Project Phasing, Funding, and Operational Continuity

Only 70 miles from C&S to LEX

Multi-phase terminal renovations require careful planning to maintain operations, protect passengers, and coordinate across stakeholders.

Our approach focuses on operational continuity, minimal disruption, and close collaboration with airport staff. We will align phasing with funding strategies and airport priorities to ensure sequencing supports financial constraints while maximizing operational value.

Working with airport leadership and operations, we will review the anticipated phasing plan and identify opportunities to streamline construction.

Reducing unnecessary phase breaks lowers costs, limits temporary conditions, and reduces complexity—especially for building systems like MEP infrastructure that are difficult to replace across multiple phases. Fewer, more coordinated phases minimize rework, temporary installations, and ripple effects across construction areas.

Our Terminal Planning Lead will guide the phasing effort to ensure operational needs drive sequencing decisions. Using passenger flow modeling and capacity analysis, we will test interim conditions to confirm ticketing, screening, holdrooms, and baggage claims maintain acceptable service levels throughout construction. This planning-first approach ensures temporary conditions are both feasible and operationally sound.

The C&S Team will evaluate swing spaces, sequence utilities, coordinate with operations, and plan around peak travel periods. We will also define responsibilities for pre-bid meetings, bid evaluations, award recommendations, and establish clear Construction Administration procedures for submittals, change management, logistics, and phased close-out.

Project Elevate—Concourse A Expansion Gerald R. Ford International Airport Authority | Grand Rapids, Michigan

Similar in scale and size to LEX | Small Hub!

C&S was part of a multi-discipline design team responsible for the civil and structural components for Project Elevate. Participation included construction safety and phasing, site demolition, utility relocation, pavements, pavement markings, foundation design and structural steel design.

Concourse A Expansion is the first phase of Project Elevate and includes a $97 million extension of Concourse A to accommodate projected passenger growth over the next 20 years.

Building construction added eight gates and new amenities. Concourse A had seven gates, while Concourse B had eight gates.

The first portion of Project Elevate added eight new gates to Concourse A, widening the 66-foot concourse to up to 120 feet and lengthening by 510 feet to a total of more than 900 feet. Expansion of the terminal apron to support this state-of-the-art concourse was completed as an enabling project prior to building construction, thanks to more than $14.4 million in federal and state commitments from the Federal Aviation Administration and the Michigan Department of Transportation.

Project Elevate represents continued implementation of

Main Terminal Improvements

Long Island MacArthur Airport | Ronkonkoma, New York

Many items at the main terminal building at Long Island MacArthur Airport were in need of general maintenance upgrades and aesthetic improvements to extend useful life, increase efficiency, and improve the overall passenger experience.

Due to funding cycles and overall budget, the project was split into multiple bid packages and alternates were developed to ensure full use of available funding.

The first bid package involved a complete roof replacement of the terminal building roof system, totaling approximately 93,000 square feet. The existing roof was partially removed down to existing insulation, which was replaced where water damaged, and includes additional insulation to exceed energy code and a PVC roof membrane system for a 30-year warranty.

The terminal renovations portion involved multiple scope items to

Similar in scale and size to LEX | Small Hub!

collectively improve function and efficiency. A major item was the replacement of the four in-bound baggage carousels. To increase security, the new units were designed to feed once through the SIDA into the terminal in lieu of the existing configuration that cycled baggage back to the security side if not picked up. Additionally, control upgrades, ability to incorporate RFID scanning technology, and an oversized baggage slide were included.

The existing tug canopy was rehabilitated with new LED lighting and screens at the baggage carousels to reduce the impact of weather during the winter months.

The project also upgraded the landside vestibules to reduce the amount of thermal transfer when doors are in use. To do so, the vestibule footprint was enlarged to create greater distance between interior and exterior sliding doors and air curtains reduce the thermal transmittance. A major design element was to reduce the amount of vestibules from a total of six, three on each wing, down to four to reduce the large penetrations through the building envelope. All vestibules contain sliding glass door units and a decorative wood ceiling to match the existing ceiling treatments in the terminal. Lastly, a set of double doors was replaced incorporating ADA compliant operators.

Albany International Airport | Albany, New York Contact: John LaClair Albany County Airport Authority (518) 242-2222 jlaclair@albanyairport.com

Similar in scale and size to LEX | Small Hub!

C&S led a multi-phase project to modernize the terminal building and enhance the passenger experience at Albany International Airport.

The project was fast-tracked over four months to meet an aggressive construction completion schedule.

