In private gardens, revenue arrives project by project: enquiry, site visit, quote, execution, invoice, end. In grounds maintenance, revenue arrives by contract — the same site, the same contact, the same invoice, across twelve months or across three years. For a business owner that changes planning from the ground up: crews can be scheduled reliably, machinery pays for itself over a known term, and the gap between the end of autumn and the start of spring becomes narrower. The route there does not run over the garden fence, though. It runs through property managers, housing associations and public procurement offices — three types of client with three procedures, three sets of documents and three ideas of what a bid must contain. This article describes who awards maintenance work, how a tender runs, what a bill of quantities contains, where money is regularly lost in the calculation — and which part of the groundwork your own website can take over.
Key takeaways
- Grounds maintenance replaces project revenue with contract revenue: an initial term of three years with a renewal option is common and makes crews, machinery and staffing predictable for months ahead (project experience).
- There are three types of client and three routes: property managers request quotes informally, housing associations award framework contracts split into lots, and public authorities run a formal procedure with deadlines and a procurement portal.
- The annual value of a maintenance lot is set not by the unit price but by the number of repetitions per item. Anyone who overlooks the repetitions gets a mowing item wrong sixteen times over, not once (project experience).
- Suitability records decide before price does: tax and social insurance clearance certificates, liability cover, a reference list, proof of qualifications and declarations under state procurement law must exist before a deadline starts running.
- The website does not win a tender; it decides the invitation that comes before it: a dedicated grounds maintenance page, references by property type with area sizes, and a named contact with a direct line rather than a generic contact form.
Why grounds maintenance carries a business differently
The difference between garden construction and grounds maintenance is not a technical one but a commercial one. A terrace project delivers a high contribution margin over three weeks and nothing afterwards. A maintenance contract for a housing estate delivers the same amount every month, but it demands reliability on dates somebody else has set. A business that runs both can treat maintenance as base load and construction as the peak — the crew still drives a known round when a building project is postponed in spring or a permit is missing in summer.
Landscaping in Germany is dominated by small businesses (BGL Bundesverband Garten-, Landschafts- und Sportplatzbau). That size is an advantage in grounds maintenance: a firm with two to four crews can run fixed rounds, keep journeys short and stay personally reachable — three qualities property managers weigh more heavily than any glossy brochure. The drawback lies in price. Maintenance work is more comparable than construction, the items are specified, and in case of doubt the bid price decides. A business that does not know its set-up times signs a miscalculation here for three years.
What predictable revenue means day to day
Who awards the work: three types of client
The most common false assumption is that maintenance work is all awarded in the same way. In reality the routes differ so much that a business needs different documents and a different first contact for each type. Approach a property manager like a procurement office and you look cumbersome. Approach a procurement office like a property manager and you are excluded on formal grounds.
Property managers and owner associations are the way in. What counts here is reachability, short journeys and the willingness to respond at short notice. The decision is often taken by an advisory board, that is, by lay people placing three quotes side by side. Housing associations and cooperatives work with larger portfolios and award in lots, frequently as a framework contract covering several years and several neighbourhoods. Municipalities and other public authorities are bound by procurement law — there the route is prescribed, from the notice text to the deadline for bidder questions.
| Client | How work is awarded | What tips the decision | What to watch |
|---|---|---|---|
| Property manager, owner association | Informal request for quotes, usually three side by side | Reachability, price, impression at the site visit | Clarify who decides: manager, advisory board or owners meeting |
| Housing association, cooperative | Framework contract, split into lots by neighbourhood or trade | Capacity, documentation, response times | Check the size of the lot against your own crew strength |
| Municipality, public sector | Formal procedure with a published notice and deadlines | Formal completeness first, then price or award criteria | Records complete beforehand; deadlines exclude late bids |
| Commercial and industrial sites | Purchasing or facility management asks directly | Punctuality, reachability outside the season too | Winter maintenance is often expected in the same breath |
| Churches, care providers, cemeteries | Direct enquiry, partly through administrative offices | Dependability, restraint in tone, local presence | Respectful conduct and fixed dates before public holidays |
For how a business presents itself, one plain consequence follows: anyone offering grounds maintenance needs a dedicated grounds maintenance page that does not speak the same language as the private garden pages. The board of an owner association looks for dependability and reachability; the procurement office looks for suitability and capacity. The two rarely sit well on the same page.
