What type of foundations for Cargo containers?

2009-11-14T05:51:38-05:00

Hello Esteemed Engineers,

I am a school director who is building a school for Thai kids in the south of Thailand. I would like to know how what type of foundation I need for cargo containers stacked not more than 2 floors high?

The surface of the land is soil which shall be leveled and rollered. Could I just put in four large concrete blocks at each corner re-enforced with ray bar?

Or can the land be covered with concrete and the containers just layed on top?

Help me please!

Regards

Richard

* how to reduce unwanted sounds
* how to make useful sounds
* using sound as an indication of some other physical property

The art of reducing unwanted sounds is called noise control. Noise control engineers work with engineers in most industries to ensure that their products and processes are quiet. There is also a great deal of work done with the assessment and design of buildings, workplaces, airports, road systems in fact most noise generating or noise sensitive developments. There are many standards and documents stating what levels of performance must be achieved for each condition. The various standards and regulations used in the UK are condensed into The Little Red Book of Acoustics.

The art of producing useful sounds includes the use of ultrasound for medical diagnosis, sonar, and sound reproduction.

A separate and related discipline, audio engineering, is the art of recording and reproducing speech and music for human use.

How do you calculate cross bracing in a roofing system? I am looking at cross bracing rods to reinforce structural framing 1” diameter 50’ x 50’ bay with joists every 5’ OC.

Calculating Energy Costs

2009-05-27T02:14:26-05:00

As every engineer knows, energy calculation is straightforward. The unit of electrical energy is the kilowatt-hour (kWh), found by multiplying the power use (in kilowatts, kW) by the number of hours during which the power is consumed. Multiply that value by the cost per kWh, and you have the total energy cost.

Total energy cost = (Power in watts/1000) × hours operating × cost per kWh

Maxim’s Energy Cost Calculator makes the calculation even easier.

Tips on Using Your Warm Contact List When Networking

2009-03-04T11:27:21-05:00

When you are searching for a job, aside from checking the ads in newspapers, internet and bulletin boards, it is also very helpful to ask for information from the people on your warm contact list.
They can provide you with up-to-date information on the company and position vacancies that are not posted on job ads. At times when they cannot provide you information about the job that you are looking for, they may be able to refer you to a person that they know who might be able to tell you something about the job.
This is called networking. Networking is when you start using your warm list to get information or referrals to their other contacts. Many people are repelled by the thought of networking. Some believe that it is not a reliable source of information about the job. Others say networking is more difficult than following the leads on the ads that are posted in the newspaper, internet or ad boards.
Contrary to such beliefs, networking is not that difficult to do. You may just have to contact or meet some people, and you can get valuable information that can help in your career search. Also, since the people you meet belong to the same industry, they can provide you information about hiring that isn’t advertised and first-hand facts about the company.
You are already networking and you just dont know it. When you have seen an ad in the paper posted by a company you know little of, you ask your friends if they know somebody who works for the company. So even if you are not attracted by the idea of networking, it is still essential when seeking a job. To make networking easier and more productive for you, here are a few tips.

Copper Pipe Brazing?

Is there any cost data on brazing of copper piping instead of solder?

There is not. There is a section of just labor costs for welding different sizes of pipe (22 11 13.44 9200), which would be slightly higher than brazing.

I was going back and verifying some of the numbers between the column heading listed for this topic and it appears that the user selected 10% “General Contractor’s Overhead and Profit” markup does not equate correctly for some of the values? Is there something missing that I simply do not see?

J. Christ! I will save the frustration of not understanding why I need to create a new account with the forum if we already are signed up for COSTWorks and the inability to copy/paste into this forum????

Anyway..
Concrete Formwork:
FORMS IN PLACE, SLAB ON GRADE - Curb forms, wood, 6” to 12” high, on grade, 1 use
SFCA is measured how? Contact area of wood or surface conctact area of slab?
