South Carolina Department of Transportation’s temporary concrete barrier general notes are as follows:

Fabrication Requirements

1. All approved temporary concrete barrier walls should comply with the standard drawings and the requirements of NCHRP Report 350. All acceptable barrier wall designs are included on the “Approved Products List for Traffic Control Devices in Work Zones” maintained by traffic engineering. All manufacturers of approved temporary concrete barrier walls and their barrier wall products should obtain inclusion on the “Approval Sheet 54 Temporary Concrete Barrier Producers” maintained by the Office of Materials and Research. Omission of either the barrier wall design or the manufacturer from these lists will disqualify a barrier wall design for use on a SCDOT project.
2. Temporary concrete barrier walls should be constructed of Class 3000 concrete unless otherwise specified. Reinforcing steel should be ASTM A-706, low-alloy steel deformed and plain bars for concrete reinforcement, Grade 60.
3. ASTM A-36 steel should be used for the connection. Fabricate all connection hardware as detailed.
4. A 4” white PVC sleeve may be used to form the lifting hole if the sleeve is left in place.
5. The temporary concrete barrier walls should have the SCDOT 350 approval stamp, “SCDOT 350 XX 00 00” imprinted on top of each section of barrier wall, but no closer than 12” from either end of each section of barrier wall, unless otherwise directed by the Department.
6. Acceptance of the temporary concrete barrier wall is dependent upon the successful inspection of the manufacturer’s plants and the manufacturing process of the products by representatives of the Department’s Office of Materials and Research. The manufacturer will imprint the date of acceptance on top of each section of barrier wall as part of the approval stamp.

Installation Requirements

1. All temporary concrete barrier walls are subject to inspection and approval by the Engineer prior to installation.
2. Install the temporary concrete barrier wall the maximum distance from the near edge of the adjacent travel lane while providing sufficient space to conduct the work.
3. All temporary concrete barrier walls installed in a continuous line should be the same shape, length and connection type.
4. Improperly placed approach tapers and temporary concrete barrier ends can be hazardous to motorists. Crash severity may be amplified depending upon a vehicle’s speed and angle of impact. Provide protection to minimize the possible hazardous conditions of the approach areas and the barrier ends.
5. A portable terminal impact attenuator should comply with all requirements as specified by the standard specifications unless otherwise directed by the Department. Each attenuator should be one of three types. Selection of the proper unit should be determined by the performance characteristics of the unit in correlation with the posted regulatory speed limit of the adjacent roadway prior to installing the permanent construction signs and initiating construction activities.
6. When placing temporary concrete barrier walls on a bridge deck to provide a temporary railing, anchor the barrier wall to the bridge deck to minimize the potential for displacement that could render the wall ineffective. Anchor the wall to the deck where there is 8’ or less of deck between the wall and the nearest edge of the deck.
7. When connecting the end of a line of temporary concrete barrier wall to a structure, install and stabilize the last two sections of the wall to minimize movement of the ends as directed by the standard drawings for road construction.
8. Utilize and install only those temporary concrete barrier walls designed for anchorage and included on the approved products list.
9. Only install anchors on the traffic side of the temporary concrete barrier wall.
10. Install each anchor in accordance with SCDOT requirements regarding anchorage of temporary concrete barrier walls to bridge decks.
11. Attach the small delineators to the sides of the temporary concrete barrier wall as detailed in the standard drawings for road construction. Attach large delineators to the tops of the temporary concrete barrier walls as detailed in the standard drawings.
12. Color each section of the temporary concrete barrier wall “bright white.”
13. Refer to details, notes and quality items as provided and specified by the standard specifications.
14. During high speed angle impacts greater than 10 degrees, a deflection of the barrier wall is likely to occur. However, deflection may occur during any impact. Therefore, do not place equipment within 6’ of a barrier wall when space is available to minimize risk factors.
15. The pay items should be listed as: Temporary Concrete Barrier L.F.

Jumpform, also known as jump system formwork, and slipform are both used in construction involving concrete. They are most often self-climbing forms that are used in the construction of tall buildings or other sizeable structures. They are particularly useful for the creation of shafts and cores as well as bridge pylons, silos, and chimneys. Jumpform as well as slipform may be referred to as a “climb-form” system.

Similarities

With both jumpform and slipform, concrete is poured into self-climbing molds until a concrete structure reaches a desire height. Electric motors or hydraulic rams may help facilitate the vertical climbing of these types of forms, eliminating or reducing the need for cranes. Jump system formwork and slipform both make use of work decks or platforms that climb vertically as the forms do to allow for the completion of concrete pours and reinforcement at various levels with ease. Neither jumpform nor slipform requires support from other parts of a building or construction. They are self-supporting, as they hold themselves up using the concrete that has been cast below each of their vertical levels or using other built-in support systems.As you can probably tell, these form systems have quite a bit in common. There are some things that differentiate them from each other, however. Below are some of their key differences.

