# LINDE R08 | Conceptual Office Refresh Investment Basis **Decision Pack:** LINDE, Arequipa, Peru **Estimate date:** 09 October 2026 **Revision:** R08 **Currency:** USD **Estimate level:** Conceptual investment allowance, based on one proposed interior refresh and unmeasured area proxies. ## Investment **Base investment: USD 75,304.53.** A same-design sensitivity gives **USD 55,869.25–107,520.39** by varying provisional quantities, supplier comparators, productivity and reserve assumptions. This sensitivity is not a probability interval and does not represent alternative designs. The base includes USD 61,669.85 of priced direct scope, USD 3,977.82 for contractor overhead and profit on eligible installation work, USD 1,588.51 for tax on modeled labor and contractor fee, and USD 8,068.34 of owner design-development reserve. Displayed consumer comparators are treated as gross where applicable; no blanket 18% uplift is applied to those amounts. The total uses unrounded inputs; displayed components can differ by USD 0.01. ## Covered scope and quantity basis The estimate covers the assumed furniture and equipment package, custom melamine allowances, bathroom and kitchenette fixtures, selective interior demolition, floor finishes and preparation, partial acoustic ceiling, repainting, limited drywall/backing, lighting and branch-circuit extensions, Cat6A drops and a small rack/switch package, one AC-01 split unit, limited window film/shades and door hardware, two-stage freight, floor protection, closeout labor and basic trade testing. - The input gives **463.855 m²** as an envelope proxy and **415.157 m²** as an interior proxy. Neither is a measured survey or certified takeoff. - The working floor allowance is **394.77 m²** of floating SPC and **20.39 m²** of bathroom tile. Material overage is included separately. Localized leveling is allowed on 20% of the non-tile area. - Painting assumes two coats on walls indexed at 2.5 times the interior floor proxy and two coats on the full ceiling proxy. - Partial mineral acoustic ceiling is allowed over **60 m²** across S07, S11 and S12; the assumed drywall/backing adjustment is **40 m²**. - Lighting assumes 64 surface/ceiling panels, 8 basic circuit extensions using existing raceways and a serviceable existing panel, subject to verification. No photometric design is included. - Data assumes 34 Cat6A workstation drops at a 15 m average route, one 42U rack, one 48-port switch and one 48-port patch panel. Network core, PoE/UPS and AV are outside this scope. - Plumbing assumes 30 m of cold-water route and 18 m of drainage route across the assumed fixture points, with testing before close-up. Routes and tie-ins are not measured. - Two S04 basins are assumed to be retained/rehosted; they are not new purchases. Six other basin positions and six mixers are priced as new. Six non-S04 vanity bases are assumed at 0.60 linear metres each, with six 0.60 x 0.40 m tops; exact elevations, finish, support and cut-outs remain unselected. The seven WC and two urinal positions are priced as replacement allowances. - The 34th S13 task chair is an explicit allowance to match 34 workpoints. No additional S08 chair is assumed because its count is absent. Eight mobile flip-top tables are included at a current comparable price; fulfillment availability remains unconfirmed. - Ten roller shades, 20 m² of film and ten existing door locksets are allowances only. No 85/86 window-count interpretation is used to order openings. - Customs allowances cover 13.8 linear metres of simple joinery across S01/S08/S13, 6 linear metres of a simple S02 feature panel, the 2 m S06 kitchenette and one small S04 top. Final elevations, sizes, finishes and hardware are not selected. ## Sequence and time basis The CEO-reviewed R09 planning sequence is illustrative and uses a provisional Monday–Friday, 8-hour calendar. Its 05-Oct-2026 start and 19-Mar-2027 finish span **960 working hours**, or 120 assumed 8-hour working days (24 provisional 5-day weeks). Those are schedule-duration hours, not person-hours and not a contractual completion date. - **Supply targets:** flooring/finish materials by 03-Nov-2026; electrical and data materials by 10-Nov; HVAC by 17-Nov; custom furniture/millwork by 30-Nov. Glazing design approval is scheduled for 28–29 Oct with delivery from 30-Oct to 16-Nov. These dates are planning targets, not confirmed supplier promises. - **Stage 1:** occupied management/support areas, 13-Nov–30-Dec 2026. - **Stage 2:** pool/reception/shared areas, 31-Dec 2026–08-Mar 2027. - **Final testing and acceptance:** 09–19 Mar 2027. - The cost estimate includes two consolidated freight allowances for staged deliveries. It adds no weekly site-management, standby, finance or escalation charge because no applicable daily/weekly rate or procurement commitment is established. - The estimate contains **798.38 budget person-hours**. R09 has no crew assignments or resource capacity; the field-hour bridge is not divided across its 960 schedule hours. ## Limits and exclusions This is an investment allowance for the stated assumed refresh, not a contractor quotation, measured bill of quantities, construction drawing or authorization to build. Field verify areas, existing conditions, load capacity, routes, access and finish selections before procurement. **Not included:** licensed off-site haul/disposal fees for removed parquet/tile; structural or major slab/substrate repairs; wall or ceiling reconstruction beyond the allowances above; new main electrical panels, feeders or capacity upgrades; fire alarm, sprinkler or life-safety modifications; core network, firewall, Wi-Fi, PoE/UPS, AV or access control; full window, glazing or door replacement; repair/maintenance of uncounted retained HVAC equipment beyond interface checks; existing-condition and MEP capacity surveys; architectural/MEP design coordination and professional certification; authorization/submission fees; retained timber furniture and frame-trim refurbishment; decorative linear/wall-wash fixtures without a measured fixture schedule; taxes on unpriced future taxable packages; staff relocation/storage, temporary office, financing and schedule acceleration. A current local Arequipa licensed disposal fee and debris classification were not established. The estimate includes manual removal/loading assumptions but excludes the off-site disposal charge. That exclusion must be priced locally before any all-in construction authorization. Existing field conditions can also change the assumed electrical panel/raceway reuse, sanitary routes, substrate preparation and ceiling support. R09 UID 76 also schedules refurbishment of retained timber furniture and frame trims. The costing inputs contain no inventory count, dimensions, condition survey, repair standard or finish selection, so this remains an unpriced exclusion rather than zero cost. **Decision use:** use the base and sensitivity to compare the same interior refresh concept. Before purchase or contract, complete measured area/room takeoff, confirm site capacity and routes, verify supplier availability, price approved disposal, and reconcile taxable contract scopes.
