Questions from floor:

Q: Is access from SHA needed for this project?
A: All necessary R.O.W. has been acquired in accordance with SHA directives. A letter indicating this is attached and made part of this Addendum.
Q: Does the design loading of the temporary support structure include ice impact?
A: The design loads provided are the minimum required by the performance specification, but are not all inclusive. All necessary design loads shall be at the discretion of the engineer. Please refer to the additional clarification regarding design loads in this Addendum.
Q: Can a crane be placed near the southwest corner of the bridge?
A: A crane may be placed, but the embankment must be adequately built up to create a flat surface. A plan or sketch of the proposed embankment must be provided before construction, for review and approval.
Q: Will all environmental permits be secured before Notice to Proceed?
A: Yes. Notice to Proceed will not be granted until all environmental permits have been secured.
Q: What are the MBE/WBE requirements for this project?
A: Since this project is entirely County funded, there are no MBE/WBE requirements.
Q: What type of finish is required for the temporary support structure?
A: Any type of finish may be used, provided the temporary support structure can remain serviceable without maintenance for three years.
Q: Do the siding boards that are required to be removed contain lead paint?
A: Studies have not been performed to determine the presence of lead based paint. As a precaution, siding boards that are to be removed shall be removed in their entirety. Siding boards shall not be cut, burned or abraded during their removal. All waste generated that could have suspect lead paint shall be disposed of in accordance with local, state, and federal regulations with the assumption that they contain lead based paint.
Q: Is it necessary that each vertical support attachment be required to move 1'-6" in any direction?
A: Portions of the temporary support structure must be movable such that under the future rehabilitation contract, the covered bridge can be properly aligned. Please refer to the additional clarification regarding this movement in this Addendum.
Q: Can concrete be utilized as the substructure for the temporary support structure?
A: No, only structural steel and/or timber cribbing shall be utilized for the substructure of the temporary support. The intention is that steel or timber cribbing can be easily removed upon completion of the future rehabilitation contract.
Q: Will the structure need to be stabilized before it is realigned?
A: Under this contract, the temporary support structure, once installed, shall only serve to support the covered bridge in its current position. No realignment or other movement of the structure will be permitted.
Q: Does the 150 calendar day completion time include both the design and construction phases?
A: Yes. Due to the urgent need to complete this project based on the critical condition of the bridge, all work, including design and construction, shall be completed within 150 calendar days.
Q: If a custom fabricated temporary bridge support is utilized, does the Engineer who designs the support need to be pre-approved?
A: No. The only requirement is that the engineer be registered in the State of Maryland and have at least 5 years experience in the design of bridges.
