micro level planning for a highway project

Hi Sunil

The key to a succesful highway project is the bulk earthworks cut to fill.

Once you have assimilated the engineers earthworks schedule you can then check that the cu anf fill quantities balance.

This will establish the necessity for borrow pits or disposal sites - this is all brought together in the Average Mass haul calculation which determines your haulage output.

The next problem is the haul roads - they may have to be re routed several times to allow for cut to fill.

Drianage on embankments proceed as the embankments are formed - excavation of drain arisings will add to youre earthwork balance.

Drainage on the carriageway is started before the base courses are laid.

Electrics for signage and lighting are set after the edges and kerbing in the verges.

Black top is laid up to wearing course which is laid last of all when the base levels are cleaned.

Then comes the lining and cats eye studs.

The linear tasks have to be planned around structure and tie-ins.

The proper software for all of this is a time - chainage  system such as Tilos or Vico and even PowerProjec v 12 has a time chainage overlay.

Believe me P3 or P6 are not up to it.

Mike,

you forgot about Spider Project that is used in infrastructure projects evrywhere in Russia.

It also has time-chainage reports but we are used to plan projects taking into account resource restrictions. When resources are limited simple time-chainage solutions like those that you suggested do not help.

You know that I don't beieve in manual leveling.

Hi Vladimir

Sorry for the omission - thanks for letting us know the time - chainage capabilities of Spider.

Mike,

time-chainage capabilities of Spider Project were discussed here many times and I thought that you know about them.

I wanted to state that when resources are limited it is still necessary to create traditional project model and apply resource leveling. The result of schedule calculation may be shown as time-location chart, as Gantt chart, as network diagram, etc.  In this case working with time-location chart alone is the same as manual leveling and is not practical.

Hi Mike,

Thanks for your valuable reply.It was very informative.
