KNOXVILLE (WATE) - Knoxville city officials say demolition of the remaining McClung warehouse building is set to begin in two to four days.

At a press conference Thursday afternoon, officials say complete cleanup and removal should take four to five weeks at a cost of $127,000. A contractor will be on site Thursday night to assess the property.

A report was released Thursday by structural engineering firm National Resource Management, with the conclusion that the remaining McClung warehouse building is at risk of a "cascading structural failure."

A massive fire broke out early Saturday, which burned through one of the buildings of the historic property on the corner of Broadway and Jackson Avenue. The Knoxville Fire Department demolished that building and the remaining one is set for demolition, though a timeline is unclear.

The report says the roof beams in building four are near collapse and adds: "If a cascading structural failure were to occur, it could destabilize the walls and possibly cause a complete building collapse."

The firm conducted a structural evaluation Tuesday from the Jackson Avenue level and from a Knoxville Fire Department ladder truck.

While building four was seem to be still fully standing, there were signs of extensive damage to the roof, with several areas where the roof was open and charred. Significant failure of roof beams was noted in those areas.

The report recommends demolishing what remains of building five and all of building four. It also recommends not reopening Jackson Avenue for public access or allowing people to return to the businesses and homes on the south side of the street until the building is demolished or stabilized.

The report was released the same day that an unmanned aerial vehicle (UAV) was used to survey the damage on the remaining building.

Rick Haney fondly recalledchildhood memories Wednesday of life in Manor Homesin the early 1950s when the Rock Island housing project wasnew.

One of two sons of Korean War veteran John "J.W." Haney and his wife, Betty, he said the family was among the early residents of barracks-style housing complex, living there for about three years while his father worked at the Rock Island Arsenal.

"But time moves on," he said just minutes before an excavator tore with ease through the roof and sidewall of one of Manor Homes' buildings.

The Rock Island Housing Authority complex, located on more than four acres at9th Street and 26th Avenue, is being demolished to make way for a new Lynden Lane housing subdivision being built by the housing agency. As part ofthe authority's2008/2009 Asset Management Plan, it was determined that the property needed to be replaced because of its declining condition.

"It's so weird to watch this; you work so hard to keep these buildings up,"authority executive director Susan Anderson said as she watched crews begin what will be a four-week demolition process. "But you've got to see it go to get to the new one."

The complex, built in 1952, was at capacity with 102 families 346 individuals when the demolition was announced in April 2012, said Gail Brooks, the authority's public relations coordinator.

"The relocation was complete the 1st of November with 24 homeowners coming out of this. That was awesome," she said, adding that 53 people were moved out of subsidized housing. The vast majority of Manor Homes residents were refugees from Myanmar (formerly Burma), and most of them became homeowners.

Anderson said the Lynden Lane neighborhood will have 55single-family and townhomes as well as new streets and infrastructure, including water, sewer, gas and electric lines. "It will be a whole new layout," she added.

While the majority of the rental homes will be built at 2601 7th St., two additional four-bedroom homes will be constructed on parcels about 1.5 miles northeast of the Manor Homes site. The new homes will be one- and two-story wood-frame homes, similar to the single-family starter homes and duplexes in the area.

Morrissey Construction Co. of Godfrey, Ill., is in charge of demolition and construction of the new development, which is expected to take two years.

A five-bill package intended to strengthen the city's regulation of demolition practices, impose more requirements on contractors and demand closer supervision by city inspectors won unanimous passage in City Council Thursday.

Many of the changes such as requiring safety plans as part of an application for any demolition permit - have already been implemented by the Nutter administration, spurred by the building collapse last June that killed six people at 22nd and Market streets.

Other elements of the legislation include:

Experience requirements and safety training for all demolition contractors, with enhanced background checks on their work history and finances.

A requirement that all demolition workers complete a 10-hour safety course developed for the U.S. Occupational Safety and Health Administration.

Mandatory site inspections by the city's Department of Licenses and Inspection.

Mandatory safety training for city inspectors and their supervisors, and a requirement that contractors hire independent safety monitors for their work sites.