A significant project highlight is the renovation of the “Times Square” area in the central terminal, which houses the main concessions spaces and is the central hub of the postsecurity passenger circulation. Upon exiting security, the new terrazzo flooring pattern is expressed and radiates from this central point; main spines of the pattern highlight the major paths, while arched highlights express motion toward each of the three concourse wings. Additionally, the seating areas are updated with a new mix of furniture with power connectivity. A new wood ceiling element similarly expresses movement toward the concourses.

An existing concession space was renovated to provide an interior pet relief room, complete with artificial turf, sanitary measures, a fake log, and seating. www.cscos.com

The wayfinding and signage is being replaced throughout the terminal with a clean aesthetic that maintains the existing color palette, but highlights the new “international style” of terminal signage. Exterior signage improvements also include new illuminated curbside signage and large illuminated letters that announce the terminal from the entrance road.

Renovation of all five main restrooms includes finishes and infrastructure enhancements and corrected operational issues and concerns and completed the modernization effort.

A new roof assembly and photovoltaic array replaced an existing leaking and non-functioning skylight and supplements existing terminal power usage.

Other improvements include operations and maintenance enhancements that corrected ongoing issues within the facility, such as HVAC improvements and replacement of escalators.

Terminal Modernization, Expansion & Airside Program

Charles M. Schulz-Sonoma County Airport | Santa Rosa, California Contact: Jon Stout County Airport Manager (707) 565-7243 jstout@sonomacountyairport.org

Sonoma County retained C&S under a five-year on-call Construction Management contract to support a portfolio of airside and landside capital improvement projects funded through local, state, and federal sources. In this role, C&S served as the County’s strategic advisor for procurement, design oversight, funding compliance, and delivery implementation, including guiding the Airport through its first Alternative Project Delivery (APD) utilizing Construction Manager at Risk (CMAR).

As a primary commercial service, non-hub airport experiencing sustained passenger growth and increased airline service, the Airport required a delivery model capable of maintaining uninterrupted operations while executing complex phased improvements.

Airline ticketing, TSA checkpoints, hold rooms, baggage systems, rental car counters, and backof-house tenant areas remained fully operational throughout construction.

CMAR was selected to

allow early contractor engagement, structured risk allocation, and collaborative phasing essential to preserving operational continuity.

CMAR Procurement & Preconstruction Framework

C&S advised the County through development of an FAA-compliant CMAR procurement process, including:

♦ Drafting RFQ/RFP evaluation criteria aligned with FAA APD requirements ♦ Establishing preconstruction services scopes and fee structures ♦ Developing risk allocation matrices and contract general conditions ♦ Structuring phased Guaranteed Maximum Price (GMP) amendment strategies

During preconstruction, C&S led integration meetings between the Architect/Engineer (A/E) and CMAR contractor to ensure constructability reviews, cost modeling validation, and schedule alignment at defined design milestones (30%, 60%, 90%).

Independent cost estimates were reconciled with CMAR open-book pricing to maintain transparency and alignment with program funding constraints.

GMP Development & Cost Control Strategy

Given the multi-year, multi-phase nature of the program, C&S implemented a structured GMP development approach that included: ♦ Progressive cost model refinement during design advancement

♦ Early trade partner engagement for high-risk scopes (structural tie-ins, baggage systems, MEP upgrades, apron interfaces) ♦ Detailed quantity takeoff validation and reconciliation workshops ♦ Transparent subcontractor bidding with County participation in scope leveling GMP packages were strategically phased to align with operational sequencing, allowing the County to maintain budget flexibility while mitigating escalation risk. C&S facilitated scope validation sessions to clearly define allowances, unit price contingencies, escalation assumptions, and owner-directed changes prior to GMP execution.

Risk Register & Contingency Management

A formal project risk register was established early in preconstruction and maintained throughout design and construction. Risks were categorized by operational impact, cost exposure, and schedule sensitivity. Key risk drivers included:

♦ Maintaining secure sterile corridors and TSA compliance during phased construction ♦ Baggage system cutovers within active terminal operations ♦ Utility tie-ins to existing infrastructure without service interruption ♦ Airline tenant relocation sequencing and temporary facility requirements www.cscos.com

♦ Sustainability initiatives, including photovoltaic integration, introduced middesign

C&S structured contingency management in accordance with CMAR best practices:

♦ Contractor contingency allocated for scope development and trade coordination risk ♦ Owner contingency reserved for unforeseen conditions and programmatic changes ♦ Separate tracking logs for contingency drawdown with documented justification and County approval ♦ Monthly risk review meetings to reassess exposure and adjust forecasts This disciplined approach provided full cost transparency and allowed the County to manage financial risk proactively rather than reactively.

