h. Revised Proposal Form – Part 2 for Fire Protection (Attachment 13B). Added breakout for Demolition.

i. Revised Proposal Form – Part 1 for Low Voltage (Attachment 14B). Modified Insurance breakout requirements and added option for extended warranty.

j. Revised Proposal Form – Part 2 for Low Voltage (Attachment 14B). Added breakout for Demolition.

3. Clarifications

a. The Preliminary Schedule of Subcontractors submitted by the proposers do not have to list specific subcontractors or suppliers used for obtaining the MWBE goal. It may simply outline general areas of the scope of work of this subcontractor where the proposer will attempt to achieve the MWBE goals. This does not commit the proposer to be obligated to any subcontractor or supplier as of the submission of the proposal on January 18, 2011. However, upon receipt of a Subcontract for construction of the work, Subcontractor will be required to submit the FINAL Schedule of Subcontractors after they have bid the work and will then be committed to the subcontractors, suppliers and percentages listed.

eW Cove Powercore2800 KDimmable, efficient light for interior alcoves and niches

eW® Cove Powercore is a dimmable, linear LED fixture that provides an energy-efficient, low-maintenance alternative to traditional cove lighting in applications requiring white or solid-color light. With its low profile, rotating housing, flexible end-to-end locking power connectors, and range of colors and color temperatures, eW Cove Powercore is the perfect choice for a wide range of interior retail, exhibit, hospitality, and architectural settings. Patented Powercore, which powers eW Cove Powercore fixtures directly from line voltage, supports long runs of fixtures on a single circuit while offering improved operational efficiency and cost-effective installation and operation.

• Integrates patented Powercore technology — Powercore rapidly, efficiently, and accurately controls power output to eW Cove Powercore fixtures directly from line voltage. Contractor-friendly installation dramatically simplifies installation and helps lower total system cost

• Range of colors and color temperatures — Available in five color temperatures, ranging from a warm 2800 K to a cool 5000 K, and three solid colors (Amber, Green, and Blue). Warmer color temperatures are appropriate for intimate, open environments such as restaurants and hotel lobbies, while cooler color temperatures are appropriate for lighting clean and efficient spaces such as offices, classrooms, and hospitals.

• Smooth dimming capability — Patented DIMand technology offers smooth dimming capability with standard ELV-type dimmers.

• Support for 100, 120, and 230 VAC — eW Cove Powercore accepts a power input of 100, 120, or 230 VAC for consistent installation and operation from line voltage in a variety of locations.

• Easy installation — Powercore delivers line voltage directly to the fixtures, simplifying

installation by eliminating the need for external power supplies and allowing long product runs. Easy-to-install 4 ft (1.2 m) mounting tracks allow quick project setup in linear applications.

• Compact and flexible — eW Cove Powercore low-profile fixtures fit in narrow alcoves, display cases, light boxes, and other tight spaces where light sources requiring ballasts, external power supplies, and other auxiliary equipment can not.

• Flexible mounting and positioning — With end-to-end locking power connectors that can make 180º turns, eW Cove Powercore fixtures are easy to position in even the most challenging mounting circumstances. Fixtures rotate in 10° increments through a full 180° for precise aiming and color mixing. Optional mounting tracks support vertical and overhead positioning. 1 ft (305 mm) and 5 ft (1.5 m) jumper cables can add extra space between fixtures.

Addendum #04 (January 6, 2011)

1. Mechanical/Plumbing , Electrical, Fire Protection, & Low Voltage Services Engagement

BARC is soliciting competitive sealed proposals (“CSP” or “Proposal”) from qualified subcontractors for Preconstruction Services and Construction required in connection with the existing site assessments, design, construction, and commissioning of the proposed DFW Airport Terminal Renewal and Improvement Program (TRIP) with respect to the following four distinct trades:

• Mechanical/Plumbing

• Electrical

• Fire Protection

• Low Voltage

The Proposal shall be for the work associated with DFW Airport Terminal A only, which is currently planned to be divided into three or more phases (the “Project”).

