This document provides guidelines for volunteers to count and categorize different types of concrete buildings. It lists various categories of buildings and infrastructure to count or not count, and notes some may have additional data available. The ultimate goal is to estimate the total number of buildings and concrete buildings in a city, both overall and pre-1980, which may vary from assessors' data by 10-20%.
What to Count
- 1. Concrete Coalition Toolkit Prepared by Dave McCormick and David Bonowitz
- 2. If in doubt, count it and note that you have counted it.

Concrete Building Types Count Data Concrete Frame with Masonry Infill X 1-Story Cast-in Place Concrete with wood Roof (including walls with pilasters) X Concrete Shear Wall with Steel Gravity Frame X Mixed Construction2 Do Not Count Data X Wood-frame residential on Conc. Podium Optional – Other Databases Available1 X Tilt-ups X Dual System with Concrete Shear Wall3 X X Parking Garages Buildings Whose Concrete Elements are Limited to Fire Walls Between Sections X Buildings Whose Concrete Elements are Limited to Basement or Retaining Walls X Includes horizontal additions of concrete as well as buildings with concrete lateral load systems in one direction only. 2 Do not need to make exceptional efforts to verify whether a building has a dual system or not, but if you know, don’t count it 3
- 6. Concrete Building Types Count Data Retrofitted Buildings4 X Buildings in Areas Scheduled for Redevelopment X Building-like Nonbuilding Structures5 Do Not Count Data X Abandoned Buildings Optional – Other Databases Available1 X X Nonbuilding-like Nonbuilding Structures6 Concrete Structures Supported on Piers or Wharfs over Water X Buildings used for storage – No Occupancy X 4 Obtain approximate retrofit date is possible. 5 Includes campanile, substation and pumping stations. 6 Includes silos, tanks, bridges, canopies, covered walkways and monuments. Do not include concrete block buildings without concrete walls.