"All of these things will come together, along with some money in the budget, that will help us be a little safer," said Curtis Jones Jr., chairman of the Council committee that developed the legislation.

Soon-to-be dad Brian d'Arcy uploaded a gif of the starry, fiber optic ceiling in his unborn son's nursery to Reddit.

On January 30, Brian dArcy of Philadelphia posted an animated GIF of his latest project to Reddit(see above), saying, My wife and I are expecting our first son in June so I decided to install a fiber-optic star ceiling in the nursery I am building! Fellow Redditors' prodding for how-to shots led Brian to create the subsequent Imgur album,My Sons Star Ceiling, which has garnered some 300,000 views in a week.

After finding out that a baby was on the way, Brian remembered seeing the concept of a starry ceiling somewhere, but couldn't recall where. In researching the possibilities, he quickly found pictures and how-to videos online.

While a project like this may seem daunting to most of us, 27-year-old Brian also happens to be an engineering student. Armed with a $400 kit from Wiedamark, he told TODAY that the 40-hour installation was more tiresome than difficult. Being by myself, the install was very tedious, said Brian.

I would have to drill 10-20 holes in the room, climb up in to the attic, pull the same amount of fiber strands from the bundle, crawl over to the holes without putting my foot through the ceiling, and fish each strand through the holes, Brian explained. Every single strand had to be glued in place after they were installed to secure them. There are 600 strands, so even if I did 20 every time, that's 30 trips to the attic.

Well, the epic DIY project has paid off, as mom-to-be thinks the space is amazing, according to Brian. I'm not always the best at verbally expressing how excited I am that we are expecting, so this was kind of my way to show her, he added.

Soon-to-be dad's starry DIY nursery project goes viral

High Wycombe, UK (PRWEB UK) 6 February 2014

The second-floor laboratory in Christchurch House regularly accommodates up to seventy students at the same time, carrying out practical scientific experiments. With Bunsen burners and fume cupboards being used throughout the day, and seventy people, each student generating 100 Watts of heat gain combined with substantial levels of carbon dioxide (CO2), there were on-going problems with the 100 square metre space due to poor indoor air quality. Whilst the laboratory was fitted with windows, its second-floor location meant that restrictors were fitted; so the limited amount of fresh air entering the space was not enough to reach all areas of the deep-plan space.

The Universitys Estates Department decided it was time to address the problem and the Henderson Green mechanical/electrical engineering consultancy based in Southampton, which supplies design services to Bournemouth University on a range of projects, was briefed to improve environmental conditions within the space.

Henderson Green managing director Russell Pitman says first thoughts involved traditional approaches such as AC units or a roof-mounted air handling unit pumping fresh air into the laboratory.

But having discussed options with the Universitys Environment & Energy Team it was decided to investigate alternatives that would also provide a low carbon solution.

Commenting for the University, the Estates Departments Energy Officer (Technical) Dave Archer says that during the initial search he came across a Cool-phase article in a HVAC journal and decided to add the new system to the list.

The Cool-phase system, which reduces the running costs of buildings and creates a fresh and healthy indoor environment without compressors or hazardous coolants, can maintain temperatures within the comfort zone, while radically reducing energy consumption by up to 90% compared to conventional cooling systems.

Henderson Green was then asked to undertake a feasibility study to establish whether Cool-phase could handle the two key objectives the fresh air requirements and the cooling load; and Monodraught was asked to design the system and provide calculations to confirm it could achieve the required flow rates, etc.

Says Russell: We reviewed, and eventually tested, Monodraughts Cool-phase system against the air handling option and found that from the energy-saving viewpoint Cool-phase won hands-down, with relatively little increase in cost. Encouraged, we then went into a more detailed phase with Monodraught to ensure that the initial calculations matched the requirements of the space in everyday operational conditions.

Once the air quality calculations and financial appraisals were completed and the University was satisfied that the system would do the job, Cool-phase was given the green light and two systems were installed in the laboratory by Monodraught, as part of a turnkey contract with one of the Universitys approved building contractors.
