Civil engineering is the broad class of engineering dealing with public works projects such as roads, sewers, drainage work, water mains, and structures like homes, retaining walls and bridges.  

Since 1976, NTI has employed the largest team of private-sector civil engineers on the North Olympic Peninsula.

Our engineering services are often related to the provision of home sites and/or amenities for the citizens and visitors to the North Olympic Peninsula. Stormwater design is typically a major part of these services.

The following list of engineering services will help explain how we invest in our community.

Water Supply

  • Source: Water supply begins with a well, spring or existing supply; most rural water comes from well or spring systems.
  • Storage: Water storage is usually accomplished in above-ground reservoirs which need to be sized correctly, structurally sound and located upon stable ground.
  • Distribution: The delivery of water requires properly sized pipelines that meet government regulations.
  • Planning: The state requires that water systems have current comprehensive plans. NTI works with water purveyors to maintain these documents.

Sanitary Sewers

  • Sewer Pumps: As more homes are built in the community, many are located in areas difficult to serve with conventional sewers. NTI’s engineers are knowledgeable and experienced in designing both large and small sewer pump systems.
  • Municipal: City sewage solutions usually involve deep-trench gravity sewers, which require strict control of depth, grade, and coordination with other underground facilities.
  • Separation of Combined Sewers: NTI staff has considerable experience, both in the City of Port Angeles and elsewhere in designing solutions to the inundation of sanitary sewer systems with stormwater.

Storm Drainage

  • Water quantity: Increasing the amount of paving or roof area can increase the amount of runoff.  Downstream homes or property may be affected. NTI routinely designs stormwater control facilities to meet complex government regulations and local needs.
  • Water quality: Increased runoff often results in a decrease in water quality. NTI regularly designs storm water quality control facilities, often using Low Impact Design (LID) and other techniques to meet government regulations.

Subdivision of Land

  • Our civil engineers routinely provide support for our staff of designers and surveyors in their processing of subdivisions.  Typically, engineered plans for stormwater, sewage, water supply and access will be needed before the new subdivision will be allowed.  This in- house support helps expedite the project and minimize the cost of the project.

Streets, Roads & Parking Lots

  • Individual clients and/or cities and counties often need streets, roads and parking lots designed. This task involves the design of the paving surface and base, the geometric design of the facility, the design of stormwater quantity and quality controls and attention to the amount of excavation

Soils and Earthwork

  • Soil conditions are extremely important to the successful completion of a project. NTI’s geotechnical staff is capable of evaluating existing soil conditions and making recommendations for solving specific site problems. This includes foundation engineering, landslide identification and remediation, and design of earthen structures.

Site Development

  • The development of a site involves all of the disciplines identified above in a coordinated action toward a common goal.

Construction Management and Inspection

  • Proper construction management will save money. For example, the coordination of inspections will help reduce contractor down time and waste.  NTI’s construction inspection team is the most experienced on the North Olympic Peninsula.

Computer-aided Drafting and Design

  • The NTI technical staff is trained in the latest generation of computer-aided design and drafting techniques.
