Skagway, Alaska to Whitehorse, Yukon Territory, Canada
Completed 1900
It is no disparagement to other mountain railroads to say that the construction of the White Pass. Yukon is among the most brilliant feats of railroad engineering, in view of the tremendous difficulties to be encountered and the shortness of time in which the work was done.
- Victoria Colonist, British Columbia, 1990
Combining British financing, American engineering, and Canadian contracting, the White Pass and Yukon was the first major civil engineering project on the continent above the 60th degree of northern latitude. Completed in 27 months using only hand tools, black powder, and regional timber, the White Pass and Yukon rises almost 2,900 feet from sea level at the port of Skagway to the White Pass summit on the U.S.-Canada border in just 20 miles, accomplishing one of the steepest climbs of any railroad in the world.
Built for approximately $10 million to promote the Klondike Gold Rush around the turn of the century, the 110-mile narrow-gauge railway remained an important part of the mining industry - transporting gold, silver, copper and lead ore from Canadian mines across the coastal mountain range to Alaskan ports - until it was closed during a period of low metal prices in 1982. The railway found new life six years later as a thriving excursion line serving the cruise-ship industry.
Facts
- The White Pass and Yukon follows a path originally laid out by George Brackett, a former construction engineer on the Northern Pacific Railroad who built a 12-mile toll road into the mountains in 1897. Brackett's right-of-way was purchased in 1898 by the White Pass and Yukon for $60,000.
- At the height of its operations, the White Pass and Yukon also ran passenger and freight docks at the port of Skagway, a fleet of Yukon River steamboats, a passenger-bus service north of Whitehorse, a frontier airline, and several hotels.
During World War II, the railway played an essential role in transporting laborers and materials to build the 1,520-mile-long Alaska Highway, considered an essential transportation link for troops and equipment to Alaska and northwest Canada during World War II.

Adjacent to Victoria Falls, border of Zimbabwe and Zambia
Completed 1905
Build the bridge across the Zambezi where the trains as they pass will catch the spray from the Falls.
- Cecil Rhodes, former governor of Rhodesia (today the countries of Zambia and Zimbabwe), as quoted in The Great Zambezi Bridge by Chief Engineer G.A. Hobson (1922)
In 1904, workers for South African Railways had laid more than 1,600 miles of track on the "Cape to Cairo" route proposed by British administrator and financier Cecil Rhodes - who hoped one day to run tracks the length of the African continent, from Cape Town, South Africa, to Cairo, Egypt. When the railway builders reached majestic Victoria Falls, they began construction in one of the most beautiful parts of the world. Set in a remote section of the African rain forest, Victoria Falls stretches nearly a mile across the Zambezi River, which forms the border between Zimbabwe and Zambia, before dropping more than 400 feet into a deep gorge.

Set in a remote section of the African rain forest, Victoria Falls stretches nearly a mile across the Zambezi River, which forms the border between Zimbabwe and Zambia, before dropping more than 400 feet into a deep gorge.
The Victoria Falls Bridge - built just downstream from the falls and supported by a parabolic arch spanning 500 feet - was fashioned from materials shipped on the rail line and transported across the gorge by cableway. Completed in just 14 months, the Victoria Falls Bridge opened Zambia's copper fields in particular, and central Africa in general, to modern-day transportation and commerce.
Facts
- British explorer David Livingstone first came upon the falls of the Zambezi River in 1855 and named them for Queen Victoria. The billowing mist and echoing roar of the falls -- which, during the rainy season, can be seen and heard as far away as 25 miles -- were known by the Kololo natives in the region as "Mosi-oa-Tunya," or "The Smoke that Thunders."
- Owned originally by Rhodesia Railways, Victoria Falls Bridge is now jointly owned by the national railways of Zambia and Zimbabwe. Formerly known as Northern Rhodesia, Zambia has been an independent republic of the British Commonwealth since 1964. Southern Rhodesia became known as Zimbabwe after adopting majority rule in 1979.
- Victoria Falls Bridge measures 650 feet in total length and stands 400 feet above the river, nearly 3,000 feet above sea level. Construction was accomplished by building anchored cantilevers from the edges of the gorge toward the center.
- Built to carry two railway lines, the bridge was reconfigured in 1929, when the deck by was widened by 13 feet and raised by nearly five feet, to accommodate a single rail line, two automobile lanes, and two pedestrian sidewalks.
- In the years after Southern Rhodesia declared independence in 1970, negotiations to urge the creation of a majority-ruled government took place in a railroad car parked on Victoria Falls Bridge. This spot was chosen because it was equally accessible from the borders of both Southern Rhodesia and Zambia.
- Victoria Falls Bridge has been cited for its elegance of design and responsiveness to a natural setting as well as its practical application. According to the International Section of the American Society of Civil Engineering, the bridge "embodies the best abilities of the engineer to enhance the beauty of nature rather than detract from it."

