SEPARATELY ISSUED ATTACHMENTS

DIVISION 1 - GENERAL REQUIREMENTS

The County of Sacramento Standard Construction Specifications dated September 2001, revised March 2004, January 2008, January 1, 2016, and November 1, 2024, including applicable Standard Drawings and technical provisions, are hereby made part of these specifications. The following project-specific Special Provisions modify or supplement the Standard Construction Specifications (SCS). Where these Special Provisions conflict with the SCS, these Special Provisions govern for this Project only. SCS sections not modified below remain in full force and effect.

MODIFICATIONS TO STANDARD CONSTRUCTION SPECIFICATIONS

1-1 GENERAL

The following statement shall be added:

Pursuant to Public Contract Code Section 22034 and Sacramento County Code Section 2.61.058, the CUPCCAA informal Contract will be awarded by the Deputy County Executive for Community Services or other County official with proper delegated authority, subject to the current statutory limits and County procurement procedures.

2-1 BID PROPOSALS

The following paragraphs are added:

The Bid shall be submitted as a lump-sum Base Bid unless Attachment C identifies a separate bid item, allowance, additive item, or deductive item.

The Base Bid shall include all Contractor-performed labor, supervision, project management, artwork receiving and handling, assembly, rigging, qualified operators, art-handling tools, temporary works, supplemental equipment, protection, engineering required for the Contractor’s means and methods, coordination, submittals, field verification, cleanup, closeout, and incidentals necessary to complete the Work in accordance with the Contract Documents.

The following are not included in the Contractor’s Base Bid:

1. Fabrication and delivery of the artwork;

2. Installation of the permanent suspension cables and primary structural attachment infrastructure;

3. Design engineering for the permanent artwork and permanent structural support system;

4. Specialized lift or access equipment furnished by the County and identified in Attachment D; and

5. Other Work expressly identified in Section 4-1.03 as Work by the County or others.

The Contractor shall provide all qualified operators, riggers, signal persons, spotters, temporary supports, rigging equipment, art-handling equipment, supplemental equipment, load-distribution materials, floor and finish protection, safety controls, and incidental materials required for the Contractor’s installation operations, except for equipment or services expressly identified as County-furnished.

The Contractor may obtain materials, manufactured products, equipment-rental services, common-carrier delivery, manufacturer technical assistance, professional engineering, and independent testing or inspection services, provided that such entities do not perform field construction or artwork-installation labor prohibited by Sections 2-5 and 2-8. Such services do not relieve the Contractor of responsibility for complete performance of the Work.

Bidders shall submit written questions regarding any apparent conflict, omission, licensing concern, or incomplete County-furnished equipment or scope information before bid opening. Material clarifications or changes will be issued only by written Addendum.

2-2 PREPARATION AND SUBMISSION OF BIDS

The provisions of Section 2-2 of the Standard Construction Specifications are replaced with the following:

By submitting a Bid, the Bidder acknowledges that it has carefully reviewed the Contract Documents, Addenda, approved drawings, available approved structural calculations and loading information, County-issued plans and exhibits, photographs, permit documents, and other project information furnished or expressly identified by the County for bidding.

The Pedestrian Walkway and Hub remain under construction and are not available for a pre-bid physical inspection. Submission of a Bid does not constitute a representation that the Bidder entered, inspected, measured, or independently verified an area that the County did not make available before bid opening.

The Bidder shall prepare its Bid based on:

1. The Contract Documents and Addenda;

2. The County-furnished bidding and reference information;

3. The disclosed access, Site-availability, equipment, and scheduling assumptions; and

4. The requirements reasonably apparent from the complete bidding information furnished by the County.

Actual field conditions shall be verified by the Contractor after the County authorizes access to the applicable area and before the Contractor delivers or moves equipment into that area or begins rigging, lifting, connection, or artwork-installation activities, as provided in Section 4-1.03(B).

Bid prices shall include all labor, supervision, materials, services, equipment, temporary works, coordination, field verification, protection, engineering for Contractor means and methods, and incidentals required to complete the Contractor-performed Work, except for Work or costs expressly identified as County-furnished or performed by others.

The Notice Inviting Informal Bids shall describe the Project in general terms, identify how to obtain the Contract Documents, and state the date, time, place, and electronic method for submitting Bids. No pre-bid conference or pre-bid job walk will be held.

OpenGov shall be the County-designated eProcurement platform for posting the bid opportunity, receiving written questions, issuing Addenda, receiving Addenda acknowledgments, receiving Bids and required bid attachments, and posting award-related notices, unless the Notice Inviting Informal Bids expressly states otherwise.

