Timber is coming to tall building construction. The International Building Code is set to include all-wood high rise construction, up to 18 stories, in its 2021 edition. Depending on fire resistance, allowable heights from 85 feet to 270 feet would be available to architects and engineers. Indiana incorporates many parts of the IBC into the building code and can accept or reject these new construction regulations once issued.
Wood is a carbon-neutral building material and can perform as well or better than concrete or steel. Testing by the Federal ATF and Department of Agriculture indicated that mass timber structures provided more fire protection than currently required by the IBC for conventional tall building construction.
We can expect vigorous lobbying by the American Wood Council as the states debate the new code provisions.
As expected, the Portland Cement Association thinks this is a bad idea.
