The objective of this project is to identify the risk factors taken into account in the pricing of an insurance contract for a construction site. This project aims to synthesize the quantitative approaches used in practice and presented in academic research for the pricing of home insurance and commercial insurance. Then, we aim to identify the preventive measures that can be taken to reduce the impact of different perils in the insurance of a construction site in wood or other.

The overall goal of this project is to enable the use of cross laminated timber (CLT) to construct commercial and other non-residential buildings in High Velocity Hurricane Zone (HVHZ). The 1992 Hurricane Andrew exposed the shortcomings of existing building codes. Recognizing this shortcomings, the Florida Building Code (FBC) incorporated new enhanced provisions which specifically require that the entire building envelope, including the wall and roof systems, must be impact resistant in HVHZ. Currently, CLT is not in the database of a list of building envelope products that comply with the HVHZ standard. The specific objectives of this project are (1) to qualify PRG-320 compliance CLT panels for HVHZ standard by conducting FBC debris impact and wind pressure cyclic tests; (2) to conduct education and outreach sessions to promote the use of CLT in HVHZ, and (3) to identify possible construction projects that may utilize CLT as the building envelope and promote the use of CLT in those projects. The test results generated in this project will be used specifically to gain HVHZ building code approval.
Mass timber construction in Australia and New Zealand uses three main materials—laminated veneer lumber, glue laminated timber and cross-laminated timber (CLT). This article focuses on the use of mass timber in nonresidential construction—the use in single-family homes and apartments is not considered. In Australia and New Zealand, mass timber building technology has moved from being technologically possible to being a feasible alternative to reinforced concrete and steel construction. It has not taken over a large market share in either market and, as such, has not been a disruptive technology. The major changes in this market in the past 5-10 yr in Australia and New Zealand have been the development of new industrial capacity in CLT and the acquisition of computer controlled machining equipment to facilitate prefabrication of wooden building components. The development of new codes and standards and design guides is underway. The drivers of future growth in market share are expected to include more clients putting a higher weight on the various environmental benefits of building in wood, reduction in the real and perceived professional risk for builders and architects specifying mass timber construction, and fuller participation in the supply chain for timber buildings (from design to construction) by timber building specialists. Government policies to encourage the use of timber may also be helpful. Engineers and architects will continue to learn—through experience—how to optimize building construction methods to take advantage of the specific features and qualities of timber as a construction method.
