Engineers give Puerto Rico infrastructure a grade of ‘D-‘

By on November 14, 2019

Energy received the lowest grade of ‘F’

SAN JUAN — The American Society of Civil Engineers (ASCE) issues an Infrastructure Report Card every four years. After a comprehensive assessment of infrastructure conditions and needs, it assigns grades using a simple A to F school report card format and makes recommendations to raise them.

The ASCE Committee on America’s Infrastructure, made up of expert civil engineers, assigns grades using the following criteria: capacity, condition, funding, future need, operation and maintenance, public safety, resilience and innovation.

In its inaugural Report Card for Puerto Rico’s Infrastructure, the ASCE Puerto Rico Section announced a near failing grade of a ‘D-‘ for the island’s infrastructure. The Report Card graded eight categories of infrastructure: bridges (D+), dams (D+), drinking water (D), energy (F), ports (D), roads (D-), solid waste (D-), and wastewater (D+).

According to the report, much of the island’s infrastructure is reaching the end of its useful life, and infrastructure networks are still being rebuilt after hurricanes Irma and Maria devastated the island in 2017. Energy received the lowest grade of ‘F,’ meaning the system’s infrastructure is in unacceptable condition and has widespread advanced signs of deterioration.

“Hurricanes Irma and Maria destroyed much of Puerto Rico’s electric grid in 2017, causing the island to experience the longest blackout in American history and the second-longest blackout across the world; some areas on the island had no electricity until 11 months after the storm. In August of 2017, Puerto Rican officials estimated that $1.6 billion was needed in overall infrastructure investment to meet the economic goals needed to prevent bankruptcy,” reads an article published on, where the the full report can be found here.

Hurricane Maria’s impact one month later increased the funding required to improve infrastructure. The Puerto Rico Electric Power Authority (Prepa) proposed a $20 billion plan to renovate the energy grid on the island. Thus far, funding has been provided to restore electricity access, but the resulting grid is fragile, and blackouts are frequent, the ASCE adds.

However, the society says, “Puerto Rico’s failed energy infrastructure did not start with the 2017 hurricanes; the existing grid was already in disrepair and experienced frequent outages. Coupled with the 2017 events, the electric grid reached the point of total failure. Puerto Rican authorities have since focused their efforts on short-term goals of restoring power as quickly as possible.”

Congress appropriated $42.5 billion to FEMA for recovery efforts, but Puerto Rico only received $15 billion as of May.

“Puerto Rico is limited in what it can do financially to rebuild and revitalize the island’s infrastructure because the island is structured under tier 2 of the Puerto Rico Oversight Financial Oversight and Management Board (Promesa), which has fiscal control over the island due to the island’s bankruptcy proceedings,” as the ASCE wrote.

“If the island wants to rebuild and modernize its infrastructure, it must increase received investment by $1.23 billion to $2.3 billion annually—or $13 to $23 billion over 10 years. However, when considering deferred maintenance and hurricane-related recovery projects, the investment gap is even larger. There is a dire need for the island to rebuild smarter by building to adequate codes and standards, acquiring funding from all levels of government, and incorporating resilience into infrastructure plans by using climate-resilient materials,” the society summarizes about the report.

While most of the island’s infrastructure systems are in poor condition—exhibiting significant deterioration, the report describes opportunities to rebuild its infrastructure with a focus on resilience.

The following are recommendations by the ASCE Puerto Rico Section:

  • Increase the resiliency of Puerto Rico’s infrastructure. Our future depends on the ability of our infrastructure to not only protect us against increasingly severe storms, but to facilitate timely emergency management, response, and recovery efforts after a major event. The resiliency of all our networks can be improved by requiring the Central Government, municipalities, and industry build to ASCE standards, incorporating life-cycle cost analysis into projects, and by maintaining our existing assets.
  • Establish a Puerto Rico Infrastructure Plan with a wide variety of stakeholders and experts in the field. Infrastructure development is a long-term endeavor with significant impacts on economic growth and competitiveness.
  • Puerto Rico’s infrastructure systems need comprehensive and consistent maintenance programs and databases. A lack of programmed funding for the comprehensive maintenance of our existing roads, bridges, energy, dams and other critical networks has severely impacted the lifespan of these assets. Developing comprehensive asset management databases is a critical first step, as these databases can help determine total funding and maintenance needs.
  • Improve and increase the technical expertise at agencies that own and operate infrastructure so that they can complete regulatory requirements. Many of Puerto Rico’s agencies have too few technical experts to operate the infrastructure in accordance with regulations and customer expectations. Additionally, institutional knowledge is not codified in the agency, but instead may be lost when individuals retire or resign.

To facilitate smart building, ASCE published a series of codes and standards for grid design and construction, such as ASCE 7, to better enable Puerto Rico’s energy infrastructure to withstand future storms and other stresses.

ASCE State Infrastructure Report Cards are modeled after the national Infrastructure Report Card, which gave America’s infrastructure a grade of ‘D+’ in 2017. To read the full report and learn more about Puerto Rico’s solutions to raise the grade, click here.

The ASCE represents more than 150,000 civil engineers worldwide and is the United States’ oldest national engineering society. It works to raise awareness of the need to maintain and modernize infrastructure using sustainable and resilient practices, advocates for increasing and optimizing investment in infrastructure, and improve engineering knowledge and competency.
