What sort of range (%) would be expected of the total cost of construction to do layout, topo all before and after surfaces for quantities (borrow and embankments), calc and document the quantities for payment, checks for final neat lines, and as built the finish project for a dam with structures and bypass road. The project is short duration (3 months) and would probably be full time for one surveyor with GPS, robotic and digital level. There would be some part time for a second crew member in the field. The project is out of town at 9000 feet elevation. I'm the nearest guy (10 miles) by at least 50 miles. I have the right experience.
Need to give a lump sum price, have something about worked out, just wondering if it's in the zone. Estimate of total project construction cost is in the $2 million range.
If you need one and one half crew daily, mult by your daily rate. Use 3 1/2 months for your time. You will probably be as-builting after construction completed. Assume office time to be 1/2 field time.
I would recommend reading the requirements on the as-builts carefully, I worked on a site that required extensive as-builting during the construction path and it just about required a dedicated crew. Maybe 2 robotic total stations for if they need lay out and as-builts at the same time would be the way to go.
I do not have a lot of experience running quantities but would that need to be time verified like when the inspector needs to count trucks?
Surprised no one has jumped in here to recommend scanning yet.
Anybody got experience with a Trimble S6 and the reflectorless scanning routine. One shot on the embankment about every 10 feet or so would be plenty, the specs call for 50 foot X sections but say terrain modelling is also OK.
2% to 2.5% is on the higher end. Even at that the contractor is thinking it is cheaper to hire in-house surveyors.
Thanks for the response. I thought that was about right.
Lump Sums are always tricky. You don't know how or in what order the contractor is going to do the work. It can make a big difference in the amount of survey work required. At this location what would be a 2 hour stakeout (required immediately) pretty much is going to use up the whole day.

I do agree with you.Lump Sums always tricky. Good thought. 🙂
