Which Concrete Forms are Used in Highway Construction?

Since the 1950s, the popularity of formwork in highway construction has been on the rise. It’s useful for paving long stretches of highway as well as building structures for elevated sections of highway systems. There are numerous uses of formwork in highway construction, and timber, steel, aluminum, and plastic forms are all common in highway projects. Various styles of formwork are well-suited to the creation of highways. Below are five different concrete forms used in highway construction:

1. Column Formwork

This type of formwork is used to create concrete columns to support elevated highways. It’s an excellent choice for urban highway projects that necessitate highway structures above ground. Column formwork, also sometimes referred to as pier formwork, comes in both spherical and rectangular designs (among other types of designs) to suit the various structural and aesthetic needs of highway projects.

2. Deck Formwork

For elevated areas of highway that require the creation of deck structures, deck formwork is often of great use. Deck formwork used to create highway structures is similar to the deck formwork used to create bridge structures. It’s a category of beam formwork. For long spans of elevated highway decks, deck formwork is frequently cast one module or section at a time. The end result is a long, continuous superstructure of connected modules.

3. Beam Formwork

Anytime beams are needed in highway construction, beam formwork is a go-to option. Beam formwork typically comes in the shape of a three-sided box and can be applied in a variety of ways to create structures for elevated highways as well as other highway-related concrete shapes.When creating elevated highways, column formwork is frequently cast to the underside of concrete structures created with beam formwork. After which, it’s common for a collar of formwork to be clamped around column structures to support additional concrete beams as they are cast.

4. Plate Girder Formwork

Plate girder formwork is used to create girder bridge structures that belong to highway systems that involve elevated sections of highway. Plate girder formwork has the ability to create heavy-duty wall sections to support elevated girder bridges.These are just some of the most popular styles of formwork used in highway construction. Most of the styles of formwork listed above are used temporarily. Once concrete is cast, forms are removed and can be used for other highway projects or be used for bridge projects with similar needs. There’s quite a bit of overlap between the styles of formwork used for highway construction and bridge construction. When purchasing formwork for highway construction, factors such as the necessary dimensions and load bearing capabilities of finished concrete products should be taken into consideration.

What are Common Mistakes in Concrete Forming?

The use of concrete formwork is a fairly delicate process. When done well, concrete forming results in structurally reliable and attractive concrete structures. When done improperly, a lot can go wrong. Formwork fails are not uncommon, and most of them can be prevented by avoiding these ten frequent mistakes in concrete:1. You’re using the wrong design. This is a big mistake that can cause serious issues. Formwork must be properly designed for the job. Its design must be strong enough to support concrete during pours and vibration and to produce the desired concrete shape. Keep in mind that sometimes the load bearing capacity of forms can decrease over time after several uses. Formwork should be carefully inspected before it is used to ensure its capabilities have not changed.2. Forms are assembled or erected incorrectly. If formwork is assembled on-site, it should be done so according to pre-established specifications and protocol for the project. Pre-engineered forms should be thoroughly inspected to make sure they are assembled according to the recommendations of their manufacturer. Proper installation of formwork according to manufacturer recommendations as well as project requirements is also critical.3. Components are damaged or defective. Form components should be damage and corrosion free before formwork is used, particularly if using them will result in insufficient connections. If they are not in the best shape, they should be swapped out with different components.4. Forms are removed too early. Concrete must properly cure prior to the removal of forms. If they are removed too early, there is a significant risk that the structural integrity of the concrete will be negatively affected.5. The foundation is weak. If a formwork foundation is weak, it may not be able to transfer the load to the ground. This may be the case if a foundation is on weak subsoil or if concrete pads or piles are not strong and supportive enough. A weak foundation may result in a collapse of formwork.6. Shoring is done improperly. If this happens, impact loads from factors like concrete debris may result in a collapse of vertical shores during a concrete pour. Shoring should be done in a way that creates a continuous load path from forms to their foundation.7. Formwork isn’t inspected before use. Formwork should be inspected before it’s assembled, after it’s assembled, after it’s installed, and right before a concrete pour begins to prevent any issues.8. Forms aren’t properly oiled before and after use. A release agent should be applied to formwork before a concrete pour begins and after the concrete cures and the formwork is removed. Neglecting to use a release agent can damage formwork and negatively impact its ability to safely and effectively perform its job.9. Formwork isn’t adequately monitored during a concrete pour. The unexpected can happen during a pour. And no matter how well formwork is inspected beforehand, something may still go wrong. It’s very important to keep a close eye on forms while they are being filled with concrete.10. Formwork is overloaded during concrete pouring. This is another reason to closely monitor forms during a pour. If formwork is overloaded, a collapse is a definite possibility and could cause serious issues.Get the most out of your formwork by avoiding the mistakes above, and be sure to take good care of your forms with proper, regular maintenance!

