The Mid-Atlantic Precast Association (MAPA) recently announced that one of its producers, High Concrete Group, has received industry honors for an office building project in Philadelphia, PA. The Precast/Prestressed Concrete Institute (PCI) presented High Concrete with two awards, including the 2016 Design Award: Best Office Building and the 2016 Design Award Specials: Harry H. Edwards Industry Advancement Award. Both honors were for their four-story office building project at 1200 Intrepid Avenue in the Navy Yard in Philadelphia. The project proves that precast concrete enables the most innovative architectural designs while providing a highly energy-efficient and durable envelope. PROJECT OVERVIEW The building was designed by Bjarke Ingels Group (BIG), a Danish architectural firm that has long relied on precast to achieve form and function in their designs. “We came very quickly to the idea that precast concrete would be a great way to achieve our goals on this project,” says Kai-Uwe Bergmann, principal at Bjarke Ingels Group (BIG), the architect on the project. One of the most prominent features of the building is the white precast concrete façade, which dips dramatically away from the walkway along the eastern edge, then tips back out again, much like the buildings in a Dr. Seuss story. “One of the key design challenges was to create that curved façade from precast panels,” says David Bosch, design team leader for High Concrete Group, the precaster on the project and one of MAPA’s producers. The curved load-bearing design was achieved by assembling flat, traditional precast concrete panels to form a complex faceted geometry. An interlocking structural system was embedded within the panels to eliminate the need for traditional precast concrete spandrel panels. “The resulting façade creates an aesthetic versatility that is unique to the project,” Bosch says. The design breaks away from traditional architecture to better engage with the local surroundings, says Bergmann. “In many cases, architects design big, boxy buildings that could be placed anywhere and don’t connect directly to the site.” He argues that the curved white façade, and deeply reflective windows in this design were inspired by the city’s rectangular city blocks and the adjacent circular park that sits just in front of the building. It also echoes the geometries of maritime architecture and nearby waterway. “You would really be hard-pressed to place this building anywhere else other than where it is, due to how it connects,” Bergmann says. “We like to think about a building beyond its borders and look at how it interacts with its neighbors and the open spaces around.” PRECAST SOLUTION Along with being visually inviting, the owners wanted the building to achieve LEED Gold certification, which led to several sustainability measures enabled by the use of precast concrete. The thermal benefits of the precast façade lowered projected heating and cooling costs, contributing 7 of the 60 total LEED points for overall energy performance. The panels were also created using local raw materials and recycled content less than 60 miles from the project site, minimizing the greenhouse gas emissions related to transport and adding more LEED points to the total. “While the concrete production requires a larger carbon footprint initially, it is a material that will have a long life span and can be recycled if needed,” Bosch adds. Finally, the precast concrete façade solved the fact that the building’s steel structure was designed to carry only lateral loads, which meant the precast concrete façade had to transfer the gravity loads directly through the precast concrete panels to the foundations. To achieve this, the engineers designed a structural steel system embedded into the precast concrete panels. Pockets were formed into alternating panels at the spandrel level to allow the interlocking of each panel during installation. “All the gravity loads are transferred from any given panel to the adjacent panel on either side until they reach the foundation,” Bosch explains. “In order to prevent a progressive collapse in the event that one connection should happen to fail, each panel also has a safety backup connection.” For video content and a project photo gallery, visit the 1200 Intrepid Project Profile on the MAPA website.

The use of building information modeling (BIM) has provided a means of increasing total project quality, providing accurate quantity take-offs, and improving scheduling, consequently diminishing total project contingencies and costs. Although BIM is a recent development, a lot of research has been conducted in order to further enhance the capabilities of BIM in design and construction. However, there has been very little research done so far on the effect that BIM has on sustainable construction practices. Hence, the goal of this research is to investigate the perceptions of the use of BIM for sustainable design and construction among designers and constructors. A survey was developed and administered through the Internet to determine the existing trends of BIM application in general as well as its use as a tool in sustainable design and construction. The survey results indicated that although the majority of the respondents believed that sustainable design and construction practices were of importance within their company, most still believed that sustainability was not a primary application of BIM and that project coordination and visualization were instead more important. Although BIM is perceived as a multidisciplinary tool, problems with interoperability continue to persist among the various BIM applications in the industry. In terms of project delivery methods, the majority of the survey respondents believed that design/build and integrated project delivery (IPD) are the optimal project delivery methods to integrate BIM as a sustainability tool. Although BIM is still a recent development, as more design and construction professionals understand the potential benefits offered through its use, BIM will become a vital tool for sustainable design and construction. © 2013 American Society of Civil Engineers.

During commissioning of a large data center, while switching medium-voltage circuit breakers without any appreciable load, several potential transformers failed catastrophically. A detailed investigation, including a computer simulation, was performed. Ferroresonance produced by switching transients associated with opening and closing the vacuum breakers was determined to be the cause. The analysis also determined that the close-coupled power transformers were also in jeopardy. Field inspections involving grounding improvements coupled with solution simulations were made. High-speed switching transient measurements were performed to verify the analysis and the surge protective device solution (arresters and snubbers). This paper walks the reader through problem recognition, simulation, field measurements, and solution implementation. Special focus will be made on the field measurement verification. © 1972-2012 IEEE.

