5 Ingredients in the Constructions of a Road

5 ingredients in the Construction of a Road

Have you ever baked a cake and realised you forgot to add the flour or the baking powder? What tends to happen? Your cake flops or does not rise. Building a road is similar, but a lot more complex. There are so many ‘ingredients’ and important aspects that need to be considered before and during the construction of a road.

The first step to constructing a road would be planning. Your engineer/consultant would come on site and decide what type of road will be built and what materials would be used to construct the road. This will all depend on how much traffic will occupy this road. Even the simplest of roads can take up to months or possibly even years for the planning of the road. The engineer will need to evaluate many factors such as the environmental impact of the road, the availability of materials needed to construct the road, will the road be safe and, the most important factor, the cost of the road. These plans will be written into a final proposal where the consultants will need to evaluate these plans. Meetings will take place with all parties concerned and all the pros and cons will be discussed in vast detail. Without proper planning and careful consideration of all these factors, there is a chance that the foundation will collapse.

Shortly after careful planning and long and tedious meeting’s the plan will either be approved or rejected. We are going to assume that the planning was approved. The next step would be the construction of the actual road.

Ingredients used to construct a road:

 

1. The standard Foundation:

Bulldozers and graders, which are two types of machinery, will be used to flatten the ground surface. This ground layer will make up the bottom layer of our road

2. Gravel:

The gravel will be added in layers where a roller machine will be used to roll over this surface to ensure that the surface is compact and flattened

3. Drainage facilities:

Drainage facilitates play a huge role in ensuring that the road is safe at all times from water backlogs. We are not able to control the weather and for this reason, we need to ensure that the road never gets saturated and water-logged. Firstly it is not safe for drivers on the road and secondly, the road will soon disintegrate and start deteriorating over time. Examples of drainage facilities would be drain and storm water sewers.

Once the foundation is complete and compact and has been inspected by the consultant, it is time to pave the road!

4. Asphalt / Bitumen

Asphalt uses an oil based substance called bitumen to make sand and crushed rock stick together like a glue-like substance. The asphalt is heated to +- 300 Degrees Fahrenheit (148,88 Degrees Celsius), where it

will be transported to the site where the construction team will spread the mixture evenly across the smooth gravel service. The mixture is rolled over the gravel surface where it will form a solid layer on the top.

5. Concrete Slabs

The finishing touches will be the concrete slabs that are laid on the side of the roads. Workers will pour liquid concrete into a steel mould called forms. A finishing machine is used to shake these moulds to ensure the mixture is distributed evenly for an even finish. The concrete slabs are laid alongside the road where incisions in the road are made to allow the concrete to expand and contract depending on the temperature, this will ensure that the road does not crack

Every day we take our course of life, may it be a trip to the shop or work and take for granted these roads that we drive on. Most people think they just appeared or are set up overnight by machinery. The planning and work that goes into these roads are far more complex than most can imagine.

L2B Blog: What is the importance of appointing an architect?

What is the importance of appointing an architect?

What is the importance of appointing an architect?

What is the importance of appointing an architect?

What is Architecture?

Architecture is the art of building. It satisfies a basic, universal human need for shelter.

An architect is an artist who designs structures to enclose residential, commercial, or public space. Architects work with construction technologies, building materials, topography, contractors, and governmental regulations within a project budget to satisfy their clients’ wants and needs.

To practice architecture means to provide services in connection with the design of buildings and the space within the site surrounding the buildings, that have as their principal purpose human occupancy or use.

Professionally, an architect’s decisions affect public safety, and thus an architect must undergo specialised training consisting of advanced education and a practicum (or internship) for practical experience to earn a license to practice architecture. Practical, technical, and academic requirements for becoming an architect vary.

