PART 1 GENERAL 1.01 SECTION INCLUDES A. The work of this section consists of controlling groundwater, site drainage, and storm flows during construction. The CONTRACTOR is cautioned that the work involves construction in and around drainage channels, local streams or rivers, and areas of local drainage. These areas are subject to frequent periodic inundation. 1.02 RELATED SECTIONS A. Section 02315 – Excavation and Embankments PART 2 PRODUCTS 2.01 MATERIALS A. On-site materials may be used within the limits of construction to construct temporary dams and berms. The materials such as plastic sheeting, sand bags, and storm sewer pipe may also be used if desired by the CONTRACTOR. PART 3 EXECUTION 3.01 CONSTRUCTION REQUIREMENTS A. General: For all excavation, the CONTRACTOR shall provide suitable equipment and labor to remove water, and he shall keep the excavation dewatered so that construction can be carried on under dewatered conditions where required by the Drawings and Specifications. Water control shall be accomplished such that no damage is done to adjacent channel banks or structures. The CONTRACTOR is responsible for investigating and familiarizing himself with all site conditions that may affect the work including surface water, level of groundwater and the time of year the work is to be done. All excavations made as part of dewatering operations shall be backfilled with the same type material as was removed and compacted to 95% of Maximum Standard Proctor Density (ASTM D698) except where replacement by other materials and/or methods are required. The cost for this excavation and backfilling shall be included in the Construction Dewatering bid item. The CONTRACTOR shall conduct his operation in such a manner that storm or other waters may proceed uninterrupted along their existing drainage courses. By submitting a bid, the CONTRACTOR acknowledges that he has investigated the risk arising from such waters and has prepared his bid accordingly, and assumes all of said risk. At no time during construction shall the CONTRACTOR affect existing surface or subsurface drainage patterns of adjacent property. Any damage to adjacent property resulting from the CONTRACTOR’s alteration of surface or subsurface drainage patterns shall be repaired by the CONTRACTOR at no additional cost to the OWNER. CONTRACTOR shall remove all temporary water control facilities when they are no longer needed or at the completion of the project. LPATH Berm Erosion 02240-2 Water Control and Dewatering Protection Measures Pumps and generators used for dewatering and water control shall be quiet equipment enclosed in sound deadening devices. B. Surface Water Control: Surface water control generally falls in to the following categories: 1. Normal low flows along the channel; 2. Storm/flood flows along the channel; 3. Flows from existing storm drain pipelines; and, 4. Local surface inflows not conveyed by pipelines. The CONTRACTOR shall coordinate, evaluate, design, construct, and maintain temporary water conveyance systems. These systems shall not worsen flooding, alter major flow paths, or worsen flow characteristics during construction. The CONTRACTOR is responsible to ensure that any such worsening of flooding does not occur. The CONTRACTOR is solely responsible for determining the methods and adequacy of water control measures. At a minimum, the CONTRACTOR will be responsible for diverting the quantity of surface flow around the construction area so that the excavations will remain free of surface water for the time it takes to install these materials, and the time required for curing of any concrete or grout. The CONTRACTOR is cautioned that the minimum quantity of water to be diverted is for erosion control and construction purposes and not for general protection of the construction-site. It shall be the CONTRACTOR's responsibility to determine the quantity of water which shall be diverted to protect his work from damage caused by storm water. The CONTRACTOR shall, at all times, maintain a flow path for all channels. Temporary structures such as berms, sandbags, pipeline diversions, etc., may be permitted for the control of channel flow, as long as such measures are not a major obstruction to flood flows, do not worsen flooding, or alter historic flow routes. C. Groundwater Control: The CONTRACTOR shall install adequate measures to maintain the level of groundwater below the foundation subgrade elevation and maintain sufficient bearing capacity for all structures, pipelines, earthwork, and rock work. Such measures may include, but are not limited to, installation of perimeter subdrains, pumping from drilled holes or by pumping from sumps excavated below the subgrade elevation. The foundation bearing surfaces are to be kept dewatered and stable until the structures or other types of work are complete and backfilled. Disturbance of foundation subgrade by CONTRACTOR operations shall not be considered as originally unsuitable foundation subgrade and shall be repaired at CONTRACTOR’s expense. Any temporary dewatering trenches or well points shall be restored following dewatering operations to reduce permeability in those areas as approved by the ENGINEER. CONTRACTOR is to restore any areas disturbed by the dewatering operations to their original condition. LPATH Berm Erosion 02240-3 Water Control and Dewatering Protection Measures D.

