ADA Lift at Century Center Project changes explanation 5-17-19 <br />Item 1 <br />The existing corridor ceiling elevation is lower than JPR had documented. Therefore, the area of ceiling <br />above the lift needed to be raised to maintain the minimum required ceiling height of 7'-6". This was a <br />field discovery during construction. <br />Item 2 <br />The cut opening for the lift is shown on the design to receive re used brick (from the cut opening) as the <br />new door way returns toothed in. This will be changed to metal stud and painted gyp board with corner <br />guards. This will result in a credit to be used on the other field discovery related changes. <br />Item 3 <br />The 4-layer existing wall that the opening is cut into between the stage and corridor does not have all 4 <br />layers go up to the existing ceiling as shown on the drawings. Therefore, our designed lintel can be <br />smaller. The contractor has provided a lintel that will result in a credit to be used on the other field <br />related changes <br />Item 4 <br />The lintel shown in the drawings above the door to the lift on the corridor side will not work with an <br />angle. It interferes with the required lift clearance. This angle will be changed to a 3/8" thick 3 %" wide <br />plate that needs to have 4" bearing on each end so if opening is 43.25" the plate shall be 51.25" long <br />(field verify) This is not an add or deduct. <br />Item 5 <br />The pilaster shown on the construction drawings is in a different location than in the field. This will <br />require more CMU ground face block than originally bid and supplied. <br />Item 6 <br />Due to the field discovery related changes the opening cut in the existing wall remained open longer <br />than anticipated. In order for the Century Center events to continue to take place the Scott from the <br />Century Center requested a temporary wall be erected until the opening could be closed off with the <br />project scope. <br />Item 7 <br />Due to items 1 and 3 the existing brick wall at corridor and stage had to be extended upward next to the <br />new ceiling opening. <br />Item 8 (if needed) <br />The original project scope had the ceiling in the corridor as well as the can lights and sprinkler heads <br />remaining in their existing positions. Due to item 1 the sprinkler head moving up in this area can no <br />longer provide the required coverage in the newly created alcove at the top of the lift platform so a new <br />head will need to be added. <br />