Jumpform Differences

The use of jumpform involves a progression of a series of “jumps” or levels of concrete pours. On each level, concrete is poured and sets before jumping or progressing to the next level. This ensures a supportive foundation to move up. For instance, if jumpform is designed to produce ten-foot sections, concrete will be poured and set in the first ten-foot section. After which, the form will “jump” up to the next level, and concrete will be poured into the second ten-foot section. This process will continue until a structure reaches the necessary height. Jumpform is well-suited to applications in which any joints in between levels will ultimately be concealed in the final construction of the building or structure.There are a few different types of jumpform. These are the most common:

• Traditional Jumpform – This type involves using a crane to lift formwork to each level.
• Guided Jumpform – This is really similar to traditional jumpform except that formwork units stay attached/anchored to the concrete structure as formwork is raised by a crane. Guided jumpform can be a bit safer than traditional jumpform.
• Self-climbing Jumpform – No crane is needed for this category of jumpform, as it’s raised to new levels on rails.

Slipform Differences

As we’ve mentioned, slipform has a lot in common with jumpform. The main difference between the two is that slipform uses a structure’s core of shaft for its support, and it moves up slowly as concrete is poured in one long, slow pour. This eliminates the need for waiting for each level to dry. Slipform is great for creating tapered structures with walls that have thickness that contracts at various levels. In general, this type of self-climbing formwork system is considered to be more efficient than jumpform for particularly high buildings, especially those over ten stories. Slipform usually consists of three platform stations. The lowest station is used for the finishing of concrete. The middle station is used at the highest level of where concrete is poured, and the highest station is where materials for the project are stored.Slipform creates a continuous, smooth, and highly precise concrete end product with no joints from jumping. This is ideal for structures where joints won’t be covered up, particularly for structures like chimneys and bridge pylons. A downside of slipform in comparison to jumpform is that it’s usually a bit more expensive, and it requires workers to attend to concrete pours for longer consecutive hours.Overall, both jumpform and slipform come with unique advantages that make them excellent choices for the efficient construction of tall concrete structures.

Bridge overhang brackets are a vital part of the concrete formwork used in the construction of bridge deck overhangs. Overhang brackets secure and support all of the other formwork used in the creation of overhangs. They are commonly made of steel and built to withstand heavy loads and significant pressures. Installation of bridge overhang brackets is usually fairly quick and simple. There are even types of bridge overhang brackets that are engineered to be able to be installed as a group all at once. Most types of these brackets can be affixed to concrete beams, concrete box beams, or steel beams. Bridge overhang brackets are removed once the desired concrete shape for a bridge deck overhang has set. After they are removed, they can be re-used or sold.

MOST POPULAR TYPES

The various types or categories of bridge overhang brackets differ based on capabilities, size, and adjustment qualities. For the purpose of this article, we will be discussing the different types of bridge overhang brackets produced by Dayton Superior, a popular overhang bracket manufacturer. The list of types of bridge overhang brackets below helps illustrate the scope of possibilities offered by these formwork components.1. C49 – This is the basic overhang bracket in the C49 series. It’s a versatile option and boasts a horizontal length of 54 inches and a vertical adjustment range of 30 inches to 50 inches.2. C49D – Meant for use on bridge structures with deep beams, this category of overhang bracket is pretty similar to the C49. However, it comes with longer legs, vertically and diagonally. Like the C49, its horizontal length is 54 inches. Its vertical adjustment range is 50 inches to 70 inches.3. C49S – A top choice for use with shallow beams, the C49S is a modified type of bracket. It has a removed inner vertical leg. With the use of its outer vertical leg, it can be adjusted to a vertical height of as little as 14 inches. Its horizontal length is 54 inches, and its vertical adjustment range is 14 inches to 28 inches.4. C49W – This type of C49 bracket is designed to prevent bending of the web of beam during bridge overhang deck construction.5. C49JR – This is the “junior” option in the C49 series. It is ideal for use when dealing with a limited amount of space between twin bridges. Its horizontal length is 27 inches, and its vertical adjustment range is 16 inches to 28 inches.6. C89 – The C89 series of bridge overhang brackets are considered “heavy-duty,” which means they are extra-long and extra-strong and offer a significant amount of support for heavy vertical loads. The C89’s horizontal length is 72 inches.7. C89L – This type of heavy-duty bridge overhang bracket is engineered to offer the most strength and adjustability. Its horizontal length is 90 inches, and its vertical adjustment range is 30 inches to 68 inches. An exterior hanger attachment is typically used with this type of overhang bracket.