Final topography and/or cross-sections will be surveyed of areas that are to finished grade and compared to the design section for accuracy. Final grade shall match design grades within the tolerances discussed in PART 3 EXECUTION. PART 2 PRODUCTS 2.01 MATERIALS A. Embankment material may consist of approved material acquired from excavations or material hauled from outside the project limits. Suitable material identified on-site shall be used first for embankments and backfill. Excess excavated native soils which are not used as embankment or backfill shall become the property of the CONTRACTOR and shall be disposed of off-site by the CONTRACTOR, in a location acceptable to the ENGINEER. B. Muck excavation encountered in all areas shall also include the replacement of excavated muck with uniformly graded rock, riprap, on-site or imported soils, or other material whichever is most suitable for the specific situation encountered. The ENGINEER will determine which type of aggregate or other material which shall be used after observing the specific site conditions. PART 3 EXECUTION 3.01 GENERAL EXCAVATION/EMBANKMENT A. General: The excavation and embankment for the project work shall be finished to reasonably smooth and uniform surfaces. Variation from the subgrade plane shall not be more than .08 feet in soil or more than .08 feet above or .50 below in rock. Where bituminous or concrete surfacing materials are to be placed directly on the subgrade, the subgrade plane shall not vary more than 0.04 feet. Materials shall not be wasted without permission of the ENGINEER. Excavation operations shall be conducted so that material outside of the limits of slopes will not be disturbed. Prior to beginning grading operations in any area, all necessary clearing and grubbing in that area shall have been performed in accordance with Section 02230 of these Specifications. When the CONTRACTOR’s excavating operations encounter remains of pre-historic people’s dwelling sites or artifacts of historical or archaeological significance, the operations, shall be temporarily discontinued. The ENGINEER will contact archaeological authorities to determine the disposition thereof. When directed, the CONTRACTOR shall excavate the site in such a manner as to preserve the artifacts encountered and shall remove them for delivery to the custody of the proper state authorities. Such excavation will be considered and paid for as extra work. B. Excavation: 1. Unclassified: All excess suitable material excavated from the project site and not used for embankment shall be removed from the project site and become the property of the CONTRACTOR. Where material encountered LPATH Berm Erosion 02315-3 Excavation and Embankment Protection Measures within the limit of the work is considered unsuitable for embankment (fills) on any portion of this project work, such material shall be excavated as directed by the ENGINEER and replaced with suitable fill material. All unsuitable excavated material from excavation consisting of any type of debris (surface or buried), excavated rock, bedrock or rocks larger than 6 inches in diameter and boulders shall be hauled from the project site and disposed of. Debris is defined as “anything that is not earth which exists at the job site”. 2 . Muck: Where excavation to the finished grade section results in a subgrade or slopes of unsuitable soil, the ENGINEER may require the CONTRACTOR to remove the unsuitable materials and backfill to the finished graded section with approved material. Disposal of the material shall be at the CONTRACTOR’s expense. Good surface drainage shall be provided around all permanent cuts to direct surface runoff away from the cut face. 3. Rock: Unless otherwise specified, rock shall be excavated to a minimum depth of 0.5 feet below subgrade within the limits of the channel area, and the excavation shall be backfilled with material shown on the Drawings or as designated by the ENGINEER. Disposal of material and replacement with suitable approved material shall be at the CONTRACTOR’s expense. C. Embankment Construction: Embankment construction shall consist of constructing all fill areas, including preparation of the areas upon which they are to be placed, and the placing and compacting of embankment material in holes, pits and other depressions within the project area. Only approved materials shall be used in the construction of embankments and backfills. Approved materials shall consist of clean on-site cohesive soils or approved imported soils. On-site cohesive soils are suitable for use as compacted fill provided the following recommendations are met: Percent Finer by Weight Gradation (ASTM C136) ½-Inch 100 3/8-Inch 70 – 100 No. 4 Sieve 50 – 100 No. 200 Sieve 60 (min) • Liquid Limit 35 (max) • Plasticity Index 20 (max) • In-Situ Coefficient of Permeability 1x10-6 cm/sec Excavation and Embankment will only be paid when a significant change in grade is required, as determined by the ENGINEER. Minor cuts and fills will be considered incidental to the work, and will not be paid for separately under this section. LPATH Berm Erosion 02315-4 Excavation and Embankment Protection Measures On-site cohesive soils or imported soils should be placed and compacted in horizontal lifts, using equipment and procedures that will produce recommended moisture contents and densities throughout the lift and embankment height. On-site or imported cohesive soils should be compacted within a moisture content range of 2% below, to 2% above optimum moisture content and compacted to 95% of the Maximum Standard Proctor Density (ASTM D698). When embankment is to be placed and compacted on hillsides, or when new embankment is to be compacted against existing embankments, or when embankment is built 1/2 width at a time, the slopes that are steeper than 4:1 when measured longitudinally or at right angles to the adjacent ground shall be continuously benched over those areas where it is required as the work is brought up in layers. Benching shall be well keyed and where practical a minimum of 8 feet. Each horizontal cut shall begin at the intersection of the original ground and the vertical sides of the previous cuts. Material thus cut out shall be recompacted along with the new embankment material at the CONTRACTOR’s expense. The ground surface underlying all fills shall be carefully prepared by removing all organic matter, scarification to a depth of 8 inches