David Andersen, PE - Senior Material Engineer
David has been providing leadership and technical expertise in the materials lab since 1994. A civil engineer, Dave has been the Assistant Laboratory Manager, the Laboratory Manager and is now the Senior Materials Engineer. He develops mix designs, prepares bids, manages testing and inspection projects, reviews specifications, and troubleshoots issues that develop in the field. Dave is well respected in the construction industry and is often called by owners and contractors to assist with construction issues. Dave is involved in every project where Alaska Testlab provides special inspection and testing services, including numerous projects all over the state.

David’s mix design expertise is in remote Alaska projects using local aggregates, if possible, meeting durability and strength requirements. He understands how to work with the suppliers/contractors to develop aggregates and mixes that will meet the project specifications. A key component to a successful concrete mix is matching the capability of the contractor and the equipment with the project requirements. Dave has prepared 3000 to 8000-psi structural concrete throughout Alaska including Red Dog Mine, Kodiak, North Slope, Adak, St. Paul, and Ketchikan. He created the first successful SCC mixes using local aggregates in Alaska as part of a North Slope project. Lean concrete mixes, sand slurries, shotcrete, and Roller Compacted Concrete are some of the additional mix designs. Dave’s expertise is also with bituminous asphalt mix designs having recently produced a mix design using local aggregates for paving of the Red Dog Mine runway. His knowledge of materials in Alaska is second to none.

Oscar Lage - Laboratory Supervisor
Oscar has over 16 years’ experience in materials testing and geotechnical engineering, Oscar started his career in the United States in a soils testing lab in Louisiana becoming familiar with ASTM and other procedures. Oscar moved to Alaska where he became involved in geotechnical engineering. He has logged several hundred test holes statewide in support of a variety of projects to include roads, airports, towers, bridges, wind turbines, and docks. He is proficient with analyzing data, developing recommendations, and writing reports. Now back to materials testing, Oscar oversees all laboratory testing. He trains technicians on the various procedures, manages sample in processing, works with Dave on mix designs, and is responsible for calibrations and verifications of all laboratory equipment.

Evelyn Voliva - Office Manager
Evelyn has been working in the construction materials testing and inspection field since 2006. She began with dispatching the field technicians and inspectors and from there took charge of the nuclear densometers as a Radiation Safety Officer, and all logistics required to move people and equipment around the state. She handles the billing, invoicing, and ordering. Evelyn’s ability to multi-task has her responsible for the concrete lab testing. She has established the laboratory steps each technician follows when bringing in concrete for strength testing, works with staff to ensure the samples are logged in appropriately, and observes the break data. She enters in break results, and reports results to the clients. When she’s not making sure the office runs smoothly, she will assist with laboratory testing and training other technician. She is familiar with ASTM, AASHTO, and WAQTC standards and ensures tests are run using appropriate methods. Evelyn is ACI certified in concrete strength, aggregates, and laboratory testing, and WAQTC certified.

Ashley Kampsen - Administrative Assistant/Payroll
Ashley is a new addition to the office staff but no stranger to organization, efficiency and the day to day operations of a field oriented industry. Ashley handles an array of office duties from reception to scheduling to payroll. Ashley is an efficient multi-tasker who assists Evelyn with maintaining the complex scheduling and providing administrative support that is critical to our successful operations.


Alaska Testlab is proudly home to the best Special Inspectors in the state. Highly respected in the industry for their integrity and knowledge, these ICC-certified professionals work with contractors and owners to ensure projects are constructed in accordance with the International Building Code, plans, specifications, and local requirements. Our inspectors are experienced and knowledgeable in regards to construction practices, codes, and Alaskan conditions; some have been providing these services in Alaska for over 20 years.
An experienced Special Inspector can be an asset on construction project by helping to maintain the project schedule. Minor non-conformance issues can often be resolved immediately with little to no delay. For more significant issues, it may be beneficial to have the special inspector directly interact with the structural engineer and municipal inspector to determine the most efficient and simplest resolution to keep the project moving.

Quality comes with investment in people and a desire to be the best. Our inspectors practice continual improvement with certifications, continuing education, seminars, conferences, and in house training. All of them hold multiple certifications from ICC and are most are certified by one or more of the following; ACI, WAQTC, NICET, and CESCL.

At Alaska Testlab, our goal is to see projects completed on time, on budget, the public’s safety addressed, and constructed in accordance with the plans and specifications. We do this by working collaboratively with all parties; owners, contractors, building officials, and the design team. We are proactive in finding solutions to issues and working towards a common goal.

Material technicians provide testing services both in the field and in the laboratory. Our technicians are trained in both arenas to ensure an understanding of materials, material behavior, and performance. Technicians are involved in all facets of the construction process. In the field, they collect samples of materials before use, they perform density testing of soils and asphalt during construction, test concrete for air, slump, unit weight and conformance to the specifications. They make concrete cylinders to test for strength. They observe backfill operations for both proper materials and lift thicknesses. During paving, they work with the contractor to ensure the asphalt is placed properly and compacted to standards. In the laboratory, technicians verify material properties for comparison to standards. This is done on soils, aggregates, rock, concrete, masonry, grout, asphalt, and topsoil.

To ensure quality our technicians are certified by ACI and WAQTC. Many of them are training to be inspectors and are licensed by the Municipality of Anchorage to provide inspections on at least one construction element. For quality, dependability, knowledge, professionalism and experience, Alaska Testlab’s materials technicians are second to none.