The recently completed 40-story office tower at 250 West 55th Street in Manhattan demonstrates the best in innovative structural design and use of 3-D coordination tools for design and construction. This paper describes the integrated process that was followed and some of the challenges that were met along the way. It will be of interest to design professionals and others interested in integrated construction processes. The integrated 3-D process started with the use of Revit from the Schematic design stage, and was followed through the design, procurement, and construction phases, with all major sub contractors producing 3-D or 4-D models. These models were carefully integrated by the general contractor and enabled savings in the schedule, reduction of field conflicts, and reduced project risks. The progress of the project was complicated by a suspension of construction for two years after completion of the foundations. This paper describes some of the unusual steps taken to manage this process and allow for an accelerated schedule upon restart of construction. © 2014 American Society of Civil Engineers.

Practice Periodical on Structural Design and Construction | Year: 2014
To protect the nation's surface waters from sediment-laden discharge, the proper selection, design, application, installation, and maintenance of erosion and sediment control practices on active construction sites are imperative. These practices will be required to comply with new, stricter regulations applied by the EPA to control high sediment concentrations of storm water discharge from construction sites. One mean of controlling sediment-laden discharge is through the use of sediment basins. The purpose of this paper is to report results from a survey conducted to determine the state of the practice for sediment basin design, construction, maintenance, and inspection techniques used by state highway agencies (SHAs) nationwide. The survey consisted of 68 possible questions in six categories: (1) background and experience, (2) design, (3) construction, (4) maintenance of sediment basins during construction, (5) inspection and monitoring, and (6) lessons learned. A total of 37 responses (74% response rate) out of 50 SHAs were received and analyzed. The summary of the survey, including lessons learned, allows knowledge and experience to be transferred to practitioners that may have little or no experience with using sediment basins on construction projects. The survey shows that the typical design life of a sediment basin is between 6 months and 2 years; the generally accepted minimum storage volumes among most agencies is 252 m3/ha (3,600 cu ft/acre) of disturbed area draining to the basin, and 13 agencies use flocculant additives to enhance the efficiency of sediment basins. © 2014 American Society of Civil Engineers.

A field-scale data collection plan to monitor and evaluate the performance of a sediment basin design was developed and implemented using portable automatic stormwater samplers, flow modules, a rain gauge, and inflow weirs. The design configuration consisted of a skimmer as the primary dewatering device, three coir baffles installed inside the basin, polyacrylamide flocculant blocks and ditch checks in the inflow channel. A sediment basin built on a highway construction site in Franklin County, Alabama, U.S. using the aforementioned design configuration was monitored over 16 rainfall events from 15 November 2011 to 6 February 2012. The basin effectively removed sediments during the early stages of construction when the correct type of polyacrylamide flocculant blocks was used, e.g., 97.9% of sediment removal after a rainfall event on 16 November 2011. It is difficult and challenging to dose sediment-laden stormwater inflow with an exact amount of flocculating agent across all runoff producing events since rainfall is a stochastic variable. Based upon results from this study, it is recommended that a minimum volume of 251.9 m3/ha of contributing drainage area be used to sufficiently size a basin, which is still significantly under-designed for a 2-year, 24-h storm event in the southeast. This paper presents challenges and lessons learned regarding sediment basin design, monitoring, and performance that are beneficial to future studies. © 2015 by the authors.

An abundance of research focuses on the collective performance and motivations of the TEAM in BIM coordination and execution. The team, however, consists of trade partners with different motivations and sophistication. Trade partners whose product is directly fabricated from 3D models, such as mechanical and steel contractors, are highly sophisticated in BIM. Their models tend to be accurate and vetted for constructability as their profitability depends on quick onsite assembly of prefabricated items. Trade partners whose work installation is not directly fabricated from 3D models tend to have less accurate models that are not vetted for constructability. Non-constructible elements included in BIM are waste as they do not bring value to the intermediate or end user. More perniciously, these models are a presentation of inaccurate information in a highly detailed form, leading to the perception of accuracy and the incorrect detailing of adjacent assemblies. This paper uses case studies of BIM implementation in the San Francisco Bay Area to analyze model accuracy and implementation by trade and identify best practices in team alignment. This analysis is used to propose a framework for enforcing model constructability based on the basic tenets the Last Planner System™. Beyond project controls, this paper investigates natural alignment of trade interest in constructible models. Specifically, if a trade partner's profitability is increased through the use of model-based layout or increased off-site fabrication, the model will consequently be more accurate, benefiting the larger team. Therefore, this paper also discusses the advantages of intrinsic motivation to reduce variability of trade models between coordination and the field, and proposes methods to achieve this future state.