and recompacting to 95% of the Maximum Standard Proctor Density (ASTM D698) at optimum moisture content + or - 2% prior to fill placement. Embankment material shall be placed in horizontal layers not exceeding 8 inches (loose measurement) and shall be compacted to 95% of the Maximum Standard Proctor Density (ASTM D698) at optimum moisture content + or - 2%. Effective spreading equipment shall be used on each lift to obtain uniform thickness prior to compacting. As the compaction of each layer progresses, continuous leveling and manipulating will be required to assure uniform density. For embankments which serve as berms, the downstream portion shall be “keyed” into the subsurface soils a minimum of 3 feet to enhance the stability of the slope. Materials which are removed from excavations beneath the water table may be over the optimum moisture content and will require that they be dried out prior to reusing them. Cross hauling or other action as appropriate will be ordered when necessary to insure that the best available material is placed in critical areas of embankments, including the top 2 feet of all embankments. No additional payment will be made for cross hauling ordered by the ENGINEER. Frozen materials shall not be used in construction of embankments. During the construction of channels, the channel bottom shall be maintained in such condition that it will be well drained at all times. Excavation or Embankment (Fill), and Structural Backfill work either completed or in a stage of completion that is either eroded or washed away or becomes unstable due to either rains, snow, snow melt, channel flows or lack of proper water control shall be either removed and replaced, recompacted or reshaped as directed by the LPATH Berm Erosion 02315-5 Excavation and Embankment Protection Measures ENGINEER and in accordance with the Drawings and Specifications at the CONTRACTOR’s sole expense. Removed unsuitable materials shall be hauled away and disposed of at the CONTRACTOR’s expense. Placing of replacement materials for removed unsuitable materials shall be purchased, placed and compacted at the CONTRACTOR’ expense. D. Proof rolling with a heavy rubber tired roller will be required, if designated on the Drawings or when ordered by the ENGINEER. Proof rolling shall be done after specified compaction has been obtained. Areas found to be weak and those areas which failed shall be ripped, scarified, wetted if necessary, and recompacted to the requirements for density and moisture at the CONTRACTOR’s expense. Proof rolling shall be done with equipment and in a manner acceptable to the ENGINEER. Proof rolling as shown on the Drawings or as ordered by the ENGINEER shall not be measured and paid for separately, but shall be included in the unit prices bid for the work. 3.02 EXCAVATION AND BACKFILL FOR STRUCTURES A. Poor foundation material for any of the work shall be removed, by the CONTRACTOR, as directed by the ENGINEER. The CONTRACTOR will be compensated for removal and replacement of such materials in accordance with Muck Excavation. The CONTRACTOR is cautioned that construction equipment may cause the natural soils to pump or deform while performing excavation work inside and on footings, structural floor slabs, or other structure foundation areas. Foundation materials which are: a) saturated by either surface or subsurface flows due to the lack of adequate water control or dewatering work by the CONTRACTOR; b) frozen for any reason; or, c) that are disturbed by the CONTRACTOR’s work or caused to become unacceptable for foundation material purposes by means of the CONTRACTOR’s equipment, manpower, or methods of work shall be removed and replaced by the CONTRACTOR at his expense. Dewatering should not be conducted by pumping from inside footing, structural floor slab, or other structure foundation limits. This may decrease the supporting capacity of the soils. Care should be taken when excavating the foundations to avoid disturbing the supporting materials. Excavation by either hand or careful backhoe soil removal, may be required in excavating the last few inches of material to obtain the subgrade of any item of the concrete work. Any over-excavated subgrades that are due to the CONTRACTOR’s actions, shall be brought back to subgrade elevations by the CONTRACTOR and at his expense in the following manner: LPATH Berm Erosion 02315-6 Excavation and Embankment Protection Measures 1. For over-excavations of 2 inches or less, either: Backfill and compact with an approved granular materials; backfill with 1/2 inch crushed rock; or fill within concrete at the time of the appurtenant structure concrete pour. 2. For over-excavations greater than 2 inches, backfill and compact with an approved granular material. All granular footings, structural floor slabs, or other structure areas shall be compacted with a vibratory plate compactor prior to placement of concrete, reinforcing, or bedding materials. B. Backfill, and fill within 2 feet of and adjacent to all structures and for full height of the walls, shall be selected non-swelling material. It shall be granular, well graded, and free from stones larger than 3 inches. Material may be job excavated, but selectivity will be required as determined by the ENGINEER. Refer to the Drawings for job specific requirements. Stockpiled material, other than topsoil from the excavation shall be used for backfilling unless an impervious structural backfill is specified. The backfill material shall consist of either clean on-site granular materials free of stones larger than 3 inches in diameter with no more than 20% passing the No. 200 sieve, or equivalent imported materials. All backfill around the structures shall be consolidated by mechanical tamping. The material shall be placed in 8-inch loose lifts within a range of 2% above to 2% below the optimum moisture content and compacted to 95% of Maximum Standard Proctor Density (ASTM D698) for cohesive soils, or to 70% relative density for pervious material as determined by the relative density of cohesionless soils test, ASTM D4253. When specified on the Drawings or as required by the ENGINEER, Class I structural backfill shall meet the following gradation requirements: % by Weight Passing Sieve Size Square Mesh Sieves 2-Inch 100 No. 4 30 - 100 No. 50 10 – 60 No. 200 5 – 20 In addition, this material shall have a liquid limit not exceeding 35 and a plasticity index of not over 6.

