Siting Considerations for Prefabricated Buried Open-Bottom Precast Concrete Bridge Structures

(Print PDH from the December 2023 issue of Informed Infrastructure)

Open-bottom buried bridges are structures built with side walls and a top that’s either flat or in an arc formation. With either configuration, the bottom is not constructed as part of the bridge structure, which provides a foundation design that’s separate from the bridge’s structural design. The structure sides support the surrounding soil, while the open bottom has the flexibility for a variety of site adaptations.

This feature is useful with existing streambed conditions where it’s essential to reduce site disturbance. Where the bridge spans over the streambed, the natural soils can be preserved, assisting in the sustainability of wildlife and fish passage. A buried bridge structure limits the exposed structural elements, reducing maintenance time and costs by protecting the bridge against exposure to de-icing materials. A prefabricated concrete structure is constructed at an offsite precast plant location and delivered to the site, reducing the overall construction time as compared with onsite conventional stick-built-type bridge structures.

Technology Improves Ease and Speed of Designing Infrastructure for ADA Compliance

(Print PDH from the December 2023 issue of Informed Infrastructure)

According to U.S. Census Bureau data from 2021, there are about 42.5 million Americans with disabilities, making up 13 percent of the civilian noninstitutionalized population. This group includes people with hearing, vision, cognitive, walking, self-care or independent-living difficulties.

For much of human civilization, engineers designed infrastructure through the lens of the non-disabled, with little regard for how certain aesthetic or functional features may affect or even become obstacles for those with disabilities. In 1990, the Americans With Disabilities Act (ADA) was signed into law, which extended civil rights protections to people with disabilities and looked to prevent discrimination against the disabled in the workplace and in public spaces. The law was amended with improvements in 2008.

This professional-development article will focus only on one aspect of engineering for those with accessibility needs: curb ramps that gently transition a pedestrian from a curb to a street or vice versa. And it will focus only on one particular project: the East Colfax Avenue Bus Rapid Transit (BRT) project in Denver.

Corrugated Steel Pipe and Structural Plate for Vertical Applications: Understanding Design, Applications and Practices
(Print PDH from the October 2023 issue of Informed Infrastructure)

Corrugated steel pipe (CSP) and structural plate products have been produced since the early 1900s and have since been expanded to a variety of applications. CSP and structural plate products are designed with a profile wall to provide a more efficient strength-to-material ratio. This strength, paired with its durability and dependability, has allowed it to be a versatile product since its inception.

A prevalent use for these products is vertical applications, which includes caissons for utility poles in electric transmission lines, bridge and building piers, wind-tower foundations, crane enclosures, utility sewer shafts, petroleum cellars (pits), general concrete forms, and more. These applications often are temporary structures used as forms or construction aids but not intended for long-term structural support. They can be constructed using CSP, structural plate or tunnel liner plate.

The Fundamentals of Stormwater Quality Regulations (Print PDH from the September 2023 issue of Informed Infrastructure)

Civil engineers working on land-development projects typically are hired to develop site plans and gain regulatory approval for those plans. In most urban areas, a stormwater management plan must be approved prior to construction. The purpose of each plan is to ensure the project is designed to minimize the amount of pollutants that are washed from a site during storm events and transported into downstream water bodies through storm drains as well as to reduce the peak flows and excess runoff volume that result from the creation of impervious surfaces. Therefore, engineers must understand the fundamentals of stormwater quality regulations, including why they were developed, how to find and interpret local stormwater quality regulations and design criteria, and how to find and use independently verified performance data to evaluate innovative stormwater control measures (SCMs) to meet regulatory goals.

Stormwater Maintenance: Legal Compliance and Environmental Benefits (Print PDH from the August 2023 issue of Informed Infrastructure)

Stormwater is a resource to be managed. Stormwater systems require maintenance to ensure they will continue to function properly and control flooding, provide water quality benefits, ensure public safety, meet regulatory requirements, and provide a return on the community’s financial investment. Management includes hydraulic, hydrologic, treatment or some combination of the three. The primary goal is to address pollutants such as Total Suspended Solids, trash and nutrients before they reach the receiving waters. Many methods and solutions can be used to treat pollutants and address the hydrologic changes development creates, including, but not limited to, detention filtration in green infrastructure. Stormwater systems range from large concrete storm sewers, roadside ditches and flood-control reservoirs to rain gardens and natural riverine systems.

