Common Mistakes in Bridge Construction

Common Mistakes in Bridge Construction

The best way to avoid bridge failures is to expect them to happen and develop a good risk management strategy. Don’t just wait to cross that bridge when you get there. This is the only way to protect the public from injuries, loss of life, property damage and destruction. Some bridge collapses are mysteries when they first happen. It isn’t until a detailed investigation is completed that the true cause is revealed.

I am going to list a few common mistakes in bridge construction:

1. Poor Bridge Maintenance: The collapsing of bridges could be prevented with more strict inspections and frequent routine maintenance. Rusted parts must be replaced, drainage areas cleared in case of natural disasters and reinforcements added especially when the use of the bridge has increased. The Connecticut Turnpike over the Mianus River collapsed due to the failure of steel pins that had corroded. I can not believe the lack of bridge maintenance! Can’t get over it.

2. Cheap Materials: A bridge is only as strong as what it’s built with. No one likes to spend money, but excessive cost-cutting can leave the bridge vulnerable to collapses. Not only is the bridge put in a more precarious situation, but saving money on materials can also lead to more costly repairs down the line.

3. Design Defect: While some bridges are constructed perfectly with high-end materials, they can still fail if the design is flawed. Bridges with a poor design could fail to hold enough weight or withstand natural conditions. There are bridges whose collapse was unpreventable before the bridge was ever built.

4. Natural Disasters: Today’s changing climate and the extreme weather events associated with it is causing chaotic weather. Most collapses happen on bridges that were built a long time ago when designers couldn’t imagine the kind of storms they’d have to withstand today. We can’t control the weather, but we can build structures strong enough to withstand such natural disasters. There is always room for improvement.

5. Accidents: Whether it’s a truck hitting a support post, a train falling off the tracks or a boat colliding into a foundation, accidents are one of the leading reasons bridges are damaged or come down. Bridge engineers must plan for all types of incidents. They will have to also bear in mind what the future holds for us. Will there be driverless cars, larger ocean tankers, and cruise ships, along with pilotless drones that could impact bridges in the near and distant future? I think it’s possible, most of it is already happening.

I am definitely no expert in any of these aspects, but keep these failures in mind next time you sitting in your car under a train bridge and the robot for you to go is red.

Building relationships to grow your business

posted in: General 2

Building relationships to grow your business

Today is the kind of day where I wish inspiration came out of my shower. I’m no business owner and I don’t have any sort of marketing degree behind my name.

I can tell you however, that a business is only as good as the client it serves, and no business gets far after losing the clients it had.

I promise you that not all of my thoughts come from the shower.
I do think out of the box too.

The key to success is building relationships that go beyond one-time projects and provides value to these clients on a consistent, ongoing basis. You have to learn the rules of the game and then you have to play better than anyone else.

Building business relationships are not like any other relationship with a partner, No. It is much more than that.

Money can’t buy one of the most important things you need to build your business, Clients. You can’t have a million dollar dream with minimum work ethic.

How do customer relationships drive your business? It is all about finding people who believe in your product or service. How are you going to do this? You develop relationships with people who don’t just understand your particular expertise, product or service but who are excited and buzzing about what you do.

Relationships have a short shelf life. “There is nothing i can’t do, except reach the top shelf. I can’t do that.” Don’t be that guy! For crying in a bucket, get the ladder and reach the top. One of the biggest mistakes people make is that they come home from networking events and fail to follow up. Make the connection immediately, It’s easier to keep a connection warm than to warm it up again once the trail goes cold.

I would now like to share my knowledge on how to build client relationships:

 

When you make the right connections you’re much more likely to be a success. E-mail marketing keeps a work relationship strong on a shoestring budget.
Build a reputation by giving away free insight. Come on who doesn’t love free things?

Make the E-mail interesting and worth the read, most important make connection with the same people that shares the same interests and goals as you.

 

 

 

Reward loyal customers and they will reward you, for example the CEO at Leads 2 Business will host a lovely golf day for all our clients. Make them feel special and appreciated.
Once you show them, that appreciation they will be around for a very long time.

 

The saying, “Give and you shall receive” goes a very long way when it comes to this.

 

 

 

Own it, this may be the most difficult skill to master because it hits home morally and shows your human side. When something goes wrong you may have to take the bullet even if it wasn’t your fault or the company’s fault.

If it was you or the company that was in the wrong being respectful and honest shows vulnerability and the ability to take criticism that goes with being wrong.

Step in without being asked, it is easy to help when you are asked. Most people will. People who build client relationships pay close attention so that they can tell when others are struggling.

Offer to help, not just to build a good relationship with your client base, but because you care.

