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 Las Vegas Bay, and Callville 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A. (IRRIGATION SYSTEM: LINES, HEADS, VALVES, TIMERS, AND PVB) Remove and dispose of existing old and outdated irrigation systems and replacing with all new components.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.

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.

C. (REPAIRING/REPLACING CHAIN LINK FENCE and INSTALL NEW CHICKEN WIRE MESH) Replacing old chain link fence, poles, top rails 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 etc. Doors are not closing properly due to the above. The existing fence is approximately 4 feet high. In addition, install all new ½ inch Hardware Cloth galvanized 19-gauge chicken wire mesh around the perimeter of new and existing fence line. The new galvanized mesh needs to be approx. 20 inches high from the ground surface. Contractor will need to use high gauge wire to secure to chain link fence (this galvanized mesh is to keep snake out of the backyards.)

D. (NEW LANDSCAPING MATERIAL) Removing old landscape materials (dirt and rocks approximately ¼ inch – 18 inches in size or smaller. *Bigger boulders may need to be moved and then place back for yard decoration) 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 and not topping or flowing over the street or sidewalk curve lip. 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. Once the new 3/8 minus dirt materials is installed it will need to wet down with water and a plate compacter machine will be used to compact the new material together. 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.

E. (INSTALL NEW RETAINING LANDSCAPE BRICK WALL) Pavestone, Rampart BevF Tan 6 x 16 retaining wall block or equivalent. Liquid Nail Landscape block adhesive or equivalent. 5/8” crushed rock or equivalent base material. The retaining walls shall be constructed in strict accordance with the specifications, recommendations, and instructions of the retaining wall block manufacture. The base of the retaining wall shall be no closer than 4 feet from the existing chain link fencing, but may, depending on the site conditions, be further from the fencing. The retaining wall shall roughly parallel the existing fencing, in straight, as long as practical, runs. Where the retaining walls change direction, all curves shall be uniform and fair. All retaining walls shall be level to within + or – ½ inch from end to end. The top of the walls shall be flat, in one continuous plane. The height of the retaining walls shall be from the base of the slope to the projected level plane of the associated yard. The walls shall be constructed on a level, compacted base of crushed 5/8-inch rock or equivalent fill, roughly 4 to 6 inches in depth and 24 to 28 inches wide. First course of block shall be embedded a minimum of 4 inches below the surrounding grade. The grade at the base of the wall shall not exceed ½ inch per foot of slope away from the wall base. A minimum of 12” of crushed rock shall be placed and compacted immediately behind the wall and separated from the adjacent existing soil by a geotextile fabric. Clean, landscape appropriate fill shall be placed and compacted behind the crushed rock/geotextile fabric, to bring the yards up to a level, smooth, grade. The top course of retaining wall blocks shall be fixed in place with appropriate landscape block adhesive. The top of the wall shall be topped with wall cap block, held in place with landscape adhesive. The yard area behind the retaining wall shall be filled and graded to be smooth, and in plane with the top course of the retaining wall, and to be sloped away from the house for a fall of 6 to 8 inches.

At the conclusion of the work, all excess material, debris, trash, associated with the work shall be roved from the Park, and the site left in a neat and clean manner.