Evaluating Minimum Cover Depths of Flexible Pipes Subjected to Tracked Vehicular Loads (Print PDH from the December 2022 issue of Informed Infrastructure)

Piping systems are typically designed with the service loads in mind. Many utilities are subjected to highway loads, so the design vehicle frequently reflects a vehicle described by the American Association of State Highway and Transportation Officials (AASHTO) design code such as an HS-20 or HL-93 truck. However, there are many other vehicular loads that the pipes will likely need to support as well. Many of these are loadings from vehicles used during installation of the utilities. Excavators, dozers, front-end loaders, roller compactors and other equipment are commonly used on projects that involve pipelines. Many times, these pieces of equipment are operating at cover depths less than the final cover that will support the highway vehicles. Contractors need to know how much cover is required to operate the various pieces of equipment they use on projects.

When we think of a steel mill, we might imagine a picture of dark skies, rusty exposed steel and billowing smokestacks. There is a long-held preconceived notion that steel mills are “dirty.” Not so! During the last 30 years, the steel industry has made major strides forward with modern technology and significantly reduced greenhouse gas emissions. In one sector of today’s steel mill, we will instead find cleaner and more controlled electric arc or induction furnaces, charged with increased amounts of scrap steel, less raw material and overall smaller production footprints. Steel mills are now surrounded by green landscapes, a sign of sustainability. Structural steel produced in the United States through this modern process contains an industry average recycled content of 93 percent. The most recycled material by weight in the world is steel, and it can be repeatedly recycled without the loss of metallurgical and engineering properties. For these reasons, steel is a premier green construction material and should be considered alongside any other material when designing for sustainability.

Integrating Engineered and Nature-Based Solutions for River Bank Stabilization (Print PDH from the February 2022 issue of Informed Infrastructure)

Palo Alto is the 13th-largest agricultural producing county in Iowa, with an estimated $468 million in crops and livestock reported in 2017. On average, each farm in Palo Alto County covers about 435 acres, and each acre is essential for the farm’s livelihood. Simply put, land is important and losing it to erosion is not an option.

The West Fork of the Des Moines River cuts diagonally through Palo Alto County, providing drainage for approximately 1,800 square miles of farmland. 485th Avenue and 425th Street intersect along the West Fork of the Des Moines River and are connected by the Kirby-Flynn Bridge, a historic pin-connected Pratt high-truss bridge dating back to 1881. During rain events, the Des Moines River often would flood in this area, causing erosion on an upstream bend and floodwaters to inundate the bridge, resulting in a more-than 24-mile detour for local travelers.

Design Considerations for Using Flexible Buried Bridges in Lieu of Conventional Bridges (Print PDH from the December 2021 issue of Informed Infrastructure)

Structural-plate buried structures consist of multiple metal plates that are corrugated, shaped to a specific curvature, hot-dipped galvanized (when made of steel), and bolted together in the field to construct large culvert or clear-span arch bridge crossings. After assembly, they are backfilled using granular soil to complete the bridge crossing. They are considered flexible structures that work via soil-structure interaction, where the structure and surrounding engineered backfill work together to support the design loads.

Structural plate has been in use for more than 90 years. It originally served as a large-diameter alternative to corrugated metal pipe (CMP) for use in hydraulic applications where CMP could not be efficiently built large enough to satisfy hydraulic requirements or where bottomless (arch- or box-shaped) structures were needed. Original corrugation profiles were relatively shallow (6” x 2” or 9” x 2.5”), which limited the available structural-plate span length.

Stream Crossing Replacement: A Case Study on Rural Hydraulics (Print PDH from the October 2021 issue of Informed Infrastructure)

Residents of urban and suburban areas of the country tend not to think much about how they travel to and from work, the store or a restaurant. However, those in rural parts of the country who live on a stretch of county roads with very few homes know that if it rains, the bridge may not be crossable.

Today, civil engineers typically build roads and highways in urban and suburban areas so they won’t be inundated with a rain event less than what’s considered a 100-year storm (Q-100), which means there’s a 1-percent chance the storm event will happen in any given year. When you live on a rural stretch of roadway, typically narrow with few other residents using the roadway, the design storm frequency the drainage structures will be unable to handle is much more common. In this example, the structure is designed to overtop the roadway during a three-year storm (Q-3), which means there’s a probability of the three-year storm event in one year = 1/F or 1/3 = 33.3 percent chance the runoff from the rainfall event will overtop the roadway. If you live down this stretch of roadway, you will be wondering if you can cross the drainage structure each time it rains.