Although the branch-proper of the Wye Valley Railway (WVR) began at Wye Valley Junction, I include the following photos of the railway around Chepstow for posterity, for naturally trains ran into or through Chepstow to terminate. Seen from Beachley Lane overbridge (ST540941), view SW from England into Wales, Gloucestershire into Monmouthshire, of the South Wales Main Line, and the A48 bypass bridge which, I believe, opened in 1987. Previously all traffic went via Tutshill and over the old 1816 bridge into Chepstow. The rail bridge to the left is the 1962 remodelling of Brunel's famous (if rather ugly) 1852 tubular suspension bridge, a design he adapted for the Royal Albert Bridge at Saltash. The piers are the original. Apparently, the bed of the road bridge is one continuous slab of concrete!

464-466 Collins Street, Melbourne CBD, site of the Collins House project.
Soon to be a 195-metre high tower, 12 metres wide, of more than 260 apartments over 57 (60) floors.
Completion date given is 2018.
Fun for the engineers.
They did well with the construction by Equiset in 2012 of the ultra-thin Phoenix building - the Blue Squiggle building (my term) - at 82 Flinders Street, just 6.7 metres wide, about 24 metres deep and 130 metres high, regarded at the time as being "on the edge of structural stability", to quote Walking Melbourne.
The view here is from St James Lane to the original Collins Street façade, which is to be retained, and enhanced.
The opening is to be filled with concrete precast segments with use of the blue gantry crane. The other side (North Side) of the bridge is completed. The deck that I was standing on is pretty much completed too, the middle was still empty! Installation of precast segments would take 3 weeks to 2 months each!

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.
Goodwyn, Mills and Cawood (GMC) provided master planning, architecture, interior design, civil engineering, construction materials testing, and environmental engineering services for this project.

Trenholm State Community College is currently in the process of architecturally re-branding their Patterson Campus. Trenholm State Community College’s Automotive Collision Repair Program was moved from the Trenholm Campus to the Patterson Campus, and in doing so, will utilize an existing 18,727sf metal building/warehouse which was conducive for the collision repair area. Additional square footage was added to the building to encompass two classrooms, a resource room, offices, tool storage, and a paint shop. The paint shop consists of two new pre-fabricated paint booths, mixing station, and prep area A new façade was developed to enhance the overall appearance of the building. This building is the first of many to feature the new architectural style.
Trenholm State Community College’s Administration and Financial Aid Building project included a new metal retrofit roof and the renovation of an existing building that houses administration offices, financial aid and other student amenities as part of there “Student Success” center to allow for additional classrooms. The existing spaces were updated with new finishes and associated energy efficient mechanical, electrical, and plumbing work. A new entrance and sitework were designed to give a good first impression to students and administrators entering campus.
Trenholm State Community College purchased state of the art prefabricated welding booths for their welding program. However, the buildings electrical system could not accommodate the loads for the booths. Goodwyn, Mills and Cawood was hired to prepare the architecture and engineering drawings to allow the program to use their new welding stations.
Building B & Building D were renovations that include interior and exterior work, re-roofing, structural, mechanical, electrical, civil, site work, exterior lighting, new streets, repairs and alterations to existing streets and parking lots, landscaping, and sidewalks.

Marble plaque to commemorate the completion of the Happy Valley Waterworks (H.V.W.W.) consisting of the construction of the Clarendon Weir, Clarendon Weir to Happy Valley Pipeline and Happy Valley Reservoir in 1896. HV Reservoir was constructed by building a dam across the Field River and the Clarendon Weir by building a weir across the Onkaparinga River. The CW to HV Pipeline project includes an underground inlet tunnel 5 km in length and 3 m in diameter through the westernmost range of the Southern Mount Lofty Ranges. This tunnel is considered a 'milestone in constructional challenges and advancement' by Heritage Australia.
The HV Reservoir was constructed on the site of a small rural town, Happy Valley, which was rebuilt some 4 km east of its original location. The cemetery and school were also relocated. Since 1962, the HV Reservoir has also been serviced by the Myponga to Happy Valley pipeline.
Mount Bold Reservoir, SA's largest reservoir, was built on the Onkaparinga River upstream of the Clarendon Weir in 1937. In 1973 the Murray Bridge to Onkaparinga River Pipeline was completed to transport water from the River Murray to the Onkaparinga.
Today, except for a small trickle, the entire water capacity of the Onkaparinga River is diverted to the HV Reservoir, placing severe stress on the fish habitat and ecosystem downstream including in the Onkaparinga River National Park through high levels of salinity and siltation.
The inscription on the plaque reads:
H. V. W. W.
1896
Carter Gummow & Co.
Contractors
Hon. J. G. Jenkins
Commissioner of Waterworks
The plaque's preservation is probably due to its well hidden location behind high SA Water fine-mesh fencing where the pipeline enters the underground tunnel. (The plaque is on a slope and I had to balance on the edge of the fencing which is too fine to grip, so frame, climb, balance, click, jump for each attempt... My assistant thought I was very silly ;-)
Carter Gummow & Co. was founded by Frank Moorhouse Gummow and participated in the following water engineering projects:
Annandale Sewer Aqueducts over Johnston's Creek and White's Creek, Annandale, Sydney NSW, 1896
Morell Bridge over the Yarra River in South Yarra, Melbourne VIC, 1899
North Richmond Bridge over the Hawkesbury River at North Richmond, NSW, 1905
