On behalf of Howard S. Wright and DLR Group, we are pleased to submit for your consideration The Portland Building, designed by Michael Graves and built In July, 2016, the City of Portland engaged the design-build in 1982 as administrative offices for the City of Portland, team of Howard S.

The building was later placed on the National Register of to holistically address the building’s issues by designing Historic Places as a building of “exceptional importance,” and constructing a building renovation that would meet the but it currently faces problems with its structure, exterior, City’s requirements for the Project. The City chose to use and operational systems that repairs alone cannot address. a progressive design-build delivery model for the project To protect and preserve this major public investment, the including a Collaborative Project Delivery (CPD) method City has initiated a $195 million project to reconstruct the that brings the City and the DBR team into the design and Portland Building by the end of 2020. The City will create construction process in a way that makes best use of each an adaptable building that will last another 50-100 years, member’s unique knowledge and skill sets to increase value, providing a productive work environment for employees and reduce waste and maximize efficiency. a welcoming space for community members.

The building is approximately 360,000 SF plus basement. In addition to the repair and replacement scope of work outlined above, the City outlined the following goals for the Project: • The Project will seek, at a minimum, LEED™ Gold certification • The Project should maintain its historic elements and character and should seek to ensure the Portland Building’s place in Portland’s history, • The Project should result in a significantly improved efficiency and functionality of the building as a workplace, • The Project should result in reduced maintenance and operational costs for the Portland Building. • The Project should utilize comprehensive strategies to support and contract with Disadvantaged, Minority-Owned, Women-Owned, and Emerging Small Businesses (“DMWESB”) and support the hiring of minority and women workforce in the trades.

EXECUTIVE SUMMARY
Dec 2, 2016 / PHASE 1 REPORT / 7 VISIONING
The project team held two day-long interactive visioning sessions with City of Portland Bureau Directors and other key City stakeholders. The first session was held in August to introduce workplace concepts and establish a consensus on operational and workplace approaches that should be explored by the DBR team. The second session was held in September to present and discuss concepts that validated the approach established in the first session.
The City of Portland’s vision for interior planning and workplace concepts needed to support the City’s goals to serve the public well and to become an “employer of choice.” In order to envision an appropriate design concept to align with those goals, our team focused the visioning sessions on both the public experience and the employee experience. Developing the project vision through this lens allowed us to stay focused on how we should plan spaces and set design criteria within the iconic building.
Each vision session led to a series of goals and priorities that the design team used as guiding principles when making decisions about the organization and intention of the interior PUBLIC FACING SERVICES & AMENITIES EMPLOYEE WORKPLACE SHARED CONFERENCING environment.

These floors also include “historic” planning assumptions for the private office and workstation spaces preserving Michael Graves’ original design intent for standards. These new standards are based on the desire the two level entry lobby area and elevator lobbies.

Space has also been provided for environment that provides appropriate employee shared the City to display and incorporate public art as well as items space as well as a variety of right-sized focus / collaboration of historic interest should that be desired. spaces to allow staff a choice of where to work depending on the task. In order to accommodate these new spaces, the individual office and workstation sizes have been reduced and the allocation of individual to shared space reallocated. Typical “Workplace” Floors
There are eleven typical “workplace” floors (Levels 4 – 14) The typical “workplace” floors are located on Levels 4 – 14. which are able to accommodate City of Portland staff. Levels The floors have standardized locations for built-rooms and B, 1, 2, 3, and 15 are able to accommodate public customer shared support spaces. An optimal ratio of open work space service and meeting areas, shared employee support spaces, to built-rooms and standardized room sizes will allow each shared meeting rooms, storage, and select staff functions. bureau to customize their workplace by how they choose The project scope of work is based on 1,332 FTE’s which is the to assign rooms and furnish open areas.

The 1,332 consistent planning approach for the typical floors helps FTE scope can be accommodated on 8.5 of the typical floors. reduce move costs as bureau’s requirements change over This leaves 2.5 typical floors available for future department time and helps provide way-finding that is intuitive to navigate growth and/or additional staff coming into the building from from floor to floor.

This may allow a large portion of the building to be re-occupied starting in Q1 of 2020. Select tenant floors would still be under construction into Q2 of 2020, but the ongoing activities would be relatively minor in nature, similar to tenant improvements occurring on an on-going basis in most office buildings around town. This would allow for normal operations to resume for many of the bureaus in the renovated building, while other bureaus would move back to the building in Q2 of 2020. The feasibility of this phasing will be studied further as the project progresses.

/CITY OF PORTLAND / HOWARD S. WRIGHT / DLR Group 18 /THE PORTLAND BUILDING RECONSTRUCTION PROJECT SEISMIC UPGRADE IMPROVEMENTS
One of the primary requirements of the project is to increase the performance level of the building and to reduce the hazard to occupants during a seismic event. As originally designed, the lateral load-resisting system consists of 3” reinforced concrete slab diaphragms (integral with the waffle slab) that transfer lateral loads (wind and seismic) to the vertical elements. The vertical elements consist of reinforced concrete moment frames and reinforced concrete shear walls.
Recent studies by KPFF and others have identified deficiencies in the existing lateral force resisting system relative to current code requirements that will be addressed as part of this project. The main deficiency is that the existing exterior walls resist much more load than the concrete moment frames during a seismic event but do not have sufficient strength to resist the anticipated seismic loads.The discontinuity of the existing exterior walls at the 3rd floor requires that the vertical seismic forces in the walls transfer to the columns supporting them, and that the horizontal seismic forces in the walls transfer through the floor diaphragm. Both the existing columns and the floor diaphragm are not sufficient to resist the additional seismic loading created by this discontinuity.
We are providing an optional seismic upgrade to the building. Building codes currently recognize that it can be technically and economically challenging to retrofit an existing building, and that often these buildings have a shorter life expectancy than that of a new building. Therefore, the building codes establish a lower requirement for existing buildings than they do for new buildings. For the Portland Building, the baseline seismic criteria has been upgraded by using the new building hazard levels such that the expected seismic performance of the retrofitted building would be SEISMIC UPGRADE consistent with that of a new building constructed to current building codes.
