LEARNING OBJECTIVES

1. Understand the Commonwealths public procurement process, guidelines, sequence of documentation and bidding with regard to implementing a new structural system.

2. Understand the advantage of cross laminated timber as a method for reducing the carbon footprint of construction.

3. Understand the opportunities of exposed cross laminated timber as an interior finish strategy, contributing to the health and well being of occupants. Understand the inherent complexities that go along with exposing building structure and systems.

4. Understand the structural considerations necessary when working with the cross laminated timber.

CONTEXT / Cross Laminated Timber Brief History 1. Engineered wood composed of layers stacked perpendicular to each other for added structural rigidity in both direction.

2. First developed in early 1990’s in Austria and Germany 3. First adapted to IBC in 2015.

4. Can be used for multiple building elements.

CONTEXT / Priorities of The Commonwealth

1. Witnessed the inherent benefits of using CLT at the Olver Design Building at UMass Amherst.

2. The growing acceptance in the building codes for the use of mass timber.

3. Possible use for multiple building elements - floor, ceiling, wall, and roof construction.

4. The sustainability benefits of being a low-carbon alternative to steel, concrete, and masonry in many applications.

5. Improvement of interior experience with the warmth of natural wood.

CONTEXT / Origins Of The Project - DUA PROJECT HISTORY - JUNE 2015 EOLWD (DUA) RFP for a new office space lease with DCAMM’s Office of Leasing consolidating the Brockton Job Center with other offices.

Total needs 20,046 usable square feet (USF).

Existing building at 36 Main Street has 17,760 USF, shortfall of. 2,300 USF. For operational purposes, EOWLD strongly preferred a single floor layout as opposed to the existing 4-5 floors.

36 Main Street - Existing Building Summary: Constructed early 1900’s 29,600 GSF on 4 floors and a basement 7,500 GSF floor plate (not including basement) 1/2 acre parcel that including 38 parking spaces Steel and wood framed structure, brick and concrete façade Budget for this project determined to be $17M. Project would still leave DUA with a building that did not meet its needs.

ABX 2020 / Cross Laminated Timber and Public Procurement

CONTEXT / Origins Of The Project - DUA PROJECT HISTORY - OCTOBER 2016 The team was then directed to look at the feasibility of using the building at 226 Main Street.

Purchased by the Commonwealth from the City of Brockton in 2015 for use as a Downtown Higher Education Collaborative which was determined to be infeasible.

Sitting vacant prior to 2015 and was in a rapidly deteriorating condition.

226 Main Street – Existing Building Summary: Constructed 1927 22,700 GSF on three floors and a basement 9,700 SF footprint (1-3) 2,950 SF footprint (basement) ¼ acre parcel Steel frame and concrete deck construction, brick and terracotta facade

Demolition of 226 Main Street / Construction of new DUA building

ABX 2020 / Cross Laminated Timber and Public Procurement

CONTEXT / Origins Of The Project - DUA

01

Renovation of 36 Main Street for DUA – to better meet operational needs and address building deficiencies for DUA to remain and satisfy all consolidation needs. In this option, the existing building would be renovated to better meet DUA’s needs. Deemed infeasible due to the added cost of phased construction or temporary facility. Final product would not meet DUA’s programmatic needs.

ABX 2020 / Cross Laminated Timber and Public Procurement

CONTEXT / Origins Of The Project - DUA

02

Renovation of 226 Main Street for DUA – utilizing preserved façade with new office building construction.

Deemed infeasible due to hazardous materials present in existing façade and for lack of appropriate floor to floor heights for contemporary office building.

CONTEXT / Origins Of The Project - DUA

03

Demolition of 226 Main Street / Construction of new DUA building - Selected to meet DUAs programmatic needs. This determination resulted in an almost perfectly rectangular site ideal for CLT construction.

No cladding of steel beams 2. CLT wall panels eliminated due to fire code requirement of cladding 3. Glulam diagonal braces eliminated to forego variance process. Lateral system solved in more elegant way, integrated with architecture

Simple and Fast Installation The Beam Hanger System typically consists of two identical parts, one installed in the primary member and the other in the secondary member.

These components are pre-installed into the members using structural wood screws. Depending on the Beam Hanger type, the system could include other Typical Concealed Wood Beam Connection required installation hardware. For more information, see hardware section, pages 8 to 10.

CONCLUSION / Conclusions and Common Take-Aways

1. Owner must recognize the added value of using cross laminated timber from both a sustainability and experiential standpoint, and be willing to incur the added costs of research, design, and procurement for a relatively new product to this market.

2. Early and willing engagement with mass timber representatives by both the design team and construction manager is critical for determining the correct approach to documentation and bidding.

ABX 2020 / Cross Laminated Timber and Public Procurement

CONCLUSION / Conclusions and Common Take-Aways

3. The early timber bid package provides the necessary hard bid and still allows installer to join into the design process before construction documents are completed 4. Extensive coordination between design team construction manager during design, and subcontractors post bid is critical to achieving the aesthetic goals inherent to the use of mass timber.
