Steel is one of the most common types of building materials used around the world and can be found in a wide variety of bridges and bridge foundations, including long-span bridges, highway bridges, railroad bridges and footbridges. Approximately one-third of all bridges in the U.S. are built using steel beams.

Steel Beam Applications in Bridge Construction

Steel beam can be used for things like bridge beams, channels, railings, beams, ladders and angled components. Most commonly, however, steel is used to create the bearing pile foundation for a bridge.Bearing piles are a type of deep foundation system installed under the earth to support vertical loads by transferring the bridge’s weight to the soil or rock below. Without such foundations systems, the land beneath the bridge would be unstable and therefore unable to handle significant weight, such as that from traffic, or even the mass of the bridge alone.

Advantages of Steel Beam in Bridge Construction

Steel bearing piles (beams) have many advantages when compared to other types of pile.

1. They’re easy to connect to the bridge.
2. Loads can be set immediately after the pile is installed.
3. Steel is highly-durable and long lasting.
4. There’s no limit to pile length.
5. Steel beams are comparatively easy to install.

Bridge builders choose steel beam over other construction materials like wood or concrete because it’s versatile, cost effective, sustainable, durable, and lasts for decades. Bridge infrastructure made of steel beam is generally stronger, safer, easier to build, and more flexible, which helps prevent against damage from high winds and earthquakes. Similarly, steel beam is more sustainable than other materials, which makes it an environmentally friendly option.

Wide Flange and H-Pile Beams

H-piles and wide flange beams 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 and wide flange beams provides better weight distribution over a wider area. Because of this, they can support larger and heavier bridges.

Common Sizes for Steel Beam in Bridge Construction

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

Buying concrete formwork used as opposed to new can help you cut costs. Since engineered concrete forms can be used around 2,000 or more cycles before being scrapped, buying used is also a sustainable, eco-friendly choice in comparison to buying new. The amount of used forms on the market is growing, offering buyers numerous options to choose from to suit the needs of their individual applications. To get the most value from buying formwork used, there are a few things you should look for to help you rule out forms that may be out of shape or inadequate for your project. Below are some tips to help you find the right used forms:

• Gauge how well forms have been maintained. If you aren’t able to inspect the forms in person before you buy, make sure you’re able to look at pictures of them. If they’re steel or aluminum, look for any signs of concrete residue, and be sure to ask the seller how they’ve been maintained and when release agents were last applied to them. If you’re buying plywood formwork, make sure the wood appears to be in good condition and has been oiled since the forms were last used.
• Check for rusting, warping, and other damage. If formwork is damaged in a way that may compromise its ability to help you create the necessary concrete structures, it’s probably not worth the risk of investing in it, even if the price is right.

• Do a background check on when and how they’ve been used. Be aware of the length and frequency of past use. As mentioned, steel and aluminum forms can be used over and over again, but, at some point, they do begin to degrade and should be retired. The more you know about how and how many times forms have been used, the better.
• Consider overall quality and value. If the formwork meets the needs of your project, is in good condition, and comes at a good price, it might be the perfect investment. While you may want to take things like brand name into consideration, keep in mind that top brands don’t always guarantee quality, especially if formwork hasn’t been maintained well.

Don’t be afraid to reach out to sellers and ask questions about the formwork you’re considering buying. The more you know about it, the better. Once you do purchase used formwork, be sure to properly inspect it in person before you use it. And don’t neglect to follow manufacturer’s recommendations for use as well as apply a release agent to make sure it’s oiled up and ready to go when the cement arrives to your project site.In addition to buying used formwork, you may end up deciding to sell it once you’ve finished using it. Make sure you maintain it well, and you should be able to recoup a good portion of what you paid for it if you do decide to sell. Engineered formwork, in particular, retains its value exceptionally well. Overall, buying and selling used formwork is a sustainable and pocket-friendly choice.

