The Benefits of Starting a Concrete Block Manufacturing Business

Chances are, if you’re considering starting your own business, you’re probably not thinking about creating and selling concrete blocks. I mean, when you think about starting a business, you probably consider offering a service you know how to provide, or selling a cool retail gadget online, or maybe writing a book or something. But a concrete block business? I’m sure that never crossed your mind.

The truth is, starting a concrete block business is one of the best things you could do for yourself! The biggest problems a new business owner faces are start-up costs, finding and developing a market for his products, and determining a critical benefit to use in his sales message and marketing.

But with concrete blocks, you don’t have to worry about making sure you have a market to sell to – concrete blocks are in high demand all the time!

Think about it – highway construction, new office buildings, new retail spaces, new schools, new bridges – all of these structures require concrete blocks! As long as builders continue to be contracted to put up buildings, bridges, and new highway overpasses, they will continue to need concrete blocks manufactured and delivered to their work sites.

The second reason why a concrete business would be a fantastic business to start is that you have many different options of equipment to buy. You don’t have to have a lot of money to purchase a small economy sized machine to get your business started, and then as your business grows you can upgrade your equipment.

Of course, another reason that becoming a concrete manufacturer is a good idea is that concrete is heavy, and it’s expensive for a builder or contractor to transport concrete from another city. By becoming a concrete manufacturer, you can market directly to your local area and save your customers money!

To sum it up, a concrete manufacturing business would provide you with instant clientele (any local builder, highway repair contracting companies, commercial builders, etc), instant sales message benefits (save your local customer transportation money), and options for economical business start-up.

If you do decide to launch a concrete block manufacturing business, your best bet is to find someone in the industry who would be willing to help you start your business by counseling you on which machines to buy, how & where to start your business, and details you need to know before you get started.

Why Are MEP Projects Late and Over Budget?

MEP (M&E) design and installation is a fundamental element of overall building design process as it directly impacts and influences the use and ongoing costs of the building. Sustainability and conservation issues are important additional factors influencing MEP (M&E) design and place further pressure on effective design while also operating in a profitable environment.

It is common knowledge that the margins involved in MEP (M&E) projects are precariously tight, however instead of managing risk to manage margins, the pressure (from General Contractors and Clients) to act quickly has meant that margins have been squeezed – to the point of loss in many cases. The industry has found it difficult to move from a “reactive site-based position” to a more balanced “pro-active” position that involves greater foresight and planning.

To understand why MEP (M&E) projects are continually over budget, one may find it easier to look first at a different industry entirely. So for example, one could look at anything ranging from manufacturing IT equipment to developing and launching a new software tool to motor vehicle manufacturing. In all of these examples there is a fundamental project cycle that is followed every time. This involves a series of stages which ensure that the output is understood and “tested” before something is built or put into a live environment. The testing, which is fundamental, includes comprehensive risk assessments at several stages and mitigating action to manage such risks.

Taking vehicle manufacturing as an example, at a very high level there are three key stages/elements involved. Firstly, there are individual components (or parts), secondly there is an initial assembly of parts (to make the vehicle) and thirdly there is a mass assembly process. Taking the components first, all components are designed and tested, in detail, in a virtual environment, usually with prototypes being developed for further testing before the finished component is ready. Turning to the “initial assembly of parts” that make up the vehicle. This is very detailed research and development process which utilises a process of virtually built and tested vehicles usually over a period of years. Only once testing is complete is a prototype started which is built, tested and re-built. The vehicle manufacturer will then move to mass manufacture in a production line environment. The production line itself is subject to extensive efficiency and accuracy improvement measures – on a constant and evolving basis. However, once the production line activity begins then there are NO SURPRISES in most cases and every element that is introduced to the line for a vehicle that is already tested is a) known, b) tested and c) works/fits.

In short, vehicle manufacturing utilises extensive planning, virtual testing, actual product/component testing and constant quality control during component manufacture and during the assembly process. There are no surprises or reactive responses during the production line phase of the projects and this is why profitability is in the hands of the manufacturer (and the market of course!).

Now, compare this with MEP (M&E) projects. Firstly, assuming that the engineering components (whether these are pipework, electrical or ductwork elements) are all tested and proven, the challenge for the engineer or sub-contractor is in the assembly of parts and then the installation process on a mass/large scale. As we know, most buildings (excluding new homes or similar repetitive designs) are unique so whilst the engineer is using components that are tested and is usually aware of how those components will work together, he/she will not usually be aware of all of the other factors that inhibit the ‘assembly’ and ‘arrangement’ of MEP (M&E) services. The challenge for MEP (M&E) projects therefore is not concerned with component testing and knowing how the components fit together but rather with site based component assembly, arrangement and installation.