With all this said I would like to remind you to be authentic.

Be genuine. Be real.

 

Here is a quote for the day:

By being remarkable, being genuine, you can be worth connecting with. And you don’t have to have it all figured out perfectly the first time – you can adjust.

~ Seth Godin ~

L2B Blog: Consulting Work in Africa

I hope that my blog doesn’t bore you too much. I like to talk – to the point where I am consciously aware that I am bothering the people around me… and yet I continue. As a mitigating consideration, (fingers crossed) I don’t think I’m boring. The fact that I think I might have the gift of the gab is probably one of the main reasons why I shouldn’t run out of things to talk about. 😉

 

I will be discussing consultants, who are they and what do they do?

 

To be honest, the very first time I heard the word “consultants”, I immediately thought of doctors, I don’t know why… probably because I’m Afrikaans. I lie awake at night sometimes worrying that my words, phrases, and punctuation will end up in court. Why? To be sentenced, of course.

 

A consultant is a person who provides professional or expert advice in a particular field of business to either an organisation or individual. There are various different types of consultants. Consultants are professionals, typically appointed by the client to perform expert tasks on a project.

 

The members of the Consultant team that are likely to be required on most projects are:

*Architect
*Engineers
*Consultants
*Quantity surveyors

 

In this regard, I’m going to focus on Architects.

 

Giving people an exceptional experience, and turning what appears to be nothing, into a space of breathtaking beauty.

 

That is the art of being an Architect. #WeLoveOurArchitects

#SiyawathandaAmaArchitectsAseAfrica #OnsWaardeerArgitekte

 

 

What is an Architect?

 

An Architect is someone who plans, designs and reviews the construction of developments. The architect is acquainted with the tender procedures and building contracts.

 

It’s amazing how opportunities in Africa became extraordinary. With the rapid economic growth, masses migrated into the cities, (which is quite distressing) how would you plan for expansion of these cities which were built for only a limited few? Well, with the right political agency and the right construction environment you can transform an empty space into a breathtaking sight, Exciting right!! I like to think that Architects develop the world, after all they create the foundation which our shopping malls, hospitals, schools and so much more are built on.

Enough harping on about how much I love architects. If you think about it for a second, throughout Africa there is a great need for mixed use developments. It’s an important aspect and this is the reason why I feel that Architecture plays a big role just as much in Africa as everywhere else.

 

The continued population growth across Africa has resulted in increased demand for infrastructure development. This has in return driven a significant rise in the number of investors seeking opportunities. There are companies whose main goal it is to provide exceptional services from conceptual to completion in developing new structures for the prosperity of Africa.

 

A long time ago there was no such thing as big flashy buildings or proper roofing with foundations and pretty things for the eyes. It was simple, traditional architecture. You had a choice of a wooden or a mud house. On the southern coast of Benin in West Africa, for example, there is an entire city built on stilts. These range from churches to banks and even hospitals. I read something once that caught my eye: “I asked him why he wanted a metal roof, and he said, because then I would be somebody.

If you think about it, this way architects have the power to make developments in Africa a source of income for the majority of locals who happen to be young people and are most likely unemployed. If Architects build sturdy structures they are automatically creating employment. By pushing innovation in local materials with skills and craftsmanship based on African heritage, they can actually end up with a mix of development that can benefit the population. Yes, we value our Architects in Africa. If African countries keep growing, it’ll continue to be an exciting place to work as an architect. Just remember, whatever good things we build ends up building us. #ValueOurArchitects

 

I would just like to place emphasis on the importance of proper architecture in the construction industry, after all architecture is the art and science of designing and building large structures. I would like to let you in on a terrible incident that took place in Kenya due to poor consultancy service and planning. In this case Kenya’s lab got a D on their report for this “science project”.

 

In April this year a building collapsed in Nairobi, leaving at least 12 people dead and others injured. The underlying cause and I quote “is poor construction, a problem reflected across the city and many other parts of Kenya”. In Nairobi alone only 42% of the cities buildings are considered safe for inhabitants, according to the 2015 audit by Kenya’s National Construction Authority, the Daily Nation reported and I quote again “developers are bypassing construction rules and regulations in order to meet the demand” said architecture professor Alfred Omenya in an interview after two buildings collapsed last year.

 

So… Consultancy in Africa…..yes, we need you and we don’t want any more buildings collapsing in Africa.

 

Please click on the link to read more about the article of the collapsing buildings in Kenya.

 

Finishing off, I would like to encourage you to check our website at www.l2b.co.za for amazing leads and business opportunities on consultancy. You can also sign up for a free trial to see what we are all about.

 

Until we meet again:)