It’s very important for concrete formwork to be installed and removed properly to avoid safety issues to workers and issues that may compromise the integrity of the structures you cast. It’s also integral that you use the right kind of formwork with the right specs for the job. There are a number of things workers can do to boost the safety of projects that involve concrete formwork. Below is a concrete formwork safety checklist to aid in the proper and safe use of forms:

1. Be aware of design specs.

You should obtain detailed information and descriptions of any formwork you plan to use. The more you know about the formwork, the better you’ll be able to assess if it’s the best and ultimately the safest choice for the job required.

2. Make sure it’s properly designed for the job.

Getting the right formwork design for the job matters, and it allows you to know you won’t have any structural issues that could cause safety problems. Design considerations should include load capacity during concrete casting and strength to support structural loads. Additionally, you need to make sure the formwork you’re going to use for a project has the ability to accommodate the amount of concrete you’re going to pour, the temperature of the concrete, etc. Factors such as soil conditions should also be considered when assessing the design of forms.

3. Carefully inspect formwork before it’s used.

A bottom-up inspection should be conducted to make sure no areas of the formwork are damaged, warped, or otherwise compromised. Condition of formwork must be properly assessed to guarantee a safe and successful load transfer.

4. Check ladders, scaffolds, ramps, and other accessories.

They should be in good condition and capable of serving their purposes without any issues. If any accessories are damaged, it’s best to replace them before formwork is used.

5. Clear out room for passageways.

While formwork is being used, there should be safe passageways that allow crew members to get to and from where they need to go. These passageways should remain unobstructed and decluttered while formwork is being installed, is being used, and is being uninstalled.

6. Guard any floor openings or peripheral edges.

This will help prevent falls and reduce hazards to crew members.

7. Make sure there’s enough space for workers.

Workers should not be cramped during installation, use, or removal of formwork. They should have ample room to safely perform their jobs.

8. Properly train crew members to use formwork.

This is one of the top things you can do to ensure safety. Employees should be well-trained in how to use the formwork and trained to be aware of any safety hazards associated with the use of particular kinds of formwork. They should also be provided with proper safety gear and be trained to know what type of gear they should wear.

9. Examine rigging inserts.

They should be in good condition as well as installed properly and positioned accurately.

10. Pay special attention to props.

They should be inspected to ensure that they are equipped to support required loads. All defective props should be removed, and all props that you use should be aligned vertically, rested on bearing plates, and situated on hard, supportive structures.

11. Remove formwork carefully.

It should be removed according to pre-established procedures. Construction loads should not be placed on newly cast beams or slabs during removal.Safety protocol may differ on a case-by-case basis depending on the needs of the project and the type of formwork you’re using, but the checklist offers general recommendations that should be useful in the majority of formwork applications.

A secant pile wall is a type of retaining wall used to ensure ground retention prior to excavation. Secant pile walls are created by constructing alternating primary and secondary piles (female and male piles) where the secondary piles partially cut into either side of the primary piles in order to form an uninterrupted, impermeable structure.When obstructions are anticipated, secant walls make a good alternative to diaphragm walls, as they have a more flexible shape and offer relatively compact operation. Similarly, secant walls work well in urban projects with limited space.

How Are Secant Pile Walls Constructed?

Secant pile walls are built with intersecting reinforced concrete piles. The piles are reinforced with steel beams and are constructed by drilling under mud. Primary piles are installed first, with secondary piles constructed in between once the primary piles have gained sufficient strength.There are three main types of secant pile walls, which are:

• ‘Hard/Soft’ which uses a bentonite/cement slurry in the primary piles
• ‘Hard/Firm’ which uses high reinforcement/low strength concrete in the primary piles
• ‘Hard/Hard’ which uses a full strength structural concrete in the primary piles

Piles typically overlap by about three inches. Primary piles are secanted by secondary piles, thus providing a closed structure to act as a barrier in water bearing soils, and to prevent the ingress of soil between the piles.

What are the Advantages of Secant Pile Walls?

The main advantages of secant pile walls are:

1. Minimal vibration
2. Increased construction alignment flexibility to fit complex site boundaries
3. Less noisy or disruptive construction
4. Ability to go through underground obstructions such as steel, concrete, etc.
5. Increased wall stiffness compared to sheet piles
6. Can be installed in difficult ground (cobbles/boulders)
7. No need to install timber lagging
8. Avoids risk of construction induced settlements to neighboring structures

What are the Disadvantages of Secant Pile Walls?

