a. The Contracting Officer and the Contract Specialist whom shall form and administer any resulting construction contract, are remote National Park Service Employees that do not require any trailers onsite to be used as a field office for this project. Construction contractors may elect to establish and erect a Field Office for themselves on site, however, if the construction contractor had no need for a construction trailer/ field office, they are not required to provide one. For example, a contractor may elect to forgo a construction trailer/field office with electrical and hardline hookups if they have other means they prefer such as a vehicle that will create a work environment that is suitable for them to successfully execute the requirement.

a. Disturbance of vegetated areas will be limited. Some parking in the Maintenance Area lot will be made available to the Contractor and additional parking exists in the Malaquite Visitor Center lot approximately 1.5 miles to the south. As indicated in the Drawings, Contractor parking is to be coordinated with the COR and may be required to adjust seasonally based on park needs. Unlike construction staging areas, areas dedicated only to the parking of Contractor vehicles will not need to be fenced. Refer to Drawings sheet G.02 and Project Specifications section 01 1100, Item 1.3 – Contractor Use of Site.

30. As discussed during the site visit, please provide pictures of the roof.
