A Proposal For The Realignment Of A Road

Do you know what gravel is? Just so we know that you have the basics down.

I would have at least looked up the word "realignment".

Hire a civil engineer to do the work. You obviously have no idea how to even begin.

Welcome to CR4. Hire a civil engineer.

thanx lyn.

i am studying civil engineering doing my last year of study and i know the theoretical aspect of realignment because we did a couple of calculation problems in highway engineering. so i just wanted an insight of what it would involve (practical aspect) and if i am supposed to aggregate software like ArcGIS, AutoCAD and what not for data acquisition, analysis and design.

I will not be able to help you.

The Request For Proposal should spell it what is to be included. I agree with lyn, the fact that you ask this level of question shows that you don't know enough to do the job.

the point is that i am supposed to collect data make a proposal which will be a assessed by expatriates. i have not started anything yet, m meeting up with my project supervisor tomorrow so i thought i can get some guidelines from people who have done anything similar or have ideas as to what it involves.

After you get done with the pretty drawings then comes the hard and expensive part that involves machinery.

(Thats also the only part that the public cares about regarding whether it was done right or not.)

Proposal should state that your offering includes; specifications and drawings and the codes to which you will comply.

Proposal should state that your offering includes (your choice of) the following;

Permits, survey and layout, Materials and equipment to provide compacted sub-base course, compacted base course, compacted surface gravel. Base and sub-base from excavated materials if suitable.

Proposal should list the software to be used and the format of the drawings, originals,, prints, drg. or dxf. files.

Use my lists to trigger your imagination, think what is necessary to do the job and what you would want to receive if you issued the RFPl.

Ahhhh, another student homework project in the works. You DO seriously need to go back and restudy highway engineering design basics Grasshopper.

You do know that road alignments come in 2 major flavors, right? 1. Horizontal alignment, and 2. Vertical alignment.

I suspect that you are not in the USA, correct? Here in the Good 'Ole USA, we CE's use the AASHTO Standards, whether the Civil Engineer works for the Federal, state or local governments, or works for a private consulting engineering firm. I don't know what standards you use in your country, so I cannot go further and spue forth words of more wisdom.

Also, a CAD program is only a tool, so you had better know highway engineering basics first, otherwise you are just wasting your time and efforts plotting out pretty drawings that aren't necessarily constructible.

In what way is the road put of alignment? Too hilly, but the bed is correctly placed? = grader needed if gravel plus steam roller/grader/steam roller etc., to bring to correct grade, adding more gravel, as needed. For a concrete/asphalt road = might involve removing the top surface down to the gravel and then make flat and re-surface it.

If the road follows the wrong path, = possible complete rebuild, with drainage, culverts etc = complex task

First you need to decide where the road will go in the realignment. This will involve surveying the proposed route. Roll out the programs to do proposed vertical and horizontal alignments. Plug in a road profile, calculate volumes of earth moved. You want preferably that cut = fill, so you don't have to borrow or spoil. Easy (in principle).

Firstly if they say a proposal for the realignment of a road, what do they really mean?

The Vogons are coming.

Oooooookay, if you are still in (school), you should be asking your (professor/student assistant/fellow-students-who-did-this-project-last-time) for more specifics about the assignment, like, for whom is such work to be done?; where does it start from, and where's it supposed to go; about how long/short should it be, in what units of measure? is it to be (replace-in-kind) or (widenning)?; is it for conventional, or unconventional, vehicles; are there cost limitations?; what are the (un/acceptable) materials? etc., etc., etc.,...

In other words, you should become more like (Sherlock Holmes) in defining the details of the problem, and eliminating the (illogical) from the (logical)...

If you are not still in school, or are making this effort as part of some work-study program, then you should be asking how did this kind of work last time and what records remain of previous efforts...

Any branch of (Engineering) is all about learning to ask the most relevant questions, first, in order to more clearly define the (problem) to be (solved), right?...
