The Types of Bridges

the main types of bridges with details

Bridges are essential when it comes to passing all kind of gaps/spans for civil engineers so the types of bridges as well. When we have discussed any kind and any types of bridges there can be complications especially with the less experienced civil engineers, even I had confusions in the past, moreover if English is not your native language it can be more confusing. These days I am preparing some documentation about my professional engineering career and I have found these drawings. They are showing clearly the types of the bridges in the simplest way.

The drawing above shows the 4 main types of bridges, even LOADs, SUPPORT and COMPRESSION Points.

The 4 Main Types of Bridges:

  1. Beam Bridges: This type of bridges are mostly chosen also cost effective based on the performance. Can be built in different spans based on the design. Especially chosen for the ease of construction.
  2. Truss Bridges: You will remember them from the western movies, the railroad bridges … 🙂 But be careful about the maintenance part.
  3.  Arch Bridges: Visually my favourite but the foundations need to be firm. Commonly used in the old world by the Roman Empire especially for water transportation, I have seen marvellous stone arch bridges.
  4. Suspension Bridges: If you have to pass long spans this is the type you are going to use but not cost friendly as beam bridges.

The drawing below shows more detailed bridges like floating bridges, bascule bridges and etc.

My main purpose is to make a small base for engineers looking for types of the bridges, at least having an idea about them.

We can use more detailed drawings and bridges but my aim is to keep the list as simple and less confusing as it can be.

The List of Bridges

f jobs, f world

Our F Jobs

how do you fill the “f jobs” ? before continue reading please note it.

when I was surfing on the internet I have seen the image. When I read the bottom part of it, the idea of this article sparkled.

The world is shaping how we are looking on it. I am working for a long time and as a civil engineer working on a project base, I have worked with a variety of people.

There are people who are working in a job that they do not like but simply they have to. But the problem is mostly not about the job the problem is about how we are looking… When I talk with the people who are not happy with their jobs I can clearly realize that they are concentrating on the negative parts of their job, classically a bad manager, hard working conditions, and etc. 

But I have another idea that if you change your point of view and try to look the things differently or care in other ways, your f job will become a fantastic one. This is the magic. 

I can give you an example of myself; I have worked in risky parts of the world; like Afghanistan (Kandahar Airfield) while the war was going on with cruel Taliban. But when I start to tell about my job at there most people are thinking and saying that you seem like you have enjoyed it so much. The fact is after a while I have realised that I am concentrating on the god parts of my job. And believe me, if I concentrate on rocket attacks, working overtime and over time and like quad-tasking, poor internet connection, and many negative things, this duty/job would be a definite f job, not a fantastic experience.  

Let’s go with your noted answer if you read f jobs as fantastic then you are good to go but if you are reading it as the other way I think you need to re-think your approach…

 

2nd Dispute Boards Seminar

Attend to a Dispute Board Hearing

Do you want to attend a Dispute Board Hearing!. Alone, the Dispute Adjudication Boards (DABs) term is frightening the construction professionals…. But now you have a chance to attend to a mock dispute board hearing. 

one of my projects there was millions of dollars (literally) disputed amount that was basically the result of the different point of views to the works executed and of course interpretation of the Contract. But at the end, millions of dollars were on the table waiting for a resolution. I was telling myself “just the total amount of the basic interest rate and man hours spend for the disputed works could start and finish a middle scale construction project”. As a result, I witnessed myself how costly and time-consuming can be for those kinds of unresolvable disputes. 

Last years, I got a chance to attend a training by UAE Society of Engineers  called “Arbitration in Construction under FIDIC Contracts”. In the training, I learnt the fundamentals about disputes, arbitration, boards, and etc.. Moreover main differences between Arbitration and Dispute Adjudication.  But I was curious to see a live Dispute Board Hearing after the training…

Couple of days before I got an invitation mail from Dispute Boards MENA which was calling (me) for 2nd Dispute Borads Mena Seminar. At the end, I will have the chance to attend a Dispute Board Hearing even it is mock. If I would stay in Emirates up to meeting date which I don’t know yet. But if I am around,  I will definitely attend Mock Dispute Board Hearing. 

Besides, as indicated in the programme one-hour Networking will be another advantage of the day for you.

Part of the invitation mail which is self-explanatory: 

The seminar will consist of an introduction to DABs followed by a mock dispute board hearing during where listed DB MENA practitioners will take on the roles of the Contractor, the Engineer and the DAB. Specifically, the Contractor will present his case to the DAB and the Engineer will respond on behalf of the Employer. Having heard both cases, the DAB will give a decision and share the reasons for reaching it.

Details for the Mock Dispute Board Hearing: 

Date: Wednesday 13th April 2016
Time:
6:30pm – 7:00pm – Networking and Refreshments
7:00pm – 8:00pm – Mock DAB Hearing

Dubai Media City

Rents continue to drop in the UAE

These days one of the hot topics we are discussing about  in the UAE is the rents continue to drop in the UAE. As an expat living in the United Arab Emirates (UAE) when somebody asks my advice about Emirates, the first topic is definitely “Rents”.  Yearly rent for a studio was  around 15.000 USD in 2015. So it is a topic to talk…

As an expat living in the United Arab Emirates (UAE) when somebody asks my advice about Emirates, the first topic is definitely “Rents”.  Yearly rent for a studio was  around 15.000 USD in 2015. So it is a topic to talk…

Two years before when the rent increase law(rent cap) which was limiting the rent increases have been taken on hold and the rents hiked all of a sudden more than 15% in some properties in Abu Dhabi and other emirates as well. Everybody was thinking that the rents will continue to hike.