Which Types of Concrete Forms are Used in Bridge Construction?

Concrete formwork is incredibly useful in bridge construction, and it helps ensure that bridges are constructed with precision in order to be both visually appealing and structurally efficient. There are a number of different bridge components that can be constructed using various types of concrete formwork, whether pre-engineered steel or aluminum forms or timber forms. Below are seven different types of concrete forms that are common in the construction of bridges as well as overpasses:

1. Bridge Deck Formwork

This is formwork used to cast horizontal concrete structures to create bridge decks. It’s a type of beam formwork. For longer bridges, bridge deck formwork is often cast one section at a time, ultimately resulting in a continuous superstructure of connected sections that achieve the necessary bridge deck size and load bearing capabilities.

2. Bridge Overhang Formwork Systems

These forms are used to create bridge overhangs. Bridge overhang brackets are installed, and then formwork is secured to them in order to cast structures that serve as overhang areas.

3. Composite Bridge Forms

These forms are intended for use with composite bridges as well as concrete bridges that have been partially pre-cast. They are a type of cantilever formwork, which means that bridge sections are cast one at a time using a set of cantilever traveling forms that are employed outward from the head of a pier, carrying the forms, rebar, and load of fresh concrete in each cycle.

4. Parapet Formwork

This is a type of cantilever formwork used to create concrete parapet structures. Cantilevered parapets serve as a boundary along the two sides of a bridge structure. They protect bridge sealings and enhance the visual aesthetics of lateral barriers.

5. Truss Formwork Systems

These systems are modular trusses, which are comprised of beams to create rigid structures of desired shapes and sizes. They are great for creating big spans of concrete in cycles. They minimize the amount of ground shorings required, are easy to install, and are ideal for civil engineering projects.

6. Pylon Formwork

Able to create vertical concrete structures that support bridge decks and overpasses, pylon formwork ensures that the structures that are cast are sturdy and strong enough to support significant loads. Pylon formwork may self-climbing, which means it can climb upward to the next module of a cycle and build upon itself.

7. Heavy Duty Bracket Forms

Great for pier cap or pier head casting, these types of forms are another cantilever type with high load bearing capacities and relatively simple designs that make them convenient and easy to use.

OVERALL

These are some but not all of the common types of forms used to construct bridges and similar structures. Some forms may be designed specifically to meet the needs of a particular project. Most of the types of formwork listed above can be re-used for future projects or sold if no longer needed. Pre-engineered bridge construction formwork generally retains its value exceptionally well and lasts a fairly long time before needing to be replaced. Occasionally, some types of bridge construction formwork may be permanent and remain part of a final bridge structure, but most types are temporary.

Why Buy Used Steel Beams?

Used steel beams, also called surplus steel beams, are beams that have been used before and are sold for reuse. Due to the increasing prices of steel, the sky-high cost of mills, and the time it takes for new beams to be manufactured, purchasing used steel beams can be a smart, cost-effective option depending on your project needs.

Where Do Used Steel Beams Come From?

Used steel beam includes any beam that does not come directly from the manufacturer, but rather from a job site or other location where it’s been used before. Though this often means that the beam has light wear and tear, in some cases, used beam can be unused and deemed as “surplus”. This happens in instances where the beam was left over from another project, where more beam was ordered than needed, or where scraps of beam were left over from being cut.