Program Scope & Phased Implementation

The overall program included landside enabling projects such as new surface parking facilities, controlled access systems, ADA path-of-travel upgrades, rideshare improvements, and service road bridge work over environmentally sensitive areas.

Terminal phases included expansion of passenger holding areas, TSA flow enhancements, baggage system modernization, concession improvements, and apron interface coordination.

Because enplanements and total passengers continued to grow postpandemic, terminal capacity and processing areas required expansion while remaining operational. The CMAR model enabled detailed pullplanning workshops, collaborative sequencing, and real-time design adjustments without compromising airline operations.

Value Delivered Through CMAR The CMAR delivery model created measurable program advantages:

♦ Early identification and mitigation of operational risk within an active terminal ♦ Reduced change order exposure through design-phase constructability integration ♦ Transparent GMP development with cost validation at each milestone ♦ Controlled contingency management with documented risk tracking ♦ Ability to fast-track enabling packages while design progressed on terminal core elements Through structured procurement guidance, disciplined GMP negotiation, and rigorous contingency management, C&S supported Sonoma County in delivering a complex, phased modernization program while maintaining uninterrupted commercial air service and preserving County control over design intent.

Passenger Terminal Improvements Ithaca Tompkins International Airport | Ithaca, New York Contact: Roxan Noble Airport Director (607) 257-0456 rnoble@tompkins-co.org

C&S was the architect, engineer, and construction manager for the $20 million 15,600-square-foot terminal expansion and renovation at Ithaca Tompkins International Airport. The first phase included a 7,100-square foot expansion to house enhanced baggage screening and baggage make-up space, relocation of and upgrades to offices, building utility systems upgrades, exterior entrance canopy improvements, retrofit and relocation of one existing and installation of three new passenger boarding bridges.

Phase 2 added 8,500 square feet to accommodate an enhanced passenger screening and holding area, additional conference space and a baggage conveyance system, restroom renovations, LED lighting, new geothermal well field and HVAC system, and new solar canopy covered system for terminal area parking.

The terminal building is primarily heated and cooled using seven large air handling units (AHUs). Each AHU has a condensing unit that rejects heat to a condenser water loop attached to a cooling tower

at the north end of the building.

The AHUs also have hot water coils, which are heated by hot water from a boiler loop.

The county had three options for replacing this system. The first was a straight, one-for-one replacement with new, more efficient equipment.

The second was to replace the

system with a traditional heat pump system using a new cooling tower and condensing boiler plant to heat and cool a condenser water loop.

The third was to use geothermal heat pumps using a geothermal well field as their heat sync and source.

To evaluate the energy savings associated with these options, C&S

created an eQuest model of the existing building and calibrated it using utility data from 2017. Using this calibrated model, three new models were created with the different HVAC systems. In addition, engineers’ estimates of probable costs and estimated paybacks were generated for the three design options. This modeling effort was accomplished using a 50% cost-share through the NYSERDA FlexTech program. www.cscos.com

It was determined that the geothermal heat pump system was the best option to incorporate into phase 2 of the project. Construction was spread over multiple phases to minimize disruption. Airport employees and patrons had to use the space during construction, so safety was primary.

acre), ground-source heat pumps, and water-to-water heat pumps located throughout the building.

The well field is comprised of (58) 500’ deep vertical wells. These wells are piped in a parallel piping distribution from the well-field to a main system manifold located in the airport terminal. That manifold is then piped up to a second-floor mechanical room to where the building-pumps are located for the building condenser loop. The pumps then distribute the 40°F – 90°F condenser water throughout the building to ground-source heat pumps and water-to-water source heat pumps. The building’s airside system is a decentralized system.

Central dedicated outdoor air systems (which are ground-source heat pumps) deliver conditioned, space neutral ventilation air to the zone. The zone ground source heat pumps were designed to allow flexibility of thermal control over the different spaces throughout the building. Lastly, for the Baggage Make-up Area, a ventilation system with hot-glycol coil served the room throughout the year for IAQ purposes. This unit’s heating coil was served by (2) water-to-water source heat pumps that could provide 120°F water for tempering outdoor air during the winter months.