Perimeter controls include, but are not limited to, a vegetated buffer strip around the lower perimeter of the land disturbance, sediment barriers such as straw bales and silt fences; sediment basins; or a combination of such measures. Vegetated buffer strips may be used only where runoff in sheet flow is expected and should be at least 20 feet in width. 3.05 TIMING AND STABILIZATION OF SEDMENT AND EROSION CONTROL MEASURES A. Sediment barriers, perimeter dikes, and other measures intended to either trap sediment or prevent runoff from flowing over disturbed areas must be constructed as a first step in grading and be made functional before land disturbance takes place. Earthen structures such as dams, dikes, and diversions must be stabilized within 5 days of installation. Stormwater outlets must also be stabilized prior to any upstream land disturbing activities. 3.06 STABILIZATION OF WATERWAYS AND OUTLETS A. All on-site stormwater conveyance channels used by the CONTRACTOR for temporary erosion control purposes shall be designed and constructed with adequate capacity and protection to prevent erosion during storm and runoff events. Stabilization adequate to prevent erosion shall also be provided at the outlets of all pipes and channels. 3.07 STORM SEWER INLET PROTECTION A. All storm sewer inlets which are made operable during construction or which drain stormwater runoff from a construction site shall be protected from sediment deposition by the use of filters. 3.08 WORKING IN OR CROSSING WATERCOURSES AND WETLANDS A. Construction vehicles should be kept out of watercourses to the extent possible. Where in-channel work is necessary, precautions must be taken to stabilize the work area during construction to minimize erosion. The channel (including bed and banks) must always be restabilized immediately after in-channel work is completed. B. Where a live (wet) watercourse must be crossed by construction vehicles during construction, a temporary crossing must be provided for this purpose. If the crossing involves a pipe or other type of conduit placed in the watercourse, the pipe shall be sized to allow unrestricted passage of all flows anticipated to be carried by the LPATH Berm Erosion 02370-4 Erosion and Sediment Control Protection Measures watercourse. Likewise, installation of a span-type crossing across the watercourse shall be placed so no restriction of anticipated flows occur. 3.09 CONSTRUCTION ACCESS ROUTES A. Wherever construction vehicles enter or leave a construction site, a stabilized construction entrance and Tracking Pad are required. Where sediment is transported onto a public road surface, the roads shall be cleaned thoroughly at the end of each day. Sediment shall be removed from roads by shoveling or sweeping and be transported to a sediment controlled disposal area. Street washing shall be allowed only after sediment is removed in this manner. 3.10 DISPOSITION OF TEMPORARY MEASURES A. All temporary erosion and sediment control measures shall be disposed of within 30 days after final site stabilization is achieved or after the temporary measures are no longer needed as determined by the OWNER. Trapped sediment and other disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion. 3.11 MAINTENANCE A. All temporary and permanent erosion and sediment control practices must be maintained and repaired as needed to assure continued performance of their intended function. 3.12 SEQUENCING A. The CONTRACTOR shall submit a sequencing plan for approval for erosion control in conformance with his overall Construction Plan for approval by the OWNER. Changes to the Erosion Control Sequencing Plan may be considered by the OWNER only if presented in writing by the CONTRACTOR. 3.13 SUBSTANTIAL COMPLETION OF EROSION CONTROL MEASURES A. At the time specified in the Contract Documents, and subject to compliance with specified materials and installation requirements, the CONTRACTOR will receive a Substantial Completion Certificate for temporary erosion control measures. 3.14 MAINTENANCE OF EROSION CONTROL MEASURES AFTER SUBSTANTIAL COMPLETION A. The CONTRACTOR will be responsible for maintaining temporary erosion control measures as specified in the Drawings and Contract Documents until such time as the disturbed drainage area has stabilized as determined by the ENGINEER and the OWNER. 3.15 FINAL COMPLETION AND ACCEPTANCE OF EROSION CONTROL MEASURES A. After the ENGINEER and OWNER have determined that the drainage area has stabilized, the CONTRACTOR shall remove all remaining temporary erosion control LPATH Berm Erosion 02370-5 Erosion and Sediment Control Protection Measures measures. Any damage to the site shall be repaired to the satisfaction of the ENGINEER and at no cost to the OWNER.