Green Infrastructure Mimics the Natural Water Cycle(Print PDH from the September 2021 Issue of Informed Infrastructure)

The intent of green infrastructure (GI) is to mimic the natural water cycle during a stormwater event. Traditionally, when a site is developed, most runoff is directed toward a downstream drainage system and carried offsite. An undeveloped site allows infiltration and evapotranspiration, with some overland flow and runoff during heavy storms.

Green infrastructure provides decentralized Best Management Practices (BMPs) for treating stormwater by infiltrating it into the subsoil to reduce volume and flow, and doing so in smaller systems located throughout the site to treat water closer to the source.

The Fundamentals of High-Rate Biofiltration (Print PDH from the August 2021 Issue of Informed Infrastructure)

From California to Maryland, high-rate biofiltration continues to gain acceptance within the regulatory and engineering community as an acceptable alternative to traditional bioretention. These systems provide high treatment levels in a compact size (see Figure 1), making biofiltration feasible on sites where traditional bioretention is not possible. They have earned numerous agency approvals for meeting water-quality standards for post-construction best-management practices (BMPs). In addition, they benefit from being smaller in size, which saves valuable land space and reduces long-term maintenance costs compared to traditional bioretention.

Integrate Accounting and Project Management to Streamline Operations and Improve Profitability (Print PDH from the June 2021 Issue of Informed Infrastructure)

The term “project accounting” isn’t familiar to many architecture, engineering and construction (AEC) professionals because their firms revolve around meeting their client’s needs, the projects they’re awarded, and how those services are performed. In these types of service-based businesses, accounting often is a “back-office” consideration. But if AEC professionals want to run a better business, they need to perform accounting at a project level.

In effect, every project manager is a business manager: the CEO of his or her own little company. The company is the project, and AEC professionals should be held accountable for delivering what their clients expect—and to do so profitably. A lot of firms, however, don’t think about it this way. They don’t empower their project managers, nor make them accountable for the business side of their work. And why should they? After all, AEC professionals went to school to design and build incredible projects, not to run a business.

That’s where project accounting comes into play. By applying today’s business intelligence tools effectively, design and engineering firms can centralize and streamline the way they enter and use information for time tracking, billing, project management and accounting. And with recent advances in analytics tools and artificial intelligence, firms can leverage their software to transform data into actionable insights to support business decisions.

Composite Concrete Filled HSS: Design Considerations (Print PDH from the April 2021 Issue of Informed Infrastructure)

Filling steel Hollow Structural Section (HSS) columns with concrete achieves increased compression capacity through steel and concrete composite action. Additional benefits to concrete-filled HSS columns include increased fire endurance (research has shown up to 3 hours depending on the level of loading), reduction in the requirements for costly coatings for fire protection, and even increases in connection capacity in some configurations.

While engineers may be aware of these benefits, often questions arise about the practical aspects. Which type of concrete should be specified? What are the limitations? How are connections affected? This article provides guidance on the benefits of concrete-filled HSS with a primary focus on beam-column design. The 2016 Specification is used for this discussion and is referred to as AISC 360-16.

Hydraulic Performance Benefits of Engineered Earth Anchors (Print PDH from the February 2021 issue of Informed Infrastructure)

Rapid growth in the construction industry, the removal of natural vegetation and an increased demand on our waterways has caused the problem of erosion to become a major yet often-overlooked issue in the world. The removal of natural vegetation during construction along with increased conveyance has caused erosion rates to rapidly increase.

Therefore, engineered solutions to mitigate soil erosion have become more critical to the overall success of infrastructure. A practical and cost-effective solution to the problem of erosion is to use a High Performance Turf Reinforcement Mat (HPTRM). HPTRMs are geosynthetic materials that reduce erosion by retaining and protecting the soil below when in an unvegetated state as well as reinforcing vegetation as it establishes, greatly increasing the hydraulic limits of natural vegetation.

Many bridge owners today are burdened with narrow design windows, ever-shrinking design and construction budgets, and tight construction timelines. To serve these situations, we, as bridge engineers, often need to put away the finite-element model and instead rely on a classic, tried-and-true engineering design principle: KISS (keep it simple, stupid). Prefabricated modular steel bridges are founded on this principle by using simple materials, simple geometries, simple analysis models, simple erection equipment and simple installation techniques. However, even the simplest bridge designs require comprehensive engineering evaluation and analysis to maximize the structure’s performance at a minimal cost.

