production rate

Dear Min,



It would be interesting to deliver the advice that you want. So here is my reply:



1. The markings that you are talking about are Survey marking. This is usually done by a crew of 2-3 people. The area that they can cover depends on how smooth/ slope is. But I would say that you can cover 2000-4000m2/day.



2. The lighting poles that you descibe can vary in height between 8-50 meters. So you need to be more specific. The poles need a foundation with Anchor Bolts, and the Pole is usually installed with a mobile crane. The rate depends on the area and the preparation available.



So you need to visit the site, and ask your construction crew these questions as well.



With kind regards,



Samer

Consider markings as an activity parallel to earthworks (incidental) with duration determined by the duration of earthworks and any other work that require such markings. This can be modeled with a Hammock activity. It will be a continuous operation in roadworks, not necessarily in other type of construction where it can be intermittent; in road works you need the crew available at any time. The surveying crew will continuously be replacing the markings and with today surveying equipment they should not interfere with the progress of earthworks, if they do send them to the guillotine.



Best regards,

Rafael

Hi Min Joon Sung



Sorry but you are in a world of your own.



The advice that you are requesting has no relevance to any road construction project.



Ask your superior in the team and then put it in the schedule if you can.



Meanwhile follow my maxim - If you can’t build it you can’t plan it.



Best regards

Hi Min Joon Sung



The best form of software for this type of linear project is either Vico or Tylos.



Otherwise you have to split your barchart into manageable chainage slots - preferabble cut chainage and fill chainage



Within each chainage band the following is a typical sequence:



Strip topsoil to storage

Cut - haul to fill

Fill compaction - either using excavated acceptable or imported material.

Under alignment drainage - using arisings for fill.

Cut to formation

Lay sub base and compact

Cut and lay kerbs

Construct alignment manholes

Lay base tarmac and wearing course

Excavate pavement service trenches and lay cables

Erect lighting and signage

Spread stored topsoil and planting

Lay pavement cover

Lay road final cover

Clean and clear.



You will find discussions on productivity rates for cut and fill in this forum when you search on "average mass haul" or M4



Best regards