Bids, written questions, Addenda acknowledgments, substitution requests, and required bid attachments shall be submitted only through OpenGov or by another method expressly authorized in the Notice Inviting Informal Bids or written Addendum.

2-3 EXAMINATION OF PLANS, SPECIFICATIONS, AND SITE WORK

The provisions of Section 2-3 of the Standard Construction Specifications are replaced with the following:

No pre-bid conference or pre-bid job walk will be held. The Pedestrian Walkway and Hub remain under construction and are not available for pre-bid physical inspection. Attendance at a pre-bid conference or job walk is not a condition of Bid responsiveness.

Bidders shall prepare their Bids based on the Contract Documents, County-furnished bidding information, and written Addenda. Questions concerning the Work, access restrictions, staging, equipment, installation requirements, or other bidding information shall be submitted through OpenGov by the deadline stated in the Notice Inviting Informal Bids or written Addendum.

The County will furnish the available bidding information through the Contract Documents or written Addenda. The furnished information may include:

1. Approved drawings and specifications;

2. Approved structural calculations and permanent-support-system information;

3. Structural, floor-loading, equipment-loading, and load-distribution information;

4. Supporting Documents identified in Section 4-2.01;

5. Attachment D — County-Furnished Equipment, Accessories, and Services;

6. Approved deferred-submittal documents and permit-case information;

7. Artwork assembly and installation information;

8. Project photographs and visual-reference information;

9. Available information regarding adjacent construction, commissioning, access restrictions, staging, equipment routes, work-zone limitations, and anticipated Site availability; and

10. Other County-issued information expressly identified for Bidder review.

Bidders shall prepare their Bids using the complete information package furnished by the County. Furnished information shall be identified as either a Contract Document or a reference document.

Contract Documents govern the scope, permanent design, Contract Price, Contract Time, and allocation of responsibility. Reference documents and photographs are furnished to assist Bidders in evaluating the disclosed conditions but do not independently modify the Contract Documents unless expressly incorporated by written Addendum.

Because the Pedestrian Walkway and Hub remain under construction, photographs and other project information may depict conditions existing when the information was prepared and may not depict the final condition of the facility when Site access is authorized. No specific final turnover date, Site condition, or unrestricted access date is guaranteed except as expressly stated in the Contract Documents.

Before bid opening, Bidders shall carefully review the complete County-furnished information package and submit timely written questions regarding any apparent:

1. Conflict, discrepancy, ambiguity, or omission;

2. Missing, incomplete, or unclear information;

3. Access, staging, delivery, laydown, or work-zone limitation;

4. Equipment route, equipment-clearance, or equipment-compatibility concern;

5. Floor-loading, equipment-loading, point-loading, or load-distribution concern;

6. County-furnished equipment limitation, omission, or inconsistency;

7. Artwork, support-cable, connection, attachment, or permanent-support-system concern;

8. Licensing, safety, security, airport operational, or constructability concern; or

9. Other condition that may materially affect the Bid, equipment selection, means and methods, cost, schedule, safety, or performance of the Work.

Written questions shall be submitted through OpenGov by the deadline stated in the Notice Inviting Informal Bids or written Addendum. Material interpretations, clarifications, additions, deletions, or changes to the bidding requirements will be issued only by written Addendum through OpenGov.

Oral statements, informal correspondence, preliminary documents, and planning estimates do not modify the bidding requirements. Interpretations or explanations not incorporated into a written Addendum shall not modify the Contract Documents.

Submission of a Bid does not constitute:

1. A representation that the Bidder physically inspected an unavailable area;

2. Independent validation or professional certification of the permanent artwork design, permanent suspension system, permanent structural attachments, or base-building structure;

3. Acceptance of permanent-design responsibility not expressly assigned to the Contractor; or

4. A waiver of the Contractor’s obligation to verify actual field conditions after the County authorizes access.

The Contractor shall verify actual field conditions after the County authorizes access to the applicable area and before delivering or moving equipment into that area or beginning rigging, lifting, connection, or artwork-installation activities, in accordance with Section 4-1.03(B) and the applicable requirements of Sections 7-1 and 7-15.

Site availability, NTP-1, NTP-2, advance notice, field mobilization, commencement of Contract Time, and post-award access shall be governed by Sections 3-7, 7-1, and 7-15.

2-5 CONTRACTORS/SUBCONTRACTORS TO BE LICENSED AND REGISTERED

The Bidder shall hold, at the time required by California law and throughout performance of the Work, an active and valid California C-61/D-34 — Prefabricated Equipment Contractor license. A Class B — General Building Contractor license, without the required C-61/D-34 classification, does not satisfy this requirement.

