The Texas Department of Transportation outlines specifications regarding the proper dimensions for Type 1 single slope concrete barriers with pinned placement, including general notes, section details, and more.

Texas Single Slope Concrete Barrier Type 1 Pinned Placement General Notes

The Texas Department of Transportation’s general instructions are as follows:

1. These details provide a method of laterally restraining precast concrete barrier to limit deflection under normally expected passenger vehicle impacts. These details are intended for use in work zones, primarily on bridge decks, or pavement where temporary barrier must be placed less than 2 feet from the longitudinal edge of the deck or drop off and parallel to the direction of travel. Other applications of these details are acceptable as directed by the engineer.
2. Each precast concrete barrier section should have a minimum of four or total of eight 1-3/8” ID holes formed or cord through the barrier. The center lines of the holes are shown in the whole location detail. If rebar is encountered, the entry point may be shifted to inches plus or minus longitudinally along the barrier. The eight holes are spaced along the length of the barrier as shown in detail one.
3. The drilling of the travel service is accomplished by placing the pre-drilled barrier section on the travel surface in the desired position. Then the hole is drilled with the bit passing through the hole in the barrier. The bit is to be inserted into the hole in the barrier so that the travel surface is drilled to a point which is slightly more than the pin length.
4. Note that steel washers have been welded to the top of the steel pins to aid in the removal of the pins, when the barrier is removed.
5. See SSCB (2) to standard sheet for reinforcement requirements and joint connection types.
6. The forming or coring of holes in the barrier drilling of holes in bridge deck or pavement, fabrication and materials for the pens, installation of pins, and any repair to the barrier should be considered as subsidiary to the barrier bid items.
7. The barrier and travel surface will be repaired as directed by the engineer in accordance with Item 429, “Concrete structure repair.”
8. All steel pins should be galvanized after fabrication in accordance with Item 445.
9. The weight of barrier is approximately 700 pounds per foot.

Texas Single Slope Concrete Barrier Type 1 Pinned Placement Details

Barriers should conform to the following specifications, according to the Texas Department of Transportation.Detail 1Barriers measure 30” long and include 1-3/8” diameter holes, which are arranged in pairs along the barrier. Each hole in a pair is spaced 7” apart. The pairs of holes are spaced 6’-9” apart from each other, and 4’-3” away from either end of the barrier (when measured to the nearest hole).Detail 2Detail 2 depicts placement on asphalt concrete pavement (ACP) or treated base materials. In this instance, a 30” pin is required. Cross pins should be used if traffic is on both sides of the barrier and there is less than 2’-0” of slide room. The front or traffic side pin will be fit into a 1-3/8” diameter hole (typ. front and back).Detail 3Detail 3 depicts placement on a bridge deck or CRCP. In this instance, a 27” pin is required. Cross pins should be used if traffic is on both sides of the barrier and there is less than 2’-0” of slide room. The front or traffic side pin will be fit into a 1-3/8” diameter hole (typ. front and back). Cross pins are recommended but not required if there is less than 2’-0” on the bridge deck.Core DrillingCore drilling existing concrete barrier is permitted. Holes should be drilled with coring or masonry drilling type equipment. Percussion drilling should not be used. A special drill bit to cut through existing reinforcing will likely be required. Spalls in the concrete exceeding ½” should be patched.Precast SSCB Placement Over Longitudinal Expansion JointThe “Bolt Through” method of pinning precast barriers on a bridge deck is primarily used in a permanent location that requires limited barrier deflection.There is a grout recess at the top of the barrier where the barrier bolt is placed, and a 3-1/2” x 3-1/2” recess (spread reinforcing steel at the top to clear recess by ½”).There is a 1” diameter bolt and hex nut running vertically through the center of the barrier into the deck below (the bolt length will vary). Barriers include a 1-1/2” ID Hole (formed or cored) and a void at the bottom for conduit where applicable (with a 2” radius).This blog post is an interpretation of specifications by the Texas Department of Transportation (TxDOT). Please consult with TxDOT' most recent requirements for definitive information.

Concrete formwork is a mold or frame that holds wet concrete (poured into the formwork) until it dries and creates the desired structure that suits the purposes of a construction project. Concrete formwork can be temporary or permanent. When it is temporary, it is removed once the concrete sets. Temporary formwork is more common than permanent formwork. It can be re-used for other projects once it is no longer needed, which is of great benefit to the contractor. Because of this, temporary formwork can be resold after a project or reused on a later job. Temporary concrete formwork can be made of heavy-duty aluminum, steel, plastic, plywood, or timber. Permanent formwork, which remains in place and becomes a part of the construction after the concrete sets is often made of foam material.The process of using concrete formwork in construction is sometimes referred to as “shuttering.” A major benefit of using concrete formwork is that it aids in achieving a desired concrete shape with a great degree of precision. Use of formwork as opposed to other methods of setting concrete is quick and efficient.

Concrete Formwork Projects

Below are some of the types of projects in which concrete formwork is used:

• Building construction (residential, commercial, skyscrapers, airports, high rises, etc.)
• Bridge construction
• Highway construction
• Overpass construction
• Industrial and energy construction
• Viaduct construction
• Tunnel construction
• Wastewater treatment plant construction
• And more!

Formwork has been a vital component of architecture projects since its use in Ancient Rome to help construct monuments like the Pantheon and the Colosseum. Its longevity in construction is due to its usefulness and reliability.