The main disadvantages of secant pile walls are:

1. Hard to achieve verticality tolerances for deep piles
2. Waterproofing is difficult to obtain in secant pile joints
3. More expensive than sheet pile walls

Common Sizes for Steel Beams used for Secant Piles

Secant piles can use a wide range of steel pile sizes, including both wide flange piles and H-piles. Some common sizes include:W8: W8x18, W8x21, W8x24, W8x28, W8x31, W8x35, W8x40, W8x48, W8x58, W8x67W10: W10x22, W10x26, W10x30, W10x33, W10x39, W10x45, W10x49, W10x54, W10x60, W10x68, W10x77, W10x88, W10x100, W10x112W12: W12x26, W12x30, W12x35, W12x40, W12x45, W12x50, W12x53, W12x58 ,W12x65, W12x72, W12x79, W12x87, W12x96, W12x106, W26x120, W12x136, W12x152, W12x170, W12x190, W12x210, W12x230, W12x252W14: W14x22, W14x26, W14x30, W14x34, W14x38, W14x43, W14x48, W14x53, W14x61, W14x68, W14x74, W14x82, W14x90, W14x99, W14x109, W14x120, W14x132, W14x145, W14x159, W14x176, W14x193, W14x211, W14x233, W14x257, W14x283W16: W16x26, W16x31, W16x36, W16x40, W16x45, W16x50, W16x57, W16x67, W16x77, W16x89, W16x100W18: W18x35, W18x40, W18x46, W18x50, W18x55, W18x60, W18x65, W18x71, W18x76, W18x86, W18x97, W18x106, W18x119, W18x130, W18x143, W18x158, W18x175, W18x192, W18x211, W18x234HP8: HP8x36HP10: HP10x42HP12: HP12x53, HP12x63, HP12x74, HP12x84, HP12x89, HP12x102, HP12x117HP14: HP14x73, HP14x89, HP14x102, HP14x117HP16: HP16x88, HP16x101, HP16x121, HP16x141, HP16x162, HP16x183

The faster and more efficiently you finish concrete construction, the better for your project and for your pocketbook. Using pre-engineered concrete formwork as opposed to many other modes of concrete construction already gives you an edge in terms of efficiency. Still, there are mistakes you could make when you use concrete formwork that could slow your project down or even stall it. Efficient use of concrete formwork often involves adequate preparation and preventative measures to prevent issues. Below are 8 tips to help you boost the efficiency of using concrete forms:

1. Ditch Damaged Formwork and Equipment

Before you use any formwork or shoring equipment, you should carefully inspect it for cracks, warping, and any other damage. If forms or equipment are damaged in a way that may compromise the successful use of forms, it’s a good idea to either repair them or replace them. Doing so can ultimately save you a lot of hassle.

2. Get Ready for Concrete to Be Delivered

Formwork should be installed and ready to go, and any equipment should be ready to use. Proper preparation will cut down unnecessary down time. When the concrete arrives on-site, you should be prepared to start pouring immediately.

3. Install Formwork in the Correct Location

This is an essential preparation step and should be done before concrete arrives to a site. Once you actually start pouring concrete, it’s too late to move forms for a re-do until after the concrete sets. If you do install formwork in an incorrect location, correcting the issue after the fact can be time-consuming and costly.

4. Follow Manufacturer’s Guidelines

You should be well-aware of manufacturer’s guidelines for any pre-engineered concrete formwork you use. You want to make sure you use the formwork to its full potential, and you also want to avoid any safety issues that may arise as a result of not using it properly. You should follow all manufacturer’s instructions for any equipment or additional materials you use as well.

5. Make Use of Concrete Vibrators

Concrete vibration allows for stronger, denser concrete. It also enhances product finish and reduces the amount of concrete required. You want to ensure that your final product is durable, and concrete vibrators can help you do so. You don’t want to have to deal with a collapsed wall because you opted to forgo concrete vibration.