In the architectural profession, technical and environmental knowledge, design and construction management, and an understanding of business are as important as design. However, design is the driving force throughout the project and beyond. An architect accepts a commission from a client. The commission might involve preparing feasibility reports, building audits, the design of a building or of several buildings, structures, and the spaces among them. The architect participates in developing the requirements the client wants in the building. Throughout the project (planning to occupancy), the architect co-ordinates a design team. Structural, mechanical, and electrical engineers and other specialists, are hired by the client or the architect, who must ensure that the work is co-ordinated to construct the design

General Points

  • Architects are trained to take your brief and can see the big picture.
  • Architects look beyond your immediate requirements to design flexible buildings that will adapt to the changing needs of your business.
  • Architects solve problems creatively
  • When they are involved at the earliest planning stage, they gain more opportunities to understand your business, develop creative solutions, and propose ways to reduce costs.
  • Architects can save you money by maximising your investment.
  • A well-designed building can reduce your bills now and increase its long-term value.
  • Architects can manage your project from site selection to completion.
  • In many building projects, the role of the architect includes co-ordinating a team of specialist consultants such as landscape architects, engineers, quantity surveyors, interior designers, builders and subcontractors.
  • Architects can save you time.
  • By managing and co-ordinating key project elements they allow you to focus on your organisation’s activities.
  • Architects can help your business.
  • They create total environments, interior and exterior, which are pleasing and functional for the people who work and do business within them.

And hopefully, you end up with a building that is considered both beautiful and functional. Some Architects are hired for their creativity and bold designs, which result in buildings and structures that dominate the skyline. See 30 St Marys Street or more commonly known as The Gherkin. These buildings can often become tourist attractions and works of art in themselves. See Park Güell in Barcelona, which was designed by architect Antoni Gaudi.

Unfortunately, like all art; the beauty is in the eye of the beholder. In some cases, buildings can be judged by “The Good, the Bad and the Ugly”. Some buildings with the striking designs are considered eyesores or worse. Worse being “badly” designed. There are stories of highly polished exteriors of buildings setting fire to people and things when the sun hits them at the wrong angle. See Vdara Hotel, Las Vegas:

Or huge skyscrapers, that apparently were designed and subsequently built with no space left for the elevators shafts and the machinery required for them. See the Intempo Skyscraper in Benidorm, Spain with its 47 storeys:

Hiring an architect can save time and money, and allow you access to expertise and creativity, and results in the art that we live in and experience daily. But ensure you hire the good.

L2B Blog: Ways that technology is helping to build the Construction Industry

Ways that technology is helping to build the Construction Industry

Ways that Technology is helping to build the Construction Industry:

As technology continues to progress, it is not hard to see how it spills over into the construction industry. From machinery to apps on your phone and the advances in materials, each has an integral role:

To name a few groundbreaking Construction Projects from all over the world: In 2015, a Chinese company built a 57 story building in 19 days. The Burj Khalifa, the current world’s tallest building at 828m, completed in 2010. In my opinion, one of the most awesome feats of technology: the underwater dining room of the Kihavah Maldives. A house being built by a 3D printer in a record breaking 24 hours. If it was not for technology evolving, these Projects would not be done quickly, or even be possible.

As people, it is in our DNA to be creative, which leads to people continuously developing technology to be bigger, better, smarter and faster. The same applies to the construction industry.

Pre-1904, if you were building a house you would be mixing your concrete by hand. In 1904 Richard Bodlaender patented what we know today as the portable cement mixer, which has since been modified with an engine attachment. 1917 saw the birth of the cement mixing truck, which only reached its full potential in 1957 with the invention of the cement pump, allowing us the capabilities to pour concrete at an incredible rate: this cement pump has micro-evolved since the 50’s. I suppose all methods of mixing concrete are still used today depending on the budget of the project, however, the most effective method would be the use of the truck with a cement pump.

In our lifetime, we have seen “new technology” turned into dinosaurs, like dial-up internet (thank goodness that is gone). We’ve got smartphones, that have come a long way since its brick size predecessor and at the rate we are going, tablets will completely eradicate the entire species of the laptop computer. We have access to apps and websites on our phone, as long as we have a positive credit in our data bundles. Thanks to apps we are able to carry around a set of building plans and specs in the palms of our hands. By adding in a few figures, apps can work out the costs of the project for us. The diary industry (classic quoting system) is slowly eroding as we have our whole world on our phones. Advertising has progressed from newspaper classifieds to flyers/banners to social media (The newspaper is online these days as the world calls for a more paperless society). If you are avoiding social media, you will be left in the dark ages as your online presence is vital to your survival. Which is easier? To Google a phone number from your device or to look for a number in your phone book when you get home later, real world people want real-time answers.

Where does that leave us as South Africans?

