POST CONSTRDC'I ION SITE RESTORATION: Unless specifically agreed upon otherwise, the property owner is responsible for final grading of the areas which settle after construction. Prior to awarding the conU'act, the homeowner should communicate to the conlractor any expectations regarding, but not limited to post construction site clean-up, re-landscaping, and restoration of any asphalt, fences, ~ees, decks, ect. that are effected by the construction. All mound type drainfi¢Ids are required by the MOA to be re-vegetated. Thc property owner is responsible for this work unless other arrangements arc made with the contractor. If the property is being sold, the property owner shall ensure that the aforementioned items are ad~essed] with the buyer, and, if the work is to be completed after the sale of the property, that necessary funds are[ escrowed to fund the completion of the work. 9. PROPERTY OWNER INSTALLATION OF SEPTIC SYSTEM: If the property owner intends to install the septic system he/sha must fwst have obtained approval from the Municipality of Anchorage, DSD (343-7904). Homeowner installations typically require more time for engineer inspections. The homeowner should discuss the additional costs associated with such inspections with the engineer prior to starting the project. 10. ENGINEER CHARGES TO INSPECT THE INSTALLATION: The proper~d owner is responsible for payment of all the engineer inspection charges. These charges are in addition to the soils testing and design work that was required to obtain the MOA sewer/well permit. The number of inspections will vary depending on the actual field conditions encountered and the const~'uctinn methods used. If lhere are any questions by the proper~ owner, or his/her representative, regarding charges for installation inspections they should be discussed prior to beginning constzuction. AWWC, Inc. will provide you with a written copy of the fee schedule. 11. CtlANGES IN TIIE SCOPE OF WORK: See Section V, "Disclaimers" regarding design changes. See "Contractor Responsibilities", paragraphs I, 2, & 13. In addition, see "Engineer Responsibilities", paragraphs 2, 4, & 5. · Contractor Responsibilities: 1. PRE-CONSTRUCTION LAYOUT: The contractor is responsible for locating all buried utilities, easements, property lines, surface water setbacks, well radii, and water service lines which may be encroached upon by the proposed septic system. The contractor shall ensure that all setbacks are flagged by a registered land surveyor, or other appropriate means, prior to construction. AWWC, Inc. field engineers/inspectors will not be responsible for establishing or con£u'ming any of the aforementioned setbacks. The contractor should recognize that thc location of all wells, surface waters, structures, and other items] shown on thc des gn drawings are typically derived from as-built surveys, and municipal records. Thc as-[ Page 2 of 7 ,4 ~WWC, Inc., Year 2001 built surveys and municipal records (prepared by professional engineers & land surveyors) have been assumed to be accurate for purposes of this design; however, the accuracy has ~ot necessarily been field verified. Prior to beginning any construction the conWaetor shall field locate all items which have protective setbacks and verify that there are no encroachment concerns. Any encroachments, for which waivers have not been granted, should immediately be brought to the attention of the property owner (or their representative) and the engineer. The test hole pipes shall not be removed/abandoned until after the engineer has established their location relative the new drainfield during the f~t inspection of the drainfield installation or during the pre- constx'uction layout. The new drainfield/s must be within a 30 foot radius of the test hole/s used for establishing the design criteria. The contxactor should establish the elevation of all existing and proposed system components prior to starting construction so as to insure that the necessary grades can be maintained. This is particularly significant when the elevation of the existing system components is unknown because clean-outs are not present, buried, or non-funational (can't measure down them because of obstructions). It is recognized that conditions can be discovered that will materially change the design and the construction costs. 2. DISCREPANCIES BETWEEN DESIGN DRAWINGS AND SPECIFICATIONS: Constmctiun shall be in accordance with the approved site plan and design drawings, and any special provisions noted on the municipal sewer permit. The contractor is respons~le for notifying the engineer of any discrepancies noted on the design plans or drawings, prior to starting work. 3. CHECK GROUNDWATER LEVELS IN TEST 1tOLE MONITORING TUBES: Prior to beginning construction, the con~ctor shall check the liquid level in the test hole monitoring tubes to ensure that there has been no change in the groundwater levels that would impact the proposed design. Any rise in the liquid level should be brought to the attention of the engineer so that design changes can be made if necessary. 