The C-61/D-34 classification held by the Bidder shall be legally sufficient for all Work assigned to the Contractor by the Contract Documents. Identification of the required classification in the Notice Inviting Informal Bids, OpenGov posting, Contract Documents, or Attachment A does not authorize the Contractor to perform work outside the scope permitted by California law.

The Contractor shall self-perform one hundred percent (100%) of all field construction and artwork-installation Work using its own employees. No construction subcontractor or lower-tier construction subcontractor shall perform any portion of the Work. The Bidder shall identify “None” on any subcontractor listing form included with the Bid.

For purposes of this Section, the following are not considered construction subcontracting, provided that the entity does not perform field construction or artwork-installation Work:

1. Material and equipment suppliers;

2. Artwork fabricators whose fabrication and delivery are provided by the County or others;

3. Common carriers and delivery companies;

4. Equipment-rental companies;

5. Manufacturer representatives providing technical information or training;

6. Licensed professional engineers providing calculations or professional services for the Contractor’s means and methods; and

7. Independent testing or inspection agencies.

The Contractor remains fully responsible for all services, products, equipment, and information furnished by such entities.

The Contractor shall not introduce a means, method, temporary system, or installation approach requiring structural steel erection, permanent welding, scaffolding construction, electrical work, glazing, permanent structural modification, or other separately licensed construction work that is outside the lawful scope of the Contractor’s license.

When the Contractor determines that proposed Work or its proposed means and methods may require another contractor classification, the Contractor shall stop the affected activity and submit the matter through the RFI process. The Contractor shall not subcontract the affected Work. The Contractor shall use an alternative lawful means and method or proceed only after written County authorization and confirmation that the Contractor itself holds every additional classification legally required to self-perform the affected Work.

The Contractor shall maintain current registration with the California Department of Industrial Relations at all times required by applicable law.

The self-performance requirement is a material requirement of the Contract. Unauthorized subcontracting may constitute grounds for rejection of the Bid, withholding of payment, removal of unauthorized personnel, or other remedies available under the Contract Documents and applicable law.

2-6 COMPETENCY OF BIDDERS

Each Bidder shall submit with its Bid the qualification information and supporting documentation required by Attachment A — Minimum Contractor Qualifications. The three-Working-Day post-bid timing in Section 2-6 of the Standard Construction Specifications does not apply to this Project-specific qualification submittal.

In determining whether a Bidder is responsible and competent to perform the Work, the County may evaluate:

1. The Bidder’s direct experience with comparable suspended public art, museum or exhibit installations, architectural-feature installations, and rigging-intensive specialty installations;

2. Experience working within airports, occupied public facilities, museums, transportation facilities, or similarly sensitive finished environments;

3. The qualifications and experience of the Bidder’s proposed key employees;

4. The Bidder’s direct workforce, organizational capacity, equipment resources, and ability to self-perform all field construction and artwork-installation Work;

5. Safety performance and ability to comply with Project-specific safety requirements;

6. Finished-facility protection experience;

7. Ability to coordinate with the County, Airport Operations, Airport Security, the Artist, and other affected parties; and

8. Ability to meet the required Project schedule.

The Bidder shall not rely on the experience, workforce, equipment, qualifications, or organizational capacity of a proposed construction subcontractor, affiliate, supplier, or other separate legal entity to satisfy a minimum qualification assigned to the Bidder.

Compliance with the contractor-license, Department of Industrial Relations registration, and self-performance requirements of Section 2-5 is mandatory.

Failure to submit material qualification documentation required with the Bid may result in the Bid being determined nonresponsive. Failure to demonstrate compliance with the minimum qualifications may result in the Bidder being determined nonresponsible.

2-8 SUBCONTRACTORS

The provisions of Section 2-8 of the Standard Construction Specifications are replaced with the following:

The Contractor shall self-perform one hundred percent (100%) of all field construction and artwork-installation Work using its own employees. Construction subcontractors and lower-tier construction subcontractors are not permitted.

For this Project, the Contractor’s own organization means workers employed and paid directly by the Contractor and under the Contractor’s direct supervision and control. Equipment may be owned or rented by the Contractor; however, personnel performing field construction or artwork-installation labor shall be employees of the Contractor.

The Bidder shall complete and submit the County’s designation-of-subcontractors form with its Bid and shall enter “None” for construction subcontractors. Listing a proposed construction subcontractor is inconsistent with this material self-performance requirement and may result in rejection of the Bid.

The following entities are not considered construction subcontractors for purposes of this requirement, provided they do not perform field construction or artwork-installation labor:

1. Material and equipment suppliers;

2. Common carriers and delivery companies;

3. Equipment-rental companies;

4. Manufacturer representatives providing technical information, training, or product support;

5. Licensed professional engineers providing calculations or professional services for temporary works or Contractor means and methods; and

6. Independent testing or inspection agencies.

The Contractor remains fully responsible for all products, equipment, services, calculations, information, and assistance furnished by such entities.

