Techno is expanding its field inspection team and is seeking a skilled Blasting & Underground Construction Inspector to support a high-profile transportation infrastructure program in Baltimore, Maryland. This is a long-term field assignment supporting complex underground construction activities tied to a major rail corridor improvement effort.

The initial assignment is expected to run approximately four months, with a strong possibility of extension based on project needs. The role is full-time and field-based, with a consistent on-site presence required.

In this position, you will be embedded in the field, serving as a critical quality and compliance resource during excavation and blasting operations. You will work closely with contractors, engineers, and inspection staff to help ensure underground work is executed safely, efficiently, and in accordance with approved plans.

• Observe and verify controlled blasting activities from planning through execution, including drilling patterns, explosive placement, protective measures, and post-blast conditions
• Monitor underground excavation progress, including muck removal, rock stabilization, ground support installation, and structural elements
• Confirm that construction activities align with safety requirements, approved methodologies, and technical specifications
• Review and validate blast documentation such as shot logs, vibration data, and monitoring reports
• Maintain detailed daily inspection records and clearly document deficiencies or deviations from approved plans
• Coordinate with contractors, field engineers, geotechnical staff, and project leadership to resolve construction or safety concerns
• Inspect related civil and structural components, including concrete placement, liners, waterproofing, and support systems
• Participate in field meetings and provide real-time insight on blasting progress, sequencing, and constructability considerations

• Minimum of 5 years of hands‑on experience inspecting underground construction with direct involvement in blasting operations
• Strong working knowledge of controlled blasting practices, tunnel excavation techniques, and underground support systems
• Experience interpreting construction drawings, blasting plans, and technical specifications
• Familiarity with vibration monitoring, blast impact controls, and environmental mitigation measures
• Prior experience on large‑scale rail, tunnel, or underground infrastructure projects strongly preferred
• Blasting-related certifications or equivalent demonstrated field experience are a plus
• OSHA 10 or OSHA 30 certification preferred; additional underground or blasting safety training is a plus
• Strong written and verbal communication skills with the ability to clearly document field conditions
• Ability to work extended hours, including nights or weekends, and perform duties in active underground environments
• Bonus: Prior experience working on projects for major transportation agencies, including the Maryland Transit Administration (MTA) or similar agencies, is a plus