The intent of this solicitation is to select one subcontractor to execute all portions of the Mechanical/Plumbing work, one subcontractor to execute all portions of the Electrical work, one subcontractor to execute all portions of the Fire Protection work and one subcontractor to execute all portions of Low Voltage work. The four successful subcontractors will be expected to function as part of the BARC’s preconstruction team during the development of documents for Terminal A, including providing a variety of design assist advice, constructability reviews and construction cost analysis services necessary to support design and construction in an effort to optimize the schedule and cost of the project.

A complete proposal with all required cost breakdowns and other related documents must be submitted no later than the date and time described in Section 10 of this CSP. BARC will first review the Proposal and make a determination of the proposals within competitive range as outlined in selection criteria in section 15.

2. About the Construction Manager (BARC)

The BARC joint venture will be responsible for the renovation of Terminals A and C under the DFW Airport Terminal Renewal and Improvement Program through 2017. BARC is composed of four contractors including: Balfour Beatty Construction, Azteca Enterprises, H.J. Russell & Company, and CARCON. BARC is committed to supporting the success of the DFW Airport Terminal Renewal and Improvement Program, and to maximizing the positive impact that the program brings to the Dallas and Fort Worth and North Texas communities.

3. About the Owner (DFW Airport)

Located halfway between the cities of Dallas and Fort Worth, Texas, DFW International Airport is the world's third busiest, offering nearly 1,750 flights per day and serving 57 million passengers a year. DFW has been named "Best Airport for Customer Service in North America" by an Airports Council International survey of passengers in 2006 and 2007. DFW International Airport provides non-stop service to 134 domestic and 37 international destinations.

4. About the Architect/Engineer (Jacobs Design Team)

DFW International Airport Development and Engineering selected Jacobs Engineering Group Inc. (Jacobs), a global leader in integrated multidisciplinary architectural and engineering design as one of two prime design consultants to provide Design and Design Management Services for the DFW Airport Terminal Renewal and Improvement Program. Jacobs and its team of design sub-consultants, the Jacobs Design Team (JDT) will prepare the construction documents for Terminal A and C as the Architect and Engineer of Record. The selected subcontractors will be required to work closely with BARC and the TRIP design professionals to ensure the constructability of the construction documents, adherence to budget constraints, and that the constructed work meets specified performance requirements.

5. General Scope and Nature of the Work

Current plans require construction to begin in Terminal A in early 2011. Terminal A is scheduled to complete by the fall of 2014 followed by Terminal C, which should complete by the end of 2017. The current construction phasing plan requires approximately one-third of a terminal to be under construction at a given time without disrupting existing day to day airport operations elsewhere. Terminal A is approximately 1.1 million square feet that is 35 years old and primarily is functioning on the originally installed building systems. The project scope is to provide for a complete renovation of the existing facility including the replacement of the building system providing for an additional 30+ years of useful life, including replacement of all Terminal A systems, including plumbing, HVAC, fire protection, security, electrical, building management system (BMS), and voice & data. The project will be logistically complex in that only one-third of the terminal can be under construction at one time while the other two-thirds remain operational. Both new and existing systems will be utilized to provide conditioned air and utilities during construction. The construction zones defined by full height temporary partitions will have to maintain negative pressure to the operating terminal. Cross contamination of new systems from construction and from contaminates in

Addendum #04 (January 6, 2011)

