Simplified language.
I'd like to introduce to the dear customer the overall concept of the project I lead.
The task that was set to my Design Institute and me as a Project Manager is to perform the research of the pile foundation and further according to the research results to offer at least two possible ways reconstruction of the doc with the cost estimation.
So, we performed the research of both part of piles - above water and below-water.
Verdict: pile foundations of both sides has an unsatisfactory condition.
The concrete of the piles during 50 years of operation underwent pernicious impact of the sea water.
I'd like to draw your attention to the part of the piles continually changes the environment - at the junction of the seawater and air caused by sea waves.
At this place, we can see the intensive wear of the concrete.
So, we've estimated two possible ways around the problem:
- Total disassembling the piles of the doc at one stage and construction the new one
- Partial disassembling with the state-keeping the technological process.

Otis presentation in 1854, New York City.
Ladies and Gentlemen!
My name is Elisha Otis. I'd like to introduce you my new invention - the Elevator.
It is the perfect substitute of conventional stairs, it is much easier for your legs, you can ascent whatever you want, goods, animals, yourself, after all.
You can control it during the movement and stop it every time you want.Just one button - it is very easy to operate.
It allows to free up valuable space, allowing taller building on smaller areas.
I know that you are very concerned about the safety, so I am going to ensure you by my personal example.
I put here reliable braking system which totally eliminates the danger.
Now you can see one rope only which carries all the weight of me and the car.
Please, break it down with the aid of axe...

Control system
Today I am going to describe the control system executed on the gate in the building of the local government garage.
It is composed of three main components:
-the movement detector;
-the sensor that can recognise car's numbers;
-the barrier.
When any car arrives in front the barrier, the movement detector detects movement and sends output current to the video sensor and logic gate.
The video sensor gets the signal and automatically starts recognising the number of the car and comparing it with the allowed numbers in its memory.
If they match, the sensor sends the output current to the logic gate.
The logic gate produces an output current only if it receives both input currents (AND gate).
Sometimes it doesn't work properly and CCTV is essential in this case. Video camera transmits the picture to the monitor of a security guard.

The design solutions
Dear colleagues!
As you know in two days we have to provide design solutions to the Project Manager for the prospective project.
In order to select electrical equipment, making load computation and calculation of relay protection I need to evaluate and quantify all the electrical loads.
Please, send me asap the list of all the electrical consumers, e.g. electric motors, heating systems, air conditional systems and so on.
In case you are uncertain about the precise wattage of the loads, simply add an extra margin.
But please, try not to overdesign, I agree that "belt and braces" is the sensible approach, but not excessively!
Hope to receive your design assignment asap.

The project manager's letter
Dear colleagues, in three days I am going to have a first design meeting with the oil port authority related to the prospective project.
In order to compose the design brief, I need the following information due at the end of the day:
1. Technological department - preliminary drawings of the reconstructed tank №2A.
2. HVAC department - rough sketches of the boiler room (collaborating with the electrical department).
Firstly, before the meeting, my presentation will be issued to certain specialists in customer office in order to the can comment on, and we will make amendments.
Hereby in one week, we will know if we need to go back to drawing board and redesign completely or just refine slightly.
Waiting for your documents.

The electrical supply requirements of my computer
The electrical supply requirements of my computer are:
- alternating current at the voltage 220 volts (V);
- AC supply required frequency is 50 hertz (Hz);
All the electronic devices are very sensitive to the quality of external supply. There are special requirements for consecutive energy supply, that's why I use single-phase uninterruptible source of energy which is composed of:
- rectifier, to transform alternating current (supplied from power grid) to direct current, needed for rechargeable batteries;
- rechargeable batteries;
- inverter, to provide alternating current to the monitor and computer.

I am calling to shops, services and pretending that I need something.
Hello, my fellow Italki users!
I used this method to get some additional practice to speak with native speakers.
And I have to admit it is very difficult to understand what they are talking about in response.
I have just called to Toyota service pretending that I am going to buy new Prius.
The manager understood everything I wanted to say him, but, I understood 10% from his response. Sometimes I was forced to interrupt him and ask him to clarify.
That situation repeats every time I try to call anywhere.
All native speakers speak very fast and they use a lot of verb patterns.
Have you ever faced with this problem, how to develop the skill to catch words? I want to be able to get a job interview in a future.
Can you share your experience?

There are some words that make me really crazy.
It seems like it is beyond my capacity to spell them right and not to mix.
1) acquire
2) acquaint
3) accrue
4) occur
Am I only one have such trouble?
