A. Division 1 - General Requirements /General Scope Clarifications

6/19/2013

1. The GMP is based on the 95% construction documents dated 04/15/2013, Addendum 01

dated 04/26/2013, and Addendum 02 dated 05/08/2013. A full list of contract documents

that the GMP is based on is included in Section Y.

2. Drawings P501 has the incorrect date (5/3/13), but I put it as 5/8/13 in the attachment.

E005, E111, E244, E311, E312, E313, E314, E321, E322, E331, E332, and E816 were issued in

Addendum 02, but do not have the revision label or date on them, but I put them as 5/8/13

in the attachment.

3. The GMP includes RFI's 1 through 91.

4. The GMP does not include any costs for pending Final Site plan approval, Final Building

Permit approval or BAR comments that may require design or scope changes not currently

shown in the contract documents, except for the following:

a. Includes an allowance for additional site light ing

b. Includes the cost of an additional exterior door at the gym

5. Hours of construction will be consistent w ith the City noise regulations in lieu of Article

3.2.1.

6. Professional progress photo documentation is included per the scope identified below.

a. Detailed Site-Survey Exact-Built"' (Pre-Construction) Detailed Pre-Slab Exact-Built"' of the Slab on Grade ONLY. This will capture all critical infrastructure and systems inside the slab prior to the placement of concrete or as directed by client

b. Detailed Exterior Skin Exact-Built that will capture the following items: i. Sub-grade waterproofing up to 5' below grade prior to backfill

ii. All wrapping of exterior of the building iii. Window installation- to include flashing of the windows iv. Waterproofing of the structure that will support initial panels v. Interior anchor points vi. Final installation conditions vii. Roof- Includes overlapping photo of every square inch at waterproofing stage

c. Detailed Interior MEP Exact-Built"' of the entire building to include documentation of all mechanical, electrical and plumbing systems, to be conducted after rough-ins are complete, just prior to insulation and or drywall, or as directed by client. Includes all walls and ceilings.

d. Executive Summary Slideshows Provided during progression at the same intervals and for the same durations as set forth above. Scope includes customizable sections for third party (i.e., Aerial Photographer) or Owner and Superintendent photograph collections. These will be dated and labeled per instruction of the respective party.

7. A schedule of allowances and holds is included in the Allowances and Holds tab of the GMP.

Below is a definition for each:

a. Allowances:

The term Allowance is defined as work shown on plans that is not possible or difficult to

completely define based on the information provided, therefore a quantity is provided

to cover the cost of this work. During construction if the cost to provide the work listed

in the Allowance is LESS than shown, the Construction Manager owes the balance to the

Owner; if the cost to provide the work listed in the Allowance is MORE than shown an

increase to the GMP will be required per the contract.

b. Holds:

The term hold is defined as work that can be identified and that a reasonable value can

be determined through experience and the contract documents, however the full cost

for this item may not be needed and thus it is better to carry this cost outside of a

subcontractors lump sum contract. During construction the if the cost to provide the

work listed in the Hold is LESS than shown, the balance goes to construction

contingency; if the cost to provide the work listed in the Hold is MORE than shown the

balance will come from the Construction Contingency per the contract documents.

8. The GMP includes technical assumptions and clarifications along with exhibits which form

the basis of our price. These assumptions and clarifications, along with the enclosed GMP

detail, represent our understanding of the scope of the project that is specifically identified

in the contract documents or which is reasonably inferred as being required to complete the

work. To the extent these Assumptions and Clarifications are inconsistent with the Contract

Documents; these Assumptions and Clarifications shall take precedence over the Contract

3

Jefferson-Houston Elementary School GMP Proposal

Assumptions and Clarifications

Documents, provided, however, that that nothing limits or diminishes any of the Owner's

rights, or that in any way expands any of the Owner's duties and obligations.

9. The GMP is based on open, non/proprietary specifications naming three or more

manufacturers whose products are acceptable under the base bid for each product, section

or work category. Reasonable substitutions may be made to specified materials, with no

charges to The Construction Manager or our subcontractors for reviewing the same.

10. For work defined as delegated design in the specifications and for the AV/IT package which

was previously awarded as design build, and potentially the Mechanical and Plumbing

package which may require design assist, the Owner and Architect shall provide all design

and performance criteria and coordination necessary to complete the specified work.

11. The GMP includes The Construction Manager's Subguard default insurance plan for all

subcontracted work in lieu of Subcontractor Payment and Performance Bonds at a rate of

. 78% of the Total Construction Estimate plus the CM Fee. See section Z below for Subguard

and CCIP details.

12. The GMP includes a Contractor Controlled Insurance Program (CCIP) which provides General

Liability and Workman's Compensation insurance coverage for The Construction Manager

and all subcontractors while on the project site. The CCIP price is a non-auditable fixed fee

based a rate of 2.098% of the sum total of the Direct Costs, General Conditions, Subguard,

Const ruction Contingency, and Builders Risk.

13. This GMP is based upon an the May 10, 2013 NTP from Alexandria City Public Schools with

milestone and completion dates as depicted in our attached GMP Project Schedule. We

assume that the Owner's partial use or occupancy of the buildings will not interfere with our

operations to complete the balance of the work.

14. We have assumed that the building permit will be granted by Alexandria City by June 27,

2013.

15. The schedule included outlines the major activities and demonstrates our plan to construct

this project. This schedule will be adjusted throughout the project as work progresses.

16. The GMP is based on the attached summary project schedule dated May 171h, 2013

including the services of their designers and consultants.

19. All costs for unforeseen below grade conditions not identified in the contract documents is

excluded.

20. Testing and inspection is by the owner.

21. All accepted Value Engineering items must be incorporated into Construction Documents

contract documents.

22. Standard warranties for all products and labor are included unless specifically stated

otherwise.

23. The GMP includes the fixed $1,270,158 General Conditions cost per the preconstruct ion

contract which was based on a volume of $35,500,000 plus $51,742 of additional GC's, a

4.1% mark-up on the total project cost above $35,500,000. The final amount of additional

GC's shall be reconciled with the final executed GMP amount at the rate of 4.1%.a mark up

24. For all future cl'laRges the iRcl1:1de Gross Receipts Ta)( aRd spell out s~:~bcoRtractor marl< ups

ups do not include any costs associated with schedule impact. Additional costs may be

incurred for any changes that impact the schedule. The Construction Manager will notify

ACPS of all changes that may have schedule impact per the Construction Management

above.

;M.;.25. All future Construction Manager deduct cost change orders shall include Subguard at
