Structural Round Timber follows existing workflows that architects, builders and engineers are accustomed to. We can help you with your project throughout the specification process. Here’s how building professionals can engage Original Mass Timber Maine throughout the design and construction process:

Project Conception:
Original Mass Timber Maine can assist owners and architects as they discuss project requirements by providing precedents and helping to manage owner needs, wants and budget.

Schematic Design:
As the architect prepares rough sketches in Schematic Design to show the general arrangement and visual characteristics of the project, OMTM can work with our partners to assist with the preparation of renderings to help owners and architects visualize the project, making the owner approval process simpler. 

Design Development:
As the architect prepares more detailed drawings to illustrate other aspects of the proposed design, OMTM and our partners can provide outline specifications, detailed species information, design, drafting, shop drawings, detailed connection info, and other project management services. 

OMTM and our partners can provide the level of engineering service your EOR requires. We are happy to fully engineer the SRT on your project, or simply provide the connection info, reactions, or sizing requirements, per the requirements of the EOR. 

Product Selection:
Partnering suppliers will search their inventory for the trees that fill the required design and aesthetic specifications for the project. The trees are regionally sourced and fabricated, and then shipped to the project site. 

After a contractor/builder/GC has been selected and hired, we can provide project installation questions. Installation instructions are provided for each project. Optional installation supervision and/or full product installation services may be available depending on the project size and scope.

Heavy timber has been used in construction for hundreds of years. Today, new technologies allow us to quickly assess material properties, grade round timber for its structural capabilities, assign it design values and scale it through a fabrication process that rivals both traditional timber framing and modern engineered wood products. 

Structural Round Timber (SRT) is recognized by the International Building Code (IBC) as heavy timber and is suitable for a broad range of applications. SRT can be used in wood construction types III, IV, and V construction, and Type II with variances. The approval of new tall mass timber code provisions in the 2021 IBC allows greater opportunities for mass timber construction than ever before.

Sustainably managed forests fulfill a critical role in society and are an important part of all of our lives. Forests provide society and our local communities numerous benefits that we enjoy every day. Everywhere we turn, there is something we use that either directly or indirectly comes from the forest. 

Sustainably managed forests provide the diversity of habitat that creates the home for numerous species of mammals, birds, reptiles, insects, and more.  This is accomplished by providing protection and cover, nesting sites, migratory corridors, down woody debris, dens, vernal pools, and foraging opportunities, just to name a few.

Increasing urban development across the nation has only added to the importance of the recreational opportunities provided by sustainably managed forests.

Forests provide an avenue to escape from the stresses of life and to connect and experience nature. Opportunities such as hiking, fishing, hunting, bird watching, snowmobiling, snow shoeing, camping, and many other active and challenging activities are all provided by sustainably managed forests. 

Sustainably Managed Forests Help Keep Natural Resources Clean
  • Air

Forests improve the quality of the air we breathe by removing particulates from the air such as pollen, smoke, ash, and dust.

Forests also remove other harmful pollutants from the air, such as nitrogen oxides, ammonia, and ground level ozone, all which can all cause health issues in humans.  

  • Soil

Soil is an important component of a managed forest ecosystem and contributes directly to a forest’s diversity of plant and tree species.

Forests help prevent soil erosion by reducing the impact of heavy rains on the forest floor.  Tree roots provide support to the soil and help keep soil in place on steep slopes. Forests also help maintain soil fertility through natural nutrient cycling.

  • Water

Managed forests play a vital role in maintaining water quality by collecting and filtering rainfall, cleaning and purifying it before that water enters our streams, rivers, lakes, and groundwater.

Forests also hold the soil in place, preventing erosion and the introduction of sediment into our waterways.  

Healthy, Working Forests Are a Climate Mitigation Solution

Sustainably managed forests are healthy forests.   Healthy and productive forests capture carbon from the atmosphere and store it in the form of tree trunks, leaves, branches, and roots.

When trees in a managed forest are harvested, they are manufactured into long-lived products that continue to store carbon, such as lumber and paper.  Harvest residues and milling byproducts (such as limbs, tree tops, sawdust, and wood chips) are also carbon beneficial.  They can be used to produce clean, renewable energy, reducing society’s reliance on fossil fuels. 

Following a timber harvest, sites are reforested through both natural regeneration and planting, restarting the carbon capture and storage cycle.

The US Green Building Council’s (USGBC) Leadership in Energy and Environmental Design (LEED) program is designed to encourage the design and construction of buildings that utilize sustainable building materials, conserve water resources, and are energy efficient. LEED Certification ensures that a building is energy and resource efficient. SRT can complement other materials to help achieve certification. 

For more information on the USGBC LEED program, please visit: 

The International Living Future Institute’s Living Building Challenge is a certification program and philosophy intended to encourage the creation of a regenerative built environment. Living buildings are defined as: Regenerative buildings that connect occupants to light, air, food, nature, and community; Self-sufficient and remain within the resource limits of their site; Create a positive impact on the human and natural system that interact with them. SRT can complement other products to help achieve certification.
