ICF Construction with Hambro Floor System

Hambro D-500 Steel composite floor joist system is an advanced up-to-date answer to elevated floor construction challenges. Combining steel joists with poured concrete, the system consists of hybrid concrete/steel T-beams running in one direction and an integrated continuous slab in the other. The bottom chord acts as a tension member in the concreting stage and during the service life of the floor. The web system tying top and bottom chords together consists of bent rods and resists vertical shear in a conventional truss manner. The patented 13 gauge top chord acts as a compression member during the non-composite stage. In the composite stage, the top chord is embedded in the concrete and functions as a continuous shear connector. The concrete slab is reinforced with welded wire mesh. The top chord functions as a high chair, developing negative moment capacity in the concrete slab which behaves as a continuous one-way reinforced slab.

Patio Roof Construction - The ABCs

A patio without a patio roof cover leaves your house incomplete in many ways. To some it may look a stalled construction. To others it may look like inadequate utilization of what could be made part of the overall living space.

A patio, no matter how simple or complicated the design, can add to the livability of your house. It can increase not only the beauty of the house but also its property value. One of the main purpose of the patio roof is to provide protection from the elements. With the patio roof above your head you can enjoy outdoor space even in bad weather.

One the most popular roof structures are the simple patio roof. To learn how to install a patio roof can be easy. Whether the roof is attached to the house or is freestanding you will need the same basic framework. That is, posts set in concrete to provide extra stability, supporting beam and rafters. The kind of patio roof you select will determine how strong the framework would be and how far apart will the rafters be spaced.

There are many patio roof designs to select from. You can choose from a wide variety of patio roof designs such as plastic, aluminum, wood, fiberglass canvas or vinyl. If you want a roof that allows a little sunlight then go for the lightweight and easy to install plastic shades over widely spaced rafters. The roof should slope a bit to drain away the water or for snow to slip down

Wood is popular material because of its appearance and relatively low costs. However it is not resistant to erosion by the elements. It can warp or crack under too much stress. Wood is a good choice if you your patio to have a natural look. With wooden patios you can also have flowers and vines on the top or up the sides.

One of the most popular roof covers is aluminum, because it comes in a variety of designs. Aluminum comes in a variety of colors so that you can match the roof color to your house. It is affordable and longer lasting. Unlike wood, aluminum does not warp or break when exposed to the elements. The most attractive feature of aluminum is its high strength to weight ratio that will stand up to the force of the wind and weight of the snow. By following a few simple instructions you will be able to install an aluminum roof.

Fiberglass and plastic are the other preferred materials for patio roofing. Fiberglass is a translucent material that allows light and heat but keeps away rain. In fact they trap heat to create a greenhouse effect. That is why fiberglass may not be a very good choice for a west or a hot south facing patio

For stylish entertaining looks, go for a pergola. A pergola is a structure comprising only columns and an open roofed structure. The open roof is partly covered up by beams and rafters. Such a roof therefore will not protect you from rains but will provide some shade. To make your pergola still more attractive you could have growing vines or climbing flowers on the sides.

Concepts In Construction - System Building

This can also be termed as modular building. This refers to a form of building whereby a similar form of construction is adopted, usually by creating standard sizes of elements, thus remaining with the task of just creating multiples of the said modular element. The following are common elements adopted for this form of construction.

· Formwork: this refers to the mould into which concrete is poured and cured to provide the desired size and shape. Formwork can either be made of wood, steel, aluminium or PVC among other such items. In system building, a standard size of formwork is adopted, thus requiring similar sizes and forms of concrete elements in construction. This is especially easily achieve for elements like soffit formwork and beam and column formwork. Formwork props are also easily standardized to some extent where floor heights are more or less similar.

· Doors and windows: standard openings will call for standard windows, thus making it easy as well as consistent the process of their construction.

· Wall panels: For prefabricated buildings, it is usually easier to have a similar design for many units.

System building ensures similarity or near similarity of construction work, whether in small projects or big ones. This similarity leads to repetitive work, which gives the following benefits;

· Economies of scale: Due to the repetitive nature of the work at hand, there arises economies of large scale production.

· Economies in operation: due to the benefit of doing the same thing over and over again, it becomes easier to follow and even make more per unit time.

· Enhancing Quality: When something is done for a long time, people will understand it better and as such will be easier for them to achieve the desired quality of work.

System building can only be achieved in a well coordinated development scenario and where designers (architects and engineers) work hand in hand to see to this goal. Architectural associations have been working hard to absorb such technologies in their practice. It is important to seek the available opportunities and to pursue all the possible avenues in a bid to hit these goals. It is also important to ensure that all the stakeholders are well informed about system building together with all the benefits that are possible with it. Like for the case of formwork, it is important to go for durable material to ensure that the benefits of this technology due to repetitive work.

