01 20 00 Price & Payment Procedures
When estimating historic preservation projects (depending on the condition of the existing structure and the owner’s requirements), a 15%−20% contingency or allowance is recommended, regardless of the stage of the drawings.
01 30 00 Administrative Requirements
• Before determining a final cost estimate, it is a good practice to review all the items listed in Subdivision 01 03 00 to make final adjustments for items that may need customizing to specific job conditions.
• Requirements for initial and periodic submittals can represent a significant cost to the General Requirements of a job. Thoroughly check the submittal specifications when estimating a project to determine any costs that should be included.
01 40 00 Quality Requirements
• All projects will require some degree of Quality Control. This cost is not included in the unit cost of construction listed in each division. Depending upon the terms of the contract, the various costs of inspection and testing can be the responsibility of either the owner or the contractor. Be sure to include the required costs in your estimate.
01 50 00 Temporary Facilities and Controls
• Barricades, access roads, safety nets, scaffolding, security, and many more requirements for the execution of a safe project are elements of direct cost. These costs can easily be overlooked when preparing an estimate. When looking through the major classifications of this subdivision, determine which items apply to each division in your estimate.
01 70 00 Execution and Closeout Requirements
• When preparing an estimate, thoroughly read the specifications to determine the requirements for Contract Closeout. Final cleaning, record documentation, operation and maintenance data, warranties and bonds, and spare parts and maintenance materials can all be elements of cost for the completion of a contract. Do not overlook these in your estimate.
