STATEMENT OF WORK

FOR CMR HARDWOOD REPLACEMENT

RFQ 19SP5026Q0016

1 INTRODUCTION / SUMMARY OF WORK PROJECT

US Embassy Madrid has a requirement for replacement CMR hardwood on ground and 1st floor.

The project will be located at:

Calle de Serrano, 75, 28006 Madrid, Spain

2 BACKGROUND

In April 2026, an inspection visit was carried out at the residence where existing carpet or hardwood flooring is planned to be replaced.

The carpet is glued to the existing terrazzo which is 15mm thick.

The existing hardwood flooring is designed with a multi-Layer tile patchwork parquet (inlaid)comprised of a Layer sandwich that is glued together.

The standard composition of layers is as follows:

• Upper layer, wear layer or use solid wood.

• Middle layer of 6 to 9 mm coniferous wood louver slats, or plywood board that unites the whole.

• The coniferous wood's backside serves to balance the sandwich.

3 SCOPE OF WORK

3.1 PRIOR TO IMPLEMENTATION

3.1.1 . Recommended Site Visit and Survey. The contractor shall research existing conditions and matters that affect the cost or performance of the services. The contractor should attend the scheduled site visit to confirm all measurements and survey the existing layout before submitting the Bill of Materials (BOM) and quotation. The measurements provided are approximate. The U.S. Embassy is not responsible for inaccurate dimensions

3.1.2. Design and Bill of Materials. The contractor must obtain approval for the design, bill of materials to be installed, and all materials provided before beginning prefabrication and installation.

3.1.3. Complete finalized Work Plan including Critical Path Method (CPM) schedule.

3.1.5.1. Activity Hazard Analysis (AHA) with detail specification of the safety plan to be implemented.

3.1.5.2. List of personnel to be approved by the Embassy for the access request.

3.2 IMPLEMENTATION

3.2.1 AREA ISOLATION AND ACCESS RESTRICTION

3.2.1.1 Include protective measures for existing fabricated walls to prevent dust contamination during construction activities."

3.2.1.2 Access Control Plan. The contractor shall provide a plan for isolating and restricting access to the work area.

3.2.1.3 Works must only be carried out by staff with technical knowledge to do so and always complying with the security rules.

3.2.1.4 Storage. The contractor shall transport and store boxes in a horizontal position.

The flooring must acclimate to the installation location in its original packaging for a minimum of 48 hours. Remove the plastic wrapping when work begins.

During storage and installation, maintain the same average temperature and relative humidity as the building where the installation will take place. In most cases, the temperature must be between 18°C and 28°C before and after installation, with humidity between 35% and 65%.

3.2.1.5 Store the parquet on-site, protected from weather conditions, in a cool, well-ventilated, clean, and dry location. Stack materials with space between the wood, floor, and walls. If the floorboards, slats, or panels are wrapped in plastic shrink-wrapping, keep them wrapped until ready for use. If the parquet arrives on a pallet, keep it on the pallet until ready for use.

3.2.1.6 Store varnishes and adhesives in cool, dry locations with temperatures between 13°C and 25°C. Keep them in closed containers, protected from direct sunlight or other sources of heat. Under these conditions, they can be stored for up to 6 months without losing their properties.

BEFORE IMPLEMENTATION

3.2.2 Checking that connections and installations are disconnected, if the owner did this previously.

3.3.2 Worker Safety Information. The contractor shall provide all workers involved in the project with information regarding:

• The location of drop-offs and openings in the floor structure.

• Special characteristics of the work that may affect their safety

• Special characteristics of the work that may affect building occupants

• Special characteristics of the work that may affect roads and installation

3.3.3. Sign-posting and fencing off openings in the floor structure and facades.

3.3.4. Sealing off access to work areas.

3.3.5. Management of waste inside the facilities.

3.3.6. Placement of site fencing and sign-posting elements.

Once the contractor completes these tasks, work will begin on dismantling the flooring. The building will remain closed at all times, even when no work is being carried out. The contractor shall remove the provisional fencing that demarcates the work site only after completing the project.