Styles and Types of Formwork

Formwork comes in various shapes, sizes, and styles to suit the needs of individual projects. Column forms, box culvert forms, and bridge overhang brackets are all popular styles. In addition to coming in different styles, there are various types of formwork classified based on their materials as well as their uses. Below are some of the most popular types of formwork:

• Engineered formwork systems – These are prefabricated structures with metal frames (typically aluminum or steel). They are quick to install and use and easy to remove once concrete sets. Plus, they are durable, which means they can be re-used and re-purposed for several other projects.
• Timber formwork – This is a popular choice. Installation can take a bit longer than it does with steel or aluminum formwork, and timber is less durable so it can’t be re-used for a great number of projects without degrading to the point that it’s no longer viable.
• Permanent insulated formwork – This is the most common type of permanent formwork. As mentioned previously, it’s usually made of foam and remains in place once concrete sets. A benefit of using this kind of formwork is that it can improve the thermal conditions of a structure, i.e. keep a building better insulated from changes in outside temperature.
• Plastic formwork – These are modular and interlocking structures that can easily be built to size and desired shape and removed when the time comes. They are a good choice for mass housing projects that require low costs and simple concrete formwork systems.
• Stay-in-place formwork – Made of plastic and easily installed on site, this type of formwork is often used for column applications and pier construction. It’s a permanent type of formwork than can reinforce the strength of concrete structures.

The best type of formwork or style of formwork for a project will hinge upon its particular needs. Overall, concrete formwork is a smart addition to numerous kinds of construction projects and will remain a staple in the construction industry for the foreseeable future.Interested in learning more about concrete formwork?

The Texas Department of Transportation outlines specifications regarding the proper dimensions for Type 2 precast concrete traffic barrier (PCTB), including general notes, plan view details, elevation view details, and more.

Texas Low Profile Precast Concrete Barrier (Type 2) General Notes

The Texas Department of Transportation’s general instructions are as follows:

1. Welded wire reinforcement (WWR) is not an option for Type 2 barriers.
2. Type 2 barriers should be used as an end treatment for the Type 1 barrier segments, when applicable.
3. The end treatment can be used without the anchor pins in locations that can accommodate approximately four feet of lateral displacement of the end treatment. The use of non-pinned end treatment does not affect the performance or the deflection of the low profile barrier system.
4. The anchor pins are all the same length and are to be driven flush with the top of the Type 2 barrier surface.
5. The bends in the H3 and H1 bars are slight, no formal bend is necessary.
6. The Type 2 low profile barrier wall segments must be lifted from the rear first, to prevent cracking of sloped sections.

Dewatering removes water and/or controls water currents to ensure the safety of job sites for construction or repair projects involving bridges, dams, boat ramps, ships and other vessels, canals, pipelines, diversion pipes, utility lines, etc. Dewatering occurs through the process of removing water, storing water, pumping it, and discharging it to a different location. It can happen with the help of structures like cofferdams, caissons, and inflatable cofferdams. These structures aid in preventing issues during construction due to water, flooding, and erosion.

Cofferdams

These structures, also called “coffers,” are sealed, enclosed areas situated across bodies of water where water is removed (and cannot re-enter). Construction can safely take place within the confines of a cofferdam, as the structure creates a dry environment. Cofferdams are most often temporary fixtures. Once construction is complete, they are removed, and the materials used for their initial construction can be re-used or re-purposed for future projects involving cofferdams or for other purposes. Cofferdams are made of steel sheet piles, concrete, and other durable materials that keep water out. Those that are made of steel sheet piles create a wall that is driven into the earth quickly and efficiently. Steel sheet pile cofferdams can be installed and uninstalled easily once construction is over.

Caissons

These dewatering structures are often made up of hollow boxes or cylinders that are floated to particular areas, where they are inserted and secured deep into the earth. Once they reach a desired location, water, mud, etc. is pumped out of them until they reach bedrock or clay, at which point a dry environment is created. A caisson is usually filled with concrete once it is set up in its final location. This creates a safe and dry work platform, and it also can serve as a component of the foundation of the construction. If a caisson is intended to be a part of the construction, as is often the case, it is a permanent structure. Caissons are constructed using concrete, wood, steel, or a mix of those materials. Some of the popular types of caissons include box caissons, open caissons, pneumatic caissons, excavated caissons, and floating caissons, which all are best suited to particular types of applications and environments.

Inflatable Cofferdams

Designed to be temporary and portable, these are convenient choices for dewatering. They are made of a fabric, usually composed of polyester and vinyl (or some combination). They are inflated with water and placed in an area that needs to be dewatered. Once in place, the water is pumped out, and a watertight work environment is facilitated. Inflatable cofferdams come in a variety of shapes and sizes to meet the needs of particular projects and can be customized. Although most often used as temporary structures, inflatable cofferdams may also be utilized as permanent faults in streambeds and rivers. Inflatable cofferdams are fairly easy to repair/patch up and also to deflate and re-use elsewhere. When they are deflated, storing them is also quite simple. Although inflatable cofferdams work well in many scenarios, they are not as strong against pressures as traditional cofferdams made of steel sheet pile. In areas where pressure from surrounding water is immense, they are not always the best choice.The structures mentioned above are all excellent dewatering solutions for marine construction. Each comes with specific benefits. For instance, for temporary applications, cofferdams and inflatable cofferdams are a solid choice, with traditional cofferdams being the better option for areas in which water pressure is greatest. And caissons are best-suited to foundation projects in which they are built into the constructions.