6. Brace Formwork Correctly

Correct bracing of formwork is incredibly important. If formwork isn’t adequately braced, bulging and formwork failure is highly possible. Bracing is another preventative measure you should take to ensure that time-consuming and costly issues don’t arise as the project progresses.

7. Remove Forms on Time

Depending on concrete specifications, formwork should be removed approximately two days after pouring. Removing it at the right time allows the concrete to both maintain its shape and for you to finish and round it as necessary easily.

8. Re-Use or Sell Your Forms

Get the most out of your pre-engineered concrete formwork and re-use it for future projects. If you don’t believe you’ll be able to find any applications for it in the foreseeable future, consider selling it. Concrete formwork retains its value quite well, and selling it can be quite profitable.

The short answer to whether or not you should sell your used concrete formwork is yes! There are numerous benefits to doing so and various reasons why you might consider selling your formwork after it’s no longer needed. Below are some things to consider when selling formwork:

1. Condition

If your used formwork is in good condition and you’re not using it anymore, it could be a great idea to sell. Even if it’s in average condition, keep in mind that engineered forms usually last around 2,000 or 3,000 cycles. Even if your forms aren’t shiny and new anymore, that doesn’t mean they aren’t in good working condition. Well-maintained concrete formwork holds its value well, so selling well-maintained formwork is always a great idea. Be aware of obvious damage and warping that may compromise the ability of the forms to do their job, however. You may be able to sell damaged formwork for the price of what the metal’s worth, but don’t expect it to retain its value in the same way once it’s not usable any longer.

2. Value

If it’s still in average or good condition, concrete formwork retains its value quite well. You can’t usually sell it for the same price as it’s sold new, but sometimes you can find a buyer who’s willing to pay a pretty great price if the formwork checks all of the required boxes for their project. How much you can price your formwork for largely depends on the type of formwork it is and the condition it’s in. Do some market research before you set your price. Generally, you can plan to price it around 50% of brand-new value, and fluctuate from there based on condition, storage, availability on the used market, etc.

3. Storage room

If it’s just sitting in a yard or elsewhere in storage and you have no intentions of using it anytime in the near future, why not sell it? It’ll clear up some space for other materials or equipment, and it could offer you some extra cash. Why not let your used formwork generate some extra money for you? Plus, you may be doing a favor for a contractor who’s looking for the exact formwork you’ve had lying around in the yard for years. You can save them a little money and prevent them from having to buy new. It’s a win-win for all!

4. Brand

All brands of concrete formwork retain their value well and can be sold for decent prices, but it may be particularly advantageous for you to sell your used formwork if it’s EFCO or Symons branded. Buyers know and trust these names and are aware of the quality and durability offered by these brands. They’re often willing to pay a higher price due to brand loyalty. If you decide to sell your EFCO or Symons formwork, you can except that it will generate some significant interest from buyers simply because of brand recognition. Have some laying around? Why not sell it!These are some of the most basic and compelling reasons to sell your used formwork. Doing so can also be a sustainable choice. The more used formwork is re-used, the more sustainable it becomes. There’s nothing wrong with holding onto your old formwork, but if you’re not getting anything out of it, selling it can make a whole lot of sense!

Falsework is a temporary structure made of steel piles used to support a separate, permanent structure while it’s under construction. As soon as the permanent structure can support itself, the falsework is removed.Formwork is a type of falsework that’s used to mold concrete during the construction of buildings, bridges and elevated roadways. When falsework is applied to arches, it’s called centering.Falsework includes the piles, foundation, footing and all other structural elements that support a permanent structure while it’s being built. Falsework can be used to support formwork for in-situ concrete, prefabricated concrete elements, steel section, stone arches, etc.

How Is Falsework Constructed?

Falsework is often made from steel 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.If more specialized work is needed, such as when the load being supported is particularly heavy, prefabricated steel frames, military trestles, towers, steel girders, and standard steel sections can be employed.Falsework is erected in a few main steps. First metalworkers fabricate a falsework section from pipes and beams. Next, the section is lifted with the assistance of large machinery, such as forklifts, while a ground crew guides the section into position. Finally, the falsework is secured into place.