FINAL THOUGHTS

These are just some of the options on the market from one specific manufacturer of bridge overhang brackets, but they offer a look into how many choices are available to companies searching to find the right fit for their bridge deck overhang construction project.

Bridge overhang brackets are a component of concrete formwork used for the creation of bridge deck overhangs. Bridge overhang formwork systems are typically made up of a combination of plywood sheathing, timber joists, and steel or aluminum overhang brackets. Steel is the most common material used for bridge overhang brackets. Overhang brackets support all of the other components used to create the necessary formwork. Bridge overhang brackets are commonly attached to a bridge structure using coil rods and hangers. Brackets are installed on each side of a bridge deck in order to hold up formwork as well as workspace for the construction of the overhang. In addition to being used for bridge overhang formwork, some bridge overhang brackets may also be used for other formwork applications like water treatment plant trough wall construction or perimeter work platform construction.

Benefits of Bridge Overhang Brackets

Bridge overhang brackets are a handy tool for minimizing the work and effort required to create high quality concrete bridge overhangs. They are safe and sturdy. Installing them is as simple as assembling them on the ground and then setting them in place with a few maneuvers on a bridge deck. Installation of each individual bridge overhang bracket only takes a couple of minutes at most. Some overhang brackets are even designed to all be installed at once as a gang assembly. These types of overhang brackets make use of bolts that can connect the brackets instead of clips or clamps for individual installation. Bridge overhang brackets are also very versatile and can be affixed to structural steel beams, precast concrete beams, or concrete box beams.

Resale

Once concrete is poured into a bridge overhang formwork system and sets, bridge overhang brackets as well as other parts of the formwork system are usually removed. The brackets can be re-used for other projects or sold. Whether purchased new or used, most bridge overhang brackets can be disassembled to conserve space and fit neatly in shipping boxes or containers. The same goes for selling used bridge overhang brackets. Sellers can cut shipping costs (if shipping is necessary) by disassembling them or “knocking them down.” Re-assembly of bridge overhang brackets is fairly simple once they’re ready to be used again.

Types of Bridge Overhang Brackets and Cost

There are various types of bridge overhang brackets on the market. Types differ in terms of size, adjustability, and capabilities. Dayton Superior, a top bridge overhang bracket manufacturer, for instance, offers the following types of brackets in its C49 series: C49, C49D, C49S, C49W, and C49JR. Dayton Superior also offers heavy duty brackets in its C89 series, including their extra-long C89L. Each of these types of overhang brackets offers specific adjustability settings to suit specific requirements of various steel and concrete bridge designs. Bridge overhang brackets range in price from around $40 per bracket to $100 per bracket. Their price depends on their condition and their features. New brackets are a bit more expensive than used brackets. Overhang brackets retain their value quite well for contractors who decide to sell them. There is a great used market for overhang brackets, so purchasing used is an affordable option for contractors on a budget.Bridge overhang brackets are a vital component of bridge overhang formwork systems, and for all the reasons we’ve mentioned and more, they’re an excellent investment for bridge construction projects.

The Vermont Department of Transportation outlines general notes regarding the proper installation and components of temporary traffic barriers.Vermont Temporary Traffic Barrier Specifications

The Vermont Department of Transportation’s general notes are as follows:

1) Temporary traffic barriers should be one of the barriers included under FHWA’s Roadside Hardware Policy and Guidance for crashworthy longitudinal barriers, at the Contractor’s discretion, unless otherwise specified.2) The type of temporary traffic barrier should be provided to the Engineer prior to use.3) All temporary traffic barriers and corresponding connections should meet (unless otherwise specified in the Plans) Test Level 3 (TL-3) criteria as defined in NCHRP Report 350 or the AASHTO Manual for Assessing Safety Hardware (MASH). The appropriate resource should be determined as described in the MASH publication.4) Temporary traffic barrier components should be in a condition satisfactory to the Engineer prior to placement on the project and maintained as such until removed from the project.5) The Contractor should provide to the Engineer verification that the barrier deflection distance is appropriate for the intended use. Where appropriate, temporary traffic barriers should be adequately anchored to prevent movement if impacted.6) Temporary traffic barriers should be erected in accordance with details shown on the Plans or as directed by the Engineer. Unless otherwise specified, temporary traffic barriers should be removed when no longer needed on the project as determined by the Engineer, and should remain the property of the Contractor. The area from which the barrier was removed must be restored to a satisfactory condition where and when no other construction activities are indicated.7) Temporary traffic barriers and required appurtenances should be removed and reset as shown on the Plans or as ordered in writing by the Engineer.This blog post is an interpretation of specifications by the Virginia Department of Transportation.
