Scope of Project

Channel Coast District – El Capitan State Beach Curb and Pavement Maintenance Project

A. Project Background Information:

1. This project site is the main day use parking lot at El Capitan State Beach. It will involve installing asphalt curbs, slurry sealing, painting the parking lot white lines, ADA spaces, crosswalks, and crosshatched areas.

2. This project will be conducted through a public works contract. The hired contractor will be responsible for all equipment and operators necessary to accomplish and ensure all job site safety that may be necessary to meet the requirements of Cal OSHA.

3. All materials provided and installed by the contractor will be of new quality.

B. SCOPE OF WORK

Paving project located at El Capitan State Beach, Goleta, CA.

Main Day Use Area

Section A (Base Bid) Slurry Seal, and paint parking spots, crosswalks, and crosshatched areas. This area measures approximately 56,807 sq. ft.

Alternate 1 if funding is available;

Slurry Seal. This area measures approximately 8,113 sq. ft.

Alternate 2 Slurry Seal. This area measures approximately 26,280 sq. ft.

Alternate 3 Installing asphalt curbs, approximately 534 liner feet

General specifications for cutting, patching slurry sealing of entrance roads and parking lot areas:

• Contractor shall be responsible for traffic monitoring, and allow no pedestrians or bikes on the area. Ensure that the slurry surfacing has had adequate time to cure prior to reopening to traffic -very often drivers assume that the slurry surfacing is drivable despite of the warning signs and cause damage to the fresh placed treatment

• Surface preparation shall include sweeping or high pressure washing loose sand, dirt, dust, and removal of thermo-plastic markings, vegetation, water, or other foreign material from existing paved surface prior to repairs and slurry seal.

• Cover utility inlets with heavy paper or roofing felt

• Contractor will re-strip / paint, parking spaces, ada parking spots, and other markings (stop, directional arrows, cross walks, and crosshatched areas) with durable thermo-plastic traffic paint, matching the layout of the roads and parking lots before repairs. All ADA parking space striping and paths of travel shall meet shall meet current ADA regulations

• Any broken or missing wheel stops will be replaced as part of this project

• Machine blow and sweep clean the entire surface before striping and before opening up to the public

Monitoring: A State Representative and or State Park Archeologist may be on sight for any ground disturbance. In the event of any significant findings, all work shall cease until State Parks Archeologist determine ground disturbance may continue.

Staging: Staging and storage area for equipment and materials shall be coordinated with the State representative. Staged equipment must have 4 mil plastic sheeting or greater under it at all times. The staging area will be returned to its pre-construction activity condition before the job will be considered fully completed.

Hours of Operation: Contractor shall begin work no earlier than 7:00 am and shall halt no later than 5pm. Monday- Friday, unless directed by State representative. No work shall be done on a state holiday unless coordinated with state representative

Warranty: The contractor shall provide 1 year warranty on all work.

2. Breakdown and intermediate compaction before surface temperature drops below 200 deg F.

3. Finish compaction before surface temperature drops below 140 deg F.

4. Regulate paver machine speed to obtain smooth, continuous surface free of pulls and tears in asphalt-paving mat.

B. Place paving in consecutive strips one-half of the roadway width but not less than 10 feet wide unless infill edge strips of a lesser width are required.

Section 321216 – Page 7

C. Promptly correct surface irregularities in paving course behind paver. Use suitable hand tools to remove excess material forming high spots. Fill depressions with hot-mix asphalt to prevent segregation of mix; use suitable hand tools to smooth surface.

3.6 COMPACTION

A. General: Begin compaction as soon as placed hot-mix paving will bear roller weight without excessive displacement. Compact hot-mix paving with hot, hand tampers or vibratory-plate compactors in areas inaccessible to rollers.

1. Complete compaction before mix temperature cools to 185 deg F.

B. Breakdown Rolling: Complete breakdown or initial rolling immediately after rolling joints and outside edge. Examine surface immediately after breakdown rolling for indicated crown, grade, and smoothness. Correct laydown and rolling operations to comply with requirements.

C. Intermediate Rolling: Begin intermediate rolling immediately after breakdown rolling while hot-mix asphalt is still hot enough to achieve specified density. Continue rolling until hot-mix asphalt course has been uniformly compacted to the following density:

1. Average Density: 92 percent of reference maximum theoretical density according to ASTM D 2041, but not less than 90 percent nor greater than 96 percent.

D. Finish Rolling: Finish roll paved surfaces to remove roller marks while hot-mix asphalt is still warm.

E. Protection: After final rolling, do not permit vehicular traffic on pavement until it has cooled and hardened.

F. Erect barricades to protect paving from traffic until mixture has cooled enough not to become marked.

3.7 INSTALLATION TOLERANCES

A. Thickness: Compact each course to produce the thickness indicated within the following tolerances:

1. Base Course: Plus or minus 1/2 inch.

2. Surface Course: Plus 1/4 inch, no minus.

Section 321216 – Page 8

B. Surface Smoothness: Compact each course to produce a surface smoothness within the following tolerances as determined by using a 10-footstraightedge applied transversely or longitudinally to paved areas:

1. Base Course: 1/4 inch

2. Surface Course: 1/8 inch

3.8 PAVEMENT MARKING

A. General: Pavement marking shall include new in-kind striping for all existing and/or new pavement or at locations shown on the plans or stripping that will be removed or covered due to new improvements.

B. Allow asphalt paving to cure for a minimum of 30 days prior to application of pavement markings.

C. Do not apply pavement-marking paint until layout, colors, and placement have been verified with State Representative.

D. Sweep and clean surface to eliminate loose material and dust.

E. Apply paint with mechanical equipment to produce pavement markings, of equal dimension of existing, with uniform, straight edges. Apply at manufacturer's recommended rates to provide a minimum wet film thickness of 15 mils.

1. Broadcast glass spheres uniformly into wet pavement markings at a rate of 6 lb/gal.
