DIVISION 1 SHORT FORM GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: Bottom Land Trail, originally constructed in 2003 in an area that was previously agricultural land near Fox Creek, is proposed to be Tallgrass Prairie National Preserve’s only

ABA/ADA accessible trail, providing continual year-round access to visitors. It is located on land privately owned by The Nature Conservatory but operated and maintained by the National Park

Service (NPS) at the south end of the Preserve, situated between St. Anthony’s Cemetery and

Fox Creek, on the north side of 227th Road. A small gravel parking lot with a few benches and a vault toilet building is situated near the trailhead. The trail has an outer loop length of approximately one mile with a middle connector path and multiple wayside signage/viewing locations. At the northwest side of the trail there is a connection to the Fox Creek Trail.

1.2 Work Covered by the Contract Documents:

A. Project Location: Bottom Land Trail within Tallgrass Prairie National Preserve, 227th Road, Strong City, Chase County, Kansas 66869. NW/4 Sec.17 R8E T19S, -96.5519631ᵒW

38.4038788ᵒN. See plan cover sheet for project location map.

B. Work consists of: Construction of an ABA accessible trail via a 5-foot wide, 5-inch thick, concrete slab on top of the existing gravel surface to provide year-round access to visitors.

The existing gravel trail is constantly prone to washouts and poor surface conditions that don’t meet accessibility standards. A majority of the project is within the Fox Creek floodplain and the proposed improvements include realignments to move portions of the trail further away from the Fox Creek streambank. Additional improvements include relocating signs, benches, stone slab seats, bike racks, and paving a portion of the existing aggregate parking lot to provide accessible travel paths to the trailhead and existing restroom facility.

There are multiple paving contract line items for this project: Base Bid, Bid Additive 1, Bid

Additive 2, and Bid Additive 3. See construction plan sheets C2A and C2B for detailed information, summaries are listed as follows:

Base Bid:

Includes paving improvements to the parking lot and seating areas near the trailhead, as well as paving approximately 3,250 LF of trail to create an accessible loop closest to the parking lot and the north trail realignment area near Fox Creek. Improvements also include relocating signs, benches, stone slab seats, tables, and a bike rack.

Bid Additive 1:

Includes paving approximately 720 LF of trail as well as relocating signs, stone slab seats, benches, and the preservation of the existing historic railway drainage culvert.

Page | 4

Bid Additive 2:

Includes paving approximately 370 LF of trail that passes through forested vegetation and will require use of concrete buggies for construction. Improvements also include relocating signs, stone slab seats, and benches.

Bid Additive 3:

Includes paving approximately 360 LF of trail nearest the existing wetland and forested vegetative areas requiring use of concrete buggies for all construction. A portion of the existing trail passes through a wetland area where stone slabs are currently used as the pedestrian crossing, allowing for open drainage between the slabs at grade. The slabs are not ABA accessible and are to be removed to make way for a proposed non-combustible wetland crossing. The proposed construction/disturbance area for the pedestrian crossing is under a tenth of an acre, thus not requiring wetland mitigation activities. Earthwork excavation is proposed to remove the fill that was associated with the original construction of the stone slab crossing, as a result, this location will return to its original surface elevation by widening and flattening out the drainage area that will pass under the proposed crossing.

The proposed crossing shall require the construction of a non-combustible elevated precast concrete boardwalk, approximately 48 feet in length.

C. All work will be performed under a single contract.

D. Period of performance: Work shall be completed within 100 calendar days of the Notice to

Proceed regardless of the number of bid additives included in the contract.

a. Clarification: The Notice to Proceed will be issued with a period of performance that is all inclusive of supply lead times, material deliveries, decommissioning, installation, anticipated average weather days for location, final commissioning, and acceptance of completed work. The contractor will be expected to provide a project schedule with adequate critical path details to ensure all work is completed within the stated calendar days from issuance of the Notice to Proceed. If weather impacts project beyond typical average weather patterns, contractor shall provide documentation in request for additional days.

1.3 Existing Condition Protections:

A. Preservation of Historical and Archeological Fabric:

i. The Historic and Archeological Data Preservation Act of 1974, provides for the preservation of historical and archeological data that might otherwise be lost as the result of alterations to the terrain caused by a federal or federally licensed activity or program.

ii. IF, in connection with operations under this contract, the Contractor, subcontractors, or employees of any of them, discovers, encounters or becomes aware of any possible historical or archeological data, objects or sites of cultural value on the project area, such as historical ruins, graves or grave markers, fossils, or artifacts, the Contractor shall immediately suspend all operations in the vicinity of the discovery and notify the

Contracting Officer immediately, when safe to do so, and follow up in writing within 2 days, giving the location and nature of the findings. No objects of cultural resource value may be removed. Contracting Officer will contact other entities as required.

Page | 5

iii. Where appropriate by reason of discovery, the Contracting Officer may order delays in the time of performance and/or changes in the work. If such delays and/or changes are ordered, the time of performance and contract price shall be adjusted in accordance with Changes clause.

iv. The Contractor will be responsible for protecting the cultural resources within and adjacent to the project area from damage. In addition, the Contractor will be liable for all damage to the cultural resources caused by their actions or the actions of their agents or representatives. The Contractor shall immediately notify the Contracting

Officer or their representative if any damage occurs to any cultural resource and immediately suspend work in the area in which damage has occurred until authorized to proceed.