Pros of Purchasing Used Steel Beam

There are many advantages to purchasing used steel beam options over new steel beams.First, the price of used steel beam can be lower than the price of new steel beam, even for exactly the same product. Despite an unpredictable year, steel prices have continued to rise through the first quarter of 2021. A decreased steel supply mixed with rising demand account for this change. Steel prices in 2021 are expected to remain high, which is why many builders are looking for alternate, affordable options, including purchasing used steel beam over new steel beam.In addition to cost benefits, purchasing used steel beams can cut down the time of a project, since used steel beam is already manufactured and ready to use, and does not come with the potential for delays or backlogs. In many cases, pre-manufactured used steel beam is just as effective as new steel beam and can be used successfully in its place.

Common Sizes for Steel Beam

Steel beam comes in a wide range of sizes, including both wide flange piles and H-piles. Some common sizes include:
  • W8: W8x18, W8x21, W8x24, W8x28, W8x31, W8x35, W8x40, W8x48, W8x58, W8x67

How to Inspect Concrete Formwork

Concrete formwork should always be properly inspected before use. This is the case whether you’ve utilized the formwork for previous projects or whether you have recently bought it used or new from a seller. It’s a good idea to routinely inspect it if it’s in storage and you plan to re-use it, especially if it’s been in storage for any significant period of time. Using concrete forms that have not been well-maintained and that are damaged in any way can compromise the success and safety of a project. Inspecting concrete formwork is a relatively simple process. Below are some suggestions for thorough and proper inspection:

1. Look for excessive rust and corrosion.

Pre-engineered steel and aluminum forms are generally pretty tough against rust and corrosion, but you should still keep an eye out for any excessive rust and corrosion that may compromise the quality of the formwork. Excessive rust can, among other things, lead to rust stains on concrete structures during the forming process. As a part of your maintenance of your formwork, you should do the most you can to help prevent rust and corrosion by storing forms in protected, covered locations.

2. Check for warping or bent forms.

Warping or any bent areas are major red flags that need to be addressed before formwork is used. If using timber formwork, make sure the wood is not chipped, tearing, or rotting in any areas. Warped, bent, or otherwise damaged sections of formwork should be repaired or replaced to ensure the integrity of future concrete structures.

3. Keep an eye out for concrete residue.

Concrete residue should be cleaned off after each use of formwork. That being said, sometimes it’s easy to miss a little bit of residue. Before formwork is used again, it’s a great idea to inspect it for any leftover residue. Any and all residue should be adequately removed before formwork is installed and before cement is poured.

4. Inspect for wear and tear and other damage from prolonged storage.

Ideally, when formwork isn’t in use, it should be stored in a covered area so it’s protected from the elements. If, for some reason, it’s not stored in a covered area, make sure you inspect it for weather-related damage on a regular basis and consider storing it in a more protected area if it’s out of use for long periods of time (if possible). Even if it is housed in a covered or enclosed area, it’s a good idea to check on it in storage on a routine basis to make sure it hasn’t picked up any new damage or wear and tear.

5. Assess whether it needs some extra oiling up.

Release agents should be used on formwork before and after each use. If it’s out of use for a while, a part of your routine inspection should be to assess whether more release agent should be applied if needed. This may be the case if it has been in storage for a long period of time.Inspection of concrete formwork will differ on a case-by-case basis depending upon the type of formwork involved, but the recommendations above are useful for most types of forms. Routine inspection can be an invaluable part of your maintenance of formwork and can ultimately extend its longevity, allowing you to get the most value out of your concrete formwork in the long run.

Eiffel 101: Small Steel H-Pile Applications

H-piles are one of several different types of piling. They’re as wide as they are deep and have the same thickness in the flange and web. When compared to standard beams, H-pile beams provides better weight distribution over a wider area. Although they can be designed for skin friction, the H-pile shape is most effective at transferring loads through the pile to the end. Small H-piles have a wide range of applications, including for falsework, soldier piles, residential projects, industrial facilities, walers, templates, and more.

