PROJECT: Hygrothermal Analysis on the DCR LOCATION: No. 17 Swettenham Road, Singapore 248105

S T A T E M E N T O F W O R K

I. BACKGROUND

The U.S. Embassy in Singapore intends to award a contract to conduct a hygrothermal analysis on the Deputy Chief of Mission Residence (DCR). The residence is slated for repair and restoration, as it is currently having issues such as condensation on windows, mold and mildew growth, and damage on wood materials due to termites, all of which threaten its overall habitability. The hygrothermal analysis is essential to help identify the underlying causes and provide recommendations to solve these issues. The DCR is a conserved house that falls under the jurisdiction of the Urban Redevelopment Authority (URA) of Singapore, necessitating a meticulous approach to its repair and restoration.

II. GENERAL

The Contractor shall conduct a hygrothermal analysis and furnish all required personnel, tools of trade, equipment, materials, transportation, insurance, delivery and a competent English-speaking Supervisor who will stay at the job site every workday throughout the execution of the project.

III. LIMITATIONS AND CONSIDERATIONS

The Contractor shall perform the work required of them. The following are the limitations and considerations that the Contractor must take into account while conducting the hygrothermal analysis:

1. The building is a conserved house. Major changes to the façade, architectural, and structural elements are strongly discouraged. Any alterations should only be considered if they are deemed critical for the safety and stability of the building and shall still be subject to approval. Coordinate with the Contracting Officer Representative (COR) and check URA guidelines.

2. Any replacements or restoration of building elements, features, or materials must have the same design, color, and general materials of the original. The architectural style, pattern, and detailing that characterizes the house shall be maintained.

3. The hygrothermal analysis shall be limited to the DCR main house only. Other structures within the compound shall not be included, unless proven to have direct and critical effect to the DCR main house.