The False Equivalency When Using Pipe Stiffness to Compare Flexible Sewer Pipe (Print PDH from the October 2020 issue of Informed Infrastructure)

This PDH has expired

Buried flexible sewer pipes come in a variety of materials. The most common in the United States are corrugated metal (CMP), polyvinyl chloride (PVC), centrifugally cast glass-fiber-reinforced polymer mortar (CCFRPM or fiberglass), solid wall polyethylene (PE), steel reinforced polyethylene (SRPE), corrugated PE and polypropylene (PP) pipe. Design engineers often seek simple ways to compare between all of these different materials. It is easy to categorize the various materials by use of simple acronyms such as CMP, HDPE, PVC, etc.

For hydraulics, the Manning’s (n) value is utilized. For joint tightness, referencing the requirements of ASTM D3212’s 10.8 psi water tightness is the most common. In pressure applications, there are pressure ratings. It is more difficult, however, to find a simplistic way to quantitatively compare structural performance or pipe strength. One of the most common ways to attempt to compare structural performance is the use of pipe stiffness.

Designing Manufactured Treatment Devices (MTDs) with Maintenance in Mind (Print PDH from the August 2020 issue of Informed Infrastructure)

This PDH has expired

Manufactured Treatment Devices (MTDs) are similar to non-proprietary stormwater BMPs in that they must be maintained so they perform as intended. However, the majority of effort and focus is placed upon the initial design and construction of stormwater treatment facilities, with little thought as to how these systems will be maintained long-term. The property owner, in all cases, is left responsible for the consequences of decisions made by others during the design and construction phases, nearly all of whom have moved on to new projects after the construction phase of the project is terminated.

This is changing, as civil engineers are now placing more importance on the long-term maintenance costs associated with MTDs. To serve the best interest of their clients, not only does the specifying engineer have the responsibility to select and design the stormwater BMP that meets the site’s structural and regulatory requirements, they also have a responsibility to consider long-term cost of ownership as well as initial capital costs.

Prepackaged Pump Stations Provide Optimal Solutions for Wastewater, Stormwater and Industrial Applications (Print PDH from the June 2020 issue of Informed Infrastructure)

This PDH has expired

Pump stations (also known as lift stations) are an important and ever-growing part of the U.S. infrastructure. All drainage, whether wastewater, stormwater or industrial, takes advantage of gravity for the longest distance feasible by the given topography. In most cases, the gravity opportunity runs out before the required destination. At this point, the media needs to be collected and lifted via pumps and a force main to its final destination or to a new location where gravity can again take over. The number of pump stations is increasing across the country because of a reduction of septic systems, expanding mandates to manage stormwater, and an increasing need to develop in flat, low-lying areas.

When left uncontrolled, water has created the deepest of canyons and destroyed countless properties. Sediment transport in streams and rivers is inevitable, but erosion must be controlled in critical areas for safety and economic reasons. Stream restoration and stabilization may require the use of armoring countermeasures to provide lateral or vertical stability to a stream. Articulated concrete block (ACB) revetment systems provide permanent erosion protection against the hydraulic forces of moving water. They are used when vegetation, soil remediation or other forms of hard armoring are unstable or unsuitable for a given hydraulic event or where the consequence of failure is not acceptable.

Precast Structural Alternatives for a Green Solution (Print PDH from the June 2019 issue of Informed Infrastructure)

This PDH has expired

Concrete plays an integral role in urban development, from the fabrication of underground sewer lines to the construction of bridges and interstate highways. However, this development increases impervious surfaces that, in turn, generate more stormwater runoff, which often carries pollutants produced by the activities that occur on the impervious surfaces. These pollutants can include trash and debris, sediment, nutrients, dissolved metals, and petroleum hydrocarbons. Increased stormwater runoff also can erode and degrade the urban streams that ultimately receive the flow and may cause flooding issues for existing development downstream. The quality and quantity of stormwater runoff can threaten wildlife, natural systems and aesthetics. Fortunately, concrete also is part of the solution to these problems.

Introduction to CJ Series Steel Joists in Floor Systems (Print PDH from the June 2019 issue of Informed Infrastructure)

This PDH has expired

Composite and noncomposite steel joists are utilized to support concrete floor systems. This article highlights the use of Steel Joist Institute (SJI) CJ-Series composite joists. SJI CJ-Series composite steel joists utilize shear studs welded through the steel deck to the underlying top chord angles of the steel joists (see Figures 1 and 2). Steel joist top chords typically are fabricated utilizing hot-rolled or cold-formed steel angles. A typical 1-inch horizontal gap between the top chord angles requires that the shear studs be welded to the top chord horizontal legs on either side of this gap.

