Series II: Construction Notes and Correspondence

Series II: Construction Notes and Correspondence, 1912-1918, contains correspondence, notes, proposals, memoranda, estimates, auditor's reports, invoices, lists of subcontractors, and information regarding costs for labor, materials, insurance, and cartage. These materials document the progression of work at the construction site, as well as the billing, auditing, and payment of accounts. Construction expenses were closely monitored by auditors, and accounting discrepancies are frequently noted. Letters of Carrère & Hastings, superintendent D.B. Kinch, and Frick secretary F.W. McElroy appear throughout these files. This series also contains one letterpress copybook of Henry Clay Frick's outgoing letters during the construction and furnishing of One East 70th Street.

Arranged alphabetically by correspondent, with the letterpress book filed at the end of the series.