No entity other than the Contractor may perform Work requiring a California contractor license. The Contractor shall not introduce a means, method, temporary system, or installation approach requiring separately licensed construction Work outside the lawful scope of the Contractor’s license.

The Contractor shall not add a construction subcontractor after award. Nothing in this Section waives or modifies the Contractor’s obligations under the Subletting and Subcontracting Fair Practices Act or other applicable law.

3-1 TIME OF AWARD

Award timing shall comply with the SCS and CUPCCAA informal bidding requirements. If bid results exceed the informal bid threshold, the County shall not proceed to award unless directed by Contracts/Purchasing and County Counsel and authorized under applicable law.

3-3 AWARD OF CONTRACT

Award, if made, shall be to the lowest responsive and responsible bidder that satisfies the Contract Documents, CUPCCAA requirements, licensing, DIR registration, bonding, insurance, qualification, and bid submission requirements.

3-4 PERFORMANCE AND PAYMENT BONDS

Performance and payment bonds are required as stated in the SCS, County contract documents, and applicable California law. The specialty fine-art nature of the Work does not waive public works bonding requirements. Contractor shall provide required bonds before execution of the Agreement and before any field Work begins.

3-7 EXECUTION OF CONTRACT

The first paragraph of Section 3-7 of the Standard Construction Specifications is replaced with the following: After award by the County official or body authorized under applicable law and County delegated authority, the successful Bidder shall sign and return the Contract, together with complete, certified copies of the Performance Bond, Payment Bond, and required insurance evidence, within ten (10) Calendar Days after receipt of the documents. Receipt by the Agency of the signed documents constitutes execution of the Contract. After signature by the Agency, one copy of the executed Contract, bonds, and insurance evidence will be returned to the Contractor. The remaining provisions of Section 3-7 remain in effect.

The County may award the Contract and complete execution of the Agreement before the Project site is available for field mobilization or artwork installation. Site availability is not a condition precedent to Contract award or execution.

No Work shall begin until the Agreement has been fully executed, required bonds and insurance have been approved, and the County has issued the applicable written Notice to Proceed.

The County may authorize the Work through the following Notices to Proceed:

1. NTP-1 — Limited Notice to Proceed. NTP-1 may authorize only the administrative, coordination, planning, scheduling, Request for Information, and submittal activities expressly identified in NTP-1. Unless expressly authorized otherwise in writing by the County, NTP-1 does not authorize field mobilization, receipt or staging of artwork, delivery or movement of equipment at the Site, rigging, lifting, installation, or other physical on-Site Work.

2. NTP-2 – Full Notice to Proceed. NTP-2 authorizes field mobilization and commencement of the on-Site Work expressly identified in NTP-2, subject to the conditions, limitations, and field-verification requirements of Section 7-1. The date the County issues NTP-2 is the NTP-2 Effective Date and Day 1 of the Contract Time established in Section 7-15.

Execution of the Agreement or issuance of NTP-1 does not constitute a representation that the Site is ready for field Work and does not commence the Contract Time established in Section 7-15.

The Bidder acknowledgment and pricing assumptions applicable to deferred Site availability are established in Section 2-3. Detailed requirements governing NTP-1, NTP-2, Site access, advance notice, field verification, field mobilization, and commencement of Contract Time are established in Sections 7-1 and 7-15.

3-9 INSURANCE

The provisions of Section 3-9 of the Standard Construction Specifications are supplemented by the following Project-specific requirements.

The Contractor shall procure and maintain the insurance required by:

1. Section 3-9 of the Standard Construction Specifications;

2. The Agreement;

3. These Special Provisions; and

4. The final County Risk Management-approved insurance requirements included in the Contract Documents.

The County Risk Management-approved insurance requirements, including applicable coverage types, limits, endorsements, evidence-of-coverage requirements, and other Project-specific conditions, shall be included in the bid package before advertisement or issued by written Addendum before bid opening.

Changes to insurance requirements before bid opening shall be issued by written Addendum. After bid opening and before Contract execution, material changes to insurance requirements shall be addressed in accordance with applicable law and County procurement procedures. After Contract execution, changes to insurance requirements shall be administered through the applicable Contract-change provisions.

