The scope of services under this contract is limited to providing a "builder's set" of plans. This set of plans is
<br />sufficient to obtain a building permit; however, all materials and methods of construction necessary to complete the
<br />project are not necessarily described in this "builder's set". The implementation of the plans requires an
<br />Owner/contractor (General Contractor and Subcontractors) thoroughly knowledgeable with the applicable building
<br />codes and methods of construction. The plans and general notes delineate and describe only locations, dimensions,
<br />types of materials and general methods of assembling or fastening. They are not intended to specify particular
<br />products or other methods of any specific material, product or method.
<br />All work shall comply with the most current and stringent requirements of all applicable city, county, state and general
<br />laws, rules, codes, ordinances and regulations and follow all manufacturer's specifications for installation. If the
<br />General Contractor or any Subcontractor performs any work in conflict with the above-mentioned laws, rules, codes,
<br />ordinances and regulations, then the contractor in violation shall bear all costs of repair arising out of the
<br />non-conforming work. See sheet "A0-01" for list of the applicable codes. All codes are subject to local amendments.
<br />The General Contractor and every Subcontractor performing work upon or providing services and/or materials for the
<br />work is required to purchase and maintain in force "All Risk" Builders Risk Insurance prior to commencement of the
<br />work and/or furnishing labor, services and materials. Each "All Risk" policy shall be in an amount sufficient to cover
<br />the replacement value of the work being performed and/or the labor, services, and materials being supplied by the
<br />General Contractor, Subcontractors, Architect, and all professional Consultants
<br />The General Contractor and Subcontractor shall furnish all labor, equipment, and materials necessary to complete
<br />the work indicated on the plans and required by the applicable codes.
<br />No substitutions shall be made without the Owner's written authorization. Any substitution shall be made in advance
<br />to avoid any delay in the project schedule. The General Contractor or any Subcontractor shall not make structural
<br />changes without prior written authorization from the Structural Engineer and approval by the Architect and/or the
<br />Owner
<br />Any addition, deletion, or change in the scope of the work described by the plans and General Notes shall be by
<br />written change order only. The General Contractor shall procure the building official's approval for any change in the
<br />work.
<br />The intent of the plans and general notes is that all labor, materials, equipment, and transportation shall be included
<br />in the work for the complete execution of the project. The Architect shall not be responsible for the means and
<br />methods of construction.
<br />It is the Owner's (General Contractor and all Subcontractors) responsibility prior to or during construction to notify the
<br />Architect in writing of any perceived errors or omissions in the plans and general notes of which a contractor
<br />thoroughly knowledgeable with the building codes and methods of construction should reasonably be aware. Written
<br />instructions addressing such perceived errors or omissions shall be received from the Architect prior to the Owner or
<br />Owner's subcontractors proceeding with the work. The Owner will be responsible for any defects in construction if
<br />these procedures are not followed.
<br />All shop drawings required by the construction documents and general notes shall be submitted to the Architect or
<br />Engineer prior to fabrication for review of compliance with the design concept.
<br />The General Contractor shall be responsible for coordinating the work between the different Subcontractors and
<br />requiring all Subcontractors to use the most current building department approved set of construction documents.
<br />The General Contractor shall arrange a pre-construction meeting to review omissions and discrepancies sufficiently
<br />in advance of construction to assure the orderly progress of the project prior to the performance of any work. All
<br />parties using these construction documents are responsible for reviewing the full content of these drawings for
<br />omissions and discrepancies prior to the start of construction.
<br />The General Contractor and all Subcontractors shall be familiar with the following documents:
<br />a.Most recent Soils report
<br />b.Energy compliance report
<br />c.Structural calculations
<br />d.Acoustical report
<br />The General Contractor shall keep a copy of the above documents and all updates on the site at all times.
<br />The General Contractor shall compare the existing site grades to the grades shown on the plans. Any discrepancy in
<br />elevation from the finished floor to the finished grade at the stairways and walkways shall be communicated to the
<br />Architect for review before proceeding with the work.
<br />All Subcontractors shall perform their own cutting, fitting, and patching of materials in a workmanlike manner, without
<br />causing any damage to or conflict with other subs work.
<br />All trades shall keep the premises clean of any accumulated waste materials and rubbish caused by their work.
<br />Subcontractors shall remove all rubbish, tools, scaffolding, and surplus materials at the completion of the work. All
<br />fixtures, equipment, glazing, floors, and other surfaces shall be left clean and ready for occupancy upon completion
<br />of the project, including sweeping or vacuuming if necessary.
<br />The general notes refer to various professional trade association manuals and publications. The General Contractor
<br />and Subcontractors shall be familiar with and refer to the most recent trade publications relating to their work.
<br />The General Contractor and Subcontractors shall be responsible for storing the materials on the site. The materials
<br />shall be kept secure and protected from moisture, pests, and vandals. Any damages or lost materials arising out of
<br />materials stored on site shall be the responsibility of the General Contractor or Subcontractor who stored the
<br />damaged or lost materials.
<br />The contractor/sub-contractor will use all means necessary to protect the material of their scope of services during
<br />and after installation and to protect the work and materials of all other trades and in the event of damage immediately
<br />make all repairs and replacements necessary to the approval of the Owner and at no additional cost to the Owner.
<br />The contractor and sub-contractor shall review the plans, details and previous work by others for satisfactory and
<br />appropriate completeness as adequate substrate for the installation of their scope of work. Report deficiencies
<br />immediately in writing to the developer/owner and architect. Failure to do so, or commencement of work without
<br />such notification will constitute an acceptance by the contractor of suitability of previous work by others.
<br />Do not scale these plans or details.
<br />All products will be installed in compliance with their manufacturers listed requirements, recommendations and in
<br />strict compliance with approved laboratory test reports (i.e. ICC-ES reports, N.E.R., F.A., U.S. reports, etc.)
<br />installation will meet all requirements necessary to maintain product guarantees and warranties. Failure to satisfy
<br />manufacturers installation requirements will constitute the contractor's/sub-contractor's acceptance of products
<br />guarantee or warranty liabilities.

<br />types of materials to which sealant is applied
<br />3.Cleaners: Where required in lieu of primers, use those recommended by sealant manufacturer.
<br />4.Joint filler: Must be compatible with sealant used and as recommended by sealant manufacturer.
<br />5.Open cell neoprene or plastic foam "rod".
<br />6.Felt tape: MIL-F-5656A, pressure-sensitive adhesive with interliner on one face, 1.5 mm thick.
