Scope of Work for the Demolition and Construction of an Entrance Sign at the Morris Wetland Management District

The Morris Wetland Management District is located at 43875 230th Street, Morris, MN 56267.

The entrance sign is located 55 feet east of the parking lot entrance.

The first phase of this project will consist of the demolition and removal of the existing concrete and metal entrance sign holder. The 1982 concept design of the sign holder to be removed is provided [Exhibit A] only as a representation of the type of construction that might be encountered. The Exhibit A is not meant to represent every condition that might be encountered once demolition begins. No staff currently employed have first hand knowledge of its construction. Exhibit B are photos of the existing sign holder. Demolition will include the removal and proper disposal, off site, of all materials from the old sign holder.

The second phase will be site preparation, if needed after demolition, and then construction of the new entrance sign holder. Construction will be roughly within the same footprint of the existing one and orientated 90 degrees in relationship to 230th street. Exhibit C is the engineered drawings from a different National Wildlife Refuge’s entrance sign project. The Exhibit C is a template to be used to guide construction decisions of the new entrance sign (note additional engineered design drawing details may become available). The style of sign that the Morris District has is different than shown in the Exhibit C and as such the sign frame and anchoring system into the concrete base design will need to be modified. The redesigned base and sign frame will need to hold up to natural conditions of which include wind and water/ice damage as the primary concerns. Prevailing winds are from the West/Northwest, gusting close to 60 miles per hours multiple times a year, and snow cover often lasting 5 months. The existing entrance sign has been in place for 40 years and was in good shape until straight line winds on the 12th of May of 2023 in excess of 90 mph damaged it. The life expectancy of this new entrance sign should meet or exceed that standard. The sign [Exhibit D] is made of aluminum with printing on both sides and must be visible from both directions. It measures 8’x4’x~1/4” and was manufactured by Voss Signs. The exterior veneer over the concrete core will be covered with a manufactured rock that best matches the manufactured rock on the exterior of the office building.

Exhibit E are images of the building’s existing manufactured rock facade. The contractor awarded the bid will submit manufactured rock options to the U.S. Fish and Wildlife Service representative for final concurrence before purchasing. If a granite capstone is used to prevent water/ice infiltration, again the options will be presented to the U.S. Fish and Wildlife Service representative for final concurrence before purchasing. Contractor will place/mount the sign, of which is already on site.

Post construction the area will be back filled and compacted, as needed, to meet the existing grade of the landscaping. While demolition and construction is occurring, care should be taken to minimize rutting of the surrounding area. If rutting occurs, the ruts will need to be filled to existing grade with black dirt. Leveling the rutted area by blading, skimming, pushing, piling, etc … are not acceptable as it will negatively impact the prairie restoration. The U.S. Fish and Wildlife Service will be responsible for any revegetation/seeding needed.

In addition to the general guidelines within the Scope of Work, the contractor will be responsible for keeping the parking lot accessible for staff, deliveries and the public during their work.

Short duration (less than ½ hour) are acceptable with prior coordination of timing. All permits, underground locates, flagging, soil erosion mitigation, etc … are the responsibility of the contractor.

Construction can commence after the contract has been awarded and preliminary concept proposal for frame modifications has been submitted and approved. Work should be completed on or before the 1st of August 2024.