In addition to the liability coverage required by the Standard Construction Specifications and Agreement, the Contractor shall provide the property and equipment coverage expressly required by the County Risk Management-approved insurance requirements for the following, as applicable:

1. Contractor-furnished tools, rigging, art-handling equipment, temporary access systems, temporary supports, protection materials, and supplemental equipment;

2. Rented or leased equipment under the Contractor’s care, custody, control, or use;

3. County-furnished specialized lift or access equipment identified in Attachment D while under the Contractor’s care, custody, control, or use;

4. County-furnished artwork components and artwork-side hardware after documented transfer of custody to the Contractor; and

5. Other property for which the Contractor assumes custody or responsibility under the Contract Documents.

Required property coverage may include Contractor’s Equipment, Rented or Leased Equipment, Inland Marine, Installation Floater, Bailee or Fine Arts coverage, or equivalent coverage expressly approved by County Risk Management.

The Contractor shall provide Professional Liability insurance when the Contractor or a professional-services consultant provides stamped engineering, temporary-works engineering, lift or rigging engineering, equipment-loading analysis, floor-loading analysis, load-distribution engineering, or other professional services for the Contractor’s temporary works or means and methods.

Professional Liability coverage is not intended to transfer responsibility for the permanent artwork design, permanent suspension system, primary structural attachment infrastructure, permanent building structure, or other permanent-design services provided by the County or others.

Contractor’s Pollution Liability is not required for the Base Bid unless the coverage is expressly required by the County Risk Management-approved insurance requirements or hazardous or regulated-material Work is added to the Contractor’s scope through written Addendum or Contract Change Order.

The Contractor shall submit all required certificates, endorsements, schedules, and other evidence of insurance within the time required by the Agreement and before:

1. Beginning field Work;

2. Receiving custody of the artwork;

3. Taking custody or control of County-furnished equipment; or

4. Performing an activity for which the applicable coverage is required.

County furnishing of artwork, equipment, access information, loading information, design documents, or other property does not relieve the Contractor of its insurance obligations or its responsibility for property and equipment under its care, custody, control, or use.

County review or acceptance of insurance documents does not:

1. Represent that the Contractor’s insurance is sufficient to cover every risk;

2. Limit the Contractor’s liability or responsibility under the Contract Documents;

3. Modify the Contractor’s indemnification obligations;

4. Transfer responsibility for Contractor means and methods to the County; or

5. Waive a coverage requirement.

No owner-controlled, contractor-controlled, or other County-provided insurance program applies unless expressly identified in the Contract Documents.

In the event of a conflict among insurance provisions, the order of precedence established by the Agreement and Section 4-6 shall apply. The final County Risk Management-approved Project-specific insurance requirements expressly incorporated into the Contract Documents shall govern the Project-specific coverage, limit, endorsement, and evidence-of-coverage requirements.

3-9.01 INSURANCE REQUIREMENTS

The following project specific insurance requirements supplement 3-9 of the Standard Construction Specifications of the Agreement:

INSTALLATION FLOATER: CONTRACTOR shall procure, maintain, and keep in force at all times during the term of the Contract and until the date of transfer of the insurable interest to and acceptance by COUNTY, at the CONTRACTOR’s sole expense, or Installation insurance with limits of liability equal to one hundred percent (100%) of the contract value of the work. Valuation shall include the cost of materials and the cost of labor to install materials. Coverage shall be written on a completed value, non-reporting form, on a replacement cost basis, and shall cover the property against all risks of physical loss or damage. The property covered shall include the work, including any materials, equipment, or other items to be incorporated therein while the same are located at the construction site, stored off site, while in transit or at the place of manufacture. The policy shall contain a provision that the interests of the COUNTY, CONTRACTOR, and its subcontractor are covered and that any loss shall be payable to the COUNTY, the CONTRACTOR, and its subcontractors as their interests may appear.

4-1 INTENT OF CONTRACT DOCUMENTS

The following paragraphs are added to Section 4-1 of the Standard Construction Specifications and define the Project-specific scope, responsibility allocation, installation requirements, and limitations of the Work.

The Contractor is responsible to the County for complete performance of all Work assigned to the Contractor by the Contract Documents. All field construction and artwork-installation Work shall be self-performed by the Contractor’s own employees in accordance with Sections 2-5 and 2-8. Construction subcontractors and lower-tier construction subcontractors are not permitted.

The organization, format, headings, divisions, or sections of the Contract Documents do not divide the Contractor’s responsibility, authorize subcontracting, or relieve the Contractor of responsibility for completing the Work assigned to it.

Existing conditions depicted or described in the Contract Documents and County-furnished reference information are based on available record and field information. Because the Pedestrian Walkway and Hub remain under construction, actual conditions may change before the County authorizes Site access.

After the County authorizes access to the applicable area and before delivering or moving equipment into that area or beginning rigging, lifting, assembly, connection, or artwork installation, the Contractor shall verify the reasonably observable field dimensions, elevations, clearances, access constraints, support-cable locations, connection points, equipment routes, staging areas, work limits, and other conditions affecting the Contractor’s installation operations in accordance with Section 4-1.03(B).

