Geotechnical

The conditions below the ground surface cannot be easily predicted without a thorough subsurface exploration and proper evaluation of the data collected. It is essential that the exploration program be planned based on the local geologic conditions, the potential environmental factors, the geotechnical engineer’s experience, and the intended use of the property.

Our firm provides geotechnical recommendations that result in cost-effective site development and foundation design/construction, and a reduced likelihood of construction delays caused by unforeseen conditions.

Property Condition Assessments

Property Condition Assessments or PCA’s are important for Clients seeking to know the condition of a property or real estate they may be purchasing, leasing, or simply maintaining. NOVA’s PCAs are performed in accordance with ASTM E2018 and can identify the following:

  • Existing deficiencies
  • Provide guidance on system repairs
  • Replacements
  • Projected costs of future maintenance and repairs

NOVA’s PCA reports include components such as:

  • Landscape
  • Hardscape
  • Civil
  • ADA Compliance
  • Parking lots/decks
  • Windows, doors, roofs
  • Building envelope
  • Finishes
  • MEP
  • Structural

Building envelope & roof consulting

The performance of the building envelope is critical for the structural integrity, durability and effective operation of any structure. Performance failure due to uncontrolled moisture intrusion, heat or air flow can compromise a building. From pre-construction consulting, mock-up and jobsite testing, fabrication and jobsite quality control inspection, to post-construction investigations, assessments and surveys, NOVA’s proven professionals are known for their ability to recognize and troubleshoot problematic glass and glazing, roofing and waterproofing issues before such adversely impacts budgets and schedules.

  • Review wind tunnel testing and analysis of results
  • Develop preliminary roofing and waterproofing design
  • Prepare performance specifications and details
  • Analyze alternate cladding, roofing and waterproofing systems
  • Review of bid and contract documents
  • Assist with bid analysis and subcontractor selection
  • Develop and/or review Operations and Maintenance Manuals

Assessment and Remedial Consulting

  • Perform due diligence/pre-purchase inspections, assessments and evaluations
  • Conduct water intrusion investigations, which includes remedial repair plan development
  • Assess glass and glazing, roofing and waterproofing system failures and develop remedial repair plans
