Statement of Work (SOW) / Performance Work Statement (PWS)

This document outlines the scope of work for the reconstruction, repointing, and sealing of four historic well caps at the Ste. Genevieve National Historical Park.

• Project Locations: Jean Baptiste Valle House and Kern House.

• Specific Wells:

  • Jean Baptiste Valle Well: Inspect and repair limestone cap and above-grade limestone wall.
  • Kern House Well #1: Inspect and repair limestone cap and above-grade limestone wall (approx. 3 ft tall).
  • Kern House Well #2: Inspect and repair limestone cap and above-grade clay brick wall (approx. 2.5 ft tall).
  • Kern House Well #3: Inspect and repair split limestone cap and above-grade limestone wall (approx. 2.5 ft tall).

• Dismantling: Carefully remove existing caps. Inspect masonry structure above grade for damage and reuse existing materials where possible, subject to COR approval.

• Reconstruction: Set limestone caps with mortar between the cap and the stone/brick wall.

• Mortar: Type-O, complying with ASTM C270 and ASTM C1714, using Natural Hydraulic Lime (NHL) 3.5 and ASTM C144 sand. Mortar sand must match existing in size, texture, and gradation, and be of a color to match existing mortar.

• Mixing: Cementitious materials and sand to be measured dry and mixed in a clean, mechanical batch mixer. Pointing mortar to be mixed to a damp, unworkable consistency and used within one hour.

• Repointing: Rake out joints to a depth of joint width plus 1/8 inch (3 mm), but not less than required to expose sound mortar. Do not remove unsound mortar more than 2 inches (50 mm) deep without COR direction. Prepare reveals with square backs. Clean joints with low-pressure water spray.

• Application: Apply pointing mortar in layers not greater than 3/8 inch (9 mm), compacting each layer and allowing it to become thumbprint hard before applying the next. Tool joints to match original appearance.

• Curing: Maintain mortar in a thoroughly damp condition for at least 72 consecutive hours.

• Quality Control: Requires an experienced brick masonry repointing firm. A written quality-control program is required. Mockups of repointing are required for aesthetic effects and to set quality standards.

• Tools: Only hand chisels, brushes, and other non-powered tools are permitted for removal and application of mortar.

• Place of Performance: Ste. Genevieve National Historical Park, MO.

• Period of Performance: Not explicitly stated in this document, but temperature requirements (40-95 degrees F) suggest work will occur during suitable weather conditions.

• Temperature: Maintain wall temperature between 40 and 95 degrees F. Repoint in the shade to slow drying.

• COR Notification: Notify the Contracting Officer's Representative (COR) of unforeseen detrimental conditions.

• Cleaning: Final cleaning of repointed masonry should be done with a stiff natural bristle or nylon brush after mortar has dried but before it is set. Avoid aggressive cleaning methods.

This document is a template for reporting on the "Limitations on Subcontracting" requirement. It is designed to be used by prime contractors to report on their subcontracting activities, particularly for contracts with set-aside requirements.

• Contract Information: Fields for Contract Number (PIID), Type of Set-Aside, and Total Contract Value.
• Performance Period: Dates for which the report is being submitted.
• Subcontractor Reporting: Sections to detail amounts paid to Similarly Situated Subcontractors (SSS) and Non-Similarly Situated Subcontractors (NSS).
• Calculation: A formula is provided to calculate the "Limitation on Subcontracting Percentage," though it currently shows a #DIV/0! error, indicating it requires data input.
• Template Structure: The template includes placeholders like [Insert PIID], [Insert Type of Set-Aside], [Insert Date], and [Insert SSS/NSS Name] which must be filled in by the contractor.

Bidders should use this template to understand the reporting requirements for subcontracting limitations. It highlights the need to track payments to different types of subcontractors and calculate the percentage of work performed by the prime versus subcontractors. This information is crucial for ensuring compliance with small business subcontracting goals and may influence how a bidder structures their subcontracting plan.
