DIVISION 1 GENERAL REQUIREMENTS

SECTION 01110 SUMMARY OF WORK

1.1 DESCRIPTION

The project is located at Lake Mead National Recreation Area. The locations inside the park are Boulder Beach and Las Vegas Bay Housing Area.

The work covered by this contract consists of, but not limited to;

A. (IRRIGATION SYSTEM: LINES, HEADS, VALVES, TIMERS, AND PVB) Remove and dispose of existing old and outdated irrigation systems and replacing with all new components. This includes removing the irrigation control valves, control boxes, existing backflow devices, irrigation water lines, bubbler heads etc. The old system will need to be remove from the project site and legally dispose of them into a landfill or incinerator outside the park. The new system will be mostly above ground system. (beside the water lines going to each tree/brush) (Example - Pictures #1 and #2 in the specs) to have a better understanding.

1. The new pressure vacuum breaker (PVB) will be brass and will have two shut off valves on the device and union coupling on each end for replacement in the future.

(Picture #1 has an example) This new PVB is a testable device that will need to be tested/check annual by our Utility Branch here at Lake Mead. The PVB will need to be installed 12 inches minimum above the highest sprinkler head/bubbler head in use. This new PVB will need to have a control box over it. The control box will need to removal and secure in a way that the wind does not blow it away.) All pipes before and after the PVB will be insulated for below freezing temperatures.

(ONLY THE PIPES THAT ARE ABOVE GROUND)

2. All new irrigation lines leading out of the control box will be ¾ inch PVC (polyvinyl chloride pipe –color white – “schedule 40”). This includes all the fixing that will be used to connect the lines to together. This new line will need to be trench below the ground surface approximately 5 – 6 inches below grade. The new bubbler heads going to each tree/bush will have a ½ inch plastic riser coming out of the ground. The new riser will need to be approximately 4- 5 inches above the ground surface. The new bubbler heads will need to be adjustable to change the water flow to each tree/bush. (example will be in Picture #4 in the specs)

3. The new irrigation control valves will be above ground valves. (example in picture #1 in the specs) These valves will be above ground anti-siphon valves. Must be installed upright and no valve can be located downstream of the antisiphon valve.

The new anti-siphon must be at least 6 inches above the highest sprinkler/bubbler head. These new valves will need to have a control box over it. The control box will need to removal and secure in a way that the wind does not blow it away.

4. The new irrigation control timer will need to be an exterior timer. This timer will need to have an exterior cover plate to protect the control bottoms and screen from the sun UV rays. (example in picture #3) Contractor may use existing irrigation wire (if present) in the old box to wirer new timer. The outlet that is powering the timer will need to have an exterior outlet cover installed. The existing timer does not have this cover. (example #5 in specs)

*NOTE* All irrigation lines and trenches will be inspected by the Contracting Officer Representative (COR) before any lines, fixing, valves, bubbler heads etc. are cover with dirt material. The new irrigation system will be turn on and inspected by the COR of any leaks that might be present before backfilling. The contractor will need to schedule this walkthrough with the COR.

LAKE 225944 Page 3 of 33

B. (REMOVING TREES AND STUMPS) Removing existing and or dead trees around the housing area includes old stumps. The stumps will need to be removed completely or grind below the ground surface. (approximately 4 to 6 inches below grade) The vegetation and debris will need to be remove from the project site and legally dispose of them into a landfill or incinerator outside the park.

Contractor will use dirt material around the work area to back fill the hole to level ground.

The new patio be sloped away from the housing foundation for drainage. The old bricks will need to be remove from the project site and legally dispose of them into a landfill or incinerator outside the park. The new concrete pad will be the same dimensions/measurements of the existing brick patio that is there now.

D. (REPAIRING/REPLACING FENCE) Replacing old chain link fence, poles, and the fence doors that are broken and or damage. Many of the fences in the housing area are broken, rusted though, not in line anymore. Doors are not closing properly due to the above. The existing fence is approximately 4 feet high.

E. (NEW LANDSCAPING MATERIAL) Removing old landscape materials (dirt and rocks approximately

¼ inch in size or smaller) and installing new landscape material. Only about 3-4 inches from the ground surface needs to be removed. New material will be 3/8 minus dirt material. (gold in color.

Match what existing color at Quarters #407 and Quarters #408) Weed barrier fabric will be installed before new dirt material is installed. New material will need to be at least 2 inches deep. The new landscape dirt will be slope/graded away from the housing foundation. The old material will need to be haul outside the park or can be used to help with the sloping around each of the houses before the new material is installed.

Contractor may use the water spigots at each of the houses for the water supply. Each existing tree(s) will have a moat around the whole base of the tree. Contractor will have to remove any weeds, brushes, or vegetation that "may” grow from the schedule site visit to when the contractor receives the notice to proceed from the Contracting Officer.