4. MAXLMUM DEPTII OF DRAINFIELDS: The maximum depth of the drainfield is shown on the design drawings or is noted in the narrative portion of the design package. The cont~ctor shall notify the engineer of any inconsistencies noted in the design package. For purposes of this installation, the maximum depth of the drainfield will be based upon taking a measurement at the deepest part of the excavation between the highest ground elevation encountered (usually on the uphill side of the excavation) and the bottom of the t~ench or bed excavation. The contractor shall exercise caution not to remove evidence of the original grade prior to establishment of the total system depth. In short, don't remove the organic layer until aRer the original grade elevations are established by the inspecting engineer. 5. SUITABILITY OF MATERIALS USED FOR CONSTRUCTION. The con.actor shall ensure that ~I1 materials being used are in compliance with the most current guidelines established by the Munlcipality of Anchorage. This includes, but is not limited to, the following: a. Drainrock b. Sand filter material for conventional beds, ~enches, or mound systems. c. Sand filter material and pea gravel for Intermittent Sand Filters (ISF). d. Anchorage Sand and Gravel (AS&G) "block pea" material for Upflow Filters. It is recommended that the contractor provide the engineer with current sieve analysis' from the sand/gravel supplier to document the suitability of the material. The engineer assumes no responsibility for ensuring that the materials delivered meet the MOA requirements. 6. BURIAL RATING OF TANKS: The contxactor shall ensure that the septic tank, lift station, or holding tank purchased has a burial depth rating suitable for the actual installation. ?, SEPTIC TANK AND STEP TANK SIZES: Prior to purchasing a septic tank or lift station the contractor shall verify that it is adequately sized for the number of bedrooms shown on the permit issued by MOA. The minimum septic tank size is 1000 gallons and the minimum STEP tank size is 1250 gallons. Page 3 of 7 Inc., Year2001 These size tanks will handle residences with up to 3 bedrooms. For each additional bedroom over three (3) the septic tank or the STEP tank volume shall be increased by a minimum of 250 gallons. For example, a four (4) bedroom residence must have a 1250 gallon septic tank or a 1500 gallon STEP tank. g. INSPECTIONS - ENGINEER NOTIFICATION: The contxactur shall notify the engineer at least 24 hours prior to staring construction. If deemed necessary, a pre-construction site visit shall take place. The contractor shall coordinate with the engineer any inspections which will be required during weekends, holidays, or before/after normal working hours (8:00 am to 5:00 PM). The property owner may Incur additional charges for Inspections which do not occur during normal business hours. It is the contractor's responsibility to notify the engineer a least 2 hours prior to any inspection. 9. REGULATORY NON-COMPLIANCE. The contractor shall report to the engineer and the property owner any observed condition which would put the septic system in violation of State or Municipal regulations. 10. BACKFILL OLD TEST HOLES: Any remaining test hole excavations shall be filled and mounded as part of this pmject. Unless instructed otherwise by the engineer, the old test hole groundwater monitoring pipes shall he removed. 11. FINAL GRADING FOR DRAINAGE: The contractor is responsible for £mal grading so as to ensure that surface nmoff does not adversely effect the septic system constructed, adjacent septic systems, or adjacent structures. 12. SOIL COVER REQUIREMENTS: The contractor shall ensure that the final cover over the tank and drainfield is either compacted adequately when backfilling, or mounded sufficiently to ensure that there is adequate soil cover over the tank and drainfield after settlement occurs. If seasonal conditions prevent this, the property owner (or his representative) shall be notified that additional fill may be required after seRlement occurs. This notification is of extra significance when the property is changing ownership. 13. CHANGES IN CONSTRUL'rrION COSTS: The contractor is responsible for obtaining approval from the property owner for any additional consrmction costs associated with design modifications or changing field conditions prior to doing the work. 14. WORKING IN RIGIIT-OF-WAYS AND TRESPASSING PRIVATE PROPERTY: The contractor is responsible for coordinating (including payment of encroachment permit fees) all access through public and private properties with the appropriate authorities and/or property owners. Furthermore, the contractor shall inform all parties of any potential impacts to adjacent properties prior to beginning any construction. 15. MAINTENANCE & OPERATIONS MANUALS: The comractor shall provide the homeowner with the manufacturer's installation/maintenance manuals for all system components installed under this contract. If not given directly to the property owner, the manuals should be enclosed in a protective cover (plastic bag) and placed/secured in a prominent location so the property owner can fred it. 16. INNOVATIVE SEPTIC SYSTEMS. START-UP INSPECTIONS: The contractor shall notify Anchorage Tank & Welding Company (272-3543) after the installation of an Intermittent Sand Filter kit or Advantex system (supplied by Anchorage Tank) is installed so that the appropriate start-up inspection can be scheduled. This notification also activates the quar~criy maintenance schedule. Such notification is usually not required for BioCycle installations since "BioCycle of Alaska" is typically involved with the installation. The contractor shall contact BioCycle of Alaska (283-9003) regarding any start-up notification requirements. · Well Driller Responsibilities: 1. The well driller shall ensure that he has a well permit in possession prior to drilling the well. 2. The well driller shall physically verify that the there are no septic systems, or other potential sources of contamination, within the protective radius of the proposed well prior to drilling it. Page 4 of 7 Inc., Year 2001 · Engineer Responsibilities: 1. SYSTEM DOCUMENTATION: Thc engineer is responsible for inspecting the installation of the septic system and preparing as-built documentation, to the satisfaction of the M.O.A.. Inspections are performed as necessary to document the construction ofthe system to the satisfaction of the M.O,A. In all cases, inspections shall be performed as necessary to establish the following: * Thc original grades at the drainfield/s site * The bottom of all trench/bed excavation * Top of sand on all sand filters * Top of drainpipe * Septic tank, or lift station, or holding tank prior to backfill * Placement of filter fabric and insulation * After final grading is completed 2. LIMITED AUTIIORITY: The inspecting engineer has no direct authority over the contractors activities or construction/safety practices. Should the engineer identify conditions which dictate a design change, he or she will recommend that work be stopped, and/or the design be modified. If design modifications are necessary, the engineer shall notify the property owner or his/her representative. The inspecting engineer does not have the authority to direct the contractor to modify the system design in such a way that it would be in violation of State or MOA regulations. 3. SEPTIC TANK INTEGRITY: The engineer shall inspect the condition of the existing septic tank and determining its suitability for re-use. If the engineer determines the septic tank to be structurally unsound, it must be replaced. 4. COORDINATION OF DESIGN CtlANGES WI'HI TIlE MOA: If design changes are necessary, the engineer will coordinate the approval of the changes with the MOA. The contractor does not have the authority to proceed with any design modifications until verbal or written approval is obtained from the MOA. 5. COORDINATION OF WAIVERS: If, during cons~uction, it is determined that a waiver will be required in order to install the system as designed, the engineer will apply for the necessary waiver/s to the appropriate State or MOA regulatory bodies. Thc engineering services and State/MOA fees associated with such waivers will be additional charges to the property owner, over and above the installation inspection fees charged by AWWC, Inc. SECTION IV. CONSTRUCTION GUIDELINES: Construction shall be in accordance with the approved site plan and design drawings and any special provisions noted on the municipal well and/or sewer permit. All materials, components, workmanship, and construction practices shafi comply with the Municipality of Anchorage's latest ordinances regarding wells and septic systems, as well as DSD policies. The failure of the inspecting engineer to notice a material or construction non-compliance does not relieve the contractor of his/her responsibility to correct such a ¢¢ficieocv. Septic Tank, Holding Tank, or Lift Station Installation: 1. The burial rating of the tank shall be adequate for the actual burial depth encountered. 2. The tank shall be level and sufficiently bedded to prevent setlling or shifting of the tank. 3. All standpipes on the tank shall extend a minimum of 12 inches above final grade. 4. Tanks installed with less than 4 feet of cover shall be insulated. See "Contractor Responsibilities", paragraph 12 regarding l'mal soil cover. 5. The sewer service line from the house to the tank shall be sloped a minimum of IM" per foot, unless prior approval is obtained from the engineer. Page 5 of 7 Inc., Year 2001 6. The inlet and outlet lines from the tank shall be bedded in drainvock or the soil shall be adequately compacted to prevent future settlement of the soil. 7. A foundation clean-out will be installed ( I-4 feet from the house) if one docs not currently exist. 8. Post tank clean-outs shall be installed per MOA requirements. Does not apply to holding tanks or lift stations with pressurized lines. 9. In high groundwater areas, all tanks shall be anchored to resist buoyancy forces when there is not adequate soil cover to resist the uplift force. Tbe engineer shall make this determination. 10. The £mal soil cover shall be graded so that there is positive drainage away from tank. 11. All holding tanks and lift stations shall have an audible and vis~le alarm inside the residence. 12. All lift stations shall be wh'ed in compliance with all MOA guidelines and the Uniform Electrical Code. A municipal elecu'ical permit and inspections must be obtained in areas where required by the Municipality of Anchorage. 13. The contractor shall remove the old tank, or abandon it in compliance with the Uniform Plumbing Code COPC). The conmactor is solely responsible for the abandonment procedure. 14. 1SF AND ADVANTEX INSTALLATIONS: The conU'ol panel for the Intermittent Sand Filter and Advantex systems shall be located outside the residence, for easy access during inspections. A remote alarm must be installed inside the residence as per DSD requirements. Mounting the panel directly t~ an exterior wood wall should be avoided because the closing of the relays creates a "clanking" noise that may be offensive to the property owners. 