Falsework Risks and Considerations

The greatest risk to be considered when working with falsework is the potential for collapse, which can lead to injury for those on the structure, as well as the potential for falling materials, such as if a worker drops a tool while working high on the falsework. Usually, collapses occur when the structure is being loaded and when the concrete is being placed, because this is the time when the number of workers involved is at its highest. Both of these risks can be managed with the right training and safety precautions.

Common Sizes for Falsework Piles

Wide flange beams and h-pile beams can be used as falsework. Here are common sizes:

Braced cofferdams are systems used in urban areas to support the walls of an excavation project, or the 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.

What Are the Components of a Braced Cofferdam?

Braced cofferdams include the following components:

• Laggings – Laggings are horizontal timber planks that are set by hand as the excavation is underway.
• Sheet piling – Sheet pilings are timber, steel or concrete sheet piles that are installed into the earth by vertical pile driving.
• Soldier beams – Soldier beams are vertical beams made of timber or steel that take reaction from laggings. When sheet piles are used, soldier beams are not required.
• Wales – Whales are horizontal beams used to transfer reaction from laggings or sheeting to the struts.
• Struts – Struts are compression member that are used to carry reaction from one side to other side of excavation.

What Are the Types of Braced Cofferdam?

Braced cofferdams come in three main types:1. Braced Cofferdams with Wales and Soldier BeamsBraced cofferdams with wales and soldier beams are best used during small excavation projects since no heavy equipment is required for construction. They can be used for excavations with depths up to 4.5 meters.2. Braced Cofferdams with Wales and Without Sheet PilesBraced cofferdams with wales and without sheet piles are made of soldier beams that are driven into the earth prior to the start of excavation. Laggings are placed between the soldier beams as the excavation is underway. As soon as the excavation reaches the level of each tier, wales and struts are installed.Braced cofferdams with wales and without sheet piles is best used for deep excavation projects. This is because the soldier beams allow for stability of the system and prevent the bottom from heaving. Soldier beams are sometimes left in place and used as support of the permanent wall.3. Braced Cofferdams with Sheet PilesBraced cofferdams with sheet piles are the final type of braced cofferdam. The sheet piles are driven prior to excavation to the proposed depth. As the excavation project continues, wales and struts are installed. The excavation is continued and another set of wales and struts are installed. The benefits of braced cofferdams with sheet piles is that there is no danger of bottom heave; no danger of loss of ground in granular soils; the sheet pilings work well as cutoff wall; the cost of de-watering is reduced; and piping, boiling and blow up of soil is prevented.Generally, sheet pile cofferdams are only made large enough to allow for the construction of the project within. Because of this, the physical dimensions of the structure govern the shape in plan. However, it should be noted that when conditions permit, circular cofferdam may be preferable. This is because circular cofferdams wales can act as compression rings without requiring struts, thus eliminating the cost of struts and also providing a large clear working space within the cofferdam.

Common Sizes for Cofferdam Pile Beams

Cofferdam pile beams come in a wide range of sizes, including both wide flange piles and H-piles. Some common sizes include:

Engineered forms made of steel or aluminum can be used thousands of times before you have to replace them. To get the most from them and extend their longevity, there are several things you can do maintenance-wise. Below are some tips to help you prolong the life of your forms and ensure they do their job well when they’re in use:

Apply a release agent before each use

You can apply it using a brush or a sprayer. It goes on the face of formwork that will be exposed to concrete. There are many popular and reliable options on the market to help you oil up your forms before they’re used.

Inspect forms carefully before and after each use

Check them for damage and for concrete residue. Make sure to pay special attention to the backs and insides of the formwork to check for buildup/residue.

Remove concrete residue

This is one of the most important ways to maintain your concrete formwork. It’s especially important after each use, but, as mentioned, it’s good to inspect your forms before use for any buildup that may have been previously overlooked. Using water or abrasive blasts is generally the best way to get rid of residue. Rotary brushes or scrapers are also useful in some circumstances.

