In a special summer UrbanPlan Scholars program, four teams presented their proposals for a six-acre parcel next to UH West Oahu. They had to address zoning requirements, affordable housing/workforce housing, rail/transit issues, agriculture, and energy.
UrbanPlan is a global competition run by the international Urban Land Institute. Hawaii schools have taken top honors in the global competition two years in a row, including Iolani School last month, and Iolani and Kalani two years ago.
Teams were made up of local high school students from Iolani, Kalani, LeJardin, MidPac, Punahou, and St. Andrews.
They conducted outreach to stakeholders and residents in West Oahu and found affordable housing to be the number one community need.
Ideas ranged from rooftop greenhouses and beekeeping to fully solar-powered facilities to integrating UHWO student and campus life.
Judges included Bob Harrison (FHB), Duff Janus (ASB), Brennon Morioka (UH), Mike Gabbard (Senate), Jim Houchens (Mitre), and Alana Kobayashi.
Bernice Glenn Bowers helped them plan for future high-tech industry in the area, doubled the size of the cash prize to $1,500.
One of the stranger things about Haven SeaChallenger is that this substantial offshore construction platform is more than half a century old. It was built in Japan by Nippon Steel Corporation in 1974, yet after rebuilding and modernisation it is still earning its keep on some of Britain’s newest and largest infrastructure projects. It has previously carried the names Fugro 1200, Eunsung 1200 and Tsukudo No. 1.
Seen here off Sizewell on the Suffolk coast in August 2026, the vessel is a self-elevating jack-up barge. It floats to its working position like a conventional barge, then lowers its four huge tubular steel legs onto the seabed. The hull can then be jacked upwards, leaving the working deck effectively standing on stilts above the waves. This creates a remarkably stable platform from which heavy cranes, piling machinery and other equipment can work without the vessel rising and falling with the sea.
Haven SeaChallenger measures approximately 50 metres long by 24 metres wide, giving it about 1,200 square metres of deck area. Its four legs are around 55 metres long and 1.8 metres in diameter, while its deck is rated for loads of up to 1,000 tonnes. The legs can be raised or lowered at roughly 30 metres per hour. Despite the rather industrial appearance, it can also provide live-aboard accommodation for crews, allowing offshore work to continue without repeatedly ferrying personnel to and from shore.
The vessel is operated by Red7Marine, the Essex/Suffolk-based specialist marine contractor. The registered owner has been listed as I&C Ltd, trading as Red7Marine. Red7Marine bought the vessel in 2021 as a major expansion of its jack-up fleet, specifically to enable it to undertake larger marine infrastructure, renewable-energy, nuclear, port, coastal-protection and flood-defence projects. The purchase price does not appear to have been publicly disclosed.
This is not simply a floating crane platform. Jack-up barges such as SeaChallenger are useful wherever construction has to take place in shallow or near-shore water. Piles can be driven, sea defences installed, cables landed, foundations built and underwater structures positioned while the barge itself remains almost completely isolated from wave movement. Red7Marine even has specialist piling gates designed specifically for SeaChallenger, including a structure more than 15 metres high used to hold piles accurately while they are installed.
The wider setting in the first photograph is particularly interesting. Behind SeaChallenger stands the unmistakable white dome of the existing Sizewell B nuclear power station, while the enormous construction site for Sizewell C is spreading along the coast immediately beside it.
Sizewell C is being built as a two-reactor 3.2 GW European Pressurised Reactor – EPR – nuclear power station, intended eventually to produce enough electricity for the equivalent of around six million homes. The government gave the project its final investment decision in July 2025 and financial close followed in November that year.
Its scale is extraordinary. The National Audit Office reported in May 2026 that Sizewell C Ltd's current risk-adjusted project baseline was around £38.2 billion in 2024–25 prices, with the station projected to be fully operational by July 2039. A higher regulatory threshold allows for costs of up to approximately £47.7 billion, associated with a later August 2043 completion scenario.
Much of the work taking place offshore is intended to make construction of the power station itself possible. Between about 2025 and 2035, Sizewell C's marine programme includes temporary sea defences, cooling-water intake and outfall structures beneath the seabed, drainage and desalination works, a permanent Beach Landing Facility and a temporary Marine Bulk Import Facility, or MBIF.
The MBIF is essentially a temporary freight jetty extending roughly 500 metres into the North Sea. Large barges will be able to berth alongside it and unload aggregate and other bulk materials directly onto the Sizewell construction site. Around 2.8 million tonnes of material are expected to pass through the facility during construction. Its purpose is to avoid sending all of that material along Suffolk's roads. Sizewell C intends a large proportion of its construction material to arrive by either rail or sea.
SeaChallenger is therefore part of a much wider offshore construction fleet. Other jack-up barges, including Excalibur and NP497, have been working within the Sizewell marine construction zone on piling, drainage, desalination and other offshore structures during 2026. At the peak of marine construction later in the decade, Sizewell C Harbour Authority expects the waters off the site to become exceptionally busy with construction vessels, barges, tugs, survey craft and service boats.
SeaChallenger itself has already had an unusually varied working life. In 2023 it was used to transport an offshore artificial “kittiwake hotel” from Lowestoft, providing nesting space for black-legged kittiwakes displaced by offshore development. In 2024 it was photographed off Weybourne on the north Norfolk coast during offshore cable-related work. It has also been used on projects such as Portland Port's new deep-water berth, where Red7Marine installed 136 steel tubular piles as part of a £3.6 million piling contract.
So although its basic hull dates from 1974, Haven SeaChallenger is now working in a world its original designers could scarcely have imagined: offshore wind farms, environmental mitigation projects and the construction of a new generation of nuclear power stations.
These aerial photographs show particularly clearly how a jack-up barge works. What appear at first to be four giant chimneys are actually its legs. When work is complete at one location the hull is lowered back into the water, the legs are retracted, and the whole platform can be towed away to its next job.
The result is a rather extraordinary combination: a 52-year-old Japanese-built marine platform helping construct one of Britain's most modern and expensive energy projects.
A mini-series following my 44mm-high Homies character Pelon, where he poses for photo ops at potholes on the streets of Mount Tabor Park.
Leadership fixes potholes, not patching.
Chronic neglect of Portland’s streets is manifesting in the burgeoning number and size of dangerously large potholes across the city. Here, pothole road damage is seen in Mount Tabor Park, Portland, Oregon.
Engineering: From a technical perspective, a great deal of information can be gleaned from a deep pothole, as it provides a cross-section-view of the pavement structural section…or lack thereof, as in this case. Here, the asphalt wearing surface is heavily pitted, highly oxidized and brittle, confirming many years of neglect. The asphalt layer is minimal, confirming this road never received the maintenance originally planned. The river-rounded pebbles of the base course layer tell the story of a roadway constructed originally from deficient materials. Roadway base course should be well-graded, faceted aggregate so as to provide optimum particle interlock – a crushed and sieved mix from those same pebbles would suffice. Finally, from the moisture visible in the pothole, and the shape of terrain at the road shoulders, it is clear that poor drainage has contributed to the failure of this road. The conclusion is unequivocal; this road has failed and no amount of patching will restore a level of service – or service life – that should be reasonably expected of it.