the existing systems must be avoided to the extent possible. Charged and energized systems will be present throughout the construction phase. Therefore, extensive lock-out/tag-out procedures will be utilized to prevent injury or property damage at all valves and electrical equipment/panels. Lay-down space is in the Terminal construction zone limited to 5,000 SF for each selected subcontractor and all of its sub-tiers. Gated lay-down yards will be available on Airport property. With respect to demolition and replacement of the above-ceiling systems above and around the Baggage Handling System (“BHS”) on the ground floor, the BHS must remain operational without interruption from 5 am to midnight. BARC will provide one man/material hoist on the land side and one man/material hoist on air side on the opposite end of the building. No tower crane will be provided. All cranes and other lifting equipment will be provided by the Subcontractor. The maximum boom height of all cranes is 60 ft. Above-ceiling work should be done from scissor lifts limited to 3,000 lbs and smaller. The largest access to the construction area for installing large equipment and prefabricated items will be 28’-0” by 14’-0”. Subcontractor will be responsible for all disassembly and re-assembly of all equipment and pre-fabricated items to accommodate this size limitation. Subcontractors are expected to utilize BIM modeling for clash detection and to provide advice on optimum routing/zoning based on structural laser scan information or other structural backgrounds provided by BARC.

6. State of the Design Documents

The design documents are approximately 35% complete for the entire Project. The design documents related to Phase 1 being slightly more advanced than those for Phase 2 and 3. The design documents for the scope of temporary work necessary to take Phase 1 out of service and maintain Terminal operations are approximately 90% complete. Proposers are expected to provide a complete proposal to perform all work reasonably inferable from the design documents and necessary for a complete and functioning airport terminal in accordance with all applicable codes and industry practices. Therefore, the proposal process must be carefully managed and documented by both the Proposers and BARC to insure a consistent and accurate understanding of the entire scope of the project and that the proposals, when received, can be evaluated to accurately determine the best value for DFW Airport according to the scoring criteria below. To that end, communications between BARC and the Proposers that may affect the proposal responses must be written and must be provided to all Proposers. Proposers are encouraged to provide written questions throughout the proposal preparation process until the cutoff date of December 27, 2010 and should anticipate that the scope of the project will be defined sufficiently through the questions and answers and discussions process such that the final proposal submission will reflect the scope of work with sufficient precision to define when a change in scope may occur during the development of construction documents and preconstruction process. Proposers should assume that the documents and Exhibits provided in this CSP are intended to be complementary. What is required in one of the CSP documents is required by all, and the greater scope is intended to be provided, unless BARC directs otherwise in writing. In the event of a irreconcilable conflict between the CSP documents, the following order of precedence for the

DFW Airport Terminal Renewal and Improvement Program

Mechanical/Plumbing, Electrical, Fire Protection & Low Voltage Services

Instructions to Proposers Attachment 1

Page 5 of 25

Addendum #04 (January 6, 2011)

Proposal documents shall apply: 1) the Prime Contract; 2) these Instruction to Proposers; 3) BARC’s answers to Proposers’ questions; 4) BARC’s Scope of Work and Special Provisions; 5) Jacobs Engineering Design Narrative; 6) Subcontractor Proposal Clarifications and Assumptions; 6) Drawings; and 7) Specifications Proposers should carefully define the anticipated scope of Work in their proposals with the intent of providing the design team a roadmap to complete the design documents without a change in scope. All material assumptions that have the potential to be ambiguous as being inferred or necessary for a functioning airport terminal that are not shown or described on the CSP documents should be appropriately defined in the Proposal. To that end, Proposers should submit their detailed estimates, clarifications and assumptions, and any drawings/sketches to clarify their scope in a separate bound volume that does not count against the page limits for the proposal. All estimating information and other information unique and proprietary to a Proposer and marked as such in the proposal will be kept confidential to the extent allowed under applicable law.