3.4 DEMOLITION

As general criteria, the demolition will be carried out following by reversing the order of work carried out to construct a new installation, starting from top to bottom, attempting to ensure that the demolition takes place on the same level, and avoiding the presence of individuals located near elements that are being torn down or knocked over. The following basic standards or principles will be used for the demolition work:

3.4.1 All elements that complicate the proper removal of debris will be eliminated and removed.

3.4.2 The demolition process will start on the highest floor and move towards the lowest.

3.4.3 Measures necessary to avoid dust and particles being emitted into adjacent areas will be adopted at all times.

3.4.4 Elements that have been affected by the demolition will be rebuilt or repaired.

3.4.5. Demolition Material Management. The contractor shall manage all demolished materials and must provide a container on-site for the works.

Disconnection of connections Prior to the demolition, installations that may be affected will be disconnected by Embassy personnel and neutralized in order to avoid to risk of electrocution, flooding due to broken pipes, and explosions or poisoning due to gas.

Installation of auxiliary equipment Before beginning demolition, the contractor shall install all necessary auxiliary equipment and collective protection to ensure the demolition is carried out safely and with minimal environmental impact.

Cleaning up and removing hazardous materia/s Before demolition work begins, general work will be carried out to clean, disinfect, and remove materials classified as hazardous according to their European Waste List code. The contractor shall remove existing equipment and machinery that may cause a nuisance or increase demolition work risk.

Recovering reusable material/s

When reusable materials in the work areas present a hazard, the contractor shall install all necessary protection and auxiliary equipment before removing the materials. When removing materials conflicts with project safety, such as banisters, the contractor shall substitute them with appropriate safety equipment before beginning the demolition process.

Demolition process Taking into account the chosen work method, demolition system, machinery, and auxiliary equipment to be used, the following demolition process has been selected:

Manual pneumatic, electric, or hydraulic hammers will be used, together with a specific tool dismantling wood flooring, finishing profiles, and baseboards.

Careful demolition of the existing wooden floor at the lobby and corridor of first floor for reuse, including the proper packing and storage of wooden slabs.

The carpet or wood flooring will be dismantled and removed without destroying the compression layer or weakening the structural component that supports it.

Before proceeding with the dismantling, the openings that access other areas of the building will be sealed with plastic sheeting.

Expansion joints will be installed in the existing passageways. To minimize potential interference with existing flooring, furniture, or wall openings, the parquet should match the current thickness of 14 mm.

3.5 INSTALLATION OF WOOD FLOORING UP TO 14 mm THICK

Installing wood flooring with the same thickness as the currently installed flooring would maintain the finished floor level, reducing the extra work needed to raise the floor level to a minimum.

Once the contractor removes the current flooring and existing base layer, the contractor shall adequately clean the entire surface, removing any element that may impede proper installation of the flooring.

installation of solid wood will be done in two different ways as follows:

Herringbone wood installation: specialized process of laying wooden flooring or decking in a distinctive V-shaped pattern, where rectangular planks are arranged at perpendicular angles to create a zigzag design.

Apply adhesive or prepare fastening system Position planks at precise angles to form herringbone pattern Maintain consistent spacing and alignment Secure each piece using nails, screws, or adhesive as specified Stagger joints to ensure structural integrity

Floating wood floor installation: laying wooden flooring where the planks are not permanently attached to the subfloor. Instead, the flooring "floats" above the substrate, connected only to adjacent planks through a locking system.

Establish starting wall and maintain expansion gap (typically 1/4" to 1/2") Install first row with tongue side facing wall Connect subsequent planks using tongue-and-groove locking system Stagger end joints by minimum specified distance (typically 6-8 inches) Use tapping block and pull bar to ensure tight connections Cut planks as needed to fit around obstacles and at room perimeter

A 2 mm impact protection and acoustic layer will be extended over the clean support, and the selected wood flooring will be installed. The contractor shall carry out installation following the manufacturer's instructions, including the corresponding expansion joints. The contractor shall fill these joints with wood-colored neutral silicone that is highly elastic and durable.

cover profile that will be affixed mechanically.

