Rebar Tensile Strength Testing

As part of our quality assurance testing scope of services, BSK performs rebar tensile strength testing including measurement of elongation as shown here. This testing provides several key benefits:

Benefits of Rebar Tensile Strength Testing

  • Ensures Structural Integrity: The primary purpose of tensile testing is to ensure that the rebar can withstand the forces it will encounter in a structure without failing. This is vital for the safety and longevity of any construction project.
  • Assessment of Material Properties: Tensile strength testing helps in determining the ultimate tensile strength, yield strength, and elongation of the rebar. This data is essential in assessing whether the rebar meets the required specifications and standards for construction materials.
  • Elongation Measurement for Ductility: Measuring the elongation of rebar during tensile testing provides insights into its ductility. Ductility is a measure of how much a material can deform without breaking. In construction, higher ductility in rebar is often desirable as it allows the material to absorb and dissipate energy during events like earthquakes, reducing the risk of catastrophic failure.
  • Quality Control and Compliance: Regular tensile strength testing ensures consistent quality in the manufacturing of rebar. It helps in identifying production issues early, thus maintaining the quality of the rebar. This process is also crucial for compliance with regional and international building codes and standards.
  • Predicting and Preventing Failures: By understanding the tensile properties of rebar, engineers can better predict how structures will behave under load. This knowledge helps in the design of safer and more efficient structures and in preventing construction failures.
  • Public Safety and Confidence: High-quality construction practices, validated by rigorous testing, contribute to public safety. Furthermore, it fosters public confidence in the integrity of buildings and infrastructure.

In summary, tensile strength testing and elongation measurement of rebar are fundamental for ensuring the safety, compliance, and durability of construction projects. Click here for guidelines on rebar tensile strength testing.

Meadows Field Airport

Meadows Field Airport

From 2016 to current BSK has provide geotechnical investigation and construction material testing to support Meadows Field Airport on their major design and construction projects. The work on Runway 12L-30R has been completed in three phases over four years. The runway opening means the airport can more effectively keep the takeoff and landing of heavier commercial aircraft separate from smaller, lighter planes. Having both runways open and operating also helps keep Meadows flexible as demand grows and circumstances change.

The cost of this third and final phase of the runway project including construction, administration, inspection, and material testing was $14.5 million. In total, the cost of rehabilitating Meadows Field’s main runway is nearing $50 million.

 

County of Kern, Meadows Field Airport Runway 12L-30R Rehabilitation, Bakersfield, CA

BSK provided geotechnical engineering during the design phase and QA construction material testing services during the construction phase of the project. The existing runway is approximately 150 feet wide and is approximately 13,000 feet in length. Nineteen taxiways are included within the limits of the project. BSK’s responsibilities included providing geotechnical data compatible with FAA AC 150/5320-6 Airport Design and Evaluation Requirements. BSK’s geotechnical investigation included a total of sixty-one (61) geotechnical borings at the existing runaway and an additional sixteen (16) core-only locations. Special challenges include coring the existing pavement section with thicknesses up to 24 inches and work within an active runway. BSK’s geotechnical investigation was performed at night between the hours of approximately 12am (midnight) and 5:30am. Site preparation recommendations included subgrade re-compaction recommendations and recommendations for aggregate base placement and compaction. The geotechnical laboratory testing included California Bearing Ratio, particle size, soil corrosivity, in-place moisture content and dry density, Atterberg Limits, and moisture-density relationship testing. During the construction phase of work, BSK provided QA oversight during paving operations including aggregate base course sampling, concrete sampling, laboratory compaction of Marshall briquettes at the production plant, HMA core sample pick up, laboratory testing and preparation of daily field and laboratory test reports.

EPAs new plan to combat PFAS

EPAs new plan to combat PFAS

EPAs new plan to combat PFAS

 

The Environmental Protection Agency (EPA) has announced new plans to combat per- and polyfluoroalkyl substances (PFAS). The EPA released four new drinking water health advisories to aid in America’s plan to furnish clean drinking water. Additionally, the EPA announced fresh fiscal opportunities to combat PFAS pollution through a $1 billion grant.

“Today’s actions highlight EPA’s commitment to use the best available science to tackle PFAS pollution, protect public health, and provide critical information quickly and transparently,” said EPA Assistant Administrator for Water Radhika Fox.

These updated health advisories are based on the newest science regarding PFOAS and PFOS. Further, the new advisories will replace those for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) issued in 2016. Moreover, EPA is issuing final health advisories for perfluorobutane sulfonic acid and its potassium salt (PFBS) and for hexafluoropropylene oxide (HFPO) dimer acid and its ammonium salt (“GenX” chemicals). This will be the first time the EPA has issued these health advisories.

$1 billion Bipartisan Infrastructure Law grant

In further action, the EPA is encouraging states and communities to apply for a $1 billion Bipartisan Infrastructure Law grant.  This grant is designed to be used to address PFAS and other contaminants especially in disadvantaged communities.

Follow the links for more information on the EPAs new plan to combat PFAS or the PFAS Roadmap 2021-2024.

Delano Earlimart Irrigation District

Delano Earlimart Irrigtion District Water Recharge Projects 

BSK has been working with the Delano Earlimart Irrigation District to develop their groundwater recharge projects totaling more than 300 acres of recharge facilities.  The groundwater recharge project is known as the Turnipseed Recharge Basin, which could receive water from either the District’s distribution system of from direct diversions from the White River.  This project will significant benefit the District in balancing their groundwater.  The recharge basins are located northwest of the intersection of Avenue 24 and Road 176 near Delano, California.  BSK has worked with the District Engineer, Provost and Pritchard, on this project for the last four years and we are continuing to work on this project.

Recharge Fresno Project 

Recharge Fresno Project 

This is one of the largest public work projects City of Fresno has ever constructed with construction cost over $400 million dollars. BSK was involved in these projects for over 7 years, from design to construction.

Recharge Fresno Project Phases

The projects consisted of the Friant-Kern Canal Pipeline, a 4.5 mile long, 60-inch diameter water pipeline, which conveys surface water from the Friant-Kern Canal to the existing Northeast Surface Water Treatment Facility.

The second phase was the Kings River Pipeline where the pipeline is a 13-mile long, 72-inch diameter water pipeline. This section conveys surface water from the Kings River to the new Southeast Surface Water Treatment Facility.

The third phase was the Southeast Surface Water Treatment Facility. This facility treats over 54 million gallons per day of drinking water.

The fourth project was the Regional Transmissions Mains where the pipeline is a 13 miles 20-inch to 66-inch diameter pipe that conveys treated drinking water from the new Southeast Surface Water Treatment Facility to the existing smaller diameter mains.

The last project is the Recycled Water Transmissions Mains where the pipeline is a 20 miles pipeline that conveys recycled water from the Fresno-Clovis Regional Water Reclamation Facility into the City of Fresno for irrigation use and groundwater recharge.
