  Stone Mountain, GA                                                     Feb.28, 2024



Assumptions & Clarifications

The following clarifications and assumptions, organized by CSI division, are included as part of the Agreement.

General Notes
   1. This GMP Estimate for Champion Theme Middle School is based upon the following documents, unless
       otherwise stated in Clarifications below:
              a. Project Manual Issued for Construction dated Jan.20,2022 by SSOE
              b. Plans Issued for Construction dated Jan.20,2022 by SSOE
              c.   Addendum #1 – Not provided
              d. Addendum #2 dated June.21, 2022 by SSOE
              e. RFI log#1 (see attached)


This estimate includes:
    1. Construction Manager will furnish and maintain General Liability Insurance through a GL/Excess BBC’s
        master insurance program. The General Liability Insurance will be billed at a fixed rate of 1.10% of the GMP
        with the first Payment Application. Direct bills from the master program are not available as the fixed rate is
        based on the entire portfolio of US projects and calculated as a fixed rate.
    2. Balfour Beatty P&P Bond will be provided at a fixed rate of 0.561% of the GMP. Bond costs will be billed
       100% with the first Payment Application.
    3. Builder’s Risk policy will be provided by Contractor and be billed at actual cost with the first Payment
       Application at a value equal to the cost of work. Owner shall maintain property insurance for facility.
    4. Construction Manager will furnish and maintain Subcontractor Default Insurance (SDI) through BBC’s master
       insurance program. SDI will be billed at a fixed rate of 1.52% of the cost of work. Direct bills from the master
       program are not available as the fixed rate is based on the entire portfolio of US projects and calculated as a
       fixed rate. Construction Manager will purchase, maintain, and enroll all eligible and prequalified
       subcontractors, suppliers, and vendors into a SDI program at a fixed amount which shall be billed in total at
       the outset of the project. Any subcontractors who do not meet SDI prequalification requirements who have
       subcontractors over $250,000 will be bonded at the contractor’s discretion.


Division 1                       General Requirements
This estimate includes:
    1. Digital Documents: All documents including closeouts will be transmitted digitally. No provisions for hard
       copies are included.
    2. Potential Trade Escalation: Should the award of certain Trade Contracts not allow for a fixed-price structure
       where the Trade Contractor would bear all or part of the responsibility for future inflation and/or cost
       escalation for the entire scope and value of the Trade Contract due to either (1) market conditions (supply
       chain, etc.) that won’t allow for firm fixed price commitments at time of Trade Contract award and/or (2) at the
       request of the Owner who wants to remove such Escalation Allowances or Escalation Contingencies for
       anticipated or potential future inflation and/or cost escalation from the initial Trade Contract amount and fully
       bear that future risk, the Expenditure Authorization Letter will capture such details and outline the mutually
       agreed-upon timeline and process for which the material escalation items will be measured and later

  CLARIFICATIONS AND ASSUMPTIONS
  Champion Theme Middle School                                            GMP Estimate
  Stone Mountain, GA                                                      Feb.28, 2024



        reconciled. Upon reconciliation of any material escalation item from Trade Contracts, the GMP contract
        amount will be adjusted accordingly via Change Order. Should the Owner elect to deviate from the agreed-
        upon timeline for reconciling the escalation as outlined in the Expenditure Authorization Letter, any further
        cost or schedule impacts resulting from that change will cause the GMP to be adjusted via the Change Order
        process outlined in the Agreement.
    3. General Conditions: Are established as a lump sum that shall be paid in equal installments on a monthly basis
       over the course of the project.
    4. Construction Contingency: Our GMP Proposal contains 7 percent (7.00%) of Cost of the Work construction
       contingency (based on the 100% CD’s). The Construction Contingency will be used at the reasonable
       discretion of the Contractor to address unexpected circumstances and expenses incurred to: (a) pay for
       purchase of subcontracts, suppliers and vendors in excess of budgeted line item(s) within the GMP; (b) fill
       scope gaps between trade subcontractors; (c) repair un-assignable damaged work; and (d) settle minor
       disputes with trade subcontracts at the completion of the Project. In essence, these are expenses which are
       ordinary and customary that does not constitute a change in the Work as defined in the Agreement. The
       Construction Contingency can be used to offset cost overruns incurred by the Contractor for General
       Conditions or General Requirements. Conversely, any savings will flow into the Construction Contingency.
    5. Pandemic/ Supply Chain Issues: Any delays in deliveries, unavailability of materials or equipment, labor
       shortages and/or cost escalation attributable to epidemic, pandemic or public health emergencies as well as
       supply chain issues will constitute compensable delays or change events.
    6. An assumption that to the extent the specifications do not involve design elements performed by different trades
       and is otherwise a customary proprietary design or engineered component requiring a professional engineer’s
       stamp on shop drawings such as fire suppression systems, fire alarm systems and other similar activities,
       Construction Manager’s liability for design errors and omissions is limited to amounts we recover from the
       subcontractor or its insurance carriers.
    7. Installation, rental, and removal of three (3) eight-classroom modular classroom trailers to relocate students
       during construction. Rental included for 26 months (from 5/1/2023 through 07/01/2026). Classroom trailers
       include electrical, mechanical, plumbing, and fire protection installation. This scope includes an allowance for
       electrical and plumbing (water/sewer) final connections since the final tie-in locations are not known at this time.
       See Allowances.
This estimate excludes:
    8. Repairs to existing structure(s) other than as provided on the Contract Documents.
    9. Security guards, security cameras, or security services.
    10. Any code updating of existing facility not specifically shown or identified on the documents.
    11. Utility consumption fees, except temporary construction power due to this being occupied campus.
    12. Design responsibility inherent in performance specifications that involve assemblies or interfaces among
        design elements performed by different trades or are otherwise not customary proprietary specifications
        obtained from single manufacturers.
    13. Specifications that state the following or something substantively similar to the following 1) “delegated design:
        design assembly or interface, including comprehensive engineering analysis by a qualified professional
        engineer, using performance requirements and design criteria indicated”; 2) requirements for code
        compliance and design features “whether or not indicated on the drawings,” and 3) references to design “by
        others” on the drawings.
    14. All Testing