3.5.5. Joints and Finishing. Joints that meet exterior carpentry are planned to remain visible;

therefore, the contractor shall give special care to their execution. The contractor shall install joints that meet the same type of material with a wood-colored, lacquer-finished aluminum joint cover profile that will be affixed mechanically.

Joints with Other Flooring Types. The contractor shall install joints that meet other types of flooring with one of two types of brass joint cover profiles: when floor levels differ, the contractor shall use terracing; when floors are level, the contractor shall use a smooth profile. The contractor shall affix both types mechanically.

3.5.6. Where the wood flooring meets the stairs on the upper level, the contractor shall use solid wood nosing with the same characteristics as the selected wood flooring.

3.5.7 Where wood flooring meets in corridor and there no baseboard is installed to cover the expansion joint, the contractor shall use the same solution as for exterior carpentry, taking special care with execution and final sealing.

3.5.8. Floating Wood Floor. Interior flooring is comprised of individual smooth-surface wood components, assembled or pre-assembled, that are not drilled to the primary structure and float on a base layer.

3.5.9. The bands must be placed perpendicular to the slats. If the dimensions of the locations surpass certain limits, there must be expansion joints that can absorb the swelling and shrinking movements of this type of flooring. These expansion joints shall be a minimum 10 mm thick.

3.5.10 Perimeter Expansion Joints. Along the entire perimeter, the floating parquet must have expansion joints with a minimum width of 0.15% of the dimension of the enclosure, perpendicular to the direction of installation, with a minimum of 1 cm. The contractor shall also install this joint around all components that cross the parquet and in areas in contact with carpentry components (e.g., doorframes).

3.51 Finishing: The wood flooring must be varnished by the manufacturer at the factory.

Varnish must be for high traffic foot.

Works will be divided into three CLINs:

CLIN 1: area of 2nd floor.

CLIN 2: area of bathroom Ground Floor CLIN 3: After hours budget. 5 hours per 15 days. Total 75 hours after 17:00hr

3.4 AFTER CONSTRUCTION

3.4.1 When all site work is complete, the Contractor's site superintendent shall review all activities and walk the project area with the COR to ensure that the embassy staff is satisfied, and all work items are acceptable. If any items are not completed, they shall be noted and provided to the Contractor to be addressed and completed immediately.

3.4.2 The Contractor shall ensure that, upon demobilization, the site is left in a clean and orderly appearance, equal to or better than prior to start of work.

3.4.3 Unit measurement and evaluation criteria. Square meter of flooring comprises of slats laying on the slab or floating floor, slats attired to the floor slab, or to floating flooring, or wood flooring nailed or glued lo installed strips (fixed or floating), which may or may not include slabs and varnishing, including cutting, debris removal, and cleanup. Step and baseboard cladding will be measured and evaluated by linear meter.

3.4.4 Waste produced while completing the project unit will be handled in compliance with the Management of on-site construction or demolition waste.

3.3.5 Execution control

- Support: local warpage: to be measured with a 20 cm ruler, where deflections of greater than 1mm will not be admissible, regardless of the location and orientation of the ruler. General warpage: to be measured with a 2 m ruler. The following cases are distinguished: glued parquet (showing no more than 5 mm deflection, regardless of the location and orientation of the ruler).

- Floating parquet (showing deflection of no more than 3 mm). Horizontality: to be measured with a 2 m ruler and a level, showing horizontality deviations not greater than 0.5%, regardless of the location and orientation of the ruler.

- Slab: prior to installing any type of wood floor, the moisture content measurement will be less than 2.5%. Slab/floating floor moisture content measurements will be made approximated depth of half the floor's thickness, with 2 cm being the minimum depth in all cases.

- Planking: installing strips, with parallelism between the strips, leveling of each strip (longitudinally), leveling between strips (transversally)Once the sleepers are finished, the strips must be level in both directions [each strip and between strips).
