Cohasset, Massachusetts
Constructed 1855-1860
Minot's Ledge is a wave-swept rock formation in a rocky area of ocean about a mile off the Cohasset shore near Boston. Numerous serious shipwrecks prompted the government to erect a beacon there, and construction began in the summer of 1847.
The light, constructed on tall iron legs, was put into operation on January 1, 1850. Designers believed that the water would flow freely through the legs, leaving the lighthouse intact. But a terrible winter storm toppled it in 1851, killing the two assistant keepers.
The replacement lighthouse, built of granite blocks between 1855 and 1860, still stands. Considerable foundation preparation along the narrow ledge of rock secures the base of the lighthouse. Interlocking granite blocks provide stability against raging Atlantic storms.
Facts
The first task in building the new lighthouse was to remove the pilings from the first lighthouse and insert a new iron framework into the remaining piling holes. The new framework was intended to anchor the stone masonry to the rock ledge. The work was done over the period April 1 through September 15, 1855. In January 1856, a violent Atlantic storm blew the New Empire into the piling, completely destroying framework.
- Over a three-year period, a circular base, 30 feet in diameter, was excavated into Minots Ledge rock. New dowels nearly 25 feet high, or as high as the 12th course of granite masonry were anchored into the rock.
- Three things were necessary, a perfectly smooth sea, a dead calm, and low spring tides. This could only occur six times during any one lunation, three at full moon and three at the change, said Captain Barton Stone Alexander. During 1855, only 130 hours of work could be performed at sea; in 1856, 157 hours; in 1857, 130 hours; and in 1858, 208 hours.
- Samples of granite from many locations were submitted and tested, but granite from Quincy was deemed to be the best. Over 3500 tons of rough Quincy granite were delivered to Cohasset.
- Captain John Cook, a master seaman and rigger, devised the model for the derrick that was used to lift the massive granite blocks onto the lighthouse.
- Each stone was hand chiseled in an interlocking dovetailed pattern so that it fit perfectly with its neighboring stones and those above and below it. A total of 1079 stones were crafted, weighing a total of over 2350 tons. The blocks for each course were fitted together on shore to assure perfect fit before being transported to the Ledge.
- It was July 1857 before the laying of stone could commence, and another year before the underwater construction work was completed. Once the stonework was above the tidal range, construction proceeded more rapidly.
- The total cost was approximately $300,000.
- Captain Barton Stone Alexander, a United States Military Academy graduate with the United States Corps of Engineers, was chosen to develop and finalize the design and oversee construction.
- The lighthouse has withstood every gale since 1860. The strongest waves cause nothing by a strong vibration. On some occasions the seas have actually swept over the top of the structure with no more damage than that caused by a few leaky windows.

The City of Hoover has seen enormous growth in its sports programs over the past 10 years and needed a new complex that would fulfill their existing needs, allow for growth and give the City the ability to create new revenue streams and take advantage of sports tourism by hosting large tournament events. Hoover had not built any new athletic facilities in 15 years. At the same time the City’s sports participation had increased by multiples of 200% - 500% depending on the sport. The growth was caused by increases in both youth and adult sports leagues, as well as the relatively recent popularity of additional sports.
The multi-purpose Finley Center, which connects to the existing Hoover Met baseball stadium with a covered walkway, is able to accommodate a full-size football or soccer field, nine regulation-size basketball courts, 12 regulation-size volleyball courts or six indoor tennis courts. It can also seat 2,400 for banquets and 5,000 for events with general seating, such as a graduation ceremony or concert. Additional features of the indoor facility include a recreational walking track suspended 14 feet in the air, an athletic training and rehab center, and a food court.
The Finley Center sits on a 120 acre site that GMC master planned and includes fields for soccer, lacrosse, football, baseball and softball, tennis courts, a play ground walking track and splash pad.