To appreciate the challenge facing the MEP (M&E) industry one has to understand more about the building services design and detailing process. An MEP (M&E) design is completed by one party (the Consulting or Designing Engineer), this is usually a high level design and therefore cannot be easily tested at this stage as it has not taken into account several ‘other’ conditions such as, a) eventual procurement decisions that may lead to changes in sizes and specification of equipment and plant, b) position of other disciplines (e.g. any steel or structure), and; c) in some cases even other MEP (M&E) disciplines (so ductwork design may not have taken into account the plumbing design).

This high level design is then passed on to the next member of the supply chain (commonly referred to as the Building Services or MEP (M&E) Contractor/Trade) who is responsible for planning the site based assembly and installation. This ‘passing-on’ of a design obviously carries some risk but this process is commonly undertaken for MEP (M&E) projects due to contractual and financial reasons as well as technical expertise. As such, the Trade/Sub Contractor has responsibility for taking the design to a detailed level to allow the ‘other’ conditions to be assessed and risks to be mitigated. The Trade/Sub Contractor will detail the design to ensure that it is updated to include his/her preferred materials and plant, that it meets access requirements, it includes space or information for fixing and bracketing and be also to sure that it can be physically installed in the building. Once these elements are met and he/she is confident that the components in the design are not interfering with other disciplines (whether structural or other MEP (M&E) elements) then this first challenge for the Trade/Sub Contractor can be considered complete. This first stage is referred to as MEP Coordination (M&E Coordination) which is the term used to describe vertical and horizontal, interference free drawings.

The second challenge is to manage the installation (or assembly) work, this may involve a degree of pre-fabrication based on the design that has been detailed and the extent to which the building will allow pre-fabrication elements. Whether pre-fabrication is used or not the time and cost of the installation process is directly influenced by the accuracy of the drawings.

As well as using the detailed design for installation, the Trade/Sub Contractor will also use the detailed design output (usually a series of drawings) for creating a schedule or bill of quantities. This is a manual process that takes time and is subject to human error once again. However, it is vital to ensure that this is carried out correctly as it affects estimates and quotes – all of which affect the increasing accountability that MEP (M&E) Contractors/Trades are responsible for.

Traditionally, Trades/Sub Contractors created their detailed design (from which they also extract quantity information) using polyline software – a fairly primitive tool by today’s CAD (Computer Aided Design) standards, to create two dimensional, detailed, technical drawings. The key issues arising from use of polyline software tools are that, a) it takes a long time to produce the drawings – as they require a lot of overlaying and experienced insight, and; b) there is no easy or quick way of validating/testing the drawings – checking would require a manual review which is of course open to human error. Finally, due to the time taken to create and check the drawings, information such as bracketing, hanger locations and their sizes are typically omitted from the drawings – introducing further risk. Of course there are a series of other risks that are inherent in MEP (M&E) projects including the need to ensure the use of the latest set of constantly changing and re-issued design information from other disciplines.

As a result of these issues, MEP (M&E) projects are usually not designed in enough detail and certainly not tested to the degree that they should be. Compared with other industries such as IT development or vehicle manufacturing the acute lack of testing for the final stage (assembly at site level) has varying degrees of effects on the outcome of MEP (M&E) projects.

Working with the detailed design as it is means that any issues that do exist within the design (i.e. procurement or spatial clearance issues) will impact the Trade/Sub Contractor which will result in time delays and additional costs – both of which affect eventual profitability of the project. The reality is that in most cases contractors experience problems during the installation phase of projects which are caused by poor drawings standards and quality levels. Such problems result in spiraling costs and a complete lack of control in most cases. On site problems include:

1) Clashes of MEP (M&E) services with other MEP (M&E) services as well as architectural and structural elements – the resultant delays and on-the-spot fixes result in labour and equipment costs that have a critical impact on budgets.
2) Installers not being able to fully understand the drawings and therefore misinterpreting them – resulting in errors and then corrective work.
3) Bracketing and hangar locations being compromised due to ineffective layout drawings – requiring site-based planning and installation.
4) Lagging and insulation of services being affected – affecting MEP (M&E) service performance.
5) Service access areas and access locations being affected due to poor planning – requiring site based resolution and dealing with subsequent knock on effects.

