How to Choose a Building Contractor in Zimbabwe

Choosing a building contractor is the single decision with the greatest effect on your construction project. A good contractor with a realistic scope and a reasonable price will deliver a house. A poor contractor with the same scope and a lower price will leave you with a dispute, a half-built structure, or a completed house full of defects that cost more to fix than they would have to avoid.

Most of what goes wrong on Zimbabwean residential builds is predictable before work starts. The 2019 Zimbabwe construction industry research cited "lowest bidding procurement procedures" as a top cause of cost overruns. A separate peer-reviewed study by Moyo and Chigara published in 2022 found that poor site management by contractors was a consistent factor in project cost and time overruns across Zimbabwe. Both studies point to the same conclusion: who you appoint matters more than what they initially charge.

This article covers what to evaluate before making the appointment: documentation, references, site visits to completed work, and how to read and compare quotations properly.

What You Are Actually Evaluating

A contractor selection is not just a price comparison. You are evaluating four things simultaneously:

Capacity: Can this contractor actually build what you need, at the size and specification you have specified, with the team and resources they currently have?

Track record: Have they built houses similar to yours, recently, to a standard their previous clients are satisfied with?

Compliance: Are they a legitimately registered, tax-compliant business with workers properly covered in case of a site accident?

Communication: Do they respond clearly, promptly and specifically during the quotation stage? The quality of communication before a contract is signed reliably predicts the quality of communication during construction.

These four things are not equally visible in a quotation document. Price is the most visible element and the least informative on its own.

Documentation Worth Requesting

Before appointing any contractor for a residential build in Zimbabwe, request the following documents. A contractor who cannot produce them, or who stalls or makes excuses, is providing information about how they operate.

CIFOZ membership

The Construction Industry Federation of Zimbabwe (CIFOZ) is the recognized professional body for construction contractors in Zimbabwe, established in 1915. With more than 1,200 member companies across building, civil engineering and specialist contractor trades, CIFOZ membership is an indicator that a contractor is operating within the recognized structure of the Zimbabwean construction industry.

CIFOZ organizes its members by Division, Category and Classification. Building contractors who handle residential housing, schools and offices sit within the building division. Categories reflect the scale and type of work a contractor is approved to undertake. A contractor registered with CIFOZ can be verified through the federation at cifoz.co.zw.

CIFOZ membership is not a legal requirement for residential work in Zimbabwe. The absence of membership does not make a contractor illegal. But a contractor with CIFOZ membership has undergone a formal process, operates under the federation's rules, and is accountable to an industry body in a way that an entirely unregistered firm is not.

ZIMRA Tax Clearance Certificate (ITF263)

The ITF263 is the Tax Clearance Certificate issued by the Zimbabwe Revenue Authority confirming that a business is compliant with its tax obligations, including registration, submission of returns and payment. The certificate is issued annually, is valid from January to December, and carries an authentication code that allows it to be verified online via ZIMRA's TaRMS system.

A construction contractor doing legitimate business in Zimbabwe should be able to produce a current ITF263. A contractor who cannot is either unregistered with ZIMRA, behind on tax payments, or late on returns. None of these situations is a recommendation.

Ask for the ITF263 and note the authentication code. Verification takes a few minutes and confirms the certificate is genuine.

Company registration documents

A legitimate construction business is registered with the Registrar of Companies. Ask for the company's Certificate of Incorporation (CR6 or equivalent) and confirm the company name matches what appears on the quotation. The CR6 also shows the date of incorporation and the registered directors, which gives you a basic picture of how long the business has existed and who is legally responsible for it. A contractor operating under an unregistered sole proprietorship is not necessarily disqualified, but it limits your legal recourse if the relationship becomes a dispute.

Also confirm the contractor has a functioning business bank account. Payments made to a personal mobile account to an individual, rather than to a registered business account, create risk and complicate any subsequent record of payments made.

How to Use References Properly

Most contractors can produce a client reference. The question is what you do with it.

Ask for the names and contact details of three clients whose houses the contractor completed within the last two years. Specify recently completed work rather than projects from several years ago, because team composition, management approach and quality standards can change over time.

When you contact the references, ask specific questions rather than general ones:

• Was the project completed within the agreed programme?
• Did the final cost match the original quotation, and if not, why did it change?
• Were there defects after completion, and how did the contractor respond to them?
• Would you use this contractor again?

A reference who answers these questions in detail is useful. A reference who says only "yes, they did a good job" is not. Ask to visit the completed property if the reference permits. Seeing the finished work is more informative than any verbal description.

Inspecting Completed Work

A site visit to a completed project tells you more about a contractor than their quotation document. When you visit, look beyond the surface finish and examine the work that reflects the care taken throughout.

