The Lean Building Journal in a 2009 white paper pegs the ratio of wasteful or non-value-added activities in a typical building task at 55% to 65%. The white paper-Creating Value: An Adequate Way to Get rid of Waste in Lean Design and Lean Production goes on to say, “Developing worth and only value is the very best method to decrease waste in style and construction.”

Needless to say, the construction market is severely broken and requires fixing. How does the industry rise up and fulfill the difficulties of consumer need for greater quality, improved success, and the shortage of proficient employees? The initial step is to cast aside the not developed here syndrome and welcome a time evaluated producing service -the Toyota Production System-commonly called Lean.

Why should building and construction company managers even consider Lean as a method to improve their company? Here are some eye opening realities about the U.S. building and construction industry:

60% to 85% of construction time is spent waiting or repairing mistakes
The average construction worker operates at 40% efficiency
Crucial scarcities exist in qualified and skilled employees
The return on equity for building and construction fades in contrast to all other U.S. industries
Customers are frustrated with bad quality, conflict, excessive change orders, and scheduling delays
While Lean is no silver bullet, lean building and construction offers substantial improvements to the issues facing the construction market. If building and construction companies desire to prosper in the 21st Century then they must move toward lean thinking.

Why a lot Waste?

There is a little however growing movement to apply lean principles to building and construction. Applying lean principles to construction truly implies applying them to project management. This transformation includes mapping your building processes, figuring out the most efficient work flow and developing a pull system. How do you produce a pull system? As a specialist you can start by taking a look at exactly what the finished project should be, and after that work in reverse, recognizing each preceding step. When they ought to take place, downstream procedures identify what the upstream processes will be and. Taking this view of the job will help you control the work circulation. You need to likewise take a look at developing value stream or process maps of your task support processes as well as job processes. Procedures like job setup, estimating, payroll, accounts payable, acquiring, tool and material handling ready prospects for mapping.

Why so much waste? Construction projects are so fragmented. Lot of times subcontractors do their work neglecting how exactly what they do impact the work of other subcontractors. We call this the “throw it over the wall’ mentality. One functional department (in this case subcontractor) finishes its part of the project and tosses it over the wall to the next department (subcontractor) who throws it back over the wall since it isn’t really. This mindset sub-optimizes the efficiency of the whole job developing quality and schedule issues.

Lean thinking is a brand-new method to manage building. Many individuals object since they believe lean is a production strategy and has no application in a “special” market like construction. The goal of Lean Process Improvement is to optimize worth and eliminate waste utilizing strategies like one-piece circulation, Just-in-time shipment, and stock decrease.

The Need for Change

The building and construction industry is broken and the 5 truths listed below demonstrate why the market needs to change:

Crucial shortages of certified, competent employees are anticipated to just become worse.
Regardless of the building boom of 2006, Business Week’s 2007 Investment Outlook Report showed the return on equity (ROE) for all U.S. industries was 17.9 percent, while the ROE for the building and construction industry was a simple 9.7 percent.
Market clients are irritated with bad quality, conflict, excessive change orders in quantity and dollar value, scheduling delays and litigation.

Lean thinking is a brand-new method to manage building. Many individuals object because they think lean is a production strategy and has no application in a “unique” market like building. Using lean concepts to building and construction actually implies using them to project management.

If it takes 6 months to develop a home, then 85 percent of the time is invested in two activities: waiting on the next trade to show up, and fixing errors
Clemson’s Professor Roger Liska conducted an analysis of productivity on the building and construction market and found that the average building employee runs at only 40 percent effectiveness.

While Lean is no silver bullet, lean building offers substantial enhancements to the issues dealing with the building and construction market. If construction companies want to prosper in the 21st Century then they need to move towards lean thinking.

You see the siding, the windows, the front door, and way up above, you see the roofing system. Does the roofing have asphalt shingles? Maybe it’s made of metal or rubber tiles?

The Roof Deck

Keep in mind, if your roofing deck is decomposing or damaged in any way, people walking on your roofing system might possibly break or crack through the wood, triggering additional damage to the roofing system, such as to the shingles … and to the individual who strolled on it! However, many roofing decks can hold up against a bit of exposure to water or ice prior to it needs to be changed.

On Newer Houses, sheets of plywood or OSB boards are fastened on top of wood trusses in your attic to form the roofing system deck. When the time comes for you to change your Roof System, keep in mind to have your Calgary Roofing Contractor change any and all damaged wood.

Your wood roofing system deck is comparable to an autos metal body. Without a roofing system deck installed on your house, there would be nowhere to install your Shingles. And of course without the shingles, your roof deck would rot away due to exposure to the sun, ice, rain and snow and etc.

Drip edge and Rake edge is the first part of the Roof System to be installed. It is a narrow and long piece of metal which is installed along each end of your Roof Deck, ie: along the eaves trough and along the gable ends.

Lots of new homes and/or low budget roofing systems do not have drip edge set up in order to enable for more cost effective roofing rates. We advise nevertheless that Drip edge and Rake edge be set up on every Roof System, no exceptions.