How public tenders actually run
Public authorities may not simply hand out maintenance work; they have to run a procedure. The principle is set out in the German act against restraints of competition and applies in spirit below the European thresholds as well, where the federal sub-threshold procurement rules and the corresponding state rules apply. What matters for a business is that every procedure is documented: whatever is not submitted on time and in the required form is not evaluated — however well the business happens to know the site.
Public contracts and concessions are awarded in competition and by way of transparent procedures. In doing so, the principles of economy and proportionality are observed.
The line between a national and a Europe-wide procedure is the EU threshold for supply and service contracts. It is reset at regular intervals by the European Commission and differs between central and sub-central authorities, that is, between federal bodies and municipalities (European Commission). Because these values change on a cycle, the figure in force should be looked up before every bid rather than quoted from memory. More relevant in practice is the second rule: public authorities are to take the interests of small and medium-sized firms into account and award work in specialist and partial lots. That is precisely why large maintenance contracts often appear as several smaller lots that a firm with three crews can bid for.
- Open procedure: the contract is published, every suitable business may bid — the normal case for larger maintenance lots
- Restricted procedure with a call for competition: first an application to take part, then an invitation to bid issued to a limited number of suitable businesses
- Negotiated award: the authority approaches selected businesses and may negotiate on content, permitted only in the regulated cases
- Direct award: awarded without a procedure up to a defined value; federal and state rules set that value differently and change it occasionally
- Framework agreement: terms are fixed for a period and individual call-offs follow as required — common for grounds maintenance across larger portfolios
Notices are published on electronic procurement platforms. Municipalities in Lower Saxony generally publish through the state procurement portal, larger cities sometimes additionally on their own pages; Europe-wide procedures also appear in the Official Journal of the European Union. For a business this means a one-off registration, a stored interest profile by service area and region, and a fixed weekly slot when somebody works through the notifications. Anyone who starts looking in spring finds the lots whose deadlines expired over winter.
Why procurement offices open a bidder's website
What a bill of quantities contains
The bill of quantities is the core of every tender. It breaks the upkeep of a site into individual items and gives each item a reference number, a short text, a detailed long text, a quantity, a unit and — the decisive point for maintenance work — the number of repetitions per year. The bidder enters only the unit price. Everything else is given, and that is exactly where the trap lies: overlook the repetitions and you do not calculate one error, you calculate the same error sixteen times.
Technically the schedule usually describes upkeep maintenance, that is, the lasting preservation of a condition. That differs from completion care and establishment care, which fall due after a site has been built and bring about the functional condition in the first place (DIN 18919, vegetation technology in landscaping). This distinction is not paperwork: if a client tenders a young planting as upkeep maintenance although establishment care is still required, the quantities are wrong — that belongs in a bidder question, not in a silent expectation of extra payment.

Annual value = quantity x unit price x repetitions per year.
Provisional items are carried out only after written release and
do not count towards the secured base load.Alongside the items, the tender contains the contract terms: duration, renewal, notice periods, payment terms, rules on price adjustment, contacts on both sides, requirements for documentation and records. These parts are often skimmed, although over three years they move more money than two cents of difference in the square metre price. The rules on additional quantities, on weather-related cancellations and on the postponement of dates deserve particular attention — they determine who carries the risk of a wet spring.
- Repetitions per item and year — the strongest lever on annual value and the most common error when transferring figures into your own calculation
- Disposal of clippings, leaves and green waste: included or paid separately, and if separately, by volume or by weight
- Access, keys, gates and barriers: access times shape the real duration of a round more than the size of the area does
- Provisional items without a guaranteed quantity: they do not belong in the base load and must not carry your fixed costs
- Winter maintenance as a separate lot or as part of the same contract — the boundary decides standby cost and on-call duty
- Documentation duties: a service record per visit, photographic records, an annual inspection walk with minutes
Calculation: where the money is lost
Pricing a maintenance lot is a calculation about area output, set-up time and journeys — not about material prices. Applying a construction calculation to a maintenance lot misses the point. The three figures that count: how many square metres does a crew manage in an hour with the machinery available? How long do loading, driving, setting up and clearing away take per visit? And how often per year does both repeat?