The geothermal heat pump system at Ithaca Airport Terminal Building is made up of a vertical well-field (0.65 158.072.001-Hybrid

Architectural/Engineering Plan Review Services

Cincinnati/Northern Kentucky International Airport | Hebron, Kentucky

C&S performed third party plan reviews and assessments as well as construction phasing reviews for proposed development projects at the Cincinnati/Northern Kentucky International Airport, including a tenant owned hangar building and Amazon developments.

A steamlined review process along with review checklists were tailored and applied to each project. Tools such as Bluebeam sessions were utilized to allow multiple reviewers access to the same files and provide efficient output of comments into client provided tracking logs. Projects were reviewed at each stage of the design (30%, 60%, 90%, 100%, IFC, and addenda) as assigned and requested by the client. C&S developed a tracking log to monitor the status of each submittal and track the back checking of comments as they were addressed. Comments identified as higher risk to the client were brought to their attention and meetings were conducted to discuss those issues.

www.cscos.com

The C&S review team included experts in areas such as constructability, FAA standards, construction phasing, airfield pavements, stormwater, utilities, planning & airspace, landside access/roadways, and buildings facilities.

The Amazon Development Project was broken into multiple bid packages. C&S provided a quick review period and comment turnaround time as the nature of the project was fast paced ($1.5 billion development constructed over two years). C&S reviewed and provided comments on bid packages at each stage of design including utility relocations, mass

Runway 9-27, Taxiway K and Taxiway J Rehabilitation

Cincinnati/Northern Kentucky International Airport | Hebron, Kentucky

The Kenton County Airport Board (KCAB) hired C&S to design the rehabilitation of Runway 9-27 and parallel Taxiways K and J at Cincinnati/N. Kentucky International Airport (CVG). With cargo service growing rapidly and the expansion of Amazon's Prime Air Operations at the Airport, it was critical to improve the airport's longest, and primary nighttime, runway and adjacent taxiways.

The project design includes the rehabilitation of the 7,100-foot asphalt over concrete portion of Runway 9-27.

Reviewing FAA standards, the existing runway was not fully in compliance. These items have been addressed in the design of the rehabilitation and include increasing the shoulder width of Runway 9-27, blast pads width and length, Runway Safety Area (RSA) grades, and several taxiway turns for 747-8 aircraft movements.

The FAA put a strong emphasis on reductions to runway incursions at airports. As a Runway Incursion Mitigation (RIM) safety improvement, Taxiway J2 will be realigned to eliminate direct straight-line access from the terminal apron to Runway 9-27.

www.cscos.com

In several locations along Runway 9-27, existing infields did not meet RSA compliance. Following old standards, catch basins were located within the RSA. The project design includes addressing these locations to meet current FAA design standards. The grades will be improved and numerous storm drain and electrical structures will be modified or replaced to meet current aircraft load criteria.

Runway edge and centerline lighting, taxiway lighting, airfield guidance, and distance remaining signs within the project limits will be rehabilitated or replaced.

There was a significant reduction in energy and maintenance costs to the airport with the updated LED electrical system.

Five potential phasing alternatives were developed and refined to incorporate prospective funding

scenarios. Key considerations used to develop each phasing scenario include minimizing the closure times of Runway 9-27 and Runway 18C-36C, accommodating multiple Aircraft Design Group taxiway operations, particularly 747-8, and coordinating taxiway closures to accommodate runway operations. The development of the final phasing design incorporated feedback of key airlines and tenant stakeholders, and a Safety Risk Assessment. Construction started in September of 2020 with Runway 9-27 closures and was completed in 2022 with a single six month shutdown of Runway 9-27.

Snow Removal Equipment Building Expansion

Gerald R. Ford International Airport | Grand Rapids, Michigan The new facility required extensive site work, including demolition of the previously mentioned existing ground service equipment fuel and runway de‑icing facility as well as drainage and grading modifications.

GFIAA contracted with C&S to rapidly design a replacement facility, enabling construction of the SRE building to proceed without delaying airport operations.

The Gerald R. Ford International Airport Authority (GFIAA) had an extensive fleet of Snow Removal Equipment (SRE) vehicles and associated specialty equipment that could no longer fit within the existing airport field maintenance facility. C&S undertook a comprehensive programming effort to quantify the additional space required to properly house and maneuver the full fleet. The design team evaluated every feasible approach, including standalone structures and expansion of the existing airport field maintenance facility.