Trade/Sub Contractors are used to this of course and they manage this eventuality by ensuring that adequate site based resources and budgets are in place to manage ‘on-the-spot’ issues at site. Although the cost of additional, site-based, manpower and equipment far outweighs the cost that may have been incurred during the detailed design phase this has not deterred Trade/Sub Contractors from working in a reactive manner. In actual fact higher site based costs are actually helping to cover up the real issue of a poorly detailed design that has failed to identify and address issues during the detailed design (or ‘detailed coordination’) phase of the project. Had the design been detailed before moving to site, then site based costs and time could be controlled and profitability, and even overall project costs, for customers could improve considerably.

Collectively, the failure by Trades/Sub Contractors to create a detailed design with the best tools available; the apparent need to rush to site and start work (as a result of pressure from General Contractors and Clients); and the need to bridge overall project delays during installation stage (as a result of pressure from Project Managers) are all factors working against the Trade/Sub Contractor. One would argue that the only element that the Trade/Sub Contractor can directly control is the “detailed design”. If this is ignored to the extent that is currently the case, then MEP (M&E) project profitability will remain challenging at best.

So as can be seen, compared to manufacturing or IT industries where a thorough and detailed design process exists, MEP (M&E) projects are ill-tested therefore there is a higher propensity for them to fail. By accepting the risk of a poorly designed project the Trade/Sub Contractor is compromising not just profit but also his reputation and future success.

Notes:

In writing this article we recognise that there are many reasons affecting profitability and performance including
a) choice of, and training of personnel,
b) choice of suppliers and partners
c) weak design execution,
d) unrealistic time frames for completion;
e) failing to detail the design and test appropriately.

This article is concerned with e) failing to detail the design and test appropriately. Our next article will feature more information about how to succeed in MEP (M&E) projects – including the approach now being taken and also how the industry has responded with lean methods and processes.

MEP (M&E) is short for Mechanical, Electrical and Plumbing which are the three main trades and components of building services. MEP is the term used commonly in the US and India while the term M&E is commonly used in the UK, Australia and Canada. In the Middle East the term is commonly referred to as Electro Mechanical Services.

A Guide to Pilates Equipment

There are endless options for exercise videos and equipment that you can buy to use in your home, if you are trying to shed weight and shape up. However, care must be taken that you do not concentrate on just one part of your body.

The most popular of all equipment is the Pilates Reformer. It is a sophisticated system of springs, straps and pulleys. You can perform more than 100 exercises on this versatile piece of equipment.

There is a gliding platform on which one can sit, kneel, stand or lie on the front, back or side. There is a foot bar which is pushed and pulled by the user using the arms, legs, wrists and ankles to slide back and forth along the rails in a controlled manner.

The Pilates Reformer is recommended for establishing torso stability and postural alignment. The adjustable springs allow for progressive resistance, which helps to lengthen and strengthen the muscles.

The Reformer is a fixture in Pilates studios and gyms as well as places like rehabilitation clinics. A more economical, compact, and portable model such as the Allegro is available to cater towards group classes.

Prices are in the $2000-$4000 range for various models of quality Reformers.

Another popular piece of equipment is the Pilates Cadillac, which is also known as ‘The Rack’ and ‘Trapeze Table.” It is one of the most effective and versatile pieces of exercise equipment, and is a bridge between exercise and physical therapy.

The Cadillac is a raised horizontal table-top surrounded by a four-poster frame on which various bars, straps, springs and levers are fixed. Standard models include a push-through bar (which can be sprung from above or below), a roll-down bar, a trapeze or cross bar, arm springs, leg springs, thigh and ankle cuffs and even fuzzy hanging loops.

Several manufacturers have combined the Reformer and Cadillac to make hybrid models.

There is also Pilates Chair, also known as the Wunda Chair, for carrying out more than 75 exercises involving push-up-like moves with the arms. The price of a basic Pilates Chair starts at around $700 but can be more than $1200.

Pilates Ladder Barrels, consisting of ladder-like rungs and a rounded barrel-like surface, enable a multitude of stretching, strengthening and flexibility exercises. Professional-quality ladder barrels come in the $900 to $1500 range.

For mat workouts, there are Pilates Arc Barrels, which are upholstered arches that help support the back and shoulders. They are great rehabilitative tools for those recovering from stress, tension or injury. They range in price from $130 to $230.

The Pilates Spine Corrector has a sort of a whistle shape, with a semi-circular arch plus an angled step or seat. The unit is effective for stretching the spine and shoulders in a way that is safe, stable, and supported. Pricing is in the $300 to $450 range.