Construction: Composite attic system

Construction: Composite floor system: training video from the Corus BCSA training pack. "Composite floor slabs generally comprise profiled steel floor deck with in-situ concrete cast over the deck. The deck acts as permanent shuttering and spans in a direction transverse to the secondary beams. Primary and secondary beams in composite steel frames are rigidly connected to the floor slabs by 'shear studs', which are connected to the beams by through-deck welding techniques. This allows the floor slab and the beams beneath to act compositely. Beam depths are therefore less than any equivalent non-composite frames."

Expert Advice on Basement Construction

Basement construction is something you have to carefully plan before executing. One mistake and you could end up with problems year after year, and you really wouldn't want to have to deal with that and spend periodically for repairs. Let's take a look at some important points to make your basement dreams come to life.

Organize Ahead

The current basements may have weight rooms and saunas, home entertainment centers, lap pools and dance floors, climate-controlled wine cellars, bars, bedrooms and baths. Think about what you really want and visualize. Imagine what your empty basement will look like once you're done with it. You may then try to sketch out your concept, visit your basement, and visualize how you're going to put together your ideas.

Be Practical

Now's the time to consider the basics of basement construction. Make sure you know how to deal with the dampness, flooding, musty odors and mold. Hire an expert to establish the source of any water problems, including seasonal leakage, and ask for a solution. You may employ one or more sump pumps, with one run by a battery or generator lest a power outage. Utilize a dehumidified and employ appropriate ventilation. Moreover, consider installing other "necessities" such as water heater, furnace, wiring, heating/cooling systems, and so on. These should be highly accessible.

Get Creative

You are doing a cool basement construction project, not something that will look like every other basement out there. Don't leave your flooring as cold concrete. You could easily install wood products to warm up the place. It's as easy as tapping the floor pieces together over the concrete ground. Allow some light in by either adding windows or unique lighting fixtures. Observe other basement styles in your friend's basement and with photos online / in magazines. See what clever ideas and concepts they have. Sometimes, simply visualizing is not enough to make your dream basement a reality.

Get Started With The Appropriate Materials

Getting the right materials for your basement construction project is extremely important. First of all, materials and labor expenses are generally what establishes a project's overall cost. Don't expect to have only basic materials if you're planning on building a plush basement that nobody else in your neighborhood has. Common sense should be used here.

Get Clever

Your walls could have noticeable cracks. Consider using paint, murals, wallpaper or panels. In parts where the ceiling is lower due to plumbing, you cold employ built-in closets or features. There are many tricks to troubleshooting basement construction problems, such as employing vertical lines on the walls to create the illusion of height (for low-ceiling basements). To transform a cold basement to a warmer, more inviting one, use dimmed lights with a yellowish glow (rather than white fluorescent ones), area rugs (wall-to-wall carpets can create moisture issues), and warmer tones for wall paints and furniture fabric. Don't forget the staircase-this is the first people will actually notice. So try to match the staircase with the overall design of your basement. Think about employing a French door so that you keep noise away but can still view what's going on.

Stair Handrailing Or Guard Rail - Construction and Safety

Before the 1980s most stairways had a handrail and to this day, most stair handrails are not considered guard rails. Well things have changed and now most stairways require a guard rail and it gripable handrail.

What's the difference between a stair handrailing and a stair guard rail, quite frankly about 6 inches. Your stair guard rails have a minimum requirement of 42 inches where stair handrails built before the 1980s had a handrailing for protection with a minimum requirement of 36 inches.

This does not mean that older stair handrails that are 36 inches tall will need to be removed and replaced, because the new building codes have changed. If you were to rebuild the stair handrail or do any work on the stairway that required a building permit, they could have you change your stair handrailing to meet current building codes.

I was helping another guy frame a new house in 2005 and while I was on the job I would mention to the owner, certain concerns of mine with other parts of the job. After a while he realized, that I knew what I'll was talking about and started to pay attention when ever I mentioned anything related to home building.

He asked me if I would be interested in building the stair handrailing system and at the time I was too busy. I reminded him of the minimum requirements for the stair guard rail, it was no longer referred to as a stair handrail and would need to be at least 42 inches in height and include a gripable handrail.

Well as you guessed it, the next time I walked into the home, I noticed a 36 inch high stair handrail. I reminded him and he wasn't too concerned, because he hired someone that knew all about building stair handrails.

The building inspector made him remove and replace the stair handrail, before he would approve the home for final inspection. Don't make the same mistakes, learn a little more about stair handrail safety and don't become another statistic in the home building industry.

Always check with your local building department, whether you're reading articles like this or asking questions to experienced contractors. Everybody makes mistakes and sometimes their information is out of date, according to new home building practices or building codes.

