Characterization of glued-laminated timber supply in Chile
The rise of construction with wood in the world has its presence at local level, where there is great activity on this matter. The forestry institute (INFOR) actively participates in research projects carried out for the purpose of generate, and transfer economic, and technical information, which allow actors to make informed decisions to improve the development, and consolidation of construction with wood in Chile. In terms of economic information, for the first time the industry of wood engineering products is addressed, which is represented mainly by glulam (Glued laminated timber), whose supply is characterized in the present research. Thus, this study contributes to the decision-making process of private, and public actors involved in construction with wood; delivering an informed, and detailed analysis of the glulam in Chile; at the same time, the presentation of glulam industry profile aims to share this reality with the international interested community, and experts to gather opinions, and experiences about this industry’s contribution in wood construction.

Comparative research of single-family housing construction systems by construction cost using structural wood and other materiality
The wood construction massification in Chile has been considered in the last years as a strategic axis in forestry, and environmental policies, considering that this is a forestry country, the remarkable environmental contribution potential the use of this material has, and the necessity of reducing the housing deficit. In order to evaluate the development feasibility of a massive housing wood construction, with higher quality standards than the ones traditionally used, a comparative analysis is conducted in terms of construction costs based on 4 constructive systems: wood framing, post and beam construction system, galvanized steel, and confined masonry. The wood frame system is presented as the most competitive mainly due the wall, and roofing final cost, but also in the carcass work final cost; it is also more competitive in the construction final cost, but here the gasps are reduced. All evaluated systems have budgets that may be eligible for state subsidies. Among the keys to improve competitivity in wood construction is the diversification of lengths, and dimensions in structural products supply. In relation to the post and beam system, traditionally associated to higher value, and size, it is concluded that is possible to develop delimited footage projects, with low cost, which also allows a greater use of the system advantages in terms of the possibility to modify the house internal distribution.

Structural sawn wood production in the Chilean sawmill industry, data analysis from surveys carried out for 4 years
The sawmill industry produce around of 8 million cubic meters annually, setting Chile as the tenth world producer of sawn wood. Since Chile is a foretry country, the current sectoral policy has among its strategic axis the promotion of quality wood construction. From here it emerges the necesity of reinforce graded structural sawn wood supply, boosting this product demand by the construction industry. In this context, INFOR began to generates specific statistics on structural sawn wood (MAE), this activity accumulates four years of measurments. In the present research, it is presented the main results of the analysis of data obtained from these measurments, through surveying in the sawmill industry. To carry out the survey on MAE (structural sawn wood), sawmills with production higher than 10,000 cubic meters annually were selected, gathering information from a sample of 100 sawmills per year, from 2018 to 2021; these sawmills represents near of 80% of the sawn wood national production. Results indicate that the knowledge about MAE concept has just slightly increased during four years of measurments; while the interest of sawmill in participating in MAE production it is determined by the greater access to higher pirces, a more stable demand, and a greater reliability in logs availiability.

Estimating the glued-laminated timber demand in non-residential buildings in Chile
Glued laminated timber has taken center stage in recent years in Chile. The non-residential building sector is attracting the attention of local architects and builders, possibly due to the multiplicity of types of buildings, in which the attributes and advantages of this product are expressed. There is no record of the amount of glued laminated timber that is consumed annually in the country. The present study is a contribution to the knowledge of the demand, from the point of view of the potential that the non-residential construction market would offer. The main result indicates that, if all the potential non-residential area use glued laminated timber as a structural element, the associated demand would be in the range of 192 to 220 thousand cubic meters. This volume accounts for the enormous space that exists in the construction market to position this product, since production does not exceed 25,000 m3.

Using ARIMA models to project sawlogs and sawn wood prices in the Chilean construction materials market
One of the most remarkable factors when defining the materiality of a construction is the material cost. In this context, by having the tools to help reduce the uncertainty of wood cost will contribute to carry out projects with this material. The ARIMA models are management tools that have the potential to support projections in the short, and medium term. In the present research, the implementation of local ARIMA models were carried out in Biobío, La Araucanía, and Los Lagos regions, using as supplies the time series of radiata pine (Pinus radiata) sawn wood, and sawlogs prices, which have been collected periodically by the Forestry Institute (INFOR). The estimations on the implemented models had positive results in respect of validation data, with the exception of sawn wood prices from the four quarter of 2020, and part of 2021, which presented an unusual increase during the COVID-19 pandemic.