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.
Norris, Tennessee
Completed 1936
Norris Dam impounds the Clinch River, a mountain tributary of the Tennessee River. The facility stands as a tribute and symbol of the birth of the Tennessee Valley Authority (TVA). Given broad jurisdiction over resource development in the watershed (a 40,000-square-mile basin comprising parts of Virginia, North Carolina, Georgia, Alabama, Mississippi, Kentucky, and Tennessee), the TVA was formed to plan for flood control, improve navigation, and produce hydroelectric power.
As the first completed project of the Tennessee Valley Authority, Norris Dam launched one of America's great political experiments. It provided the model for many of the TVA's policies and procedures, which would aid in the success of the agency's many future projects.

I went for a visit to Derby for their comedy festival and to spend the weekend with Gemma.
Saturday morning we went to Belper to the river gardens and the horseshoe weir, which is an incredible piece of civil engineering!
The gardens are lovely and tranquil. It was a great little alternative to our usual trip to Dovedale - which we called off because the weather wasn't great.
Had a lovely morning though!

West Baden, Indiana
Completed 1901
The steel dome stretches 200 feet in diameter and rises 100 feet at its top. To accommodate thermal expansion, the inverted bowl-shaped structure originally rested on rollers that sat on the flat tops of six-story columns
There was a time when Americans from the Eastern seaboard braved long rail trips to southern Indiana in hopes that the water at the French Lick natural mineral springs could bring relief from alcoholism, pimples, gallstones and a host of other ailments and illnesses.
To accommodate these guests in style, Harrison Albright constructed a luxurious hotel and spa in just 277 days, whose site covered 684 acres. The building's primary feature was its central dome, considered the largest clear-span dome in the world when built. Many of the hotel's 510 rooms surround the dome and the murals, mosaic and marble of its magnificent atrium.
In the 1930s, when natural spring spas lost their appeal as potential cure-alls, the hotel's business began to wane. Once the Great Depression hit, it closed.
