Best Estimating and BOQ Software for Quantity Surveyors and Contractors in 2026

The best estimating software for most quantity surveyors and contractors in Tanzania is still a well-built Excel template, used together with a PDF take-off tool such as Bluebeam Revu for measuring from drawings. Firms that price many projects or work from BIM models gain speed and accuracy from dedicated take-off and estimating software such as CostX, Buildsoft Cubit or PlanSwift. The right choice depends on how many bills you produce, what drawings you receive, and whether your clients expect BIM-based quantities.

We price projects from bills of quantities every week, so we see both sides: the BOQs that are a pleasure to price, and the ones with missing items and wrong totals. Software helps, but a careful measurer helps more.

What does estimating software actually do?

Estimating has three steps, and different tools help with each:

1. Take-off: measuring quantities from drawings (areas, lengths, volumes, counts).
2. Bill production: organising those quantities into a bill of quantities with descriptions and units.
3. Pricing: applying rates for materials, labour, plant, overheads and profit.

Excel can do all three by hand. Take-off software speeds up step one and reduces errors. Estimating databases speed up step three.

Which software should you consider?

Check current prices and licence options with each vendor. Most offer free trials.

Excel: still the workhorse

Almost every BOQ in Tanzania ends up in Excel at some point. It is flexible, everyone can open it, and clients can check it. A good template has:

• Separate sheets for each bill (substructure, superstructure, finishes, services, external works).
• Locked formulas so totals cannot be overwritten by mistake.
• A rates sheet linked to the bill, so a change in cement price updates every item.
• A summary sheet that adds provisional sums, contingencies and VAT clearly.

The danger is silent errors. A formula dragged one row too far or a total that misses a section can cost millions. Always have a second person check the arithmetic.

Bluebeam Revu: take-off from PDF drawings

Most drawings now arrive as PDFs. Bluebeam Revu lets you set the scale and then measure areas, lengths and counts directly on screen, with each measurement colour-coded and listed. You can export the quantities to Excel. Contractors also use it for marking up drawings, comparing revisions and checking dimensions.

CostX and Cubit: when take-off and the bill are linked

CostX and Buildsoft Cubit go further: your measurements are linked to the bill. When a revised drawing arrives, you overlay it, see what changed, and the quantities update. CostX also reads BIM models, so it can pull quantities straight from Revit or IFC files.

These tools make sense for QS firms and contractors who price many tenders a year. For someone producing a few bills a year, the licence cost is hard to justify.

PlanSwift: simple on-screen take-off

PlanSwift is quick to learn and suits contractors and trades who want to measure plans fast: floor areas for tiling, wall lengths for blockwork, counts of doors and fittings. It is less suited to full standard-method bills but fine for pricing your own packages.

Do you need BIM for estimating?

On large and international projects, more designers deliver BIM models, and quantities can be extracted automatically. That saves time, but only when the model is complete and modelled with quantities in mind. Missing items in the model mean missing items in the bill. Treat BIM quantities as a starting point and check them.

What about free tools?

• Google Sheets works for shared bills and simple cost plans.
• PDF viewers with measuring tools can handle basic take-off once you set the scale.
• Free trials of Bluebeam, CostX or PlanSwift are a good way to test on a real project before buying.

Tips for better bills, whatever the software

1. Follow a recognised method of measurement consistently.
2. Write clear item descriptions: material, size, finish and location.
3. Use provisional sums only for work that really cannot be measured yet.
4. Number every item so contractors can refer to it.
5. Cross-check totals against a rate per square metre to catch big mistakes.
6. Keep a register of drawing revisions used for each version of the bill.

Quantity surveying as a career and business

Quantity surveyors in Tanzania register with the Architects and Quantity Surveyors Registration Board (AQRB). Software skills, especially Excel, Bluebeam and BIM take-off, make a graduate QS far more employable. Many experienced QSs run small consultancies preparing BOQs, valuations and final accounts for clients, banks and contractors.

Frequently asked questions

What software do quantity surveyors use in Tanzania?

Mostly Excel for bills and pricing, with PDF take-off tools such as Bluebeam. Larger firms use CostX or similar software, especially for BIM projects.

Is Excel good enough for a BOQ?

Yes, for most projects, provided the template is well built, formulas are protected, and someone checks the totals.

What is the best take-off software for a small contractor?

PlanSwift or Bluebeam Revu. Both measure quickly from PDF drawings and export to Excel for pricing.

Can BIM replace the quantity surveyor?

No. BIM can produce quantities, but someone still has to check the model, measure what is missing, describe the work properly and price it.