We need to move forward, to adapt: Which has more life in it, the river or a pond with no inlet or outlet? To change our marketing strategies, to buy or develop new technology, to be more effective with the little time we have in the day. If we are not developing or inventing our own technology we will always be behind those who do. I think there is plenty of money to be made for those who can think ahead, keep up with technology, invest in development or purchase machinery so we can keep it local and sow into our own economy. Let us not be stuck in our ways, but keep adapting. I’m not saying throw the baby out with the bathwater, but be willing to embrace technology. Most importantly build your online presence.

L2B Blog: Commercial Construction & Renovation

Commercial Construction & Renovation

According to itsallaboutbusiness.com, “Commercial construction is the business of building and selling or leasing manufacturing or assembly plants, medical centers, retail shopping centers and standard space for offices. The business varies primarily in the size and scale of the operations. Typically, the commercial builder either contracts with a company or organisation to build the facility or builds the facility on speculation that it can be leased or sold at a later time.”

Taking the above into account lets look at some of the commercial properties making headlines in South Africa.

In 2011 Aurecon’s Offices in Century City, now known as Aurecon East, was the first building in South Africa to be awarded a 5-Star Green Star SA Office Design v1 rating by the Green Building Council of South Africa (GBCSA) but they didn’t stop there. In 2016 Aurecon West was completed, the second phase of Offices which also went on to receive a 5-Star Green Star SA Office Design v1 rating. Aurecon’s investment in Century City has inspired a number of other large corporates to relocate to the area.

In 2011 there were only 5 buildings in SA with Green Star accreditation from the GBCSA, to date there are 113 buildings with a Office Design v1 rating and 202 buildings in total with a Green Star Rating.

When you mention Kyalami most will think of the Race Track that was purchased by Porsche South Africa in 2014. Indeed, it is an historic track and recent construction and renovation at the Race Track was completed May 2016 after which it was awarded a Grade 2 racetrack certification by the Federation International de l’Automobile (FIA) and is the only current motor racing facility on the African continent to have the prestigious accreditation. But the Race Track is not the only property making headlines, Kyalami Corner, a 28 000m² retail development is due for completion in March and anticipated to open in April this year and forms part of the larger Kyalami Main on Main development in the area which includes retail, motor showrooms, offices and residential.

Another commercial development close to home is the Liberty Midlands Mall Phase 3 Expansion which will include offices and a value retail centre which was initially announced December 2013, construction was planned to commence in early 2014 and completed by mid-2015. However it seems that there were various delays and Phase 3 looks like it will be going ahead during 2017. Residents in the area have been waiting a while for the expansion and I’m sure many look forward to witnessing the progressing going forward. Watch this space.

The list of commercial construction and renovation could go on…

It’s evident that there is a significant amount of commercial construction & renovation happening in SA and what’s more all the developments I mentioned above can be found on Leads 2 Business. Want to know more? Comment below or contact us.

Building Design & Construction: Interesting Buildings & Structures

Over the ages, there have been many buildings and structures built that have an absolutely amazing design. Some of these buildings and structures have withstood the test of time in ways that newer buildings / structures have yet to experience and only time will tell if they will be able to withstand the forces of nature. Today, I am having a look at some of these brilliant buildings and structures that have captured my imagination.

 

  1. Bridge of Eggs, Lima, Peru

Puente de Piedra (the Bridge of Stone), was built around 1610 by the architect. Juan del Corral, and is referred to as the Bridge of Eggs, due to the belief that the mortar was mixed with egg whites as opposed to water. The bridge is still standing today.

Tenders by CIDB – What do you need to get the job?

What do you need to get the job?

cidb-what-you-need-to-get-the-job

The Construction Industry Development Board (cidb) – a Schedule 3A public entity – was established by Act of Parliament (Act 38 of 2000) to promote a regulatory and developmental framework that builds:

  • Construction industry delivery capability for South Africa’s social and economic growth.
  • A proudly South African construction industry that delivers to globally competitive standards.

