Transportation

CR Engineers, Inc. (CRE) has extensive history in street and roadway lighting design, providing numerous such designs for the various cities throughout Arizona including: ADOT, City of Phoenix, Scottsdale, Tempe, Glendale, Mesa, Chandler, Gilbert, and Casa Grande. We have expertise in AGI-32, and Genesys II programs. Our use of this software allows us to produce a lighting model that helps us optimize light distribution, conserve energy, and maintaining safe light levels in public areas. The graphic representations substantially aid in visualizing the effectiveness of the lighting design at a glance. It only takes a few minutes to produce the lighting models, so several computer runs using different input data (height, spacing, type of luminaries, etc.) can be cost-effectively produced to help optimize our designs. Combined with our other CAD and Micro Station software packages, we are prepared to perform any lighting design task to meet the projects needs.

Aviation

CRE has substantial experience in this field of Aeronautical Ground Lighting (AGL) systems as well as electrical design for additional airport facilities. Our AGL experience encompasses electrical airfield lighting vault design, runway, apron, and taxiway lighting, Automated Weather Observing Systems (AWOS), airfield guidance signage, and other NAVAID systems. CRE also has extensive experience in designing AGL control and monitoring systems as well as standby systems. Over and above designing AGL systems for an airport, our experience includes designs for terminal buildings, hangars, perimeter fences and access gates, and airport parking facilities. We can provide electrical design for any airport building, which may require interior lighting, security communications, and/or fire protection systems. At CRE, our design philosophy is governed by the essential requirement for AGL systems to be safe, dependable, and provide maximum efficiency and ease of maintenance for the respective airport, while maintaining minimal downtime of airfield electrical systems during construction.

Photovoltaic Power Systems

CRE has the expertise to provide complete photovoltaic power system designs from sizing of solar modules to engineering the connectivity to the conventional electrical panel. All of our electrical and solar designs meet the requirements of the National Electrical Code, Electrical Utility Standards and specific City Standards. We can also provide our clients with a cost benefit analysis that includes all current and state cost incentives, solar options, power output, payback times and related construction costs for each photovoltaic option provided.

Recreation

CRE can offer the following engineering services for your recreational facility: design and specifications for electrical power distribution, lighting, public address and security  systems, computer aided photometric calculations, and design of lighting controls. Our extensive experience in the lighting design of soccer and baseball fields, skate parks,  volleyball, basketball, tennis and racquetball courts, children’s playgrounds, pathway and parking lot lighting, and electrical designs for aquatic centers is unsurpassed by any other firm in the Phoenix area. Our innovative design approaches have won CRE numerous recognition and awards. We understand the importance of creating an inviting and safe area for the public to enjoy.

Buildings / Special Systems

CRE has an extensive variety of expertise in providing electrical and special system designs for buildings, including commercial, industrial, municipal, church, and medical facilities. Energy management, electrical designs for the healthcare industry, and special system designs including fire alarm, security and CCTV systems, and telecommunications using fiber optic technology are also part and parcel of the CRE skill set. Our team attends frequent training classes and seminars in order to remain updated with the latest advances in technology concerning all life safety system design applications. We are dedicated to providing our staff with frequent educational opportunities in all National Electrical Code changes, and we can renovate and update systems to correct Electrical Code violations. We are experienced in forensic electrical engineering, light level verification, and other electrical testing of existing conditions.

Water/Wastewater Electrical Instrumentation and Control Design

CRE has performed numerous electrical and instrumentation and control systems design for industrial water and wastewater facilities. Our experience includes designing electrical and instrumentation systems for wastewater treatment plants, lift stations, water treatment plants, well pumping facilities, booster stations, and reservoirs for a multitude of municipalities including: Phoenix, Glendale, Mesa, Chandler, Avondale, and Surprise, just to name a few. CRE can provide power distribution design for low, medium, and high voltage systems for complex motor controllers, such as variable frequency drives and solid state starters. We will also design and specify any required instrumentation used for controls, such as ultrasonic level sensors and differential pressure transmitters. Our team is highly experienced in designing Supervisory Control and Data Acquisition Systems (SCADA) utilizing various mediums including radio, phone, and fiber optics. We can integrate Programmable Logic Controllers (PLCs) into our design for a completely automated system.

Construction Administration

CRE can also provide full electrical construction management and inspection services. We have a highly trained staff of dedicated electrical inspectors to provide numerous services during construction. Our extensive experience and knowledge of National Electrical Code, IBC, and multiple Arizona city code requirements enable us to fulfill all project needs. Services include: load and meter testing and diagnostics; submittal review; site observations, punch list preparation, and record drawings. CRE can provide electrical design and construction services for UPS, standby and emergency generator design; medium voltage distribution design; inspections and renovations of existing systems to correct National Electric Code (NEC) violations; ground testing; and ARC flash analysis.
