Celebrating our Miraculous Medal tradition in Chula Vista, California, where we've just placed medals in the first concrete pour along the I-805 Widening Project; pouring for soundwall CIDH piles. Walsh Construction's work on the Caltrans State Highway widening project includes retaining walls, soundwalls, bridge widening, landscape and electrical.

Designing a mountain road isn't for the faint of heart. It's great to see my friend and colleague, Tammy Heffron, explain what it takes! Check out this new video from the Wall Street Journal that delves into why these roads are so complex and difficult to design. https://lnkd.in/g55JXrPn

Bridges can be classified into various types based on several factors, including their structure, purpose, and the materials used in construction.
1. Beam Bridge: The simplest type of bridge, consisting of a horizontal beam supported at each end.
Example: Carrying Place Bridge in Ontario, Canada.
2. Arch Bridge: a curved structure that distributes weight evenly.
Example: Sydney Harbour Bridge in Australia.
3. Suspension Bridge: Towers and cables suspend the roadway deck.
Example: the Golden Gate Bridge in San Francisco, USA.
4. Cable-Stayed Bridge: Cables support the deck, attached directly to towers.
Example: Sunshine Skyway Bridge in Florida, USA.
5. Cantilever Bridge: horizontal beams supported at one end.
Example: Forth Bridge in Scotland.
6. Truss Bridge: Framework of connected elements (trusses) supporting the deck.
Example: Iron Bridge in Shropshire, England.
7. Tied Arch Bridge: an arch structure with tensioned cables connecting the ends of the arch to the bridge deck.
Example: the Natchez-Vidalia Bridge in Louisiana, USA.
8. Floating Bridge: supported by pontoons or floats, keeping the deck afloat on water bodies.
Example: the Homer M. Hadley Memorial Bridge in Washington, USA.
These are just a few examples, and many variations and combinations of bridge types are used in engineering to suit different environments, spans, and loads.
Thanks for sharing a great article promoting the importance of corporate memory and how this can be achieved in the digital age through data hosting and sharing platforms such as IAMS. Murphy Geospatial have supported Irish Rail throughout their journey to developing a systematic risk-based bridge scour inspection programme.
Murphy Geospatial surveyors were on site the day after the bridge collapse to survey the extent of the damage using bathymetric survey either side of the bridge, and laser scanning technology that was emerging at the time. We also installed a digital monitoring system with bespoke tilt sensors to ensure the remaining spans were not also showing signs of unexpected movement. We assisted with setting out, and monitoring during the reconstruction phase in the months after the collapse.
Since then, we have undertaken 2000 bridge scour inspections as part of the Level 1 Assessment approach for bridges on 1-, 3- and 6-year inspection cycles. Our surveys have been key to identifying scour defects, monitoring any known scour defects, and enabling decisions for design of bridge scour countermeasures.
We look forward to continuing to assist Iarnród Éireann Irish Rail in their digital transformation and the management of risk around their critical infrastructure assets.

At about 6.22pm on August 21, 2009, Pier 4 of the Malahide viaduct, along with the post-tensioned concrete beams of spans 4 and 5, collapsed into the Broadmeadow estuary, about 13km north of Dublin, just after an Iarnród Éireann (IÉ) train travelled across it.
Despite the relief that nobody was injured due to the collapse, the immediate challenges for IÉ were immense as the company, in parallel with repairing the physical damage to the viaduct, grappled with questions such as “What about all our other assets?”; “How can we reassure our stakeholders that our assets are safe and fit for purpose?”; “How can we ensure that this kind of event does not happen again?”.

One of the finer points of the Dutch blueprint is the splayed, mountable, modular curb laid between the (continuous) foot and cycle path.
Here it is exported to Stretford in Manchester; where a four-lane traffic sewer is being reimagined as a more attractive and inclusive space.
The Golden Gate Bridge stands as a testament to human ingenuity and engineering achievements. Completed in 1937, the iconic suspension bridge spans 1.7 miles across the Golden Gate Strait, connecting San Francisco to Marin County. The bridge was designed to withstand strong winds, ocean currents, and earthquakes, making it a remarkable feat of engineering. The project was led by chief engineer Joseph Strauss and his team, who employed innovative techniques and engineering marvels of the time.
Here are some key aspects of the bridge's amazing construction:
1. Design: The bridge was designed as a suspension bridge, with two main towers and a main span suspended by steel cables.
2. Materials: The bridge's main structure is made of steel, with over 83,000 tons of it used in its construction.
3. Safety Measures: Given the challenging environmental conditions, safety was a top priority during construction. Workers were equipped with safety nets, which saved the lives of 19 individuals who fell during construction.
4. Construction Techniques: Engineers used a combination of traditional and innovative construction techniques, including floating derricks to assemble the towers and a unique movable scaffolding system to paint the bridge.
5. Paint Color: The iconic orange-red color of the bridge, known as "International Orange," was chosen to enhance visibility in foggy conditions and to complement the natural surroundings.
6. Completion Time: Despite the challenges posed by the treacherous waters and strong winds, the construction of the Golden Gate Bridge was completed in just over four years, which was considered an impressive feat at the time.
The Golden Gate Bridge remains an architectural marvel and a symbol of San Francisco's identity, continuing to attract millions of visitors each year.

💡 Project Spotlight 💡
One of our specialties as a structural engineering firm is structural insulated panels (SIPs).
SIPs were used for unmatched energy efficiency and strength against coastal elements for this particular beachfront property in Pass Christian, Mississippi.
We designed the structure to withstand hurricane-force winds and create a fortified home.
We partnered with Extreme Panel Technologies, Collaborative Design Group, inc. & and others on this!
