STATEMENT OF WORK: CLEVELAND LLOYD DINOSAUR QUARRY

Project: Cleveland Lloyd Dinosaur Quarry Building Replacement. Jurassic National Monument.

1. Background

The Cleveland Lloyd Dinosaur Quarry, located in Emery County, UT, has been designated as part of the

Jurassic National Monument. The BLM has a requirement to replace two aging quarry shelter buildings with a single building. The quarry shelter buildings were installed in 1975-1976. The site grading and roof drainage of the existing structures has caused drainage flow to concentrate adjacent to the building and leaky drain systems have allowed moisture to infiltrate the quarry area causing damage to the bone bed.

The purposes of this project are to provide protection to the paleontological resource and improve the visitor experience.

2. Scope

The building replacement project will include removal of two existing structures and installation of a 2,080 square foot enclosed building with a single pitch shed style roof to direct rain and melting snow away from the quarry area. The structure’s roof will extend over a 1,440 square foot shaded patio that will be utilized for additional exterior display and interpretive space to improve the visitor experience. In addition to the structure replacement, the ground adjacent to the building will be graded to provide positive drainage away from the building area. Subsurface drainage protection will also be installed to reduce the risk of surface water infiltration in the vicinity of the building. Sidewalks will be rebuilt as needed to provide pedestrian access. Visitor access will be facilitated with an interior walkway along one side of the

building. Two raised platforms accessible from the shaded patio area will also allow a close-up view of the excavation area.

3. Objectives

The purpose of the project is to protect the active quarry area from vandalism and weather. The building project will address drainage deficiencies with the structures and adjacent area that have caused paleontological resource damage. In addition, the new building will improve access to the quarry area for paleontological excavation and enhanced visitor experience.

4. Tasks

Contractor shall furnish all labor, material, equipment, tools, transportation, and supplies necessary to complete the work according to the contract. To summarize, the work would include:

A. Staging of material and equipment.

B. Retention and protection of paleontological resources and existing displays.

C. Demolition/salvage of existing buildings, infrastructure, and materials, including:

a. Removal of existing buildings and viewing platforms.

b. Retention and protection of existing sidewalk, where indicated in project plans.

c. Removal of a portion of existing walkway.

d. Removal of existing retaining walls, sidewalk, and subsurface drainage system.

e. Removal of existing pea gravel and liner from behind buildings.

f. Pea gravel from Item “e.” is to be salvaged for re-use.

g. Retention and protection of existing surface drainage features.

h. Pulling back soils and stockpile for potential reuse.

i. Grading to historical drainages.

j. Grading to create V-ditch and route storm water around and away from Quarry area.

D. Proposed building foundation excavation and installation.

E. Proposed quarry building construction including interior observation walkway and platforms.

F. Completion of exterior retaining walls, concrete slab and sidewalks.

G. Completion of final contouring and grading.

Minor changes and/or additions to the contract plans and specifications include the following:

A. Demolition and construction activities shall be carried out in accordance with Appendix C of the

Cleveland Lloyd Dinosaur Quarry Building Replacement Decision Record (DOI-BLM-UT-G020-

2024-0007-EA).

B. The accessible ramp as shown in the original plans will be omitted from the proposed construction. The sidewalk adjacent to the Northeasterly end of the building will still be included in the project.

C. The covered patio finished elevation will be raised as indicated in the GRADE POINT TABLE included on Drawing C103 R.

D. The walkway on the Northeasterly end of the building will not require stairs and shall be constructed as indicated on Drawing C103 R.

E. The viewing platforms accessible from the covered porch shall be raised to match the grade of the adjacent covered patio. The viewing platforms shall be constructed of similar materials and workmanship to the raised walkway on the opposite side of the building. The viewing platforms shall be constructed with removable railing and grating similar to the raised walkway.

F. Elevations for footings and stem-walls along with the height of the building shall be increased a corresponding amount to the increased elevation of the covered patio as indicated in item “C.”

above.

G. The quarry area shall be protected from runoff from adjacent areas throughout demolition and construction activities.

H. Spoil materials generated during the project shall not be re-used without approval of BLM

Engineer.

I. During demolition, the existing sunken walkway which accesses the northerly building will be removed. The sandstone cladding of the wall shall be carefully removed and retained for future use by the BLM. The sandstone cladding shall be stockpiled on-site at a location approved by the

COR.

All items and labor incidental to completing the work are to be included in the unit bid prices as shown on the Contractors Bid Schedule and will not be paid for separately. Estimates of quantities are provided for comparison to the Contractors estimates only and are to be fully verified by the Contractor.

5. Delivery

All construction materials and supplies will be delivered to the site. The contractor will arrange for delivery, offloading, and storage of materials at the site. Delivery of major items will be coordinated with

BLM to provide lead time to prepare the installation locations.

Access from the parking and storage area to the quarry requires traversing a narrow section of road that may be difficult for large trucks and equipment. The narrow section of road is bounded by a historic decorative wall. The historic wall shall not be removed or disturbed.

6. Government Furnished Property and Services

Paleontological monitoring will be provided by BLM staff or qualified contracted personnel as indicated in Appendix C of the Cleveland Lloyd Dinosaur Quarry Building Replacement Decision Record (DOI-BLM-

UT-G020-2024-0007-EA).

7. Security

Jurassic National Monument is located behind two locked gates. Provision will be made for contractor to have access through the gates. The contractor will be responsible for following Bureau of Land

Management practices to secure the construction location and adjacent facilities. No special security will be necessary for this contract.

8. Place of Performance

Contract to be performed at Jurassic National Monument as shown in the Project Plans. Jurassic National Monument is located on lands administered by the Price Field Office in Emery County, Utah.

9. Period of performance

Contract shall be completed within 365 calendar days from Notice to Proceed. Due to sensitive nature of quarry area, it is necessary to avoid exposure of the fossil bearing soils for an extended period. Exposure will cause unacceptable weathering and degradation of the fossils and the formational matrix material.

No more than 60 days shall transpire between substantial demolition and erection of proposed steel building. If work is to be halted prior to “drying-in” the proposed building, the demolition shall be delayed consistent with this requirement.

If the 60-calendar day limitation between substantial demolition and proposed building construction cannot be met, the Contractor shall be responsible for protection of the quarry area. Protection measures for the quarry area shall be approved by the COR and BLM Paleontologist.

Substantial construction activities are anticipated to begin after unfavorable winter conditions moderate in the Spring. Contractor shall plan to begin demolition and site work no earlier than March 1, 2026. It should be noted that start date may vary pending actual weather conditions. The beginning date for substantial demolition and construction activities shall be approved by COR.