The Raymond Group City Center Tree House, Las Vegas Construction #2.wmv

"The Tree House" featured in the attached time lapse video is the sculptural centerpiece of the new Sobella Retail space of The Crystals at City Center in Las Vegas. The video reveals the structure's daily progress from start to completion, from one point of view. The Raymond Group's role in the project included framing, drywall, taping, painting, wood cladding installation, as well as BIM components. Below is a description of The Tree House provided by McLaren Engineering, who performed the complete structural engineering down to the main floor, the bulbed-out mezzanine floor, and support from the roof. "This Tree House is not some rickety structure thrown together by a group of 12-year-olds from scrap lumber in dad's garage. Nor is it a pre-fabricated tree house kit with a slide, fire pole, and rope swing like those sold in Wal-Mart. No, this is altogether different." "The Tree House is a two-story, free form, wood clad structure that seems to defy gravity, sitting precariously on a narrow base, spreading out to envelope part of the mezzanine floor, and then reaching away from its support to the skylight above. It appears to be made from horizontal and vertical slices of curved wood, and contains illuminated faces. The upper "oculus" allows light to shine inside the encapsulated bar, which bulbs out from the mezzanine." "...Each structural member and connection experiences unique stresses, so each had to be analyzed individually. The connections of the secondary "ring ...

Finding Grants for Green Construction

When it comes to new construction techniques, grants are often a way to cut costs. Federal grants for green construction are plentiful with billions literally available.

A federal grant is an award of financial assistance from a Federal agency. It is intended to carry out a public purpose or support or stimulate a purpose that is authorized by a law of the United States. Federal grants can be found and applied for electronically. The site Grants.gov is the central clearing house for Federal Grants.

There are twenty six different agencies that offer over 1,000 grant programs. The grants that apply to green construction are mostly offered by the U.S. Department of Health and Human Services. The total amount of grants available exceeds $400 billion dollars. The grants offered by the feds fall into twenty one categories. The categories that have the most impact on green construction are Energy, Environmental Quality, and Health.

Most of the grants are directed toward specific geographical areas. Some of the major concerns of the grants include water quality improvement and the prevention of urban storm water runoff. Many of the grants are connected with the Leeds certification program. Leeds stands for Leadership in Energy and Environmental Design. It is a program that is run by the United States Green building Council and it establishes green construction standards and awards certificates to those that maintain these standards.

Although there are federal grants available, it is on the state and local level that the large majority of grants can be found. The green movement is a grassroots type of thing that appears to be strongest at the local level. Environmental concerns are often very local, and the problems that have been caused by the neglect of the environment are local as well. The pollution of waterways is a good example of this. grant programs exist that are directed at the Great Lakes or at Puget Sound, for example. States that are bordering these waterways usually offers these grants. The idea of environmental impact areas has led to the localities that border or are inside the impact area being the best source of funds for projects that will address the problems.

Private foundations like the Kresage foundation are among the best sources of green construction grants. The Kresage foundation has been offering grants under their Green building Initiative Program. It is specifically geared toward the area of planning and design. While it is true that State, local, and private foundations are the major sources of grants that can be considered pure green building, the federal government is also a source. Research is the key to finding a grant for your project, so take the time to explore the various options mentioned above.

Evolution of Construction Hard Hats

The helmets were over a hundred years ago by Bullard, had grabbed a family of manufacturing personal protective equipment. Now specializing in industrial head protection, including the construction helmets. In the beginning, there was no protection for the head in the construction industry. Since the passage of time and the recognition of security measures, has designed a helmet like a baseball cap was. It 'was a small, stiff leather and shellac on board. Itwas used primarily by miners.

In the course of 1915 work began on the hats hard drive Bullard, also known as helmets that date. It was originally made of steamed canvas, glue and black paint and was known as "hard-boiled is. This proved to be a source of inspiration for the production of helmets for construction. Bullard, in collaboration with the engineers of that time to develop a helmet that protect workers from the consequences of falling objects could, design. Therefore, the mining helmetTransformation into a durable construction Hard Hat.

The first construction hard hat was made of aluminum, which is very robust and relatively easy at that time. They were a very effective protection against falling objects and the bad weather, but very dangerous for use in electrical engineering. The reason is that aluminum is an excellent conductor of electricity. In 1940, Bullard provided with three ribs, heat-resistant fiber is difficult. The fiber was soon replacedfrom thermoplastic material due to the cheaper and more suitable for heat resistance.

Introduced in 1980, Bullard has once again a revolutionary new hard drive. This time, during the design and manufacture, the hard disk, the emphasis has been placed on the correct setting for work-camp. Such labeling also in a new era in standards and safety devices for protection of the head has helped. The new design incorporates an anti-slip ratchet helmet suspension, with a button on the back for easy sizing. Thisparticular model, known as the R 3000 is known, is composed of polyethylene. This makes it extremely lightweight, durable and easy to mold and does not contribute to the creation of electricity. The plastic is treated with a UV inhibitor to protect it in an open environment.

Many other accessories can be added to the normal helmets. Face protection, sunscreen, plants for light, the ear and neck protectors, hearing protectors, blankets absorb perspirationLining of the hat, radio, pagers, walkie-talkies and cameras are just some of them. But the future of the hard hat can be ventilated. This will help to ensure that the helmets in hot portable for workers in extreme climatic conditions, as well as normal conditions.