After the concrete is placed on the steel deck and allowed to cure, the concrete slab acts as a compression chord element for the steel joist. Installed welded shear studs transfer the horizontal shear between the concrete slab and steel joist.

Practical Design Considerations That Can Extend The Service Life Of Metal Buried Bridge And Culvert Structures (Print PDH from the April 2019 issue of Informed Infrastructure)

This PDH has expired

Buried bridges can be described as a buried structure with a clear span of 20 feet or greater that supports an embankment and engages the passive support of the backfill material surrounding it. There are many different types of buried bridges used in highway construction. Some solutions are constructed from concrete; others utilize steel or aluminum in their designs. Buried culvert pipes utilize the same passive soil support and share many similar issues that impact the service lives of these structures.

Buried structures frequently offer advantages over traditional slab bridges. Pavement design and maintenance are simplified with buried structures, as the same pavement design used in the roadway profile can typically be utilized over the buried structures. Buried pipes and bridges often provide accelerated design and construction schedules as compared to conventional bridges. Because buried structures help dissipate surface live loads, they frequently can utilize full inverts or shallow foundations and eliminate the need for piling or other deep foundations commonly used in conventional bridge construction. All of these advantages often lead to lower installed costs as well.

Design Considerations for Wildlife Crossings (Print PDH from the Nov/Dec 2018 issue of Informed Infrastructure)

This PDH has expired

The term “wildlife crossing” describes a variety of structures that are designed or retrofitted to provide safe passage for wildlife above or below a highway. Although wildlife crossing structures are not standardized designs, they can be categorized as two major types: overpasses and underpasses. Structures often are built in combination with fencing to increase their effectiveness.

Each crossing is designed to serve the target species for a specific location or accommodate the majority of species in an area. When wildlife crossing structures are designed for motorist safety, the target species typically are large ungulates such as moose, elk or deer. Other wildlife crossings are designed for species with high conservation concern, such as salamanders, desert tortoises, flying squirrels or kit foxes.

Designing, Modeling, & Labeling ADA Compliant Ramps With Civil Cells (Print PDH from the September/October 2018 issue of Informed Infrastructure)

This PDH has expired

Designing ADA-compliant wheelchair ramps for installation in new or rehabilitated roadway intersections is a common task for civil engineers and other designers. Common, but not routine; adapting the ADA guidelines to particular situations can be tedious, and it’s very possible to make mistakes that lead to change orders and rework. In fact, non-compliant ramps are so common that redesigning ramps for reconstruction also is a common task for designers.

Seismic Behavior of Helical Piles in Dense Sands( Archived Webcast)

Originally Aired July 19, 2018. This webcast has expired

Helical piles are being used in seismic regions of the U.S. and other countries, yet there remains much confusion regarding the state of practice and building codes for this pile type. Nonetheless, it is anticipated that piles with comparatively small cross-sections and high anchoring capacity, such as helical piles, could be beneficial for seismic resistance due to their slenderness, higher damping ratios, ductility, and resistance to tip uplift. Results from the premier full-scale seismic shake table testing program on helical piles in sands will be discussed.

How to Design a Culvert Reline Project (Print PDH from the May/June 2018 issue of Informed Infrastructure)

This PDH has expired

Culvert replacements are a common reality for all owners of drainage infrastructure and a routine part of maintenance and expansion projects on federal lands, roadways and railroads; state department of transportation (DOT) roadways; and at the local level with county, township and municipality owned transportation corridors. Fortunately, culvert rehabilitation via relining has gained momentum as a viable alternative to culvert replacement when dealing with aging drainage infrastructure. Whether an owner of a culvert wants to take a traditional design and delivery approach or conduct the work themselves, the construction methods of many reline options can be performed by parties whose normal work activities don’t include reline construction. In addition, most methods can be performed by in-house maintenance teams or entities who do more traditional open cut drainage work.

Designing Dam Embankments with Articulating Concrete Block Systems (Print PDH from the January/February 2017 issue of Informed Infrastructure)

This PDH has expired

Dams are called “installations containing dangerous forces” in International Humanitarian Law; there is potential for great destruction to people, property and the environment in the event of a dam failure. The forces that make dams dangerous also provide essential benefits such as drinking water, flood control, power production, irrigation and recreation. Holding a balance between destructive forces and essential benefits lies, to some degree, in protecting the dam from soil erosion when an overtopping event occurs.