Appy a release agent after each use

After buildup has been removed, apply another layer of release agent using a brush or sprayer to the face of the formwork that will be exposed to concrete during the form’s next use.

Apply extra release agent to forms that won’t be used for a while

Make sure it’s adequately oiled up before it goes into storage if you know it’s not going to be in use for a month or longer.

Store in a covered area

Avoid leaving steel or aluminum forms outside in uncovered areas. Excessive heat may warp forms, and excessive moisture may cause them to be subjected to corrosion. If you don’t have a covered place to store them safely, you should cover them with a tarp that is waterproof and large enough to adequately shield them from the elements.

Passive Release Agents vs. Active Release Agents

For engineered forms, passive release agents are often the better option. They will leave less dust on the forms. Passive agents usually contain paraffin, diesel oil, or motor oil. Active release agents, on the other hand, use fatty acids like vegetable oils to create a chemical reaction with concrete to make it easier to remove from formwork once the concrete sets. If you end up using a diesel-based passive agent, make sure not to apply too much, causing the oil to bead up.Proper maintenance of your formwork can make a big difference and can help you ensure that it’s usable for the foreseeable future. And, as you can probably tell, maintaining your forms isn’t too difficult. It’s definitely worth it if you consider the price of new forms vs. being able to re-use. Additionally, if you’re looking to sell your engineered concrete forms after a project’s completion, removing concrete residue, using a releasing agent, and storing them properly until they’re sold is essential so that you deliver the highest quality product to your buyer.

Bearing piles are a kind of deep foundation system installed to support vertical loads by transferring the structure’s weight to the soil below. Most commonly, steel pipes are used to create bearing piles.Bearing piles are necessary in one of two situations. First, if there is a weak layer of soil at the surface of a construction site, the soil will not be able to support the weight of a new structure and therefore bearing piles must be used. Second, if the surface soil cannot support the building regardless of the soil’s strength, piling must be used. In both situations, bearing piles will transfer the weight of the structure from the soil’s surface to the stronger soil or rock below.

What Are the Different Types of Bearing Piles?

Bearing piles come in a few main types: H-pile, wide flange, tubular piles and box piles. When piles are fully sunk into the earth, such as those used to create road and railway bridges, H-piles and wide flange are most appropriate. Tubular piles and box piles, on the other hand, work best for aboveground support, such as pier and jetty construction.

What Are the Advantages of Bearing Piles?

Bearing piles have many advantages when compared to other types of pile, including:

1. Easy connection to the superstructure
2. Loads can be set immediately after the pile is installed
3. Highly-durable and long lasting
4. No limit to pile length
5. Easy to install

End Bearing Piles vs. Friction Piles

There are two common types of underground bearing piles: end bearing piles and friction piles. With end bearing piles, the bottom end of the pile rests on an underground layer of strong soil or rock. The end of the pile “sits” on this strong layer and presses against it to keep from shifting. When end bearing piles are used, the load of the aboveground building is transferred through the pile onto the strong underground layer.Friction piles work more like a nail in wood. The friction of the soil around the pile is what holds the pile in place, and this is what transfers the weight of the aboveground load to the soil.

Bearing Pile Installation

Bearing piles can be installed in one of two ways: by cast in place piles or precast driven piles. Cast in place piles are made by hammering a hollow, thin-walled steel tube into the ground. The earth inside the pipe is then removed, and a steel reinforcement cage is lowered into the tube. Finally, wet concrete is poured into the steel pipe to hold it in place.Precast driven piles are first cast at ground level and then hammered into the ground using a pile driver. The pile driver holds the bearing pile vertically and hammers it into the ground by striking it with a heavy weight. The pile is given a temporary cap to avoid damage while it’s being hammered. The pile is hammered until “refusal,” when it will physically go no farther.

Common Sizes for Bearing Piles

Bearing piles come in a wide range of sizes, including both wide flange piles and H-piles. Some common sizes include:
