C&S is one of the most diverse and capable aviation consulting firms in the U.S.

With more than 100 experts, C&S has one of the largest aviation groups in the country. Airports are our main business and we have spent 50 years refining our approach to delivering excellent aviation consulting. We are one of the most experienced and trusted firms in the country. From airfield pavements to terminal buildings to landside infrastructure to master and sustainability planning, C&S has the capacity and the experience to manage any assignment. With seasoned professionals in airfield and landside engineering, planning, architecture, sustainability, grants, construction services, land use and market strategies, and other specialized disciplines, we help clients realize the vision they have for their airports.

Airfield Engineering and Design

C&S designs all aspects of airfield infrastructure, including airfield pavements, access roadways, drainage, lighting, signage, fencing, structures, navaids, and more. We design rehabilitations and new construction of runways, taxiways, and aircraft parking aprons using both bituminous and Portland cement concrete. We have the capability to manage all sizes of pavement projects—from reconstruction of entire runways at hub facilities to small aprons at general aviation airports and everything in between.

C&S develops realistic, implementable master plans that address an airport’s value and relationship to the surrounding community and balance impacts on people and the environment. We take a holistic approach to planning that considers more than just mandated requirements, including integrating important factors like sustainability, business planning, and funding opportunities. We pioneered the field of sustainable master plans and are known nationwide for sustainability planning. We also prepare airport layout plan updates and narrative reports, which can be economical and time-efficient alternatives to a full master plan. As part of the ALP update process, we develop forecasts that are realistic and forward thinking to ensure development is justified and cost-effective. We also consider environmental conditions, preventing time-consuming surprises during the NEPA process.

Terminal Planning

Contact: Scott Tumolo | stumolo@cscos.com

We create a comprehensive strategy that involves developing “big ideas” for long-term development that can also be implemented incrementally in both a sustainable and financially feasible way. We advise airport clients from start to finish for terminal development, conduct site selection studies, prepare high-level requirements and alternatives during the master plan process, formulate demand capacity analysis and develop program requirements during program definition, and act as strategic advisors during design and construction. C&S is a leader in developing and using the latest technology for analysis. We can create in-house demand/capacity analysis specific to any airport, or we can use current industry standard applications, depending on the needs. We use aircraft simulation tools to understand aircraft movement on the airfield and apron areas. We have 3D visualization tools to help clients and stakeholders understand complex facilities and issues.

Construction Phase

Achieving a quality-built project is the responsibility of C&S’s construction managers. In recognition of the unique nature of the aviation industry, we have a full-time staff of construction managers, inspectors, and support staff who only work on aviation-related projects. Our construction team is OSHA certified and has training and certification in P-401. We use the latest in intelligent construction techniques, including employing equipment like the GPS rover for grade control and measurements. Our construction team’s involvement occurs throughout the design process, focusing on three areas—constructability, cost, and schedule. This gives design personnel and the sponsor the realities of a contractor’s perspective; feedback on construction phasing, methods, materials, and specifications; and contract packaging. Before construction, the team develops a detailed construction management plan that defines quality assurance for the project and quality control for our team. Once construction starts, our team focuses on the project’s “triple constraint”—quality, cost, and schedule. We encourage a partnering environment and work closely with contractors throughout the life of the project. C&S is an extension of your staff for the duration of the project, and your eyes and ears on the construction site. We use e-Construction for both document and photo management, and our inspection reports and records are stored in the cloud so that they are accessible anywhere.

Runway Incursion Mitigation

The FAA Runway Incursion Mitigation (RIM) program was initiated in 2015 to improve safety by reducing runway incursions. C&S completed one of the first RIM projects in the country, incorporating the new guidelines into an ongoing taxiway improvement project at Youngstown-Warren Regional Airport (ACEC Ohio Engineering Excellence Award winner). Strategies to improve runway safety include simplifying pavement geometry, correcting non-standard slopes, standard runway safety areas,  improving signage, and adding runway guard lights. We work with airports to help identify potential hotspots and design solutions to correct these threats to aircraft safety.

Centralized Receiving and Distribution Centers

Contact: Cory Hazlewood | chazlewood@cscos.com

A centralized receiving and distribution center (CRDC) can be a solution for  streamlining the processing of goods coming into an airport. C&S designs state-of-the-art CRDC buildings that enable airports to consolidate many scattered operations and staff into one location for increased efficiency and reduced costs. It also allows for implementation of one, clearly defined screening process—helping eliminate gaps in security. CRDCs are effective for all sizes of hub airport and creative financing options can make these facilities a reality even if they are not on the CIP. For example, public-private partnerships allow an airport to maximize CIP funds for critical airport infrastructure. Partnering with a private developer, an airport can set up a number of leaseback or installment payment options to benefit both partners over the course of many years.

Grants Administration

Our dedicated full-time aviation grant administrators manage the entire process required to secure funding. Grant applications, reimbursement requests, supporting documentation, and submittal of required FAA forms can rapidly consume the already overextended staff of even the largest airport. We prepare applications and all other required federal and state paperwork associated with planning, engineering, and construction projects. All that the sponsor has to do is sign in the proper locations, and C&S takes care of the rest. Our clients receive on-time and regular reimbursements from the FAA and state-level agencies. We administer the entire grant process for many of our airport sponsors, conducting regular programming meetings with FAA Airport District Office personnel, and working closely with FAA headquarters and regional staff.

Navaids and Electrical Systems

Our specialized navaids and electrical systems engineers have designed installations for all types of airfield lighting and navigational systems, including runway and taxiway edge lighting; LED lighting; in-pavement edge, centerline, and touchdown zone lights; guidance signs; visual aids such as REIL and PAPI systems; and instrument landing systems. These projects have included all related electrical power distribution, controls, equipment installations, and stand-alone airfield electrical buildings. In addition, we design emergency power systems, including stand-by generators and transfer equipment. We have designed airfield signage and marking plans and designed runway and taxiway lighting systems at nearly 100 airport facilities. We know the rules, what systems work best, and can expedite the process.


Our architects and engineers design additions, renovations, and new construction of a wide variety of aviation facilities, including terminal buildings, hangars, centralized receiving and distribution centers, ARFF facilities, equipment storage and sand storage buildings. Our in-house facilities group includes specialists in structural, mechanical, electrical, plumbing, site/civil, sustainability, space planning, and more. We can manage the planning, design, and construction of an entire facility or provide strategic services in conjunction with other team members. We have experience with many delivery methods, including design-build and public-private partnerships that can help reduce costs and get projects built more effectively.

Land Use and Market Strategies
