It is our understanding that the new beam at the exterior needs to have additional bearing at each end. We have reviewed the limited bearing and recommend adding a Simpson HH4 hanger at each end. We also understand that there is a concern regarding the shear walls where the new windows are being added. We have reviewed the lateral loads and have included our analysis with this memo. If you have any questions please give us a call.
