The newly opened Holgate Library in Southeast Portland has turned a modest 6,400 square meter facility into a 1971 facilities built into a 21,000 square meter community center to serve one of the most diverse populations in Portland.
The library, part of the bond measure of Multnomah County to revive the Portland's library infrastructure, is prominently used in the Southeast Holgate Boulevard with functions that are operated on all ages.
The project is a strong example of how the commitment of the community, the design of innovations and the establishment of sustainability create a built environment, in which the entire surrounding community serves in the coming years. The design of the building resulted from extensive input in the community due to focus groups, public meetings and surveys. Young people took part in a four -week virtual program called “Your Library, your voice” to design the first included teenager in the library in the system. The room was referred to as “at home away”.
Sustainability was of central importance for the building approach. The library uses a hybrid wood structure that reduced the CO2 footprint of the building by 61 percent compared to conventional steel and concrete structures. The ground floor has a denser column layout to support heavy book loads, while the second floor contains fewer columns for a more open design.
The mass wood frame uses a cross laminate wood (CLT) for floor and roofing, sticky-laminated wood (glulam) for the primary structural straps and kink brackets (diagonal steel elements) for lateral stability.
The building was developed to obtain a LEED gold certification and contains radiation floors for thermal comfort and a photovoltaic system on the roof to compensate for energy consumption.
The library has advanced amenities, including a large play and learning area for children, a committed teenage room, flexible programming rooms and the latest technology with high-speed internet. An outdoor plaza offers space for reading and conviviality.
The construction company Swinerton served as CM/GC and brought in his subsidiary Timberlab for the mass wood components. The project did not include any record -bearing injuries throughout the construction.
The project also emphasized the economic inclusion, whereby Swinerton implemented a project -specific program for the diversity of attitudes. The Swinerton project team also took on the role of mentors and led companies through the subtleties of the pre -construction and construction phases. In addition to the promotion of strong relationships and the support of their sustainable growth, Swinerton offers comprehensive training courses that included technical skills, project controls, budget management and project execution. The project and these efforts helped to acquire COBID certification. The Holgate Library project had a 25 percent diverse business goal (cobid) and reached 34 percent.
