What is MACP and what it includes

Kiwa T2 provides Maintenance Hole Condition Assessments in accordance with NASSCO's Manhole Assessment Certification Program (MACP), a recognized industry standard for the consistent evaluation and coding of maintenance hole and chamber conditions. NASSCO's MACP program was developed to provide standardized condition assessments that help asset owners identify, prioritize, manage, and rehabilitate underground infrastructure assets. 

Our inspections evaluate structural and operational conditions within maintenance holes and chambers. Using inspection technology and digital reporting tools, our team documents defects, infiltration, corrosion, structural deterioration, and other observable conditions that may affect asset performance and service life.

Frequently asked questions

What is a MACP inspection?

A MACP inspection is a maintenance hole condition assessment completed using NASSCO's standardized inspection and defect coding methodology for manholes and chambers. 

What types of defects can be identified?

Inspections can identify structural deterioration, infiltration, corrosion, cracking, displaced components, debris accumulation, and other observable maintenance or operational issues.

What is the difference between MACP Level 1 and Level 2?

Level 1 inspections are typically screening-level assessments, while Level 2 inspections provide more detailed assessment and defect coding information. 

How are inspection results delivered?

Results are typically provided through digital inspection reports, condition coding databases, photographs, videos, and supporting documentation suitable for asset management programs. 

Can the information be integrated into asset management systems?

Yes. Inspection data can be incorporated into GIS, asset management databases, engineering drawings, and infrastructure planning workflows. 

When should a maintenance hole condition assessment be completed?

Condition assessments are commonly completed as part of municipal asset management programs, rehabilitation planning, land development projects, pre-construction investigations/post-construction investigations, and infrastructure due diligence initiatives.