The Contractor shall promptly notify the County in writing of any conflict, discrepancy, missing condition, nonconforming condition, access limitation, clearance issue, support-system issue, equipment incompatibility, licensing concern, or other condition that may affect the Work. The Contractor shall not proceed with the affected Work until written County direction is provided.

Contractor review, coordination, field verification, or use of County-furnished drawings, calculations, loading information, or other permanent-design documents does not constitute independent validation, certification, redesign, or acceptance of responsibility for the permanent artwork design, permanent suspension system, permanent structural attachments, or base-building structure.

4-1.01 CUTTING AND PATCHING

The following paragraphs are added:

The Contractor’s Base Bid does not include structural cutting, drilling, coring, welding, grinding, power-actuated fastening, permanent structural modification, or installation or alteration of the permanent suspension system or primary structural attachment infrastructure, except for Work expressly identified in the Contract Documents as Contractor-performed artwork-installation Work.

No cutting, drilling, coring, welding, grinding, power-actuated fastening, opening, removal, relocation, or alteration of the artwork, permanent suspension system, structural attachment infrastructure, glazing, curtain wall, ceiling system, wall system, structural framing, fire- or life-safety system, electrical system, mechanical system, communications system, security system, conveyance system, or architectural finish shall be performed without prior written County authorization.

Apparent conflicts, field discrepancies, proposed alterations, or conditions requiring cutting or modification shall be submitted in accordance with Section 4-7 before the affected Work proceeds. Written County authorization does not permit the Contractor to perform Work outside the lawful scope of the Contractor’s license.

The Contractor shall patch and restore surfaces disturbed by authorized Contractor Work to match adjacent construction and finishes unless otherwise directed in writing by the County. Cutting and patching shall not reduce structural capacity, impair fire- or life-safety systems, damage finished construction, void applicable warranties, or interfere with airport operations.

Damage or unauthorized alteration caused by the Contractor shall be repaired or replaced by the Contractor at no additional cost to the County using a method accepted in writing by the County.

4-1.02 WORK AND LIMITATIONS

The following paragraphs are added:

Existing airport facilities, completed construction, adjacent construction, commissioning activities, public circulation, and airport operations shall be maintained without interruption except as specifically authorized in writing by the County.

The Contractor shall coordinate its Work with the Department of Airports, Project Manager, Project Inspector, Airport Operations, Airport Security, Airports Maintenance Division, CMID/DGS, the Artist or Artist’s representative, the Architect or County-designated structural engineer when required, equipment suppliers, commissioning teams, adjacent contractors, and other County-authorized representatives.

The Contractor’s work limits, access routes, staging areas, delivery locations, laydown areas, work windows, equipment routes, and controlled-access zones shall be limited to those approved by the County. The Contractor shall not enter or use public circulation areas, operational areas, completed or finished areas, restricted areas, or adjacent construction areas without prior County authorization.

The Contractor shall perform the Work in a manner that protects the artwork, finished facility, existing systems, building components, adjacent construction, airport personnel, passengers, the public, and airport operations.

The Contractor shall not interrupt, disconnect, relocate, impair, or otherwise affect any building, utility, security, communications, conveyance, electrical, mechanical, or fire- or life-safety system without prior written County authorization.

4-1.03 PROJECT-SPECIFIC SCOPE OF WORK

The Sacramento International Airport Pedestrian Walkway Hub — Flight Paths Public Art Installation Project consists of furnishing all labor, supervision, project management, qualified art handlers, qualified rigging personnel, qualified or certified equipment operators, tools, rigging, Contractor-furnished installation hardware not expressly identified as County-furnished, temporary protection, load-distribution materials, engineering for the Contractor’s means and methods, safety controls, coordination, cleanup, closeout documentation, and incidentals required to install David Brooks’s public artwork entitled “Preserved Flight Paths” (also referenced in the procurement documents as “Flight Paths”).

The Contractor’s Work shall extend from documented transfer of custody of the County-furnished artwork components through complete assembly, installation, adjustment, inspection, punch-list correction, cleanup, closeout, and County acceptance, except for items expressly identified in the Contract Documents as Work by the County or others.

All field construction and artwork-installation Work included in this Section shall be self-performed by the Contractor’s own employees under the Contractor’s direct supervision and control. Construction subcontractors and lower-tier construction subcontractors are not permitted.

A. Artwork Installation Scope

The Contractor shall install the complete Flight Paths artwork system, including, but not limited to, the following:

· Ten (10) individual tubular-aluminum flight paths constituting the suspended Preserved Flight Paths artwork, as documented in Supporting Documents SD-06 and SD-12.