The installation site shall be prepared by clearing, grubbing, and excavation or filling the area to the design grade. This includes removal of topsoil and vegetation. LPATH Berm Erosion 02371-5 Geotextile Fabric for Concrete Protection Measures Block Revetment 3.02 INSTALLATION A. The geotextile shall be placed in intimate contact with the soils without wrinkles or folds and anchored on a smooth graded surface approved by the Engineer. The geotextile shall be placed in such a manner that placement of the overlying materials will not excessively stretch so as to tear the geotextile. Anchoring of the terminal ends of the geotextile shall be accomplished through the use of key trenches or aprons at the crest and toe of the slope. B. The geotextile shall be placed with the machine direction parallel to the direction of water flow which is normally parallel to the slope for erosion control runoff and wave action, and parallel to the stream or channel in the case of streambank and channel protection. Adjacent geotextile sheets shall be joined by either sewing or overlapping. Overlapped seams of roll ends shall be a minimum of 300 mm (12 in) except where placed under water. In such instances the overlap shall be a minimum of 1 m (3.28 ft). Overlaps of adjacent rolls shall be a minimum of 300 mm (12 in) in all instances. C. When overlapping, successive sheets of the geotextile shall be overlapped upstream over downstream, and/or upslope over downslope. In cases where wave action or multidirectional flow is anticipated, all seams perpendicular to the direction of flow shall be sewn. D. Care shall be taken during installation so as to avoid damage occurring to the geotextile as a result of the installation process. Should the geotextile be damaged during installation, a geotextile patch shall be placed over the damaged area extending 1 m (3.28 ft) beyond the perimeter of the damage. E. The armor system placement shall begin at the toe and proceed up the slope. Placement shall take place so as to avoid stretching and subsequent tearing of the geotextile. Riprap and heavy stone filling shall not be dropped from a height of more than 300 mm (12 in). Stone with a mass of more than 100 kg (220 lbm) shall not be allowed to roll down the slope. F. Slope protection and smaller sizes of stone filling shall not be dropped from a height exceeding 1 m (3.28 ft), or a demonstration provided showing that the placement procedures will not damage the geotextile. In underwater applications, the geotextile and backfill material shall be placed the same day. All void spaces in the armor stone shall be backfilled with small stone to ensure full coverage. G. Following placement of the armor stone, grading of the slope shall not be permitted if the grading results in movement of the stone directly above the geotextile. H. Field monitoring shall be performed to verify that the armor system placement does not damage the geotextile. I. Any geotextile damaged during backfill placement shall be replaced as directed by the Engineer, at the contractor's expense.

B. Water Reducing, Set-Controlling Admixture: The CONTRACTOR shall use a “mid-range” water reducing, set controlling admixture, Polyheed 997, or equal. The water-reducing admixture shall be used in all concrete and shall conform to ASTM C 494, specifically Types A, B, C, D and E. C. Finely Divided Mineral Admixtures: Mineral admixtures shall be limited to fly ash conforming to ASTM C 618, Class C. 2.05 BATCHING Measuring and batching of materials shall be done at a batching plant. A. Portland Cement: Either sacked or bulk cement may be used. No fraction of a sack of cement shall be used in a batch of concrete unless the cement is weighed. Bulk cement shall be weighed on scales separate and distinct from the aggregate hopper or hoppers. Batching shall be such that the accuracy of batching shall be plus or minus one percent of the required weight. B. Water: Unless water is to be weighed, the water-measuring equipment shall include an auxiliary tank from which the measuring tank shall be filled. In lieu of the volume method, the CONTRACTOR will be permitted to use a water-metering device. C. Aggregates: Aggregates shall be handled from stockpiles or other sources to the batching plant in such a manner as to secure a uniform grading of the material. Aggregates that have become segregated, or mixed with earth or foreign material, shall not be used. Batching shall be so conducted as to result in the weights of material required for each type aggregate within a tolerance of two percent. Free water contents of the coarse and fine aggregates shall be continuously tested LPATH Berm Erosion 03310-6 Structural Concrete Protection Measures and concrete mixture adjusted for moisture conditions of the aggregate in order to meet the designated water/cement ratio. D. Fine Aggregate: The proportion of fine aggregate shall be between 36 and 44 percent by volume of the total aggregates in the concrete. 