Plastering: Run your hand across internal walls. Plaster should be smooth and even. Cracks at corners, around door and window frames, or horizontally across wall faces indicate poorly prepared surfaces, poor mortar mix, rushed curing, or inadequate tie between the plaster and the substrate.

Tiling: Look at floor and wall tiles. Grout lines should be consistent. Tiles should be flush with each other without lippage, where one tile sits noticeably higher than the one next to it. Lippage is the most common sign of tiles laid quickly by insufficiently experienced tilers.

Door and window frames: All doors and windows should open and close smoothly without binding. Frames that are visibly out of plumb or out of square were set in a hurry before the plaster was applied. Misaligned frames are expensive to fix without redoing the plaster.

Paintwork: Check corners, window reveals and skirting edges where a painter's attention to detail is most tested. Runs, misses, colour bleeding under tape and visible brush marks in areas meant to have a smooth finish all indicate paintwork done without adequate preparation or care.

Ring beam and structural elements: Where visible, check for exposed reinforcing steel or concrete cracking in structural elements. These are more serious than surface finish defects and suggest either poor concrete mix proportions or inadequate cover to the reinforcing.

External work: Look at gutters, downpipes and external plastering. Are gutters aligned and draining correctly? Is external plaster applied uniformly, or does it have patches where it was redone? Are the junction details between the roof and walls neatly finished?

None of this requires engineering knowledge. It requires looking carefully at the work and trusting what you see.

Comparing Quotations Without Choosing the Lowest Number

A lower price on a quotation is not a saving if it covers less scope, uses lower-grade materials, or comes from a contractor who cannot deliver what they have priced.

Before comparing prices across quotations, confirm that each quotation covers the same scope. A useful starting point is the checklist in What Should Be in a Construction Quote in Zimbabwe?. Apply it to every quotation received and list the exclusions from each. A quotation that excludes ceiling installation, perimeter wall and external plastering may be significantly cheaper than one that includes all three, but the comparison is not meaningful until the excluded work is priced separately.

Where a common bill of quantities has been issued to all contractors quoting, the comparison is easier because all tenderers are pricing the same quantities. For more on what a BOQ makes possible and its limitations, see BOQ Explained: What a Bill of Quantities Means When Building a House.

Once scope is confirmed to be comparable, a price difference of 10 to 15% between contractors is within the range of reasonable variation in rates and overhead structure. A price difference of 30% or more warrants a detailed explanation. Either the cheaper contractor has omitted something, is using inferior materials, has underestimated quantities, or is buying the job at an unsustainable price with the intention of recovering the difference through variations during the build.

Evaluate the programme alongside the price. A realistic, sequenced programme that reflects the actual construction stages is a sign of a contractor who has thought through the project. A vague statement of "four months" with no stage breakdown is not a programme.

What Communication Before the Contract Tells You

How a contractor communicates during the quotation stage is a preview of how they will communicate during construction. Note:

• Do they respond to queries promptly, or does it take repeated follow-up to get an answer?
• Do they answer specific technical questions clearly, or deflect with generalities?
• Do they visit the site before quoting, or price from a floor plan without seeing the stand?
• Do they ask questions about your brief, or simply issue a number?

A contractor who visits the site, asks relevant questions about the design, and produces a specific, itemised quotation is demonstrating a working method. A contractor who quotes a round number quickly without visiting the site is demonstrating a different one.

A Written Agreement Before Work Starts

Once a contractor is selected, the appointment must be confirmed in a written agreement signed by both parties before any work begins and before any advance payment is made.

The Agreement and Schedule of Conditions of Building Contract Suite, approved by the Institute of Architects of Zimbabwe (IAZ), the Zimbabwe Institute of Quantity Surveyors (ZIQS) and the Construction Industry Federation of Zimbabwe (CIFOZ), is the recognised standard contract form for building work in Zimbabwe. It provides defined terms for scope, payment, variations, defects and dispute resolution. Under this form, an architect serves as the principal agent.

For smaller residential builds where a formal architect-administered contract may not be in place, a written agreement should at minimum cover:

• The agreed scope of work with reference to approved drawings
• The contract price and what it includes and excludes
• The payment schedule linked to verified construction stages
• The procedure for agreeing and pricing variations in writing before they are instructed
• The defects liability period and what it requires of the contractor
• The consequences of failure to complete the work or remedy defects

A quotation document accepted by email is not equivalent to a signed contract. The courts in Zimbabwe have dealt with construction disputes that arose directly from inadequate written agreements. The Prescription Act [Chapter 08:11] gives a client three years to bring a claim, but a clear written contract makes that process significantly more straightforward than relying on verbal understandings.