The cidb’s focus is on

  • Sustainable growth, capacity development and empowerment
  • Improved industry performance and best practice
  • A transformed industry, underpinned by consistent and ethical procurement practices
    Enhanced value to clients and society

 

Construction companies is South Africa are required to register with the CIDB for various classes of construction works, if they want to be awarded Government tenders, and are assigned ratings based on their financial capability. CIDB ratings, when required, are listed on tender notices and perform two functions: The most obvious being that if a company is not registered in that particular rating or class of work then that company can not be awarded that contract (unless they form a Joint Venture); and the second is that the Rating gives a estimated value for the contract concerned. This is helpful for subcontractors to determine whether it is worth their while to approach those companies tendering.

 

Below is a breakdown of the various Construction works and how the various ratings are determined:

 

Class of Construction Works

 

GB General Building

CE Civil Engineering

EB Electrical Engineering Works – Building

EP Electrical Engineering Works – Infrastructure

ME Mechanical Engineering

SB Asphalt works (supply and lay)

SC Building Excavations, shaft sinking, lateral earth support

SD Corrosion protection (cathodic, anodic and electrolytic)

SE Demolition and blasting

SF Fire prevention and protection systems

SG Glazing, curtain walls and shop fronts

SH Landscaping, irrigation and horticulture works

SI Lifts, escalators and travellators (installation, commissioning and maintenance)

SJ Piling and specialised foundations for building and structures

SK Road markings and signage

SL Structural steelwork fabrication and erection

SM Timber buildings and structures

SN Waterproofing of basements, roofs and walls using specialist systems

SO Water supply and drainage for buildings (wet services, plumbing)

SQ Steel security fencing or precast concrete

How contractor grading designations are determined

 

Your contractor grading designation is determined by your financial capability and your works capability.

 

Your financial capability relates to your financial history (turnover), and the amount of working capital you can muster to sustain a contract, i.e. available capital. Available capital is the sum of total equity, retained income, shareholders or member’s loans and any form of acceptable financial sponsorship.

 

Your works capability is determined by the largest contract you have undertaken and completed in your class of construction works (completed during the 5 years immediately preceding the application).

 

Your contractor grading designation will be used by Government (national, provincial, municipal and state owned enterprises) to qualify your tender to be considered for a particular construction works contract. For example: if you are registered as a 5CE, you will be considered for public sector civil engineering works contracts of a value not exceeding R6.5 million. You may register for different classes of works, for example, you may be registered as a 5CE and as an 8ME. This means that you will also be considered for public sector mechanical engineering works contracts of a value not exceeding R130 million.

 

Determining Financial Capability

The specific requirements that need to be satisfied in respect of the contractor grading designation being applied for, depending on the contractor grading designation applied for, financial capability will be determined from:

  • best turnover from the two financial years immediately preceding the application;
  • the available capital that you are able to mobilise;
  • the contractor must satisfy all the criteria relating to financial capability.

 

 

Determining Works Capability

The specific requirements that you need to satisfy in respect of the contractor grading designation applied are:

 

Designation

Grade 2: Must have completed a contract with the value of not less than R130 000.

Grade 3: Must have completed a contract with the value of not less than R450 000 and either have best turnover not less than R1 000 000 or have available capital not less than R100 000.

Grade 4: Must have completed a contract with the value of not less than R900 000 and either have best  turnover not less than R2 000 000 or have available capital not less than R200 000.

Grade 5 and higher: Must have works and financial capability not less than that tabulated in Table C(i) below, for the  contractor grading designation applied for.

 

Determining Financial Capability

 

 

Potentially Emerging Enterprises

 

A registered, potentially emerging contractor may be awarded a contract at one level higher than the enterprise’s registered contractor grading designation, if the client or employer:

 

Is satisfied that such a contractor has the potential to develop and qualify to be registered in that higher grade; and

 

Ensures that financial, management or other support is provided – in the context of a targeted development programme

  • to enable the contractor to successfully execute that contract.

 

Joint Ventures

 

A joint venture is a grouping of two or more contractors who jointly undertake to perform a construction works contract.

 

Any enterprise that tenders or enters into a contract for construction works with the public sector, must be registered.

Once-off joint ventures do not have to register. Each partner of the joint venture must be separately registered and the lead partner must have a contractor grading designation not lower than one level below the required grading designation in the class of construction works under consideration.

