<br />Contractors, or other entities or persons at the project site.
<br />SHOP DRAWINGS AND SUBMITTALS
<br />SHOP DRAWING & SUBMITTAL REVIEW (including Deferred Structural Components)
<br />The contractor must review and stamp the shop drawings & submittals for review. SER will only review
<br />submittals for items shown on SER documents. Submittals for Deferred Structural Components will receive
<br />cursory review by SER for loads imposed on primary structure. SER will review shop drawings for general
<br />conformance with design concept of the project and general compliance with the information given in the
<br />Structural Contract Documents. Review of submittals does not constitute approval or acceptance of
<br />unauthorized deviation from Contract Documents.
<br />Corrections or comments made on shop drawings during this review do not relieve Contractor from
<br />compliance with the requirements of the plans and specifications.
<br />Contractor responsible for:
<br />• Reviewing, approving, stamping and signing submittals prior to submittal to Architect and SER
<br />• Timing submittals to allow two weeks of review time for the SER and time for corrections and/or
<br />resubmittal

<br />• Verifying information to be confirmed or coordinated
<br />Information solely for fabrication, safety, means, methods, techniques and sequences of construction
<br />Coordination of all trades
<br />Resubmittals shall be clouded and dated for all changes to the submittal. Only clouded portions of
<br />resubmittal will be reviewed and SER's review stamp applies to only these areas.
<br />SUBSTITUTIONS
<br />Substitutions shall be submitted in writing prior to submittal of shop drawings. Shop drawings bearing
<br />substitutions will be rejected. Submit engineering data to substantiate the equivalence of the proposed
<br />items. The SER's basic services contract does not include review of substitutions that require re -
<br />engineering of the item or adjacent structure. Nor does the SER's contract cover excessive review of
<br />proposed substitutions. The fees for making these reviews and/or redesign shall be paid by the
<br />Contractor. Reviews and approvals shall not be made until authorization is received.
<br />SUBMITTALS
<br />Shop drawings and material submittals shall be submitted to the Architect and SER prior to any fabrication
<br />or construction for the following structural items. Submittals shall include one reproducible and one copy,
<br />reproducible will be marked and returned. If deviations, discrepancies, or conflicts between shop drawings

<br />NEW 7- 7 7 STORE EVERETT; WA
<br />prepared by SOUTHSOUND GEOTECHNICAL CONSULTING (SEPTEMBER 18, 2018)
<br />Contractor shall be familiar with recommendations in the above -mentioned report prior to start of
<br />construction. Allowable soil pressure and lateral earth pressure are assumed and therefore must be verified
<br />by a Geotechnical Inspector or the building official. If soils are found to be other than assumed, notify the
<br />Structural Engineer for possible foundation redesign. For wet weather work, see the Geotechnical Report.
<br />Unless noted otherwise, footings shall be centered below columns or walls
<br />INSPECTIONS
<br />All prepared soil -bearing surfaces shall be inspected by the owners Geotechnical Inspector (or building
<br />official) prior to placement of reinforcing steel and concrete. Inspections shall be made per IBC Table
<br />1705.6.
<br />BEARING VALUES
<br />All footings shall bear on undisturbed soil and shall be lowered to firm bearing if suitable soil is not found
<br />at elevations shown. Exterior footings shall bear a minimum of 18" below the finished ground surface.
<br />Footing elevations shown on plans (or in details) are minimum depths and for guidance only; the actual
<br />elevations of footings must be established by the Contractor in the field working with the Geotechnical
<br />Inspector.
<br />Allowable vertical bearing soil pressure = 2,500 psf
<br />Allowable lateral passive resistance = 300 psf/ft
<br />Allowable coefficient of friction = 0.35
<br />SUBGRADE PREPARATION
<br />Prepare subgrade per the Geotechnical Report, summarized as follows: All footings shall be cast on
<br />undisturbed firm natural soils that are free of organic materials. Footing excavation shall be free of loose
<br />soils, sloughs, debris and free of water at all times. If organic silt and/or fill material is encountered at
<br />subgrade elevations, overexcavate a minimum of 2'-0" below the design foundation subgrade elevation
<br />prior to placing footings. The overexcavated areas shall be backfilled with structural fill compacted to 95%
<br />proctor per ASTM D-1557 or a lean concrete mix.
<br />EXISTING UTILITIES
<br />The Contractor shall determine the location of all adjacent underground utilities prior to any excavation,
<br />shoring, pile driving, or pier drilling. Any utility information shown on the plans and details are approximate
<br />and not verified by the SER. Contractor is to provide protection of any utilities or underground structures
<br />during construction.
<br />DRAINAGE
<br />Drainage systems, including foundation, roof and surface drains, shall be installed as directed by the
<br />Geotechnical Report. Vapor retarder placed below slab -on -grade shall conform to ASTM E 1643 and ASTM
<br />E 745.
