THE ESTIMATING ANSWER Estimate office partition installation by measuring the defined two non-load-bearing office partitions, separating product allowances from labour and setting out the work sequence and exclusions. This fictional Southampton example uses 7 itemised lines totalling £13,129.99; its exact quantities and rates appear in the paired app PDF. The worked job is two non-load-bearing office partitions in Southampton . The written scope is: Build two non-load-bearing office partitions in an accessible suite, with selected glazing or door openings recorded separately. Its matching itemised example (https://quicklyestimates.com/en-gb/samples/office-partition-installation-estimate/) shows how that description becomes quantities, allowances and a PDF. These figures are fictional inputs for learning the method, so check the real site, specification and supplier or subcontractor costs before quoting. 1. Define the measured job Build two non-load-bearing office partitions in an accessible suite, with selected glazing or door openings recorded separately. Measure partition lengths, heights, ceiling interface and service conflicts. Record the measurements and existing condition in the estimate before turning quantities into line items. The scope should make clear why this is a separate project from a broader renovation or maintenance quote. Measure for this job: Measure partition lengths, heights, ceiling interface and service conflicts. Record the measured basis next to the relevant cost lines, since a room count, fitted length and purchased product quantity may each use a different unit. 2. Build a product and labour schedule Separate framing, board, acoustic fill and door or glazed components. This example has 7 distinct lines, including layout and building review, site protection, framing allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs. Choose before pricing: Separate framing, board, acoustic fill and door or glazed components. Keep a named allowance when the selection is open, and replace it once the actual product and delivery terms are known. 3. Sequence the work and handoffs Agree a layout and building handoff before material procurement. Show which task depends on access, a selected product or another trade. If that dependency is still open, label the price preliminary and identify the information needed before a firm quote. Plan the handoffs: Agree a layout and building handoff before material procurement. State which stage needs access or inspection before the next can begin, especially if a concealed condition might stop the work. 4. Set a change boundary Fire, acoustic or landlord requirements may change specification after review. The example excludes structural work, ventilation relocation or unapproved compliance certification. Record the discovery, agree the revised work and update the estimate before adding it to the job. Change trigger: Fire, acoustic or landlord requirements may change specification after review. If this happens, write down the revised quantity and responsibility before adding an item to the customer estimate. Worked project calculation The paired PDF has 7 cost lines. For example, Framing allowance is 20.7 metres × £110.20 = £2,281.14; Board and acoustic fill allowance is 57.6 sq m × £51.65 = £2,975.04. Each amount is the stated quantity multiplied by its unit rate. Recheck whether a line describes installed work, a material purchase allowance or a distinct visit before changing its quantity. Office partition installation example — GBP, fictional inputs Work item | Quantity | Unit rate | Amount | Layout and building review | 1 lump sum | £312.00 | £312.00 | Site protection | 1 lump sum | £192.00 | £192.00 | Framing allowance | 20.7 metres | £110.20 | £2,281.14 | Board and acoustic fill allowance | 57.6 sq m | £51.65 | £2,975.04 | Partition assembly labour | 55.7 sq m | £103.30 | £5,753.81 | Door opening kit allowance | 2 each | £496.00 | £992.00 | Joint finish and clean-up | 1 lump sum | £624.00 | £624.00 | Illustrative total | £13,129.99 | Adding the 7 exact line amounts gives £13,129.99 . The PDF uses a 0% tax input and no markup solely to display this arithmetic. Decide the appropriate tax, overhead and profit treatment for an actual job; the fictional rates are not local averages or price recommendations. Scope and price boundaries Build two non-load-bearing office partitions in an accessible suite, with selected glazing or door openings recorded separately. Outside this example: No structural work, ventilation relocation or unapproved compliance certification. The role in this brief is commercial contractor. Confirm who supplies the selected products, makes the site safe, removes waste and signs off the work. Where opening up reveals a different condition, document it and issue a revised scope and price rather than silently extending the base estimate. Also check access, drying or curing time, and the client handoff described in the work sequence. Before you send - Measure partition lengths, heights, ceiling interface and service conflicts. - Separate framing, board, acoustic fill and door or glazed components. - Agree a layout and building handoff before material procurement. - Fire, acoustic or landlord requirements may change specification after review.