Set-up time per visit
With sixteen mowing passes a year, set-up time falls due sixteen times. Ten minutes more per visit add up to almost half a working day across the year that nobody paid for, unless it sits inside the unit price.
Journeys within the site
A housing estate with eight separate lawn areas is not one area but eight. Edges, bollards, bike racks and washing posts reduce area output considerably compared with an open meadow.
Disposal and green waste
Clippings, leaves and shrub cuttings cost volume, transport and a gate fee. If disposal is not tendered as a separate item, it sits inside the unit price and has to be calculated there.
Weather and date windows
Tight windows before public holidays or events mean overtime or a second crew. If such windows appear in the schedule, they belong in the price rather than in a later discussion.
Traffic safety and barriers
Work on paths, driveways and parking areas requires safeguarding. Shrub and tree work adds inspection duties that tie up qualifications and time — both belong in the price.
Price adjustment over the term
A three-year contract without an adjustment clause ties today's wage costs to the year after next. If the clause is missing from the tender, it belongs in a bidder question.
A second point concerns bidding strategy. It is tempting to price the basic items tightly and rely on provisional items. That rarely works out: provisional items are called off when budget is available, and in the third year of a tight household budget it is not. A sound calculation covers fixed costs from the secured basic items. Anything above that is an addition, not a foundation.
Set the floor before you bid
Proving suitability: the folder before the tender
Public contracts are awarded to competent and capable businesses. What that means in a given case is set by the contracting authority in the tender documents — and it is checked before anyone looks at the price. Experience from bidding processes shows that businesses fail less often on price than on missing or expired documents (project experience). The reason is mundane: only a few weeks lie between the notice and the deadline, and a clearance certificate does not arrive the same day.
- Commercial register extract or trade registration, together with proof of entry in a professional or commercial register
- Clearance certificates from the tax office, the health insurance funds and the employers' liability insurance association, each with a current issue date
- Proof of public liability insurance with the cover amounts required in the tender for personal injury, property damage and financial loss
- A reference list of comparable maintenance work from recent years, stating property type, area size, contract term and a contact
- Details of staff, crew strength and machinery, sometimes as a self-declaration on a prescribed form
- Proof of qualifications where required: plant protection, tree inspection and tree care, chainsaw training, traffic safeguarding on roads
- Declarations under state procurement law, in Lower Saxony under the state pay and procurement act, including declarations for any subcontractors used
This folder belongs on the table once a year, not once per tender. What works in practice is a binder with an issue date and a review date for each document, plus a digital version in the same structure so that uploading to the procurement portal does not fail over a file name. Legal requirements differ between federal, state and individual authorities and they change; the individual case should be checked, if in doubt with legal advice. This article does not replace it.
What the website can contribute
The website does not win a tender. It works at three other points: before, when a property manager starts looking for a business at all; in between, when a procurement office wants to place an unfamiliar name; and alongside, when staff are needed for the maintenance crews. All three fail for the same reason if a site shows nothing but attractive private gardens: the business does not look responsible for grounds maintenance.
A business such as Viktor Waldbauer Garten- und Landschaftsbau in Nordstemmen works mainly in private gardens — sand-set slabs, terraces, cisterns, complete garden installations. Anyone moving from that starting point into grounds maintenance adds to the existing presentation rather than rebuilding it: a dedicated page for grounds maintenance, a dedicated set of references, a dedicated first contact. The private garden pages stay as they are, because they continue to carry the revenue that fills the summer.
Property types instead of a service list
Not lawn care, hedge trimming, leaf clearance — but housing estates, commercial sites, grounds of care homes, public green spaces, playgrounds, cemetery areas. People search for their property, not for your internal breakdown of services.
