Transportation Engineering
Donohue Engineering's roadway design experience encompasses both new construction and reconstruction projects. The projects range from resurfacing of local streets to new roadway construction and intersection design. This work involves roadway condition surveys and assessments to the design of new full depth pavements and storm drainage systems. Stormwater runoff analysis is routinely completed to demonstrate the design of new collection systems or to recommend upgrades to an existing systems to alleviate flooding conditions. Over the past years, Donohue Engineering has prepared construction plans and specifications for the following types of projects:
- Residential Roadway
- Municipal Roadway corridors
- Retail and commercial developments
- Roadway Resurfacing and reconstruction
- Roadway Intersection Design
- Bridge and box culvert replacement
- Highway Access Permits
Hydrologic and Stream Hydraulic Analysis
Donohue Engineering provides hydrologic and stream hydraulic analysis on many of its projects. Stormwater hydrologic analysis is performed on all site planning projects to analyze increases in runoff and best management designs to calculate aboveground or belowground detention/infiltration basin designs. Stream hydraulic analysis is used in determine the effects of projects on downstream water surfaces for bridge replacement projects and also to determine flood plain limits. Donohue Engineering has obtained numerous NJDEP Flood Hazard Permits for various types of projects.

Construction Management
Donohue Engineering provides construction inspection services for its roadway and site development projects. Construction inspection services are offered to assure the contractor's conformance with the construction documents. Construction inspection is also provided as a separate service ranging from full-time inspection to part-time inspection support.
Construction Quality Control is necessary when tasked to oversee construction done by others. We control construction quality by preparing construction control plans, by preparing project specific checklists to inspect vendor shop drawings, and by preparing review forms to evaluate the contractor’s work and to determine if it complies with contract documents. We also prepare “punch lists” to ensure if the final work is complete and verify field tests. Interim payments are approved based on work completed.
Donohue Engineering is able to oversee every phase of a project, including construction. We assure that the final project is in accordance with plans and specifications and that payments to the contractor reflect the work performed. Our staff of civil, construction managers, resident engineers, and field inspectors coordinate each stage of construction through completion. Services offered include:
- Administration of Bid Procedure
- Contract Administration
- Construction Cost Estimates & Reports
- Change Order Preparation & Review
- Progress Schedule Review
- Preparation of As-Builts
- Shop Drawing Review.
Sleepy Hollow Subdivision, Twp. of Jefferson, NJ
This project involved the redesign of proposed subdivision roadways to blend into the natural landscape of the project surroundings, including the design of roadway geometry and stormwater drainage facilities. Donohue Engineering analyzed the previous roadway designs and prepared enhanced design documents. Construction Inspection services