· Prefabricated artwork sections fabricated in approximately 30-inch lengths and shop-welded into sections of roughly 10 feet, to be joined on Site at overlapping sleeves to form the ten complete flight paths, as shown in SD-06.

· Twelve (12) cast-aluminum bird sculptures, including their supplied attachment components and final positioning at the locations shown in SD-05 and SD-12.

· Birds 5, 6, 7, 8, 9, and 12 mounted to curtain-wall horizontal aluminum mullions. The remaining six birds consist of three soffit-mounted birds, one column-mounted bird, one bird mounted on the wall by the elevator, and one bird mounted on the upper-level railing, in the locations shown in SD-05.

· Cable-supported assemblies, overlapping-sleeve joints, bird attachments, rigid attachments, bracing connections, and other artwork-side connection and restraint components assigned to the Contractor by this Section and the Supporting Documents, including:

a. At each overlapping-sleeve joint, install not fewer than three (3) supplied 1/4-inch bolts. Use every prefitted hole and supplied fastener; where four prefitted holes are provided, install four bolts. Do not add, omit, enlarge, or relocate holes or substitute hardware without written County direction and any required permanent-design and authority-having-jurisdiction approval.

b. At each artwork-side suspension connection, connect the cable to the artwork using the condition shown in SD-10 and SD-12: a Gripple device or a continuous-through-artwork cable condition, as applicable. Do not introduce another connection method without written County authorization and any required permanent-design and authority-having-jurisdiction approval.

c. Install the orange-coded Artist Scope (furnish-and-install) connection work shown in SD-10 as Contractor Work for this procurement, using the County-furnished artwork and prefitted or supplied hardware. Blue, gray, and pink scope remains CMAR/County Work unless expressly reassigned in writing.

d. Limit direct curtain-wall connections of suspended flight-path elements to the approved locations for Flight Path A, Sections 2 and 4. Flight Path B does not connect directly to the curtain wall and is restrained or attached to structural-steel supports as shown in the approved documents.

e. For curtain-wall birds 5, 6, 7, 8, 9, and 12, drill the two required 1/4-inch holes through the applicable horizontal aluminum mullion and install the 1/4-inch-20 threaded rods welded to the bird feet with stainless-steel binding barrels secured from the underside, in accordance with SD-05 and SD-07.

f. Install County-approved connection rods, threaded receiving connections, plates, fittings, aircraft cable, cable loops, wire-rope thimbles, Gripple devices, cable clamps, orange-scope restraints and bracing, fasteners, and incidental hardware required for a complete installation within the Contractor’s assigned scope.

· Assembly, lifting, hoisting, positioning, connection, alignment, and securing of the artwork components.

· Final tensioning, alignment, adjustment, stabilization, visual positioning, and verification of all suspended artwork components.

· Coordination of Artist review through the County for the visual alignment, orientation, composition, and final appearance of the artwork.

· Final inspection and verification that all Contractor-installed components are complete, secure, properly positioned, and consistent with the approved Contract Documents.

The Contractor shall perform all orange-coded Artist Scope shown in SD-10 and the corresponding artwork-side assembly and connection work expressly required by SD-05, SD-06, SD-07, and SD-12. The Riparian brass wall décor is a separate artwork from Preserved Flight Paths and is not part of this Contract, regardless of any orange designation shown in SD-10 or other scope-interface information.

The Contractor shall not add supplemental cables, braces, restraints, clamps, supports, tie-backs, attachment points, or other components that alter the approved free movement, loading, load path, geometry, or structural behavior of the artwork.

The Contractor shall not omit, relocate, substitute, loosen, tighten, shorten, lengthen, reroute, or modify an approved hanger, restraint, cable, connection, attachment point, support, or other component without prior written County authorization and, when required by the County, approval from the County-designated design professional or applicable authority having jurisdiction.

The Contractor shall not tension, loosen, adjust, relocate, or otherwise alter CMAR-installed blue-, gray-, or pink-coded suspension or structural-support scope, except for the drilling, through-bolting, artwork-side connections, rigid attachments, and bracing expressly assigned to the Contractor by this Section and the Supporting Documents.

Final component quantities, assembly groupings, labels, locations, and Contractor-installed hardware shall be governed by the final verified County-furnished artwork inventory and the Contract Documents.

The Contractor shall promptly report any discrepancy involving quantities, inventory, labels, drawings, hardware, connections, or field conditions before beginning the affected assembly or installation.

A material increase, decrease, or change in the verified inventory or Contractor-assigned scope shall be addressed under the Contract provisions governing changes. The Contractor shall not proceed with materially changed Work without written County direction.