Small Steel H-Pile for Falsework

Falsework is a temporary structure made of steel piles that’s used to support a separate, permanent structure while it’s under construction. Falsework includes the piles, foundation, footing and all other structural elements that support a permanent structure while it’s being built. Falsework is often made from small steel H-piles and fittings that are combined with adjustable telescopic props and flat heads, which support timber bearers. It is on these timber bearers where the formwork (or deck) is built. Secondary beams may also be inserted between the main bearers and the formwork.

Small Steel H-Pile for Soldier Piles

Soldier piles are a type of earth retention system commonly used in the foundation building process. They are also used for slope stabilization and remediation. The piles are commonly made of small steel H-pile that’s driven into the ground to help distribute the weight of the structure from the loose topsoil down to the rock below. Soldier piles can also be used to create retaining wall systems for temporary projects, such as excavation during the construction phases.

Small Steel H-Pile for Residential Projects

Small steel H-pile is commonly used in projects for a variety of residential buildings, including condominiums, townhomes, single family homes, and apartment buildings. They also have applications in the construction or repair of other structures, such as garages, retaining walls, parking lots, swimming pools, lots, and landscaped areas.

Small Steel H-Pile for Industrial Facilities

Small steel H-pile is versatile, which makes it a common foundational building material in a wide range of industrial facilities, including warehouses, distribution buildings, manufacturing buildings, large refrigeration buildings, telecom or data hosting centers, research and development buildings, and showrooms.

Small Steel H-Pile for Walers

Wales are horizontal beams that are bolted to a larger upright structure, such as a dock, in order to help support it. They can be placed at different heights or angles along a structure in order to bolster it most efficiently. Walers are commonly made using small steel H-pile.

Common Sizes for Small Steel H-Pile

Small steel H-pile comes in a variety of standard sizes, which include the following:
  • HP8: HP8x36
  • HP10: HP10x42, HP10x57
  • HP12: HP12x53, HP12x63, HP12x74, HP12x84, HP12x89, HP12x102, HP12x117
  • HP14: HP14x73, HP14x89, HP14x102, HP14x117

Eiffel 101: Large Steel H-Pile Applications

Large H-piles are a type of steel pile that are as wide as they are deep, with the same thickness in the flange and web. Because of their design, large steel H-piles provide a better weight distribution over a wider area and can support larger and heavier structures; individual large piles have been tested to withstand loads of 1,000 tons. Due to their high loadbearing capacity, large H-piles have foundational applications in factories, airports, stadiums, bridges, skyscrapers, and more.

Large Steel H-Pile Factory Applications

Large steel H-pile has a high loadbearing capacity, which makes it a common foundational building material in a wide range of large industrial facilities, including warehouses, plastic manufacturing plants, nuclear power plants, oil refineries, chemical plants, fertilizer plants, metal manufacturing plants, food production plants, clothing manufacturers, transportation manufacturers, wood and paper manufacturers, and more.

Large Steel H-Pile Airport Applications

Large steel H-pile is often used as part of the foundation for heavy structures like airports. The steel piles are driven or drilled into the ground in order to help distribute the weight of the airport from the loose topsoil down to the stronger soil or rock below. Without the use of large steel h-pile, it would be difficult to achieve the stability needed to support airports.

Large Steel H-Pile Stadium Applications

Though stadiums originated in ancient Greece, the first modern facilities were constructed in the mid-19th century. The construction of a sports stadium can take up to three years, and typically begins with a site excavation to create the seating bowl, which can be over 50 feet beneath the ground. This is followed by masonry work and the manufacturing and installation of precast components that serve as the foundation for the new stadium. Large steel H-pile commonly comes into play during this phase of construction, as it is utilized in the construction of stadium foundations.

Large Steel H-Pile Bridge Applications

Because bridges must be able to hold not only its own weight, but all of the weight of the traffic traversing the bridge, it’s essential that it is built on a strong foundation. Bridge foundations are constructed by sinking caissons into the riverbed and filling them with concrete. Caissons are large boxes or cylinders that have been made from a variety of materials, including large steel H-pile.