2.06 MIXING Ready-mixed concrete shall be either “central mixed” or “shrink mixed” concrete as defined in ASTM C 94. “Truck mixed” concrete as defined in ASTM C 94 shall not be permitted. Mixing time shall be measured from the time water is added to the mix, or cement contracts the aggregate. All concrete shall be homogeneous and thoroughly mixed, and there shall be no lumps or evidence of undispersed cement. Mixers and agitators, which have an accumulation of hard concrete or mortar, shall not be used. Ready-mixed concrete shall be mixed and transported in accordance with ASTM C 94. The temperature of mixed concrete, immediately before placing shall not be less than 50°F or more than 80°F for slabs larger than 10,000 square feet and not be less than 50°F or more than 85°F for walls. Aggregates and water shall be heated or cooled as necessary to produce concrete within these temperature limits. Neither aggregates nor mixing water shall be heated to exceed 150°F. The time elapsing from the time water is added to the mix (or the cement comes in contact with aggregate) until the concrete is deposited in place at the site of the work shall not exceed 45 minutes when the concrete is hauled in non-agitating trucks, nor more than 90 minutes when hauled in truck mixers or truck agitators. The batch shall be so charged into the drum that a portion of the mixing water shall enter in advance of the cement and aggregates. The flow of water shall be uniform and all water shall be in the drum by the end of the first 1/4 of the specified mixing time. Cement shall be charged into the mixer by means that will not result in loss of cement due to the effect of wind, or in accumulation of cement on surfaces of hoppers or in other conditions which reduce or vary the required quantity of cement in the concrete mixture. 2.07 TRANSPORTING MIXED CONCRETE - MIXED CONCRETE OR TRUCK MIXERS Transporting of mixed concrete shall conform to ASTM C 94. Truck agitators shall be loaded not to exceed the manufacturer's guaranteed capacity. They shall maintain the mixed concrete in a thoroughly mixed and uniform mass during hauling. No additional mixing water shall be incorporated into the concrete during hauling or after arrival at the delivery point, unless approved. If additional water is to be incorporated into the concrete at the site, the drum shall be revolved not less than 30 revolutions at mixing speed after the water is added and before discharge is commenced. One addition of water at the site to adjust mix workability is permitted but the maximum water cement ratio shall not be exceeded. LPATH Berm Erosion 03310-7 Structural Concrete Protection Measures The CONTRACTOR shall furnish a water-measuring device in good working condition, mounted on each transit mix truck, for measuring the water added to the mix on the site. All water tanks on transit mix trucks shall be filled prior to being batched and arrive at the construction site 100% full. Each load of ready mixed concrete delivered at the job shall be accompanied by the ticket referencing design mix and showing volume of concrete, the weight of cement in pounds, percent of free water in coarse and dry aggregates, and the total weight of all ingredients in pounds. The ticket shall also show the time of day at which the materials were batched and the reading of the revolution counter at the time the truck mixer is charged. See Paragraph 1.08. 2.08 COMPRESSIVE STRENGTH Concrete compressive strength requirements consist of a minimum strength that must be obtained before various loads of stresses are applied to the concrete and, for concrete designated by strength, a minimum strength at the age of 28 days. Unless otherwise shown on the Drawings, the 28-day compressive strength of structural concrete shall be a minimum of 4,000 psi. The mix shall be designed for required strengths in accordance with ACI 301. The ratio of water to the sum of concrete + pozzolan shall not exceed 0.41 by weight for durable, watertight, concrete. The amount of fly ash in the mix shall be between 15 and 20 percent by weight of the total cementitious materials. 2.09 CONCRETE VIBRATORS Concrete vibrators for consolidating concrete shall be 2 1/2 inch diameter "high cycle" vibrators with a frequency under load of 8,000 - 10,400 vibrations per minute (vpm). Concrete vibrators of lesser capacity are unacceptable for use in any part of the construction. The CONTRACTOR shall have at least one standby concrete vibrator ready for use for every two concrete vibrators in use during a concrete placement. PART 3 EXECUTION 3.01 PRIOR TO PLACEMENT Prior to placing concrete the CONTRACTOR shall remove all debris and thoroughly dampen the surfaces that will be in contact with the concrete to be placed. The CONTRACTOR shall use compressed air from an air-compressor to blow-out construction debris and dirt at the bottom of members to be placed such as walls, beams and columns, prior to final placement of forms that will obscure any joint. The CONTRACTOR shall demonstrate to the ENGINEER that all debris, such as concrete particles, saw dust, loose tie wire, bar tags, tape, trash and dirt, have been thoroughly removed. No concrete shall be placed when form surfaces that will be in contact with the concrete, LPATH Berm Erosion 03310-8 Structural Concrete Protection Measures reinforcement, embedded items or sub-base is less than 32°F. When the mean daily outdoor temperature is less than 40°F, the temperature of the concrete shall be maintained between 50°F and 70°F for the required curing period. When necessary, arrangements for heating, covering, insulating, or housing the concrete work shall be made in advance of placement and shall be adequate to maintain the required temperature without injury due to concentration of heat. Combustion heaters shall not be used during the first 24 hours unless precautions are taken to prevent exposure of the concrete to exhaust gases which contain carbon dioxide. Concrete shall not be placed against forms exposed to heating by the unless the temperature of the forms is first cooled to ≤ 90°F. 3.02 PLACEMENT Placement shall conform to ACI 301, Chapter 8 "Placing", ACI 304R, "Guide of Measuring, Mixing, Transporting and Placing Concrete," ACI 306 "Recommended Practice for Cold Weather Concreting", ACI 305 "Recommended Practice for Hot Weather Concreting" and ACI 