Cast-in-place barrier forms are a type of concrete formwork. Concrete formwork plays an important role in a variety of construction projects, including road, bridge, and highway construction projects, as it serves as a mold for wet concrete to be poured into in order to create a desired concrete final product of a needed shape and size. Cast-in-place barrier formwork is used to create median barriers or median parapets on the spot. The forms are transported to the necessary area for a project. Then, concrete is poured into them and sets. Once it’s done setting, the forms are removed and can be re-used for other projects. Barrier formwork is typically made of steel but may sometimes be made of aluminum or other materials.

Cast-in-Place vs. Precast

The difference between cast-in-place barrier walls and precast barrier walls is that the former uses cast-in-place barrier forms to allow concrete shapes to be constructed directly at a project site. Precast concrete barrier walls are already in the desired shape, size, and style, and they have been cast somewhere other than the project site. Additionally, precast barrier wall is typically used for temporary projects while cast-in-place is typically used for permanent applications. One of the main advantages of using cast-in-place barriers is that there’s less logistical effort required to transport heavy concrete slabs to a project location.

Styles of Cast-in-Place Barrier Forms

These forms can come in numerous styles to meet the needs of a project. They are available in all popular barrier styles including:

• New Jersey
• F-Shape
• Vertical
• Texas T5 Modified Bridge Rail (Roman Rail)
• Temporary Barrier Rail
• Hinged Barrier Rail
• Slope
• Ontario Tall Wall Median Barrier
• Barrier Wall with Head Ejection

Cast-in-place forms are also available for median barrier caps and other concrete structures that complement the use of barriers.Barrier styles used for particular projects often differ based on local regulations. Cast-in-place barrier forms can be created at the necessary shape and size to meet any and all local requirements, and they are widely available and easily obtainable in the most common styles.Wadco, Symons, Southern Forms, and Wharton are some of the popular manufacturers of barrier formwork. All of these manufacturers offer barrier forms that are of the highest quality, allowing for the production of concrete barriers that are precise in size and shape as well as durable and strong.Keep in mind that regulations at the state or national level may apply to how cast-in-place barrier forms must be used. For instance, in Massachusetts, barrier formwork should not be removed until concrete has been allowed to dry and set for at least 24 hours.

Buying and Selling Cast-in-Place Barrier Forms

Cast-in-place barrier forms can be purchased either new or used. For projects that require common styles, finding used options of the appropriate barrier formwork is quite easy and can save contractors some money. For projects that necessitate uncommon shapes, sizes, or styles of cast-in-place barrier forms, buying new may be the best decision. Used cast-in-place barrier forms cost, on average, between $100 and $150 per linear foot of formwork. New barrier formwork tends to cost a bit more. Once a project is finished and formwork is no longer needed, it can definitely be a good financial decision to try to sell barrier forms if they cannot be re-used for another project.

Plate girder formwork systems are a type of concrete formwork produced by top formwork manufacturers like EFCO. Concrete formwork is a mold into which wet concrete is filled, after which the concrete dries and creates a desired shape and size for the purposes of a construction project. Plate girder formwork systems are steel molds that take the shape of plate girders. They are suited to applications in which plate girders are employed and extra reinforcement/strength from concrete is needed as opposed to what traditional I-beams can offer. They are ideal for the creation of large spans of plate girder walls as well as large spans of plate girder sections of bridges. They act as supporting structures however they are used.

Plate Girder Formwork Systems Applications

Plate girder formwork systems can be used in the following areas of construction, among others:

• Bridge construction
• Railway bridge construction
• Stadium construction
• High-rise construction
• Power plant construction
• Oil and gas platform construction
• Load testing
• Other long span applications

Benefits of Plate Girder Formwork Systems

As with all formwork, plate girder forms create perfect concrete modules and make precision easy for workers. Plate girder forms make highly supportive and reliable structures. They are engineered for setting as well as flying in sections of substantial lengths, and they are self-spanning. They come as modular panels, which can easily be conjoined to make forms of necessary spans, tailored to the needs of particular projects. Their modules can be connected both length-wise and width-wise. They are sold in various sizes ranging from around 2'x4' to 10'x10'. They typically have entirely steel face sheets, which offers a consistency to their finish. Their steel ribs act as web stiffeners and beams, transferring pressures from wet concrete away from their face plates to their bottom flanges and panel tops. This ensures a high-quality pour and setting for concrete as well as guaranteed integrity of all steel parts of the formwork.Ultra-strong plate girder formwork systems specifically for bridge construction applications exist to help offer adequate strength and safety when it’s needed most. These systems come with extra spanning strength and extra pour pressure resistance, among additional perks. Overall, they are a great choice for the heaviest duty jobs. EFCO’s “Super Plate Girder” forms belong to this category of plate girder formwork systems and are a popular choice.

Buying Plate Girder Formwork Systems

You can buy plate girder formwork systems both used and new, since forms can be used after a project’s completion. The price for used forms is usually around $15 to $25 per square foot or around $50,000 to $80,000 total for the needs of an average project. New plate girder formwork systems are a little more expensive, often starting at around $30 per square foot. Plate girder formwork systems are an excellent investment because they retain their value after use (and several uses at that). They’re built of steel materials that are intended to last for the long haul. Selling them after you no longer need them can definitely be a lucrative financial decision.