7. Competition requirements and determination of allowable costs

In addition to the GMP amount for preconstruction services for entire project, the Proposal will contain i) a Guaranteed Maximum Price (GMP) for the construction cost of work of Phase 1, ii) an Initial Maximum Price (IMP) for the construction cost of work for Phases 2 and 3, and iii) a GMP for General Conditions for the entire Project. The intent is to convert the GMP/IMP amounts to a lump sum subcontract at or near the conclusion of the preconstruction period when the subcontractor has proven to BARC’s and DFW Airport’s reasonable satisfaction that it has achieved competitive bids on all purchased materials and equipment and subcontracted work. However BARC reserves the right to utilize a GMP contracting method for the entire duration of the subcontract. For all other cost items that will not achieve competitive bids, such as labor, supplies, small tools, shop-related costs, and any overhead rates or labor burdens, the subcontractor must provide certified cost and pricing data that provides all relevant information BARC and DFW may want to know to evaluate the reasonableness of the costs within the proposed lump sum price and conformance with applicable provisions of BARC’s contract with DFW Airport (the “Prime Contract”). To the extent subcontracted work includes exclusive local and M/WBE subcontractors as part of the subcontractor’s team, the exclusive sub-tiers must demonstrate competition or provide certified cost and pricing data to substantiate its costs as the subcontractor.

At the time the GMP/IMP is converted to a lump sum for each phase, all labor burden, overhead rates, shop rates, and equipment rates will be fixed in the subcontract based on the cost and pricing data previously provided and used for calculation of change orders to the lump sum contract. Until the selected subcontractor has met its obligations to convert to a lump sum amount for each phase, it shall be reimbursed for its costs allowable under BARC’s contract with DFW Airport with its proposed overhead/ fee percentage as indicated in estimate detail (containing all of the non-reimbursable elements defined in Prime Contract) applied to the actual cost of the work. To the extent the proposers have shop charges related to operation of prefabrication facilities associated with pre-fabricated components, those rates will be audited and fixed after award as a direct cost of the work and applied to all pre-fabricated material and labor cost. Shop charges do not include overhead and other off site costs (estimating, BIM, etc.) in connection with professional preconstruction services.

8. Anticipated bonding requirements

Because of the size and somewhat undefined scope and schedule of the project, BARC will requires at time of submission of CSP a Bid Bond in the amount 5% of the combined total for GMP for Preconstruction Services, GMP for General Conditions, and GMP for Phase 1. In addition, the successful subcontractors will provide a security bond in the amounts listed below to provide security that the Subcontractor will enter into separate subcontracts for Phases 2 and 3 in amounts not to exceed the IMP’s provided in the Proposal. Security bond requirements for each scope of work are as follows: Mechanical / Plumbing $5,000,000 Fire Protection $450,000 Electrical $3,500,000 Low Voltage $1,500,000 An initial Payment & Performance Bond will be required upon execution of the subcontract for Phase 1, which will include GMP for Preconstruction Services, the GMP amount for General Conditions for the entire project, and the GMP for Phase 1 construction labor, materials, and equipment.

Proposers should anticipate the following bond capacity will be required over the duration of the Terminal A project and that bonding up to two phases will be required. It is anticipated that Phase 1 bond will be closed out before Phase 3 is issued. Estimated maximum bonding amount will be as follows;

• Bond capacity for Mechanical/Plumbing: $75 million.

• Bond capacity for Electrical: $75 million.

• Bond capacity for Fire Protection: $6 million.

• Bond capacity for Low Voltage: $10 million.

9. Insurance program

DFW Airport will provide an OCIP that will cover all Worker’s Compensation, General Liability, Completed Operations, and Pollution Liability for all on-site operations. Therefore, proposers are required to provide their own off site CGL, offsite WC coverage, and AOA/Auto Liability for both on and off site operations as evidenced in attached exhibit G A more detailed OCIP manual will be provided in future addendum. All proposers are required to state the cost of insurance that has been omitted from their proposals in the designated line on the Proposal forms; however, DFW Airport reserves the right to conduct an audit to determine the actual avoided cost of insurance after completion of the work. Furthermore as a requirement of the safety OCIP, all employees working on the TRIP projects will be required to attend a two day safety and project orientation session. The training will be conducted in a classroom setting off airport property on Esters road. In addition to the two day orientation and safety training sessions, all persons in a supervisory role will be required to attend a one day management training session.