Large Steel H-Pile Skyscraper Applications

Skyscrapers including high rise buildings with over 40 or 50 floors, though the tallest skyscrapers can have over 100 floors. There was a time when it wasn’t possible to continue increasing the width and strength of concrete foundations, which is why mass produced steel and iron has been essential to creating taller buildings. Large steel H-pile is a lightweight material given its loadbearing capacity, and is essential to the construction of skyscrapers.

Common Large Steel H-Pile Sizes

Traditionally, H-pile was made in 8-, 10-, 12-, and 14-inch sizes. In recent years, those sizes have nearly doubled through the addition of 16- and 18-inch pile. Listed below are common sizes of larger-flange h-pile beams:
  • HP12: HP12x53, HP12x63, HP12x74, HP12x84, HP12x89, HP12x102, HP12x117
  • HP14: HP14x73, HP14x89, HP14x102, HP14x117
  • HP16: HP16x88, HP16x101, HP16x121, HP16x141, HP16x162, HP16x183

What is Bracing?

If problems arise with a building’s foundation, it can cause costly damage, create safety hazards, and reduce the value of the structure. Wall bracing is used to help secure a structure in order to prevent foundational issues.Similarly, trench shoring, which is a kind of bracing, is used to brace the walls of a trench to prevent collapse and cave-ins, and braced cofferdams involve a bracing system to support the walls of an excavation project.In each of these scenarios, bracing helps stabilize structures to prevent buckling or collapse.

How Does Wall Bracing Work?

Wall bracing involves the use of steel braces, often made of steel pile beams, to help a structure support its own weight, as well as to “brace” against outside forces such as wind, earthquakes, water leaks, and more. Wall braces are one of the most effective ways to repair and restore buildings and to protect against foundational shifts or damage.Bracing can protect against:WaterWater leaks and excessive moisture can cause mold and mildew to grow within a structure. Similarly, when it’s cold outside, water or moisture trapped in cracks can freeze and expand, which can cause the cracks to stretch or break. By installing a steel brace to hold the foundation in place, these structural issues can be prevented.Buckling WallsWalls can buckle due to moisture, the weight of the structure, or old age. Steel wall reinforcement braces provide support for older foundations that may be buckling inward due to the weight of exterior soil and water.CollapseOver time, building foundation can become damaged and develop cracks, which can eventually collapse. If wall braces are in place, they can prevent structural collapse.

How Does Trench Shoring Work?

One of the most common methods used for trench shoring is called “beam and plate,” in which steel I-beams are driven into the ground and steel plates are slid in among them. (A similar method that uses wood planks is called soldier boarding). Though hydraulic methods can be faster and easier, the beam and plate method can be used for longer term applications or larger excavations.

How Do Braced Cofferdams Work?

Braced cofferdams are systems used in urban areas to support the walls of an excavation project, or to prevent water from entering an excavation. Braced cofferdams are comprised of a sheeting and bracing system and are frequently used in the construction of bridge piers and abutments. The cofferdams can be made with soldier beams that are driven into the earth prior to the start of excavation. Laggings are placed between the soldier beams as the excavation begins. As soon as the excavation reaches the level of each tier, wales and struts are installed. The soldier beams are sometimes left in place and used as support of the permanent wall.

Steel Beam Application: Retaining Walls

A retaining wall is a structure that holds (or “retains”) the soil behind it. Though there are many types of materials that can be used to create retaining walls (including concrete blocks, poured concrete, treated timbers, rocks and boulders), the strongest retaining walls are often created using steel beams and/or steel sheet pile.

Gravity Walls vs. Reinforced Walls

Gravity retaining walls are walls that use their own weight to retain the soil. Gravity retaining walls are typically shorter in height and work by locking together into place to create the setback. This setback helps the wall support the pressure from the soils behind it.On the other hand, reinforced retaining walls use some type of reinforcement, such as steel beams, to give the wall more strength.

Comparing Materials Used to Create Retaining Walls

Wood

Wood is often chosen for retaining walls because its inexpensive. However, the short lifespan of wood makes it a poor choice when compared to other options. As the wood decomposes, the retaining wall will begin to crumble as well, harming the integrity of the usable space.

