Yeah, had a feeling that was the case, I want to recommend full size testing as the next step in the research, but it would be good to have an estimated range of expected results. Doesn't matter that much.

I've been carrying out some research on a new cement formulation. For various reasons the test blocks are 50mm cubes. From some reading I've done the size of the test cubes affects the compressive strength results. Is there a standard equation that's used? Can anyone recommend a good piece of...

Also get your hands on the codes of practice the contractor should have used and start quoting them at him. You gave him verbal warnings and you say that your case is weaker because you've no records of them. That's not true. The contractor has an obligation to carry out work that will not...

put telltales on the crack in the garage wall - this will prove that movement is occuring. If you slope is still sliding into the neighbours property then movement is still occuring. Since it's surface movement, repeated topo surveys should prove slippage. Cheaper and more effective than...

funnily enough I used to do a similiar type job myself. Got the job as a secondment though so I'm not much help on interview questions. Who are the interviewers - HR types, management types, contractor types, engineer types? On a project like that in Ireland, there won't be anyone local with...

Does anyone know of any good references for temporary works design. It seems to be a field where nobody writes anything down. I'm looking at a gantry crane for a bridge and I'd like a few guidelines.

What are you designing? You might be better looking at BS 8110 (or if you're feeling really hard working and brave EC2) or the other British Standards for design guidance.

It's better for the bars to be resting against concrete, failing this it's better for the bars to be resting against each other, what you don't want is air beside the bars. Unless you've got a very runny mix and a very small aggregate size the bars should not be too close together without...

I can't help but wonder if you could just cut the steps straight out of the rock face and attach a hand rail. It would look much nicer.

Could you build a standard RC stairwell from the base of the rock face to the top, similiar to what you'd do in a new tall concrete building. You could then tie it back into the rock face at intervals to give it additional support, but you could do this from inside the stairwell - ie a safer...

Where are you based, there's no point buying a UK book if you're in the US and vice versa. Also, who are you working for, do you need a book that just deals with the EU standards, and does them in depth or do you need a book that covers BS8110 and the EU standards?

finish the interview, show them around the office, introduce them to people, go for coffee with them, and just chat. get them to relax, in a formal interview setting you'll get the "perfect personality" You'll still get the on show aspect if you go for coffee but they'll be a bit less on edge.

It's just structural dynamics, but it's coming up in plastic analysis. Is "formulas for Stress and Strain" on this site or do I google it or what?

Does anyone know of a site where I can get a reference for the stiffness (k) values of simple structures - propped cantilevers, single bay fixed fixed frames, double bay, double storey and the like. I'm trying to analyse simple problems but they all start with needing to know the stiffness...

The problem is with trying to apply free market economics to the energy situation. Firstly oil, pretty much the number one choice for energy, is not supplied by companies and countries operating on free market practices. Secondly the whole price is not applied to most forms of energy. The cost...

It strikes me that what's really missing with Hurricane Katrina is both management and leadership. The leaders said to evacuate the city but a lack of management meant that there was no government effort to evacuate those without their own transportation. To me that's incredible. A good leader...

I am currently under a large amount of pressure to get out a "preliminary" version of the drawing that you are working on right now. I understand that it may have some issues at this time; but I just need to get them a copy. At that time, we can work on finishing the drawing / fixing the errors...

(However, I have found that most of the metal merchants in my region have very limited stocks.) You have to go to the specialist dealers, the ones that sell sky hook always have a large supply of unobtainium in stock.

ah but they'd be in tension, off the skyhook you see.