14. Scope of Work

1. General

a. To allow for the scheduled completion of the project in the fall of 2014, it is anticipated that the Project will be delivered via a design assist process with opportunity to recommend packaging of design and construction documents to expedite bidding and construction.

b. The selected subcontractors will be integral members to the TRIP Project Delivery Team. The primary focus of the selected subcontractors shall be to provide a variety of document reviews, budgeting, scheduling, phasing, and constructability reviews necessary to support the design and construction effort.

c. The selected subcontractors will be performing continuous budget management until the design is complete with responsibility to identify (at least monthly) scope creep and other events with cost implications to the subcontractor, including any usage of the established contingency within the GMP.

d. BARC intends to utilize the same selected mechanical/plumbing, electrical, fire protection and low voltage subcontractors for preconstruction and construction for Terminal A. BARC further intends to convert the cost reimbursable GMP contract to a firm, lump sum contract for each phase once the design is 70% completed and DFW has confirmed that competition has been achieved for all subcontracts or purchase orders issued by the subcontractors.

2. Preconstruction Services (15 Months)

a. Design / Preconstruction Services review meetings will be held as needed, but as a minimum, every week through the completion of the design phase and periodically thereafter, as required. The selected subcontractor shall attend and participate in all meetings. Meetings may be held at the Owner’s, Architect’s, Engineer’s, or BARC’s offices, whichever is deemed most appropriate at the time by the TRIP Project Delivery Team.

b. The selected subcontractors shall provide continual value engineering services addressing constructability; life cycle analysis; existing conditions surveys; availability of materials for

Mechanical/Plumbing, Electrical, Fire Protection & Low Voltage Services

Instructions to Proposers Attachment 1

Page 12 of 25

Addendum #04 (January 6, 2011)

specialized systems; comparative cost/benefit analysis for various systems. Budget/schedule impact will be evaluated with the Project Delivery Team as specific phases of the overall design are developed in order to avoid the development of the Contract Documents that exceed budget and schedule limitations.

c. In addition to the continuous budget management described in 1.b above, the selected subcontractors shall be required to follow the following process to reconcile estimates and/or changes in scope:

i. Prepare two fully detailed estimates in each area of each phase for their respective scopes of work utilizing unit costs as shown in detailed estimate (refer attachment 11C, 12C, 13C, and 14C) during CSP bidding time, which will be held and utilized in establishing GMP and Lump Sum pricing. These unit costs include all tools, consumables, markups, contingency, escalation, and fee. General Conditions and Preconstruction cost is not part of these unit costs.

ii. To track the changes against the accepted proposal price, schedule, and assumptions in the subcontract, The detailed estimates are due not later than two weeks after issuance 70% Construction Documents, and 100% Construction Documents for each Phase of TRIP. All supplemental estimates shall be submitted with a complete price breakdown (tracking line item changes in scope, refer attachment 11C, 12C, 13C, and 14C), detailed listing of qualifications and assumptions, inconsistencies, delays or problem areas which could impact budget parameters and final delivery into the construction phase of the project. Each subsequent estimate/budget shall address (and eliminate, if possible) the earlier assumptions and clarifications included in the previous budget.

iii. Subcontractor will demonstrate that it has achieved competition (i.e., expectation of at least three bids) for all items over $25,000 before any GMP is converted into a lump sum.

d. After GMP amounts are converted to lump sum, all new changes will be reconciled in accordance with the prime contract with cost and pricing data and as per Change Order Form (attachment 11E for Mechanical/Plumbing, attachment 12E for Electrical, attachment 13E for Fire Protection, and attachment 14E for Low Voltage) submitted with the proposal. BARC will utilize rates submitted in the proposal for all changes to the subcontract.

e. The selected subcontractors shall conduct constructability reviews for all phases in collaboration with the TRIP Project Delivery Team to determine that the design documents will result in construction documents that are sufficiently complete, accurate and coordinated to the existing conditions so as to reduce the risk of disruption, delay, change orders, and potential claims. At a minimum, the selected subcontractors will be responsible to verify the observable existing conditions as the design evolves and confirm the accuracy of the dimensions of design documents and prepare accurate as-built information for both existing and new features at least weekly and communicate any discrepancies to BARC. The mechanical and electrical constructability analysis will also include developing a comprehensive strategy to maintain conditioned air throughout the Terminal and maintaining indoor air quality using permanent or temporary systems during construction.

