Design & Engineering
Practical, constructible design for transportation and aviation infrastructure
Overview
CHIN provides civil design and engineering services focused on aviation and transportation infrastructure. Our designers translate complex requirements into clear, coordinated plans that are shaped by how projects will be built, phased, and maintained – while accounting for the operational constraints owners face during construction.
Our design approach is grounded in practical delivery experience. By integrating constructability, phasing, and coordination into the design process, we help owners advance projects efficiently from plans to construction.
Capabilities
Aviation Infrastructure Design
Designing airfield infrastructure for construction in operating airports.
CHIN provides aviation infrastructure design services supported by IDOT prequalification and informed by FAA standards and airport-owner requirements. Our teams develop airfield and aviation-related designs that account for operational continuity, constructability, and coordination within active airport systems.
- Runway and taxiway configuration, rehabilitation, and phasing
- Airfield pavement design, markings, and signage
- Aviation-related roadway geometry, alignments, and site design
- Stormwater management, drainage, and hydraulic analysis
- Utility coordination and utility design within secure airport environments
- Landside aviation infrastructure, including parking configuration and access
- ADA/accessibility and pedestrian circulation considerations
- Maintenance of Traffic (MOT) and aircraft movement phasing
- Plan, specification, and estimate (PS&E) development, including support for alternative delivery methods
CHIN incorporates constructability, access planning, and phasing directly into aviation design documents to support efficient construction while airports remain operational. Structured QC/QA reviews ensure designs are coordinated, compliant with applicable standards, and ready for implementation.
Transportation Design
Designing roadway and transportation infrastructure with delivery in mind.
CHIN delivers transportation Phase I and Phase II design services aligned with IDOT and agency prequalification requirements, supporting roadway, freeway, and multimodal transportation projects from rehabilitation through major reconstruction. Our teams develop coordinated, constructible plans that account for agency standards, existing conditions, and construction phasing requirements.
- Roadway and freeway geometry, alignments, and cross sections
- Rehabilitation and reconstruction design for roads, streets, and corridors
- Bridge rehabilitation and replacement support
- Stormwater management and drainage
- Hydraulic and floodplain analysis
- Utility coordination and conflict resolution
- Maintenance of Traffic (MOT) and construction phasing
- Traffic control and signal-related design elements
- Plan, specification, and estimate (PS&E) development
Throughout design, CHIN incorporates constructability and phasing considerations to support efficient construction and minimize impacts during implementation. Disciplined QC/QA reviews at each milestone ensure documents are coordinated, compliant, and ready to be built.
Elements of a Successful Partnership
Delivery-Informed Design
We design with an understanding of how projects will be constructed and phased.
Operational Awareness
Our plans account for the need to maintain access and operations throughout construction.
Disciplined Quality Control
Structured QC/QA processes ensure coordinated, compliant, and reliable design documents.
Responsive Collaboration
CHIN works closely with owners, reviewers, and delivery teams to resolve issues early and support timely decision-making.