But the sudden decrease in the oil prices showed its effect and rents started to drop (some says maturing :))  at the end of 2015.

But I was not expecting the rent drops would continue in 2016 but to settle down.

First, The news article referring a report “Rents continue to drop as property market matures” at Big 5 website confirms me;

The report, issued by Core UAE, the real estate consultancy affiliated with Savills, compares rental declines in apartments which have been in the range of 5-6 percent in areas such as DIFC Downtown, Dubai Marina and JBR (Jumeirah Beach Residence). Meanwhile, villas have seen declines of 3-12 percent since the beginning of 2015.

Secondly, yesterday a friend of mine, living in the newer part of the city called Reem Island happily told me that; the owner has decreased the rent around 1%. Which makes me write about the topic.

On the other hand, developers continue their projects but you can see a slow down in the new developments which is not good news for me as a construction professional.

India Real Estate Outlook – H1, 2014

Previous days I have seen the report about India Real Estate Outlook – H1, 2014 which have been prepared by Knight Frank India and want to share it with you but due to my busy schedule I just have time.

As a former expat worked in India. I have interest and expectations from India for the future. Even though India have its own dynamics, way of working and many many more …

Lets talk about the Report:
It was the election year and it effected as slow economic growth, inflation, etc. so:
Construction market was less stable.
As a result of elections, market did not want to launch new projects.
The extreme demand will continue in India in my opinion.
As a result of the elections market will gain power again.
And also as far as my observations and discussions with Indians the new President “Modi” has already a positive psychological expectations for the future.

Cloud Based Data Preservation System for Construction Sites

NAS Drive for Construction Flowchart
NAS Drive for Construction Flowchart

The real topic is Cloud  Based Data Preservation System for small and medium size construction sites also I should admit that I have leaded this system to be set-up at my previous job with our IT Guy(s). System have served very well with a short learning curve and absolutely no data have been lost.
This is the introduction report for the system for Higher Management so there is no how-to on technology detailed it is brief summary.
If you want to learn more I will try to reply your questions;

INTRODUCTION
Computers are part of our work environment. But in the world an issue is getting importance day by day; Data preservation and data management. At this article it is gonna be challenge and try to resolve the data preservation and management with basics of cloud storage
WHAT IS CLOUD STORAGE FOR THIS ARTICLE AND WHY
The general definition of cloud storage is; “Cloud storage is a model of networked online storage where data is stored in virtual pools of storage which are generally hosted by third parties.” For our article cloud storage is networking your storage both with Site offices and main office and also with headquarters of SOMA.
In over all the world at site offices especially in road construction internet connection would be problem and unstable internet connection with the effect of online users at the same time effects data transition from/to the main office negative.So for the local data storage devices and synchronization between sites we can work on webular datas as local data or vice-verse.
The main advantage of the Cloud storage is providing users with immediate access to a broad range of resources infrastructure of other branch organization via a web service and use the data like local in a budget solution.
SYSTEM COMPONENTS AND DEFINITIONS
Network-attached storage (NAS)
NAS is file-level computer data storage connected to a computer network providing data access to heterogeneous clients. NAS not only operates as a file server, but is specialized for this task either by its hardware, software, or configuration of those elements. NAS is often made as a computer appliance – a specialized computer built from the ground up for storing and serving files – rather than simply a general purpose computer being used for the role.
The NAS drive that will be selected shall have Raid property and has minimum two hard drives backing up each other simultaneously and the capacity depends on the targeted documentation system.
Network Connected computers with Internet Connection
SYSTEM STRUCTURE
In general all departments computers are attached to the central network as well as NAS drives for all the places. The sync. Directories shall be selected from the selected computers and sync. Settings will be done by IT personnel.
Also at the general view the NAS drives will be connected with each other and transmit data with each other.
System shall be designed as individual clouds. Site branch offices and Main site office will have its own NAS drive that is pre-programmed by the IT technician(s) of company based on the flowchart above.
For the Main HQ even if it is figured as a NAS drive is attached to the network it can be on a server manner or another way that IT Department rely on.

Which One Is Better; 4 Way Stop Vs Roundabout

this is a global question; Which One Is Better; 4 Way Stop Vs Roundabout
I can write lots of thing through the experiments and researches to determine which one is better but there is a fact that Americans are fan of 4 way stop and English are definitely on roundabout side. but lets watch the Mythbusters episode trying to find out the answer… “Which One Is Better; 4 Way Stop Vs Roundabout ”

http://www.youtube.com/watch?v=OvoFjirrgYA

Personally I still feel more relax with 4 way stops than roundabouts which the NY Times article “Roundabouts: Efficient or Annoying?” which can be read at here shows that some are thinking like me.

Last, for low density roads it seems like roundabouts are better (of course with the countries people tend to obey the traffic rules) however depending on the actual traffic flows a 4 way intersection with intelligent traffic lights could be quicker overall for medium or high density roads.