B. Pre-Installation Coordination and Field Verification

After the County authorizes access to the applicable area and before delivering or moving equipment into that area or beginning rigging, lifting, assembly, attachment, connection, or artwork installation, the Contractor shall verify the reasonably observable field conditions affecting the Contractor’s operations.

Field verification shall include, as applicable:

1. Access routes and equipment-delivery paths;

2. Staging and laydown areas;

3. Work-zone limits and operating clearances;

4. Overhead, side, door, threshold, and turning-clearance restrictions;

5. Field dimensions, elevations, artwork connection locations, and attachment interfaces;

6. Accessibility, location, and apparent readiness of the preinstalled suspension system and permanent attachment infrastructure;

7. Floor conditions, available equipment-loading information, load-distribution requirements, and finish-protection conditions;

8. Compatibility of the proposed equipment, rigging, temporary access systems, and means and methods with actual conditions; and

9. Interfaces with adjacent construction, commissioning, airport operations, security requirements, and public or employee circulation.

The Contractor shall compare actual field conditions with:

1. The Contract Documents;

2. Supporting Documents SD-01 through SD-04, as applicable;

3. Available structural and equipment-loading information;

4. Attachment D;

5. Reviewed Contractor submittals; and

6. Other applicable County-furnished information.

The Contractor shall document field verification through measurements, photographs, marked-up plans, checklists, or other records appropriate to the affected activity.

The Contractor shall promptly notify the County in writing of any missing, damaged, inaccessible, misaligned, incorrectly located, substituted, obstructed, unsafe, or nonconforming condition.

The Contractor shall not deliver or move affected equipment or begin affected rigging, lifting, connection, or installation activities until identified discrepancies have been resolved or addressed by written County direction.

Field verification does not authorize the Contractor to relocate, alter, modify, repair, reinforce, or redesign any permanent artwork component, permanent support, structural attachment, building component, or Work performed by the County or others.

C. Receiving Artwork, Inspection, Inventory, Custody, Handling, Cleaning, Touch-Up, and Acceptance

The Contractor shall participate in a joint receiving inspection with the County when the artwork is delivered to the County-designated receiving location.

The Contractor shall prepare and maintain the Artwork Receiving and Inventory Log required by Attachment B. The log shall document:

1. Delivery and custody information;

2. Crates and artwork components received;

3. Artwork-side hardware received;

4. Visible condition;

5. Shortages or missing items;

6. Damaged packaging or components;

7. Photographs; and

8. Transfer of custody.

The Contractor shall document visible damage, shortages, missing components, damaged packaging, or other apparent nonconforming conditions on the applicable delivery or receiving documents before acknowledging receipt and shall promptly notify the County.

After documented transfer of custody, the Contractor shall protect the artwork from damage, contamination, theft, unauthorized handling, improper storage, equipment movement, construction activity, and incompatible materials.

Only qualified Contractor employees and County-authorized persons may handle the artwork. Suppliers, delivery personnel, manufacturer representatives, consultants, equipment providers, and other nonemployees shall not perform artwork-installation labor.

The Contractor shall use art-handling, rigging, padding, blocking, protection, and cleaning materials suitable for the artwork materials and finishes.

The Contractor shall not repair, repaint, refinish, alter, modify, or perform aesthetic touch-up of an artwork component without prior written County authorization.

Damage caused by Contractor receiving, custody, handling, staging, protection, rigging, lifting, installation, cleaning, equipment movement, or other Contractor operations shall be corrected at no additional cost to the County using a method approved in writing by the County.

County participation in receiving, inspection, review of the Artwork Receiving and Inventory Log, authorization to proceed, inspection, or acceptance does not relieve the Contractor of responsibility for custody, protection, proper handling, Contractor-performed Work, or Contractor-caused damage.

Nothing in this subsection limits or modifies the Contractor’s indemnification, insurance, warranty, or other obligations under the Contract Documents.

D. Equipment, Access, Rigging, and Floor Loading

The County will furnish the specialized lift or access equipment identified in Attachment D.

The Contractor shall provide qualified or certified equipment operators employed directly by the Contractor and all required Contractor-employed riggers, signal persons, and spotters, unless Attachment D expressly states that the County will provide an operator.

The Contractor shall furnish all rigging equipment, art-handling equipment, supplemental equipment, temporary access systems, temporary supports, load-distribution materials, floor and finish protection, barricades, safety controls, tools, and incidental equipment required for the Contractor’s means and methods.

The Contractor shall provide engineering required for its temporary works, rigging, lifting procedures, equipment loading, load distribution, temporary supports, temporary access systems, and other installation means…
