1 of 5

Activity Schedule included in the RFP, which identifies seasonal and peak-

use periods for park facilities, including but not limited to:

• Soccer Fields (Fields 1–4):

o Fall season: August–November

o Spring season: March–May

As stated in the RFP Instructions and discussed during the pre-bid meeting,

the Contractor is responsible for developing a detailed construction

schedule and phasing plan that identifies which portions of the park will be

temporarily closed during each phase of construction. The proposed phasing

plan shall minimize impacts to scheduled park activities, avoid peak usage

periods where feasible, maintain safe public access, and be coordinated with

and approved by the City prior to implementation.

Temporary closures of specific park areas will be permitted as necessary to

safely complete the work; however, extended or blanket closure of the entire

park is not expected.

2) Does the City of Duluth have a spoil area where the materials

removed/demolished may be deposited?

a. RESPONSE: No. The City of Duluth does not have a designated spoil or

disposal area available for this project. The Contractor shall be responsible

for off-site disposal of all excess or unsuitable materials in accordance with

applicable regulations.

3) It appears the entire parking lot and roadway has either standard curb or header

curb. In areas where header curb exists are we to tie in flush with top header

curb or will overlay of header curb be permitted?

a. RESPONSE: As previously clarified, header curb shall not be overlaid.

Pavement shall be milled as necessary to match existing grades, tie in flush

with the top of header curb, and maintain positive drainage. Care shall be

taken to ensure smooth transitions and compliance with applicable grading

and drainage requirements.

(compacted thickness) of 9.5 mm Superpave Type II hot mix asphalt, placed

in accordance with Section 32 12 16 Asphalt Paving and GDOT Section

400 requirements. A tack coat shall be applied prior to placement, and

smooth transitions shall be provided at all tie-ins including curb lines,

driveways, and adjacent pavement. Overlay limits shall be adjusted in the

field as necessary to maintain positive drainage and existing curb and gutter

function. Milling, if required, shall be performed as needed to receive the

specified overlay thickness while maintaining drainage.
