Summer project: Dumont water crossing

crews smooth the cementmore cement pouringpouring cementEver wonder who would go out to Dumont Dunes in the middle of August, during the day when temperatures are well over 100 degrees? Its not the duners: they ride at night during the summer because of the heat! Its BLM’s operation crew! Because of their hard work, visitors to Dumont Dunes will be able to enter the dunes through a newly-expanded water crossing.

The existing water crossing was one lane. The summer project by BLM's Barstow Field Office expanded it to three lanes this Summer. This will allow a vehicle to be driven in both directions across the water at the same time. Before this expansion, only one vehicle could cross at a time and vehicles had to wait until traffic was clear in the opposite direction. The third lane is not currently in use, but was installed for future use. Expanding the road up to the crossing would be necessary prior to using the third water crossing lane. It is anticipated that in the future it will allow two lanes in the direction of most travel during peak times -- that is, two lanes "in" on Fridays and two lanes "out" on Sundays.

This project was planned and completed with BLM operations employees Mike Trost, Emilio Villegas, Vicki Salazar, Danny Pando, and Harold Thomas. The operations crew had assistance on the day the cement was poured by park rangers John Kavanaugh and Steve Hentges, natural resource specialist Lorenzo Encinas, and geoloist Jamie Livingood.

The project was completed way under budget.

Material costs were:

Forming Materials and Supplies - $1,430

Reinforcing steel - $2,200

Concrete 160 CYs 4,500 PSI $29,600

Backhoe & Operator I have nothing worth adding to this post!! - I have nothing worth adding to this post!! - I have nothing worth adding to this post!! - x2 Days $2,000

Cement Pumper $1,585

Cement Finishing Crew $2,000

Travel $1,800

Labor / BLM funding $9,792

Labor / fee funding $3,392

Total $53,799

To start the project, the existing water crossing was dug out, holes were drilled into the existing crossing, and rebar was placed in the holes. This allows the new crossing to be attached to the existing crossing.

Footings for the new water crossing were dug

Metal had to be laid and tied

Beginning work in the dark using the vehicle headlights to see, the crew was on site for the pouring of the concrete at 5 am. 160 cubic yards of concrete were poured that day!

The concrete was worked into the footings first, and then the pads were poured Crew waits for more concrete to work into the footings pouring more concrete

The completed project: a water crossing to meet our current needs, and with space for future growth.

Finished concrete work for the water crossing Job done!

We are proud of the work our operations crew has shown on this project!

I was thinkin' they would put some water channels under the crossing so the dust wouldn't stick to my tires. :lol:

Well, they did do a great job, and kept it under $54,000.00. :beercheers:

After seeing the crossing totally flooded this weekend, this slab will work out real good for us. :headbang1:

The quantity of water rushing through the crossing eroded big deep channels in many areas. :headbang1:

The slab seemed to hold up. :headbang1:

Everyone actually had to drive out through Little Dumont to get out to the road. :dance:

This wasn't that bad but if it were a holiday weekend there would have been a grip of stuck rigs everywhere. :broke:

If the cement slab was all the way across, we could have driven out on the gravel road.

Now that sounds expensive. :headbang1:

no worries you will be able to make it across i went out today and went through it in a ranger pickup pulling a trailer

was there a drop off at the end of the slab? there was a drop off there a couple weeks back. when i went off the end with my toyhauler, the a$$ end would have dragged if i didnt have the casters on the back. bob had his "window licker" pulling his friend buggy out there. and his trailer dragged off the end too. and since my casters decided to break on the way back from the last trip. cant rely on them this time.

i couldnt see anything as the water is still flowing and i didnt feel any real drop. when i saw a few diesel rigs and a pusher motor home go through along with all the rest of the support equipment for the mercedes thread i started i wasnt to worried about my ranger getting through

Just a quick question...........did they make the river crossing any longer, or did they just match up to the existing concrete?

:beercheers:

Actually it is the same- they matched it, but about 2/3 of the crossing was covered with rock and gravel before. So now it seems much longer now that it is uncovered. :undecided:

Oh and Lynnette informed us that the river crossing will be cleared of all the rock and debris on Friday of this week. :beercheers:

right.....good luck with that one :beercheers:

Actually, in the same email that mentioned clearing the river crossing, didn't Lynnette say the contractor would be grading the road the same day? I'll go back and check but I'm pretty sure she was updating both items...

use your corprate influence :undecided::beercheers:

The road will be getting another layer of grindings this fall. We are second in line for grindings from the I-40 project (we were last in line last time) so we should be getting much better material. If you are looking for a smooth road that you can drive down at 35+ mph you will be disappointed, the biggest reason for the new road surface is dust control. :beercheers: :mc_smiley:
