Expert field oversight ensuring quality installation and protecting your building envelope investment
Proper installation is absolutely critical to building envelope performance and longevity. Even the best design with premium materials will fail if not executed correctly in the field. Common installation problems include improper flashing details, inadequate fastening, damaged materials, sealant installation errors, gaps in continuity of air barriers and insulation, work performed in unsuitable weather conditions, and deviations from specifications and manufacturer instructions. Our construction observation and administration services provide independent oversight during construction to verify that roofing, waterproofing, air barriers, insulation, and cladding systems are installed according to specifications, manufacturer requirements, and industry best practices. This oversight typically prevents problems costing 10-50 times more than observation fees.
Professional construction observation requires specialized envelope knowledge that general contractors and architects may lack. Our consultants understand the nuances of various roofing systems, waterproofing applications, air barrier installations, and facade systems. We know where problems commonly occur, what installation errors look like, how weather affects different materials, and what questions to ask contractors. This expertise allows us to catch problems other observers miss, verify proper sequencing of work, ensure compatibility between adjacent systems, and distinguish between minor cosmetic issues and serious performance problems.
Different envelope systems require specific expertise and observation protocols. Roofing systems need verification of proper substrate preparation, insulation attachment, membrane installation, and flashing details with particular attention to penetrations, terminations, and drainage. Waterproofing systems below-grade and above-grade require verification of surface preparation, material compatibility, application rates, protection board installation, and drainage system components. Air barrier systems need careful inspection of membrane adhesion, seam integrity, transitions between materials, and penetration sealing. Insulation installations require verification of thickness, attachment, joint treatment, and continuity. Facade systems including curtain walls and window walls require observation of anchorage, glazing installation, weatherseal installation, and interface details.
Effective construction observation requires balancing quality verification with collaborative relationships. We work with contractors, not against them, to achieve quality results. Our approach includes early communication of expectations and standards, prompt identification of concerns when corrections are easiest, practical recommendations recognizing field realities, respectful professional interactions, and recognition of good work when we see it. This collaborative approach encourages contractors to maintain quality standards while giving owners confidence in work quality. We maintain independence representing owner interests while recognizing that contractors want to deliver quality work when expectations are clear.
Comprehensive documentation is essential for construction observation providing permanent record of conditions, supporting warranty claims if problems develop, demonstrating due diligence for liability protection, and tracking contractor performance. Our reports include narrative description of observed work and conditions, identification of deficiencies with specific location references, photographic documentation with clear labels and annotations, recommendations for corrections or further investigation, tracking of previous deficiencies and their resolution status, and summary assessments of overall installation quality. This documentation protects owners and provides clarity for all project stakeholders.
How often should envelope installations be observed?
Frequency depends on complexity and risk. Critical systems like waterproofing may require full-time observation. Roofing typically needs 2-3 visits per week. Less critical work might need weekly observation. Key is observing during critical phases when problems are most likely and verification matters most.
What's the difference between observation and inspection?
Observation is ongoing oversight during installation focused on compliance verification. Inspection is typically point-in-time examination of completed work. Observation catches problems during installation when correction is easy; inspection finds problems after work is complete.
Does observation replace the architect's construction administration?
No, observation complements architectural CA by providing specialized envelope expertise. The architect remains responsible for overall project administration; the envelope consultant focuses specifically on envelope system installation quality.
How much does construction observation cost?
Costs typically run 3-8% of envelope construction costs depending on project size, complexity, and observation intensity. A project with $1 million in roofing work might budget $30,000-$80,000 for observation—a small fraction of potential failure costs.
