The purpose of my post was to notify people that the presentation existed and to summarise what was in it so they could decide whether it was worth reading. I threw in a quick and flip comment at the end (i.e. Shocking). It was not meant to be a critical analysis. I don't think they are being...

Now that I have a bit more time. I am up for 'this'. Although this might not be the right thread for Crazy Regional Mobility, so I defer to the senior members / mods. Today the Jan 15 2014 MassDot public meeting presentation was released. It is a very useful document because it outlines the...

This is a great point which I have seen mentioned at other blogs as well. If you have any confidence in the theory that coordinated planning can deliver improved outcomes or even just serve as a basis for consensus decision-making then I agree that this approach is an important one to take...

Except this case was a cut and cover tunnel in alluvial sands and gravels. The failure appears to have been caused by over-dewatering given the permeability of the sands. The high groundwater levels is something more in common with Boston.

I completely agree. Particularly with respect to "deep boring is only possible when you have bedrock to bore through". This statement is simply wrong. I notice lots of comments around these forums, like this one, that suggest that various forms of tunnelling are 'impossible'. There are...

Although I have limited experience bicycling in Quincy, I would strongly support the need for this plan. I found biking through this city to be a frightening and confusing experience. I found quite a lot of downright hostility from drivers as compared to other cities in the region. And no clear...

Correct, bridges have much larger live loads relative to dead loads and far more cyclic loading. But more importantly infrastructure is exposed to weather - particularly salts in snow country. But steel has very similar problems. Preventive maintenance, protection from weather and proper...

It's typically slower, but not by an appreciable amount for a project that will end up taking 16 to 24 months to complete. As always it is probably not going to govern the structural design choice in this case and a proper answer would require additional assumptions – i.e. office / residential...

I think you are moving off topic. We can agree that there are lots of places to draw inspiration from. I respectfully suggest you offer a suggestion for what to do with FH/QM, the inspiration you are drawing from (if appropriate), and the reasons you think it's a good idea.

No doubt I’m not as clever at punnery as you are. However, I read this part of the article: “The outdoor programming … is part of [the new owner’s] larger revitalization plans for the center, which also include building alterations and improvements, and bringing in new retailers” and further...

Thank you for posting these, it is a useful reference. I am familiar with these techniques. I am a former practicing structural engineer. Flat slabs can save depth - in this case residential, light loads, [short spans?], single floor penetrations, no future flexibility, means that you don’t...

Let's keep in mind the source for this is a Reinforced Concrete industry group. I would not rely too heavily on this approach. If you are looking at a 12" to 24" difference in your framing depth per floor you need a different design alternative. I reiterate what I said in my previous post. To...

I've just returned from New York where, for a variety of reasons, I visited Chelsea Market 3 separate times. I think this is a great space to emulate. The food options showcase regional output, they are far more interesting than Faneuil Hall. It's mixed use with offices above. It serves both...

FWIW, I would basically agree with you. Minimum heights would certainly limit what could be accomplished by reducing structural depth. But both the choice of floor system and framing efficiency is far more likely to be governed by other considerations (e.g. spans, efficiency, construction...

Re: Charles River Skatepark I think it's a lovely park with pleasant views. It's near enough for workers to enjoy during lunch breaks. Rather less so when the path is blocked by 2-4 skaters and the noise of shredding on curbs. It seems a poor trade-off to me. But to each his own. If others...

Re: Charles River Skatepark Not to go all 'get those kids off my lawn'. But does this mean they will voluntarily or forcibly leave the Nashua Street Park.

Re: Pier 4 Residential Tower | 136-146 Northern Avenue | Seaport There would be higher design wind loads on the coast but the coast is defined for many miles inshore. The gust factor for components and cladding would be somewhat higher but this would not impact the lateral system. There is...