309, "Standard Practice for Consolidation of Concrete". No concrete shall be placed until all formwork, reinforcement, installation of parts to be embedded, bracing of forms, and preparation of surfaces involved in the placing have been reviewed by the ENGINEER. No concrete shall be placed in water except with the written permission of the ENGINEER. All surfaces of forms and embedded materials that have become encrusted with dried mortar or grout from concrete previously placed shall be cleaned of all such mortar or grout before the surrounding or adjacent concrete is placed. Immediately before placing concrete, all surfaces upon or against which the concrete is to be placed shall be free from standing water, mud, debris or loose materials. The surfaces of absorptive materials against or upon which concrete is to be placed shall be moistened thoroughly so that moisture will not be drawn from the freshly placed concrete. The concrete shall be placed by equipment that will prevent segregation or loss of ingredients. The stream of concrete shall not be allowed to separate by permitting it to fall freely over rods, spacers or other embedded materials. No wetting of concrete surfaces during slab finishing operations shall be permitted. Further, no concrete finishing operation shall be permitted while there is water on the surface of slabs and other flatwork. Unless otherwise called out in these Specifications or shown in the Drawings, the placement lift depth of concrete in walls shall be limited to two feet or less to minimize surface defects such as air voids that can form on concrete surfaces. Lift depths will be limited to one foot if, in the opinion of the ENGINEER, the quality of the finish is unacceptable at the 2-foot lift depth. 3.03 CONSOLIDATION All concrete shall be thoroughly consolidated with internal vibrators as recommended in ACI 309 immediately after deposition. The concrete shall be thoroughly worked around the reinforcing steel, around embedded items and into corners of forms. Vibration shall be supplemented by spading, rodding or forking to eliminate all honeycomb and voids around embedded items. The vibrator shall be inserted vertically, allowing it to penetrate rapidly to the bottom of the lift and at least six inches into the previous lift. The vibrator shall be held at the bottom of LPATH Berm Erosion 03310-9 Structural Concrete Protection Measures lift for 5 to 15 seconds. The vibrator shall be pulled up at a rate of about three inches per second. The vibrator shall be inserted so that the fields of action overlap. The field of action is approximately eight times the vibrator’s head diameter. Thus for a 2 1/2 inch diameter vibrator, the spacing of each insertion will be approximately 20 inches. Vibration shall be stopped when the concrete surface takes a sheen and large air bubbles no longer escape. Do not use a vibrator to move concrete horizontally. 3.04 OPENINGS AND INSERTS Pipe sleeves, inserts for pipe connections, anchors and forms for pipe holes must be accurately placed and securely fastened to the forms in such a manner that the placing of concrete will not alter their alignment or location. In the event that openings are inadvertently omitted or improperly placed, the ENGINEER may require the concrete to be cored at the proper location. Filling of improperly placed openings shall be done with expansive grout or dry pack or mortar applied with an accepted epoxy adhesive. The surfaces of the opening shall be roughened prior to filling. 3.05 EMBEDDED ITEMS At the time of concrete placement, embedded items should be clean and free from mud, oil and other coatings that may adversely affect bonding capacity. Aluminum embedments shall be coated with a bituminous material to prevent electrolytic action between the embedded item and reinforcing steel that results in concrete deterioration. Embedment items shall be accurately placed and securely fastened to the forms in such a manner that the placing of concrete will not alter their alignment or location. Contact between embedded items and reinforcing steel or tendon ducts is unacceptable and is not permitted. 3.06 CONSTRUCTION JOINTS The location of all construction joints will be subject to the acceptance of the ENGINEER. The surface of all construction joints shall be thoroughly cleaned and all laitance and standing water removed. Clean aggregate shall be exposed by abrasive blast cleaning. Wire brushing and air water jets may be used while concrete is fresh provided results are equal to abrasive blast cleaning. Construction joints shall be keyed at right angle to the direction of shear. Except where otherwise shown on the Drawings, keyways shall be at least 1-1/2" in depth over at least 25% of the area of the section. 3.07 EVAPORATIVE RETARDANT The use of an evaporative retardant is required to assist in proper placement of concrete. See Section 03390. When an evaporative retardant is used, it shall be applied two times: after screeding and after the first floating operation. The retardant should be applied at a rate of one gallon of sprayable solution per 200 - 400 square feet by spraying with an industrial type sprayer. If the nozzle of the sprayer becomes plugged, the CONTRACTOR shall clean, or replace, the nozzle. Under no circumstances shall the retardant be used except by spraying a LPATH Berm Erosion 03310-10 Structural Concrete Protection Measures mist with a nozzle. The retardant shall be applied in strict conformance with the manufacturer’s recommendations and precautions. In no case shall the retardant be used as a finishing agent. The use of an evaporative retardant requires review and approval by the ENGINEER.