Column formwork is a type of concrete formwork. Concrete formwork is a mold made of steel, aluminum, timber, plastic, or other materials in which wet concrete is poured to achieve a desired shape and size for construction. Once the concrete sets, formwork is often removed, although permanent formwork that remains a part of construction exists as well. Column formwork is a vertical mold in the shape of a column, as its name implies. Column formwork may either be box-shaped or round.Column formwork is shaped and sized to the needs of a project. In order to help facilitate quality control during the pouring stage of using column formwork, clamps, which are horizontal and made of either steel or timber are often used in conjunction with column molds. Column formwork’s head is frequently employed to support beam formwork, or column formwork is cast to the bottom side of beams. The use of column formwork in conjunction with beam formwork allows for quick and precise construction.Two of the major benefits of using column formwork include that it is quick and simple to assemble and that it reduces the amount of labor and equipment needed to successfully produce uniform and strong vertical concrete shapes of desired dimensions.

Projects Involving Column Formwork

Column formwork is used in corporate building construction, retail building construction, residential building construction, industrial construction, bridge construction, power plant construction, infrastructure construction, and sewage treatment plant construction, to name a few areas where it’s applicable. Most construction projects that require the creation of vertical concrete columns (square or round) benefit from the use of column formwork, thanks to its ability to help create clean, precise, and strong concrete columns.Once the concrete sets in column formwork, it is necessary that it is thoroughly inspected to ensure it meets the necessary standards of the project in terms of factors such as appearance and strength. As concrete is being poured, column formwork is often bolstered with the help of falsework. Falsework includes poles or other stabilizing elements that keep the column formwork in place until the concrete dries.

Price of Column Formwork

Column formwork can be purchased either new or used. Average prices for new column formwork range between around $60 to $150 per square meter of materials. These prices apply to plastic, steel, and aluminum formwork. Prices are fairly consistent regardless of the materials used. At times, timber formwork can be a little less expensive, but it’s also less likely to retain its value and ability to be re-used and/or sold after use. In terms of resale, column formwork retains its value as long as it’s in good condition. Once temporary column formwork is no longer needed for a particular project, it can be re-used for another project or sold to buyers who are looking to cut costs and purchase formwork used. Sometimes column formwork is sold with falsework, access equipment such as ladders, and guard rails. This will increase the price, but these add-ons can be very helpful.Overall, column formwork can be an indispensable addition to construction projects that require the creation of columns. Whether column formwork is bought new or used, it often practically “pays for itself” in terms of the value it adds to a project and due to its resale value.

Jump system formwork, also called jumpform, is a kind of climbing concrete formwork utilized in the construction of large, vertical concrete buildings and similar structures. Jumpform system formwork holds itself up using a concrete cast, and it does not necessitate the use of support from the building or other bolstering systems. Jumpform is a great solution for the construction of buildings that are made of sections that are the same shape and size. It is used in the building of shear walls, lift shafts, core walls, bridge pylons, and stair shafts, among other structures. It is very helpful in the construction of skyscrapers, for instance, because the bulk of their structure is a continuous wall. Using jump system formwork allows for quick and simplified builds.

How Jump System Formwork is Used

The process of using jump system formwork is often fairly straightforward. In a typical example of self-climbing jumpform, the jumpform installation process begins with a starter being cast at a construction site. Then, vertical re-bars are secured in place and shutters are aligned with the use of props. Next, concrete is poured into the first segment or module of the building. Temporary supports and shutters are then taken out and brackets are affixed to the concrete’s walls. Afterwards, a working platform/deck is installed on both the outside and the inside of the building. This process leads to re-bars being installed at a higher level than before. After which, shutters and props are able to be mounted using the working platform. Concrete is then poured into the second segment or module of the building.The process continues with props being taken out and the concrete being cured. A second set of brackets is then mounted, and hydraulic jacks are installed between lower and upper brackets. Next, extension posts as well as horizontal frames are affixed atop the hydraulic jacks, and shutters are affixed on top of runners that are held up by the frame. At which point, the next level of concrete is poured and cured. And then the hydraulic jacks move the framework structure up to the desired next level/module of construction. Upper brackets are used to latch the climbing formwork in place at the new level, and cylinders are shut to move the lower brackets up. Finally, re-bar is added to create an additional level for concrete to be poured, and the process is repeated until the building is the desired height.

Climbing Jumpform

In addition to self-climbing jumpform, normal climbing jumpform is also common. This type of jump system formwork uses a crane to lift jumpform up to higher modules. Guided climbing jumpform is another option. It utilizes a crane for moving formwork up, but the formwork is anchored to boost safety and efficiency.

Benefits of Jump System Formwork

• Speeds up construction of vertical structures
• Self-climbing formwork eliminates the need for crane use
• Facilitates a superior quality and precise concrete finish
• Simplifies planning of repetitive construction
• Ensures safety of workers, offering a sturdy platform for the job
• Using jump system formwork is a straightforward process for employees

Once a building is complete, and jump system formwork is no longer needed, it is detached from the building, and its materials can be used elsewhere to help build a new structure using the same process.
