  • Public Realm Design Manual Version 2.1 March 2019
    Public Realm Design Manual A Summary of District of Columbia Regulations and Specifications for the Design of Public Space Elements Government of the District of Columbia Version 2.1 - March 2019 Muriel Bowser, Mayor II Majestic views of national monuments, leafy residential streets, and wide sidewalks in commercial areas... these are iconic images of Washington, DC. Much of the daily routine of District residents, workers, and visitors takes place in settings like these. This is where we walk to school, wait for the bus, talk to neighbors, walk the dog, window shop, or sit outside in a café to drink a cup of coffee. Having such an extensive network of public space enhances the quality of life for our residents and visitors, and ensures that the city has the foundation to become a more walkable and sustainable city. The District’s public space is a valuable asset worthy of our stewardship and - with the help of all residents and property owners – is one if the unique features that makes our city great. The Guide to the District of Columbia’s Public Space Regulations is a resource for learning about the importance of the District’s public space, the regulations that guide its use and form, and the rationale behind them. Property owners are required to maintain the public space adjacent to their property, so it is important that these ideas are understood clearly. Beginning with the L’Enfant Plan and continuing to today, Washington, DC has a notable history of using public space to define the city and give character and grace to neighborhoods.

  • 2020 Amendment to the Comprehensive Master Plan NIH Bethesda Campus January 13, 2020 Need for Projects
    2020 Amendment to the Comprehensive Master Plan NIH Bethesda Campus January 13, 2020 Need for Projects: Surgery, Radiology, Laboratory Medicine Addition (SRLM): The Clinical Center (CC) at the NIH leads the global effort in discovering tomorrow’s cures and training today’s investigators. It is essential that the CC has state-of-the-art patient care, treatment and diagnostic facilities that support this effort. The proposed project is focused on developing a facility that supports both NIH and new congressional medical research initiatives to improve the nation’s health and strengthen NIH’s biomedical research capacity in close proximity to the Clinical Research Center. The Ambulatory Care Research Facility (ACRF) opened in 1982 and houses the departments of Perioperative Medicine, Interventional Radiology, Radiology & Imaging Sciences and Laboratory Medicine. These departments involve some of the most advanced and technology dependent cutting- edge programs supporting NIH’s Translational Research initiatives. Since the ACRF opened, over 38 years ago, biomedical research and its supporting clinical programs have rapidly evolved, influencing the criteria for space and infrastructure systems. The rapid evolution of equipment (changing every 3-5 years) has also had a direct impact on both space requirements and the utility systems that support them. The existing facility has not kept pace with modern surgical, imaging, and clinical laboratory facility requirements. Hospital surgical suites are typically replaced every 20 years to keep up with the latest technological advancements in operating room equipment and techniques. The most recent “Building Condition Index” conducted by the NIH has the ACRF in the POOR category. Some of the major deficiencies include the following: 1.

  • Shallow SEM Tunneling with Limited Clearance to Existing Structures: Design, Construction and Observations
    Shallow SEM Tunneling with Limited Clearance to Existing Structures: Design, Construction and Observations Hong Yang . Mott MacDonald Derek Penrice . Mott MacDonald Walter Klary . Gall Zeidler Consultants Vojtech Gall . Gall Zeidler Consultants ABSTRACT The excavation and initial lining has just been successfully completed for the Downtown Bellevue Tunnel using Sequential Excavation Methods (SEM). The soft ground tunnel, approximately 2,000 feet long and 38 feet wide with very shallow cover, faced several unique challenges and design refinements that were managed and implemented dur- ing final design and construction. This paper provides an overview of the tunnel con- struction, then focuses on three design refinements; tunneling under an existing utility trench with 4 feet of vertical clearance, tunneling within 4 feet of an existing building basement, and eliminating pipe canopy and replacing 12-foot thick overburden soil with controlled low strength material (CLSM) at the tunnel’s north portal. Details of the analysis, design, and construction of these design refinements, together with the comparisons between the predicted and observed settlement results are presented. INTRODUCTION East Link is a 14-mile extension of the existing Sound Transit light rail transit sys- tem from downtown Seattle, across Lake Washington, to the cities of Mercer Island, Bellevue and Redmond. The Downtown Bellevue Tunnel (DBT) is the only tunnel on the extension and, as its name suggests, extends through the downtown of Bellevue with relatively low cover between the at-grade East Main and Bellevue Downtown sta- tions (Figure 1). The DBT consists of 250-foot-long south cut-and-cover portal struc- ture, the 1,983-foot-long SEM tunnel, the mid-tunnel access shaft and connecting adit, and the 200-foot-long north cut-and-cover structure.

Welcome and Introductions (CI International) Marc Gravallese (CI): Welcomed the group to the meeting. Group: (Participants introduced themselves. Attendance list attached.) II. Project Updates- Global Project Updates (GSA) Jim Fortinsky - GSA – Pile work is being done to support the U.S. Coast Guard Building and foundation work is being done throughout the building. Soil excavation has been completed and garages are being excavated. Slab and foundation work has been started on the north side of garage. The first six adaptive reuse buildings are being abated right now and upon completion will be turned over to Grunley Construction to start construction. Building abatement for the Phase 1 adaptive reuse buildings is anticipated to take 90 days. Utility tunnel work NTP is anticipated to occur in December and the Perimeter Security Fence NTP has been given to Balfour Beatty. We continue to coordinate work between Clark and Grunley. GSA has been directed not to open Gate 3 at this point, therefore, we are not moving forward with this piece at this time. As soon as the project team receives further guidance on this item we will discuss with the Consulting Parties. Pepco has begun bringing in their new electrical line right now. There is a lot of crossing of work in that area which requires a great deal of coordination. We are fencing up the protected landscape areas. We are also trying not to have too much activity on the site as we will be crowded in a very short period of time.

  • A Case Study for Up-Down Design and Construction Methodology for a High-Rise Development in Los Angeles, California
    SEAOC 2008 CONVENTION PROCEEDINGS A Case Study for Up-Down Design and Construction Methodology for a High-Rise Development in Los Angeles, California Jason Thompson, Associate KPFF Consulting Engineers Portland, Oregon Chris Zadoorian, Principal GeoDesign, Inc. Anaheim, California Abstract 60,000 square feet. It is anticipated for completion in 2008. The building footprint occupies the entire site and is rectangular in Over the past few years, numerous high-rise projects have been shape. It is bounded on the south and east sides by 12th Street initiated in downtown Los Angeles. In most cases, at least one and Grand Avenue, respectively; by an alleyway on the west and often two or more subterranean levels are constructed. side; and by a recently completed 11-story residential tower Conventional construction sequencing would consist of with one subterranean level, immediately to the north. See shoring installation, mass excavation, and construction of the Figure 1 below. below-grade structure all prior to construction of the building superstructure. For a high-rise project currently under construction in downtown Los Angeles, an alternative sequence, referred to as ‘up-down’ (or ‘top-down’) was used to reduce the duration of the overall construction schedule. Up-down sequencing typically allows the construction of the building superstructure in tandem with mass excavation and construction of the below-grade levels. The subject project includes a 23-story tower over three subterranean levels and has a building footprint of approximately 60,000 square feet. A modified up- down sequence was implemented in which the installation of basement walls and below-grade foundations and the initiation of superstructure preceded mass excavation and basement floor construction.

  • Right of Way Improvement Standards
    RIGHT OF WAY IMPROVEMENT STANDARDS PHILADELPHIA STREETS DEPARTMENT Carlton Williams Commissioner Richard J. Montanez, P.E. Deputy Commissioner of Transportation Stephen Lorenz Chief Highway Engineer June 2015 Last Rev: N/A Forward Over the past several years, the Streets Department has undergone some transformative changes. From the Great Recession of 2008, we have entered into a time of major construction and development. With this “New Boom”, demands for a better understanding of the technical and regulatory requirements of the Department have grown dramatically. These demands have occurred concurrently with an increasing need for enforcement of Federal, and State laws, as well as a series of laws and initiatives adopted by the City of Philadelphia. In addition to seeking to fulfill the obligations defined within the Philadelphia Home Rule Charter, and the Philadelphia Code, the Streets Department has recognized the need to ensure compliance with the Americans with Disabilities Act (1990), and the Underground Utility Line Protection Act, PA Act 287 (1974, and as revised), all within a framework defined greatly by Philadelphia Code §11-900 (Complete Streets). The purpose of these Right of Way Improvement Standards is to gather the standard requirements of the Streets Department into a single source. Much of the content of this publication derive from established Streets Department resources, as well as standards established, or influenced, by our sister departments, and partners with the Commonwealth of Pennsylvania and the U.S. Government. As a living document, this Standard is subject to periodic revision, as the needs of this great City continue to grow, and new practices and technologies within our street network become available.
