Overview of Firestop Inspection and consulting service
Our Firestop inspection services are designed to verify that firestop systems are installed correctly and comply with relevant codes and standards. This is crucial for maintaining the integrity of fire-rated assemblies.
Our role as a third-party inspector is to provide an unbiased assessment of firestop installations, ensuring that they meet all necessary regulations and standards.
Overview of EIFS (Exterior Insulation and Finish System) Inspection & consulting Services
Our expert team provides thorough inspections of EIFS (generic term such as Dryvit in Korea) installations to identify potential issues such as moisture intrusion, structural integrity, and compliance with building codes. We utilize advanced technology and industry best practices to ensure your property is protected and maintained to the highest standards.
Overview of Air Barrier Inspection & consulting Services
What is an Air Barrier?
An “air barrier” is a combination of materials designed and installed in such a manner in order to drastically reduce or even stop the flow of air into and through the building enclosure. The air barrier of a building is an “air barrier system”. The air barrier system is comprised of “air barrier assemblies”. Air barrier assemblies are comprised of “air barrier materials” and “air barrier accessories”.

Evaluation of Building Envelope Performance on cooling and heating loads
Evaluating the performance of a building envelope in terms of cooling and heating loads is crucial for energy efficiency and comfort. The building envelope includes the walls, roof, windows, and foundation, which separate the interior environment from the exterior.
Renewable Energy Consulting
Renewable Energy Consultants work with clients to minimize or eliminate the environmental impacts of their operations. We are conducting environmental impact assessments, suggesting ways to reduce companies’ carbon footprints, identifying which company operations use the most energy, and recommending solutions for better energy distribution
Interior Design
Our team of experienced interior designers is dedicated to creating beautiful, functional environments that reflect your unique style and meet your needs. Whether you’re looking to redesign your home, office, or commercial space, we offer personalized solutions tailored to your vision.
What We Offer
we provide comprehensive inspection services designed to ensure quality, safety, and compliance across various industries. Our team of certified inspectors utilizes advanced techniques and equipment to deliver accurate and reliable assessments
Firestop Inspection Service offered:
- Inspection and Compliance: Conduct thorough inspections of firestop systems in new construction, renovation projects, and existing facilities to ensure compliance with fire codes and standards (ASTM, ISO, IFC guideline, UL guid information and Firestop manufactureer detailed requlations and manuals)
- Technical Review: Review Construction Drawings and other technical documents to verify that firestop installations meet design specifications.
- Field Inspections: Execute field inspections(visual inspection and destructive sample testing)and assessments of firestop installations, documenting findings and ensuring corrective actions are taken when necessary


EIFS Inspection Service offered
- Non-Intrusive Inspections: offer non-intrusive inspections, which do not require damaging the building’s exterior. This method is less disruptive and still effective in identifying moisture issues
- Moisture Probe Inspections: specialize in using moisture probes to assess the moisture levels within the EIFS, providing a more detailed analysis of potential problems
- System Integrity: examines the overall condition of the EIFS, looking for any damage, cracks, or sections where the system might be at risk. Detecting and resolving problems early can help avoid more significant and expensive repairs in the future.
Air Barrier Consulting offered:
- Expert Guidance: provide expert guidance on best practices for air barrier design, installation, and material selection based on the specifications of the United States Army Corps of Engineers (USACE).
- Performance Testing: conduct tests to measure air leakage and ensure compliance with energy efficiency standards.
- Problem Resolution: help identify and resolve issues related to moisture infiltration and air quality.


Evaluation of Building Envelope Performance on cooling and heating loads
- Energy Modeling Software: Tools like EnergyPlus, eQUEST, or TRACE 700 can simulate building performance under various conditions, allowing for detailed analysis of heating and cooling loads.
- Manual Calculations: For simpler evaluations, manual calculations can be performed using methods outlined in ASHRAE standards or the Manual J calculation for residential buildings.
- Life Cycle Assessment (LCA): Evaluating the environmental impact of materials and construction methods over the building’s life can also inform decisions about the building envelope.
Renewable Energy Consulting offered:
- Data Analysis: Gather and analyze energy usage data to identify areas for improvement.
- Energy Management Plans: Develop and implement energy management plans tailored to client need
- Compliance: Ensure that clients comply with environmental legislation and standards.
- Project Management: Oversee renewable energy projects from conception to completion, ensuring they meet budget and timeline requirements.
- Client Collaboration: Educate clients on renewable energy options and the benefits of sustainable practices.


Interior design
- Personalized Design Solutions: Tailored interior designs that reflect your unique style and enhance the functionality of your space, whether residential or commercial.
- Expert Guidance: Our experienced team provides professional advice on space planning, color selection, and furniture choices to create cohesive and inviting environments.
- Sustainable Practices: Commitment to eco-friendly materials and design practices, ensuring that your space is not only beautiful but also environmentally responsible.