The project required careful navigation of limited sites, complex adjacencies, and the need to maintain continuous airport operations throughout www.cscos.com

construction, and demanded a highly strategic phasing plan that minimized disruptions to the airport, maintain circulation, and daily client operations. The ability to maintain operational continuity was a central driver in selecting the preferred solution and structuring the construction schedule.

The existing field maintenance facility site was boxed in by several critical elements: a large sand storage building to the southeast, the ground service equipment fuel and runway de‑icing chemical facility to the northeast, and the SIDA boundary to the south. After evaluating all options, the preferred solution was a 61,615‑square‑foot building addition that maximized storage capacity while ensuring safe and efficient SRE vehicle movement.

The project was delivered through a Design‑Bid‑Build process, consistent with GFIAA’s standard procurement approach and received Airport Improvement Program (AIP) funding, which added important requirements for documentation, competitive bidding, and cost control. Budget stewardship was critical throughout design; maintaining alignment with funding constraints and competitive construction pricing was a key success factor.

Terminal Apron Reconstruction

Gerald R. Ford International Airport | Grand Rapids, Michigan

C&S designed and performed construction administration and observation for the reconstruction of the deteriorated 150,000-square-yard air carrier apron pavement and infrastructure at Gerald R. Ford International Airport. Components included new PCC pavement and asphalt shoulders, utility improvements, including water main and sanitary sewer, new drainage system and infrastructure for collection and disposal of deicing glycol, and terminal area lighting.

The pavement geometry adjacent to the concourses was evaluated to allocate space for parked aircraft and aircraft movement around the ends of each concourse and alternatives were prepared. C&S used 3D modeling to develop several concepts to improve overall drainage and glycol collection. The apron pavement includes separated drainage and glycol collection systems with the glycol runoff collected in multiple underground tanks outside the apron pavement. The new system significantly reduces the laborintensive operations and cost of glycol collection. C&S also integrated sustainability into the design and construction, conducting a charrette to collaboratively determine options for enhancing economic considerations, airfield operations, natural systems, and society. Through this www.cscos.com

process several unique and unconventional approaches emerged.

Construction phasing was a significant challenge because the airport could not afford to close several gates concurrently. C&S prepared multiple alternatives to minimize impact to aircraft and gate operations.

Additional alternatives addressed funding scenarios, given the uncertainty of FAA participation levels.

With numerous constraints and the project’s scale, the final phasing plan included seven phases over two years. The project received 5 bids and the lowest was 5% below C&S’s construction cost estimate.

tion meetings prior to each phase change. This gave all stakeholders the opportunity to ask questions and voice any concerns during the ever-changing construction project.

This proactive approach improved communication and reduced the construction time. The project received multiple awards from industry organizations including Michigan Concrete Organization, ACEC and ASCE.

Terminal Apron Expansion

Gerald R. Ford International Airport | Grand Rapids, Michigan

The Gerald R. Ford International Airport apron expansion was an opportunity to increase the airport infrastructure capacity to meet its rapidly growing demand. Travel demands are projected to grow considerably over the foreseeable future, prompting the need to increase overall capacity, including expanding the apron and existing terminal building.

C&S was the prime firm on this $15M apron expansion project leading the engineering design, bidding, and construction observation and administration. C&S assisted the airport authority with securing supplemental discretionary funding from the FAA including preparation of the justification and application.

Time and quality were key requirements to complete the apron expansion project successfully.

The airport authority asked C&S to complete the design under an accelerated schedule to seamlessly compliment the on-going terminal apron reconstruction and the upcoming terminal building expansion. The 2-year apron reconstruction was still under construction as C&S designed the apron expansion, along with design of the Concourse A expansion. All three projects had an overlapping footprint. It was imperative to deliver a cost-conscious, flexible, quality design to accommodate simultaneous construction of all www.cscos.com

three projects. C&S found ways to save cost by constructing temporary pavements and utility improvements that minimized rework during the construction of each project.

Continuously changing existing and design conditions was a significant challenge that the design teams had to overcome as the result of the colocated, concurrent projects.

Another challenge for the team was the increasing aircraft operations and passengers. Ford Airport was one of the fastest growing airports in the country during this time adding flights and new airlines.

Phasing of the concurrent projects required careful planning of gate closures, remain-overnight parking, and taxi routes. C&S led stakeholder engagement meetings during the design to gather input and stakeholder coordination meetings dur-

ing construction to keep all parties up to date on the ever changing conditions and schedules.

The apron expansion was completed on-time to accommodate the Concourse A expansion allowing the terminal apron to be fully utilized with maximum flexibility for aircraft operations.
