When something goes wrong on a structural masonry project the fault usually lies in ambiguities, contradictions, or lack of detailing in the contract documents. The primary reason for coordination between architects and structural engineers is to provide clear directives, with sufficient detail, to the contractor so the building can be built correctly. According to the AIA Architect's Handbook of Professional Practice, the architect is responsible for coordination.

Masonry Coordination: A Checklist

  1. This checklist highlights some potential problem areas that both architects and structural engineers should be aware of during the design of a project. Masonry unit material type and strength
  2. Mortar type and specification method
  3. Specified masonry compressive strength
  4. Wall construction: collar joints; mortar bedding; extent of grouting; coursing; bond patterns; structural continuity; and shelf angles
  5. Wall placement
  6. Movement joint types, configuration, and location
  7. Locations and sizes of openings
  8. Flashing locations
  9. Reinforcement size, location, and placement
  10. Connectors: ties; anchors; and fasteners

The goal of coordination between architects and engineers is to eliminate all ambiguity from the contract documents.
