Drainage is key
All surface areas should be provided sufficient surface slopes & proper sub “underground” drainage and/or preferably both. This is done so water will not stand anywhere and the ground will rapidly dry and soil will firm. Special care may be required to sub-drain any soil touching basement walls, retaining walls and floors.
Excavation safety should be of the utmost importance to people who work in the excavation industry. As experts in ore field we know how potentially dangerous and devastating a trench line or excavation collapse could be. In fact excavation work has a 112% higher fatality rate than general construction. This is why trenching & shoring standards must be met for all excavations deeper than 5 ft this is actually a required by law and depending on your location the standard may be 4 ft. Check with local and state regulations.
I entered into the bidding world 6 years ago, and to be perfectly honest, I was clueless. One thing you learn fast is that people hold their bidding practices tightly, and rightly so! For me it’s taken 6 years to get to some point of uniformity in my bidding practices. Being an employee for 16 years in the earthwork trades you think you have a grasp of cost and the complexities of bidding, but in most cases what you think you know and what you actually know are worlds apart!
“Construction cost estimating is demanding work, no matter what type of construction is involved. But I think estimating earthwork is the hardest of all. Why? Two reasons. First, excavation has more variables and unknowns. You never know what’s under there until you start digging. Second, you have to rely on info from many different sources and some may not be accurate. ” Quote: Estimating Excavation by Deryl Burch
The book Estimating Excavation was the first book I ever read on estimating earthwork and I highly recommend it to all who are thinking about entering our field. The addition I read was published in 1997 and luckily for us, a lot of things have changed…if you’re willing to make the investment!
The first platform to transform my bidding process was Bluebeam. This is a 2D software, but the price point cannot be beat!! The 3D systems available today can cost you $20-$30 thousand dollars or more! Great for the big outfits, but what are us guys in the middle suppose to do? Bluebeam is a great platform to get fairly accurate calculations for earthwork fills and cuts if you understand the basics of earthwork takeoff in the first place. The great part is you can download and use it for free in its basic form, and if you decide you like it you can buy its service for in the hundreds of dollars not thousands! Using the volume calculation tool can save you hours of time on the floor with a tape measure and a sore back. One feature I love is the ability for you to actually lay out a full set of plans and take a photo of the page you need. You can then email yourself the photo and upload it to Bluebeam allowing you to do takeoffs without the hassle of dealing with a full set of plans.
Like many in my field I was resistant to change at first. I was tough the old ways and was quite frankly, afraid to step outside of my comfort zone. It took real life situations to wake me up. If used correctly, this technology gives us valuable time back, saves us money in costly mistakes, and allows us to provide a more professional and well rounded estimate of job costs.
Moving on, we find ourselves in a new world of technology. Every day we read about new advances in earthwork systems and I could write about them for the next year, but why? Let’s cut through the BS as many of us will not be able to afford some, and the rest of us don’t have the time to learn because we’re actually out on the job working.
Barely a day goes by where “something drone” is not mentioned in the news – drones for delivery, drones as the #1 Christmas gift, drone registration.
While the reporting has not always been favorable – drones landing on the White House lawn, delivering contraband to prisons, flying too close to airplanes – the market’s awareness of this new technology is at all time highs.
The value of these systems simply cannot be denied, and with companies like SkyDirt Topo offering affordable, effective and accurate takeoff services, even the little guy can get in on the action. Arial drone service companies are offering flight based calculations for the following and more:
Aerial Drone Topography
Aggregate Stockpile Measurements
Gas & Utility Mapping
Earthwork Cut Fill Volumes
Progress Payment Measurements
Balance Haul Planning
Aerial Site Mapping – As Builds
Construction Site Videos
Asphalt Overlay and Pavement Staging Scenarios
Aerial Inspection Services
Earthwork Production Tracking
Wind Machine Inspection
Solar Farm Inspection
Site Topographic Takeoff Systems
The SPS585 is used to run Trimble SCS900 Site Controller Software. It is the ideal positioning solution for supervisors or construction surveyors.
The SPS585 GNSS Smart Antenna with SCS900 Site Controller Software can be used for:
- Measuring and verifying original ground levels and site features
- Monitoring real-time cut/fill information
- Checking finished grade and laid material thickness against design elevations and tolerances
- Computing progress and material stockpile volumes
- Monitoring, and conducting quality control for earthworks and paving operations
- Assessing as-built measurements and generating high quality reports for approvals and payment
This system can be obtained by the average Joe too! The price tag ranges from 13 thousand to 17 thousand depending on the system you choose. Yes, 13 thousand to 17 thousand sounds like a lot of money, but 13 thousand to 17 thousand in missed material import or export, spread out over even 2 or 3 jobs, can easily make up the cost of this system.
The world is changing and many of us earth work contractors have been slow to change. I get it, it has taken years upon years to master our craft, but I’m here to say that the new technology works! You learn to trust it. I will say this, either we get on board or we will be left behind by companies who do. I for one plan on growing and being on the front lines of technology, I embrace it, I’ve learned the old ways, and now it’s time to learn the new.
As my friend Deas Plant would say, “Just my 0.02”.