15. ISF INSTALLATIONS: The air compressor shall be equipped with 0 to 10 psi gauge for the purpose of monitoring air flow to the sand filter. The pressure gauge will be located so that it is easily monitored by the property owner. · Installation of ConventionalAbsorption Bed & Trenches: 1. Excavate the proposed bed/u'ench to the dimensions shown on the design. The bottom of the excavation shall be within 2 inches of level (2 inch maximum variation between high and Iow spots), If the sidewalls or bottom of the excavation become smeared, they must be raked or scarified before placement of the filter sand or draiurock. 2. The trench or bed should be at least $ feet from the test hole excavation. 3. All soil tests and excavation depths are advisory to the design and are to be verified in the field by the engineer. If design changes are necessary, and the changes effect the contractor charges to the pmpert)r owner, the conUactor shall obtain approval from the property owner prior to proceeding with the work. 4. Once the draiurock is installed, the distribution pipe is to be placed level (0.02 feet difference between high and Iow shots) with the perforations faced downward. Drainrock is then to be placed over the disu'ibution pipe, to provide a minimum of 2 inches of cover over the pipe. The drainrock shall not be pyramided over the drainpipe but shall be the same elevation over the entire trench/bed width. 5. A silt barrier must be installed between the £mal draiurock layer and the native soil backfill. The silt barrier shall cover the entire drainrock surface. 6. Monitor tubes shall be installed at the locations shown on the design drawings, and extend a minimum of 12 inches above final grade. The portion of the monitoring tube extending through the dvainrock shall be perforated from the bottom of the t~ench/bed to the invert of the dism'bution pipe. ?. Backfill over the t'mal dvainrock layer must not be less than 2 feet. Insulation must be installed when the backfill depth is less than 3 feet. The insulation shall cover the entire width of the trencl~ed, the contractor shall "shoot" the final grades to ensure cover depth is adequate, prior to notifying the engineer that the work is complete. The Final cover over the drainfield must graded so that there is no potential for water to pond over the Ixench/drainfield. See "Contractor Responsibilities'; paragraph 12 regarding final soil cover. 8. Ifan alternator valve was installed with this design the contractor shall provide a functional valve key toI the property owner. SECTION V: DISCLAIMERS Page 6 of 7 ~I I~VC, Inc., Year 2001 · UNFORESEEABLE SITE CoNDmoNs: Thc design of this septic system, prepared by AWWC, Inc., was based upon a limited evaluation of the soil, groundwater, and site conditions. The extent of the evaluation is consistent with standard engineering practice in the field. Furthermore, this design was evaluated and approved by the engineers or technicians on staff at the Municipality of Anchorage, DSD, based upon the information provided to them. Occasionally, during conslruction, unforeseeable subsurface conditions (high groundwater, poor soils, buried debris,....) are encountered that make the proposed installation not feas~le. In such cases it is typically necessa~ to do more soils testing, groundwater monitoring, and design work. These additional engineering services will be performed on a fee basis at an hourly rate. AWWC, Inc. will obtain verbal authorization from the property owner (or his/her representative) prior to proceeding with the work, and will provide a written estimate if requested. The property owner should discuss with the contractor any changes in the installation cost associated with the design changes. · IF TIIE PROPERTY BEING SOLD AND FUNDS ESCROWED FOR TIlE UPGRADE, it is important to bear in mind that the ability to upgrade the septic system on this property is not 100% cetiain (for the reasons stated in the previous paragraph). There is always the possibility that conditions could be encountered that would prevent the installation of anything other than a holding tank. Although such a situation would be rare, it is imporiant that all parties recognize that such a scenario is poss~Ic. · SEPTIC SYSTEM PERFORMANCE: Thc design of this septic system is based upon limited soils testing, groundwater monitoring, and a visual assessment. It is possible that the actual soil conditions are less favorable then the testing data indicated and that adverse, unforeseeable, changes in the surface/subsurface water conditions could impact the performance of the system. Numerous other factors, out of the con~'ol AWWC, Inc.. may adversely effect the long term performance of the system. Such factors include, but are not limited to. excessive number of residents in the house, plumbing leaks, the use of septic system additives, failure to pump septic tank regularly, failure to alternate drainfields (when this is an option), or/and excessive usc of water. Given these variables, it is not possible to warrantee the performance ora septic system. IBy proceeding forward with this Installation, the Engineer, Well Driller, Contractor, and Property Owner agree that they have read these specifications and agree to accept the terms and conditions outlined In them.
