Finished cover level

[seanandruby]

After being in the game for over 40 years, some jobs have me questioning my built up knowledge and indeed my sanity. I am about to start regulatory brickwork on a hundred, or more manhole covers and god knows how many road gully covers. The 'engineers' have told me to keep each one, either 20ml, or one coarse low, when they have done the road surfacing, the idea is to cut around all the ironworks and then build them to level ??? Why i asked. Incase the surfacing guys damage the lids ( pmsl at this point ). I asked them if they have any idea how much this unnecessary mammoth task will cost. When asked by them how i would do it and explained how,i was met with gazes thus: :p Now i know i am slow on the uptake but have i really had to wait 40 years for them to tell me how a road is really built ??? :laugh: What you reckon Dave? Replies on a postcard with filed edges, so not sharp enough to cut my wrists, to Birmingham pshyciatric unit :;):

Sean! I feel your pain - but there maybe a method to their madness - is the road going to be basecourse and binder only at this stage? If so, flushing the ironworks to binder level at this stage removes the trip risk etc etc

Some estate works we have done they have simply steel road plated over manholes etc, marked them for future building up! Makes machine laying the road much easier I'll tell ya

when i worked on civils we were given a finished datum and it was up to the tar boys to meet that
seems simple eh?

Simple if the surface course is going to be laid within a reasonable timeframe.

No Dave it's from base to finish. I know the modern way is to keep it low to avoid trips, car damage etc; on an housing estate but on an industrial site it seems a lot of work not to mention the cost. If that is what they want then i agree a road plate over openings and the whole lot, brickwork and frame would be easier for both parties. With the restrictions on time for power tools, jack hammers etc: it will involve a large team of guys breaking out. I suspect having worked solely on drainage in massive slabs i am a bit out of touch with the 'modern' approach.