The Ferro-Concrete Review was a monthly journal produced to publicise the Mouchel-Hennebique method of reinforced concrete construction 'in engineering and architetcural practice'. Edited by W Noble Twelvetrees it is a highly informative periodical full of details and illustrations of numerous contemporary construction projects. The Mouchel-Hennebique method was the result of the engineer L G Mouchel being the British agent for the Hennebique French/Belgian method of early concrete reinforcement patented by François Hennebique (1842-1921).
This advert was taken by the Trafford Park, Manchester, based construction company of Edmund Nuttall & Co. who were the principal contractors in the construction of the famous Royal Liver Building at Pier Head in Liverpool. One of the "Three Graces", the major buildings that formed the maritime gateway to the great port city, it was designed by Walter Aubrey Thomas for the Royal Liver Assurance Company was opened in 1911 being one of the earliest exmaples of a reinforced concrete structure in the UK.

Work continues on the "Smart" section of the biggest car park in the NorthWest of England. The M6 Motorway between Junction 16, (Crewe), and Junction 17, (Sandbach), Cheshire.
We'll see how smart it is after the first major incident following the opening of the section.
Extract from online media - “When the smart motorway goes live, drivers will benefit from an extra lane in each direction and variable speed limits will be used to keep traffic moving.”
Keep traffic moving? That will make a change then.

Bayonne, New Jersey, to Staten Island, New York
Completed 1931
As an engineering achievement in two-hinged, steel-arch building, the [Bayonne] Bridge is first notable for its great length, attaining at the same time a grace of outline hardly possible with any other type of structure.
- Engineering News Record, 1928
The longest steel-arch bridge in the world for 46 years, the Bayonne Bridge continues to be celebrated today as a major aesthetic and technical achievement. The 1,675-foot bridge replaced a ferry service which until then was the only means of crossing from the Bayonne peninsula to Staten Island. While providing this essential link in the transportation network of greater New York City, the bridge's mid-span clearance of 150 feet also allows for unobstructed navigation on Newark Bay, the main shipping channel to the inland ports of Newark and Elizabeth, New Jersey.
The engineering achievements of the Bayonne Bridge include the first use of manganese steel for main structural elements, several advances in structural analysis, and an innovative system of falsework used in its construction. Its design is one of many in the New York City area representing the work of Othmar H. Ammann, whose majestic George Washington Bridge was opened less than a month earlier.
Facts
- The Bayonne Bridge has been widely recognized as an engineering work of great artistic accomplishment. The American Institute for Steel Construction awarded it a prize in 1931 for most beautiful steel-arch bridge, and The New York Times, in a later tribute, said "there is a symmetry and fineness of detail about the Bayonne Bridge that is impressive and almost haunting."
- The bridge's design is based in part on New York City's 1917 Hell Gate Bridge, on which Ommann worked as chief assistant to noted engineer Gustav Lindenthal. In its time, the Hell Gate Bridge, at 977 feet, was the longest steel-arch bridge in the world. The Bayonne Bridge surpassed it by nearly 70 percent, and remained the world's longest steel-arch bridge until the 1970 opening of the 1,700-foot New River Gorge Bridge at Fayetteville, West Virginia.
- The design of the Sydney Harbour Bridge, which opened in 1932 with a span shorter by only five feet, closely resembles that of the Bayonne Bridge. After the opening of the Bayonne Bridge, the golden shears used in its ribbon-cutting ceremony were sent to Australia for use at the opening of the Sydney Harbour Bridge, then dismantled so each country could keep one blade as an historic memento.
- Calculations of secondary stresses helped make the construction of a structure as large as the Bayonne Bridge possible. These had tended to be ignored in the design of earlier bridges and were later checked by extensometers on the actual structure. Design calculations also included compression tests on the largest columns of manganese steel ever made.
- Falsework secured on solid rock below the water was used in the Bayonne Bridge's construction to avoid the need for heavy anchorages and abutment towers in the bridge's design. The falsework towers were made of material that was later used in the bridge.