White Portland Cement shall be substituted for a part of the gray Portland Cement on exposed concrete in order to produce a color matching the color of the surrounding concrete, as determined by a trial patch. The quantity of mixing water shall be no more than necessary for handling and placing. The patching mortar shall be mixed in advance and allowed to stand with frequent manipulation with a trowel, without addition of water, until it has reached the stiffest consistency that will permit placing. 2.07 WATER Only clean potable water shall be used. A calibrated measuring device is required for measuring the proper amount of water to be added to pre-packaged grouts and mortars. PART 3 EXECUTION 3.01 REPAIR OF SURFACE DEFECTS Surface defects, unless otherwise specified by the Contract Documents, shall be repaired immediately after form removal but not before review by the ENGINEER. The surface temperature of the concrete shall be 50° F and rising. The CONTRACTOR shall measure surface temperatures when requested by the ENGINEER. If necessary the CONTRACTOR shall enclose and heat the area to be repaired to bring the surface temperature of the concrete and air temperature to acceptable levels and to permit proper curing. All honeycombed and other defective concrete shall be removed down to sound concrete. If chipping is necessary, the edges shall be perpendicular to the surface or slightly undercut. Feathered edges will not be permitted. The area to be patched and an area at least six inches wide surrounding it shall be dampened to prevent absorption of water from the patching mortar. A bonding grout shall be prepared, mixed to the consistency of thick cream, and after surface water has evaporated from the area to be patched, well brushed into the surface. LPATH Berm Erosion 03350-4 Concrete Finishing Protection Measures When the bond coat begins to lose the water sheen, the premixed patching mortar shall be applied. The mortar shall be thoroughly consolidated into place and struck off so as to leave the patch slightly higher than the surrounding surface. To permit initial shrinkage, it shall be left undisturbed for at least one hour before being finally finished. The patched area shall be kept damp for seven days. Metal tools shall not be used in finishing a patch in a formed wall that will be exposed. 3.02 TIE HOLES A. Water Retaining Structures and Below Grade Vaults with Breakback Cone Ties Fill tie holes solid as specified in Section 03615. B. Other Structures After being cleaned and thoroughly dampened, fill tie holes solid as specified in Section 03615. 3.03 PROPRIETARY MATERIALS Certain types of defects may require the use proprietary compounds for adhesion or as patching ingredients. The ENGINEER will review these defects and request means and methods for these repairs from the CONTRACTOR. In lieu of, or in addition to, the foregoing patching procedures using bond coat and patching mortars, epoxy bonding agents and premixed pre-packaged grouts may be used for repair of defective areas. Such compounds shall be used in accordance with the manufacturer's written recommendations and directions. The ENGINEER shall review and provide written acceptance of these procedures. 3.04 FINISHING OF FORMED AND UNFORMED SURFACES Finishes shall be performed as called out in the Drawings and in referenced Specifications.

The evaporative retardant shall not be applied during the final steel troweling operations or after the water sheen has disappeared from the concrete surface. 3.03 SLABS For concrete surfaces not in contact with forms, a procedure determined by the ENGINEER shall be applied immediately after completion of placement and finishing. 3.04 WALLS AND COLUMNS Moisture loss from surfaces placed against wooden or metal forms exposed to heating by the sun shall be minimized by keeping the forms wet until they can be safely removed. After form removal, the concrete shall be cured until the end of the curing time by one of the previously described curing methods. Concrete shall not be placed against forms that have been exposed to air below freezing temperatures until the forms have been heated so that the surface temperature of the form is ≥ 40° F. The top of walls and columns not covered by forms shall be cured using a membrane-curing compound conforming to ASTM C 309 immediately after placement 3.05 OTHER SURFACES Unless otherwise shown in the Drawings all other surfaces shall be cured using two applications of a membrane-curing compound conforming to ASTM C 309. The second application shall be applied at 90° to the first application. 3.06 COLD WEATHER Curing during cold weather conditions shall include the above methods except for water cure unless measures are taken to prevent freezing of the water. 3.07 HOT WEATHER If the rate of evaporation approaches 0.2 lb/ft2 /hr, as estimated by ACI 305, precautions against plastic shrinkage cracking are required. The CONTRACTOR shall have a recording LPATH Berm Erosion 03390-4 Concrete Curing Protection Measures thermometer, hygrometer and wind gage on site seven days prior to first concrete placement. When necessary, provision for windbreaks, shading, fog spraying, sprinkling, ponding, or wet covering with a light colored material shall be made in advance of placement, and such protective measures shall be taken as quickly as concrete hardening and finishing operations will allow. Precautions against plastic shrinkage cracks may be required in conditions other than what is normally considered hot weather conditions. 3.08 RATE OF TEMPERATURE CHANGE Changes in temperature of the air immediately adjacent to the concrete during and immediately following the curing period shall be kept as uniform as possible and shall not exceed 5° F in any one hour or 50° F in any 24-hour period. 3.09 PROTECTION FROM MECHANICAL INJURY During the curing period, the concrete shall be protected from damaging mechanical disturbances, such as load stresses, heavy shock, and excessive vibration. All finished concrete surfaces shall be protected from damage by construction equipment, materials, or methods, by application of curing procedures, and by rain or running water. Self-supporting structures shall not be loaded in such a way as to overstress the concrete.

PART 3 EXECUTION 3.01 GENERAL These grouts contain admixtures that increase grout strength and workability. The strength and performance of the grout is dependent on proper surface preparation, grout mixing and curing. The Contractor shall be required to use a calibrated measuring device to add clean potable water to the grout mix. Water added to a grout mix without a calibrated device is cause for grout rejection, removal and re-placement. Curing is critical to prevent shrinkage cracks that can develop with grouts containing some admixtures. Curing shall begin immediately after placement. All mixing, surface preparation, handling, placing, consolidation, and other means of execu- tion for pre-packaged mortars shall be done according to the instructions and recommenda- tions of the manufacturer and this Specification. In the event that a conflict occurs between this Specification and manufacturer’s instructions, the manufacturer’s instructions shall pre- vail in all cases.