Stones, Rocks and Boulders

Stones, rocks or boulders can create some of the most appealing retaining walls that will last over time. However, these materials can be expensive and labor intensive.

Cast-In-Place or Mortared Retaining Walls

Both cast-in-place and mortared retaining walls use a mix of veneers, bricks and flagstones, which add texture and style. However, these structures are rigid and do not move and flex as the soil around them changes, meaning they are more likely to crack over time.

Steel Beams

Steel is used in the creation of soldier pile retaining walls, soil nailing retaining walls and gabion walls. Steel is more expensive than timber, but it’s easy to work with, customizable, reliable and long lasting. Steel beam retaining walls are some of the strongest.

Types of Steel Beam Retaining Walls

Soldier Pile Walls

Soldier pile walls are commonly installed at property lines and to stabilize landslides. They are made using vertical steel beams, which are embedded into holes drilled into the soil. The holes are filled with a concrete grout mix so that the steel beams can cantilever to resist soil pressure. The steel beams are typically spaced at eight feet on center with wood lagging between the beams to support the soil.

Soil Nailing

Soil nailing is commonly used in areas with tight access, or in areas that require a top-down construction method. Soil nailing is done by drilling holes and inserting long steel beams that are pressure grouted into the hillside. The face of the hillside is then sprayed with concrete grout to hold the structure in place.

Gabion Walls

Gabion walls are gravity walls that utilize wired steel baskets, which are filled with quarry spalls (rocks).

Common Sizes for Retaining Wall Steel Beams

Steel beams used for retaining walls come in a wide range of large sizes, including both wide flange piles and H-piles. Some common sizes include:Wide flange beams

New Steel Beams vs. Used Steel Beams

Used steel beam is beam that was used in a prior project but has since been uninstalled and resold. While many builders automatically choose new steel beam, used steel beam is a viable, cost-effective option in many scenarios.

Where Do New and Used Steel Beams Come From?

New or “prime” steel beam comes directly from the manufacturer. Steel beam is one of the most commonly used products in the steel industry, and each year millions of tons of steel beam are manufactured and sold around the world.Used (or surplus) steel beam does not come directly from the manufacturer, but rather from a job site or other location where it’s been previously used. Though this sometimes means the steel is old, dirty or corroded, surplus steel beam can also be brand new. In some cases, new steel beam might be sold as “used” or “surplus” if the beam was left over from another project, such as in instances where more beam was ordered than needed, or where scraps of beam were left over from being cut. Furthermore, the quality of used steel beams can also be like-new if the quality has been maintained over time, or they have only been driven a few times.

Pros and Cons of Purchasing New Steel Beams

Some of the pros to purchasing new steel beam include:
  1. New steel beam has never been used before, meaning the structural integrity is known to be solid, and there will be no wear and tear setbacks once construction begins.
  2. New steel beam can be custom rolled and manufactured to a project’s exact specifications.
  3. New steel beam comes with certifications.
The cons of purchasing new steel beam include:
  1. New steel beam costs more than used beam.
  2. If purchasing from a manufacturer, it may take longer for the steel to be produced, and backlogs can occur.

Pros and Cons of Purchasing Used Steel Beams

Some of the pros to purchasing used steel beam include:
  1. The price of used steel beam is lower than new, even for exactly the same product.
  2. Used steel beam is ready for immediate use, since it does not need to be manufactured.
  3. Used steel sometimes comes with mill certifications.
Some of the cons of purchasing used steel beam include:
  1. Used steel beam has been used before, meaning it likely contains some wear and tear.
  2. Used steel beam cannot be custom made to fit an exact project’s needs.
  3. Used steel beam is not guaranteed to come with certifications, though some testing is available
In many cases, surplus steel beam is just as effective as new steel beam and can be used successfully in its place. Surplus steel should always be tested for pressure resistance and durability before use, and beam that doesn’t pass the test should only be used in light-duty situations.

Common Sizes for Steel Beam

Steel beam comes in a wide range of sizes, including both wide flange piles and H-piles. Some common sizes include:
