This guide is intended for use by public works managers who find themselves encountering the world of historic preservation.

The Preservation Economic Impact Model 2.0 software allows for the calculation of the total economic effects of historic preservation; these encompass both the direct and multiplier effects.

The goal of this project was to disseminate advanced information on historic preservation documentation and assessment utilizing the most “cutting edge” technology available.

Soiling of limestone caused by air pollution has been studied at the Cathedral of Learning on the University of Pittsburgh campus. The Cathedral was constructed in the 1930s during a period of heavy pollution in Pittsburgh, PA.

Termites are a significant structural pest in the United States, costing the public nearly $1.5 billion in damage each year.

The objective of this study was to develop a test method to measure the hardness of masonry mortars with a pendulum hammer.

Investigators from the Nelson-Atkins Museum of Art undertook this project to determine if worn-off or illegible hallmarks on silver and gold works of art could be imaged using scanning acoustic imaging techniques.

A study was undertaken to determine the feasibility of renovating and upgrading an original condition window to the extent that its thermal performance would be equivalent to a window using replacement sash or window inserts.

On the cover, view of the cedar roof trusses at the monastery of St. Catherine’s at Mt. Sinai, Egypt, built between 548 and 565 to commemorate the supposed site of the miracle of the burning bush.

Herein, basic Conservation and Preservation concepts would be pragmatically explained and illustrated, utilizing, for acclaratory purposes, case studies of preservation projects in Puerto Rico and the Caribbean.

Careful examination of the photo reveals the presence of the large Y-shaped iron yoke typically used by Robert Smith at the junction of the kingpost with the collar beam and hammer beams.

The assessment of unreinforced masonry structures is difficult to undertake in practice.
