DRAINAGE. 
The whole of the buildings, together with surrounding 
pavements and areas, must be drained through the very best 40 
Terra Cotta vitrified drain pipe, discharging at points beyond 
low water mark on the Schuylkill River, and shall be of the 
sizes shown upon the basement, plan, as follows: 
The main pipes commencing at the centre building east 
front and running around each flank to the rear, shall be 
ten (10) inch pipe, from thence to the intersection twelve (12) 
inch pipe, and from the intersection of the twelve inch pipes 
to the low water mark of the Schuylkill River, fifteen (15)

drainage placed, wherever necessary, to thoroughly drain the 
pavements and areas. 
All pipes with their connections must be laid and cemented 
in the most perfect manner, the soil being filled in and 
rammed down solid in the trenches, and all superfluous 
earth removed as already specified. 
In all cases where the new building or its appurtenances 
interferes with or obstructs the present line of sewer from 
the Asylum building, the contractor shall be required to 
construct a new sewer for the Asylum and grounds so that 
the present drainage shall be left in complete and effective 
condition. 41 
In conclusion, the architect considers it due to himself as 
well as to the Department, to impress upon all bidders the 
fact that the buildings above specified are intended to be 
completely and substantially built; and it being impossible 
to specify every particular item of materials and workman- 
ship required, it must be distinctly understood that what- 
ever is necessary to execute the plans and specifications in 
their spirit must be included in the proposal. Therefore no 
allowance will be made for any ignorance on the part of the 
contractor as the work progresses, as the architect will faith- 
fully supply, when asked, all information, written and verbal, 
necessary to a clear and perfect understanding of his design, 
previous to the proposals being made.
