There will be a revision on the E-100 drawing riser diagram and Electrical Section of SOW to be provided before construction begins, for bidding purposes the revision will reflect;

5. What is the intent for the fire suppression system? Is this system to be provided only in the area of the new work or is the intent to bring the entire building up to code. It does not appear that the 2” sprinkler line existing is adequate to supply the new offices.

There is no work to be performed on the fire suppression system; the existing system is to stay in place and no work is to be performed by the contractor.

6. Is it possible to substitute MDSHA standard asphalts used for both State and county highway (Baltimore) paving uses ‘over the counter’ 64.22 and on occasion 70.22 binders.

It has been noticed on plans sheet C-101 that the new asphalt for the DOMOPS Facility 1110 grind & surface and full depth paving’ detail uses an asphalt binder liquid 76.22. This binder liquid, for the most part, is used in asphalt paving of the interstate highways and beltways. It is not an ‘over the counter’ asphalt. It is weather/temperature sensitive and for the most part not a- hand workable asphalt. As this liquid has to be kept warm/hot, local asphalt plants do not keep this binder in stock. This liquid would be stocked for large ‘special’ asphalt orders. In order to pave with the ‘special’ asphalt, the asphalt paving might have to be put on hold until the plant would have enough asphalt orders to justify stocking the 76.22 binder; and in some instances this ‘special’ paving is completed at night.

It is acceptable to substitute Binder 64-22 which is a Maryland State Highway Administration paving standard for the 76-22 binder specified in the C-101 Drawing on the PJMS 142021 Renovate DOMOPS Facility 1110 project.