Orders of magnitude instead of client names
References from contracts rarely name the client, often for contractual reasons. Property type, area size, number of maintenance passes and contract term are quite enough — and more informative for placing the work than a name would be.
Make capacity visible
Crew strength, machinery, vehicles, service radius, reachability outside office hours. These are precisely the details procurement offices ask for as a self-declaration — on the website they appear voluntarily and answer the question in advance.
A named contact with a direct line
A property manager telephones; they do not fill in a form. Name, role, direct line and reachable hours for grounds maintenance belong visibly on the page, not in a general contact field at the foot of the site.
Then there is the first contact itself. An enquiry form that pre-qualifies asks different things for grounds maintenance than for a private garden: property type, approximate area size, desired start of service, existing contract with remaining term, contact and managing agent. Six fields are enough to see whether a site visit is worthwhile. The portfolio gallery gains a filter by property type, so that a housing association does not have to page through thirty private gardens to find one housing estate.
How to structure the grounds maintenance page
This page has a different job from a service page for private customers. It does not have to delight, it has to place: does this business fit this property, and is it able to deliver over years? That works with a sober order of sections that follows the reader's questions rather than the internal organisation of the business.
- An opening of two sentences: which property types are maintained, within what radius, since when — without marketing vocabulary
- Scope of work as an annual cycle: what happens from March to November, what in winter, what on call
- Property types as separate sections with three to five sentences each and one image from ongoing maintenance
- Capacity and equipment: crews, machinery, vehicles, cover arrangements for holidays and sickness
- How working together runs: site visit, measurement, quote with itemised positions, start of contract, a fixed contact
- References by property type with area size, maintenance passes and contract term instead of client names
- Records and qualifications as a list, with a note that documents are supplied on request
- A named contact with a direct line, and only then the form with property fields — in that order, not the other way round
Two additions are worth making. First a short section on winter maintenance, because commercial clients and housing associations like to award both to one supplier and will otherwise ask on the phone. Second a link to the careers page: whoever wins maintenance lots needs staff, and a landscaping job ad reaches applicants better when it is clear that the work means fixed rounds and predictable hours rather than changing building sites.
Six steps to a first maintenance lot
Moving into grounds maintenance is not a campaign but a winter task. The following steps can be worked through between November and February, that is, in the period when the crews are less stretched anyway and the tenders for the coming season are published.
Determine capacity honestly
How many hours per week are reliably available across the whole season once the running construction projects are deducted? That figure is the ceiling for all lots together, not for each one. Exceed it and you lose the site in the second year, and the reference with it.
Assemble the records folder
Gather every document from the suitability section, note the issue date, set a review date. In parallel, register on the state procurement portal and set the interest profile by service area and district so that notices arrive automatically.
Prepare the references
From existing maintenance work, describe three to five references with property type, area size, number of passes and contract term. Take photographs during ongoing maintenance, not only of the finished state — a working crew tells a commercial client more than an empty lawn.
Build the grounds maintenance page
Put the material from steps one to three into the website, separate from the private garden pages, with a named contact and a property form. This page is the address every later application, letter and business card points to.
Approach clients directly
List the property managers within your service radius and write to them over winter — with a reference to their property rather than a standard letter. Housing associations often award a year ahead; a letter in January meets the planning for the spring after next better than one in April.
Choose a small first lot
The first property should lie within the familiar radius and should not stretch the crew. The aim is a clean first season with complete documentation — that is what produces the reference needed for the second, larger lot.
Keeping a site costs less than winning one
The most demanding part of grounds maintenance is getting in. An existing contract is frequently renewed tacitly or continued after a brief review — provided there were no complaints and the documentation holds up. Conversely, a business that loses a site rarely loses it on price, but on unanswered calls, dates moved without notice and missing records. That is the good news, because all three are matters of organisation.
In concrete terms: a service record per visit, in the simplest case a short note with date, crew, items carried out and anything noticed. Once a year a joint inspection walk with the managing agent, producing minutes and, where appropriate, suggestions for the following year. And a contact who is reachable even when the owner is standing on a building site. Managing agents change contractors reluctantly, because every change means work for them — that circumstance works in a business's favour, as long as it is not squandered.