 

The contractor grading designation for a once-off joint venture is assessed by the client, based on:

 

the sum of the best annual turnover of all the members of the joint venture;

the sum of the available capital of all the members of the joint venture; and

The cidb has developed a calculator to enable assessment of joint ventures. This calculator is available on the cidb website at www.cidb.org.za

 

Leads 2 Business subscribers have the option to filter by CIDB ratings as well as set up their Advisory settings, so they only receive the Ratings that they are interested in. My advice in this regard, would be to go “one above and one below”. The idea of the CIDB ratings is progression. New companies start out with a CIDB 1 and as the company grows in experience and financial standing, they would progress up the ratings. So a subscriber would select “one above” (as in a Rating above their current Rating) and select “one below” to make sure that they are notified of any tenders where only the PE (Potentially Emerging) rating has been specified on the tender. Keeping an eye on the next rung up the ladder, but ensuring your foot is still firmly in place on the rung below (if you like metaphors).

 

 

Examples of  tender notices of various CIDB Ratings and Classes:

 

CIDB 1: Upgrading of School Ablution Facilities – DTA 609616

CIDB 2: Supply, Deliver and Erect 6000m wire Barbed Wire Fencing for Bambanani co-op – DTA 609446

Market Intelligence: Tenders by Category

Tenders by Category

tenders-by-category

There are many tenders out there, but Leads 2 Business specialises in the supply of tender notices related to the Building and Construction Industry. Even in this industry, there are different tenders for the different work required. Consequently, we have Tender Categories that are divided as follows:

The Tender Categories assist in making sure that our subscribers can choose to receive the tender notices relevant to them and prevent an inundation of irrelevant information. If the company’s services fall into a very broad category, they can narrow down the tender information, by making use of our “Keywords” function to assist them in receiving the correct tender notices according to their scope or when they are searching on our website.

Are you involved in any of these Tender Categories and interested in receiving leads?

The timing of Tenders – Award Dates

Award Dates

97-blog-award-dates

I work in the Private Projects Department at Leads 2 Business, following the progress of construction developments. Once a project reaches Tender stage, we endeavour to source the award information for the tender linked to that project. In my nearly 5-year experience in dealing with tenders, I have come to learn about a few of the procedures and regulations that need to be adhered to throughout the tendering process. I have no doubt that there is more to learn, but in this blog post I will talk about some of the processes and procedures that I have encountered in the public tendering process, through my understanding.

Public tenders seem to be awarded after a period of between 90 to 120 days from the closing date, however, this time frame could vary – The award can be made before or after this period, provided that the validity period has not expired.

Once the successful bidder is notified, the tender award is not simply finalised with the contract starting immediately thereafter. A public notice should be advertised to indicate the intention to award. There should also be an appeals period, rejection letters, an appointment letter, a contract, and certain construction regulations to adhere to.

Notice of Award / Intention to Award
Once evaluation and adjudication is finalised and a recommendation has been made, the bids should be opened and read out in public, for transparency purposes. A bid register should be published on the client’s website so that the tenderers are able to view the prices that were submitted by the other service providers, should they not have been able to attend the opening of the bids. Successful and unsuccessful tenderers should then be provided with written notice, and a notice of intention to award should be publicly advertised to allow for possible objections from the other bidders.

Appeals Period
Once the intention to award has been advertised, a certain period should be allowed for objections, if any, from other service providers. A tenderer can appeal the award, usually within 14 calendar days (this may differ) from the date of the letter of intent. Clear instructions for the appeals process should be included in the contract documents.

Letter of Appointment
Once the appeals process has concluded, the successful tenderer is issued with an appointment letter. This does not necessarily mean that the award has been finalised. There could be conditions stipulated in the appointment letter which need to be fulfilled before a binding agreement can come into effect.

Binding Contractual Relationship
The contractual relationship begins once the successful bid has been accepted in writing, followed by a written agreement which is signed by both parties. The award can be deemed finalised at this point.

Notification of Construction Work
Should the contract meet the requirements set out in the construction regulation for the Notification of Construction Work, the main contractor must notify the Department of Labour prior to the commencement of construction. A copy of this notice, among other important documents, must be kept in the Occupational Health & Safety File (OH&S File) on site.

Bear in mind that the processes above are not the only ones to consider before the award date is finalised. There are other processes that an award may have to go through, depending on the client’s requirements, the type of goods or services being procured, and even the value of the contract, among others.

The award is not the end of the process. It signals the beginning of the contract.