If your Roof System does not presently have drip or rake edge installed, do not panic, you’ll make it through well enough. Simply know that when your roof has to be replaced, the Roofing Contractor you may have to change a few of your wood Roof Deck on an as required basis.

Metal: Skylights and chimneys

Every chimney and skylight needs exactly what is described as “a back pan”, which includes sheet metal folded at around a 90 degree angle (depending upon the slope of your roofing system) and tucks under the shingles and up under the counter, siding or stucco flashing on the chimney or skylight. Every back pan needs a small 2″ section of metal sticking out 1″ or more from either side of the chimney or skylight to divert water far from the corners. Water ought to strike the metal back pan and be directed away on either side where it can continue its face the eaves trough.

Arguably the most vital part of every complete roof system. The metal installed in the chimneys, valleys and skylights take the impact of water flow on every roofing. Inadequately installed, a brand name brand-new roofing system can make a waterfall out of your living room.

Metal: Valleys

In the exact same way water runs along the valleys between 2 mountains, water runs along the valleys on your roofing system peaks. Valleys normally receive the highest concentration of water streaming through them, for that reason installing them properly is very crucial!

As pointed out in the Leak Barrier area, valleys have leak barriers set up underneath them. Despite the fact that some Building Codes do not need such a leakage barrier to be installed, we suggest installing one constantly in every valley.

A word of care: Many roofing contractors install valleys in a style described as ‘closed’. A closed valley includes Shingles woven inside the valley, instead of an ‘open’ valley which has sheet metal running from top to bottom. Both the ‘open’ and the ‘closed’ design of setup are acceptable by the a lot of Building Codes and by a lot of producers, nevertheless, the ‘open’ style installation has actually consistently out carried out the ‘closed’ design … and expenses precisely the exact same cost to install. Ask your Roofing Contractor to utilize the ‘open’ design of installation for your roofings valleys, this might conserve you from having to replace your roofing system too soon as well as can prevent headaches in the long run. Generally, an ‘open’ valley is installed with a 30 gauge sheet metal, 4′ large, can be found in 10′ sheets. This metal can be purchased in any color to match the shingles on your roofing system.

Leak Barrier

If you’ve ever taken a look at your roofing system throughout winter, you’ll observe how ice and snow develops along the length of your eaves troughs and inside the roofing system valleys. Just like Rake Edge and Drip Edge, some Building codes need Leak Barriers to be installed and some Building Codes do not. In Alberta, the Building Code needs a leak Barrier to be installed on all eaves trough and valley locations of a Roof Systems because of concerns related to such snow and ice develop. As an optional upgrade, some high-end roofing system systems even have leakage barriers installed on top of the whole Roof Deck (instead of just along the special locations we just pointed out) where normally a basic Roof Deck Protection would usually have actually been set up.

Practically all roofing systems in Calgary, Alberta have leak barriers set up, and many different types of leak barriers are available in today’s market, each using a various level of functionality, warranty and reliability and produced by various makers.

Choosing a proper Leak Barrier and installing it correctly is an essential step in every Roof System. Talk to your Roofing Contractor to read more about leak barriers, how to select the right one and ways to pick a Professional Roofing Contractor to install it.

Consider a leak barrier as a “second layer” of security for your Roof Deck. A backup plan, if you will, as well as a protection against moisture build up. Leak barriers are almost constantly installed on top of the Drip Edge and Rake Edge metal along eaves trough locations, gable locations and valleys since of the threat these locations position for leaks, ice develop, shingle degeneration and water back flow.

Roofing system Deck Protection

Roof Deck Protection is very similar to a Leak Barrier. The difference is that Roof Deck Protection is set up on the whole Roof Deck area instead of only on “special areas” as we mention in the Leak Barrier area.

Lots of brand-new houses and/or low budget roofing systems do not have drip edge installed in order to permit for more affordable roofing costs. Ask your Roofing Contractor to utilize the ‘open’ style of installation for your roofs valleys, this might save you from having to change your roof system prematurely and also can avoid headaches in the long run. If you’ve ever looked at your roofing during winter, you’ll discover how ice and snow builds up along the length of your eaves troughs and inside the roofing valleys.

Selecting a dependable Roof Deck Protection is an important part of a quality Roof System.

A word of care; most roof companies utilize felt paper as Roof Deck Protection. Utilizing felt paper is a appropriate and basic practice, some concerns can emerge if the felt paper becomes wet during or after the installation. Ever discover how paper tends to curl when it dries after it was wet? In a similar way, felt paper can curl if water or excess moisture touches it. For this reason, and because the expense is rather small, we suggest installing a higher quality Roof Deck Protection such as a GAF/ELK Deck Armour. For a fairly small extra expense, you’ll be rewarded with a much more trustworthy Roof Deck Protection.

Usually, Roof Deck Protection is an action lower in quality than a Leak Barrier. As with Leak Barriers nevertheless, there are several kinds of Roof Deck Protection readily available to select from ranging from fundamental felt/tar paper to advanced plastic woven sheets of rip and wrinkle proof product.