As part of the constructability reviews, the subcontractors shall develop and implement a comprehensive lock-out/tag-out process for systems within their scope to avoid injury to

Addendum #04 (January 6, 2011)

persons or property. No change orders will be issued related to errors or omissions or lack of coordination in the Construction Documents that were reasonably discoverable by a sophisticated subcontractor performing the work in similar circumstances.

f. The selected subcontractor shall continually seek to create value by identifying options to improve constructability and functionality, reduce capital or life cycle costs, or provide operational flexibility consistent with the Owner’s program needs.

g. The selected subcontractor shall assist the TRIP Project Delivery Team with schedule development by verifying schedule sequencing, logistics to expedite materials, verifying activity durations, and systems testing to meet the intent of the design.

h. The selected subcontractor shall assist the TRIP Project Delivery Team with creating performance standards to measure and track quality. This shall include, but not be limited to, developing quality procedures, quality assurance checklists, manufacturing mockups, conducting pre-work meetings, performing first work inspections, system checks and startup.

i. The selected subcontractor shall assist with reviewing Owner Furnished Equipment and furnishings, installation costs, and any other items that may potentially affect the construction costs.

j. The TRIP Project Delivery Team and selected subcontractors shall have as their goal, to minimize the need for requests for information (RFI’s) during the construction phase, through effective collaboration and communication during the preconstruction phase of the project. This will require the subcontractor’s full understanding of design requirements, including the design intent and all project technical requirements prior to commencement of construction.

c. Describe significant provisions in the joint venture agreement and each organization’s responsibility for sharing expenses, profit, loss, control of business operations, etc., on this project.

2. Criterion 2. D/MWBE/local participation. Weight (20) points. (All pages will count in the page count. Note: Page count for GFE (Good Faith Effort) will not count towards page count)

a. Phase I - Demonstrate through a written narrative, your efforts to involve and utilize

DMWBEs at the recommended goal level. This project has an aspirational DMWBE

goal of thirty five (35%) of the total dollar value of the contract including any change

orders. Describe where and how DMWBE resources will be involved in the project by

completing the Schedule of Subcontractors (Preliminary) form (Refer Attachment 17 and

Exhibit L for forms and DFW D/M/WBE Policy) for each team member identified. In

the event you are not demonstrating participation consistent with the aspirational goal,

documentation evidencing a good faith effort to meet the goal must be presented with the

proposal. (Good Faith Effort documentation is not counted against page limit.)

Phase II & III - Demonstrate through a written narrative your efforts to involve and

utilize DMWBEs at the recommended goal level. This project has an aspirational

DMWBE goal of thirty five (35%) of the total dollar value of the contract including any

change orders. Describe where and how DMWBE resources will be involved in the

project and included in your competitive bidding process.

b. Where a certified D/W/MBE partner represents less than fifty percent (50%) of the

partnership or joint venture, D/M/WBE participation at the prime level by the certified

D/W/MBE partner will count towards the 35% D/M/WBE goal. If the D/M/WBE

participation at the prime level comprises less than 35% of the total contract value,

including all change orders, the balance of the required 35% D/M/WBE participation

level must be obtained through certified D/W/MBE subcontractors. For example, if a

qualified certified D/W/MBE partner at the prime level provides 35% of the total contract

value, including all change orders, the entire amount of that participation shall be applied

to the goal and the goal shall be considered met. If a qualified certified D/W/MBE partner

provides 20% of the total prime contract value, including all change orders, the entire

amount of that participation shall be applied to the goal and an additional 15% shall be

obtained from certified D/W/MBE subcontractors in order for the goal to be considered

met.]

c. Provide a narrative demonstrating how you have achieved similar DMWBE participation

goals in the past using similar subcontracting plans. Include examples with proposed
