Procurement of Green and Grey Area Maintenance
expertly prepared

We relieve your specialist department of the preparatory burden, prevent the typical pitfalls in the specification document, and bring sound market knowledge to your procurement.

Back to services overview

What makes a sound grounds maintenance tender — and what can go wrong

In outdoor area maintenance, quality issues do not appear after months — they often show up in the very first season: lawns are mown at the wrong time, hedges are not properly cut, weeds proliferate on paths, tree inspections are not carried out or not adequately documented. The latter is more than a cosmetic issue — the duty of care for trees gives rise to substantial liability for the contracting authority.

On top of this: the procurement procedure itself must be structured and documented — from needs analysis through specification to bid evaluation and award decision. Each of these phases ties up capacity in the procurement department and the building management, which still has to handle day-to-day business in parallel.

All of this can be avoided.

Three reasons why we are commissioned

01

Relieving the specialist department

Preparing a green and grey area maintenance tender — including survey of maintained areas and tree register compilation, definition of maintenance condition levels, bill of quantities, frequency and seasonal schedule, suitability requirements and procurement documentation — typically requires several hundred hours of specialist capacity. We take on this preparatory work in modular form, tailored to your needs. The decisions remain with you; we handle the demanding detail work.

02

Quality assurance in the specification

The most common problems in outdoor area maintenance — neglected maintenance condition, gaps in tree inspections, disputes over weather-related service interruptions, unclear delineation between routine and additional services — do not arise at contract signing, but later, because the specification had gaps or the maintenance condition levels were not clearly defined. Our specifications are structured so that it is clear which maintenance condition must be achieved on which areas in which season, how weather-related interruptions are governed contractually, and how poor performance is sanctioned. We close these gaps consistently, because we know them from many procedures.

03

Market knowledge and pricing insight

For years we have been supporting tenders in building services, and we understand how landscape maintenance contractors price their bids: which hourly rates and machine costs are realistic, where waste disposal costs are correctly applied, which seasonal peaks must be priced into the calculation, which bidder calculations are sustainable. We bring this knowledge into the bid evaluation — without recommendations for or against individual bidders, but with a technical assessment of which bids are sustainable.

Our services — modular and individually bookable

You decide which part of the process you keep in-house and where you bring us in. The following modules can be commissioned individually or in combination.

01

Needs analysis and baseline survey

Systematic recording of the areas to be maintained, broken down by category (lawns, hedges, perennials, seasonal planting, paths, squares) and maintenance condition level. Compilation or update of the tree register, capturing trees relevant to duty of care. Identification of optimisation potential — for example in mowing frequencies, ecological mowing design or irrigation systems.

02

Specification and bill of quantities

Preparation of a differentiated specification with a clear separation of lawn maintenance (mowing, scarifying, fertilising, irrigation), shrub and hedge maintenance (trimming, formative cutting, maintenance pruning), tree care and tree inspection (under FLL — Forschungsgesellschaft Landschaftsentwicklung Landschaftsbau, the German landscape research society — tree inspection guidelines), seasonal planting and perennial care, path cleaning, weed removal and joint maintenance as well as seasonal additional services (leaf removal, winter services). The bill of quantities is structured so that bidders submit comparable price calculations — including seasonal peaks, machine costs and disposal expenses.

03

Procurement documents and procedure support

Support in compiling the complete procurement documentation, technical input on the development of suitability and award criteria as well as the evaluation matrix. Technical support of the procedure through to the award decision — including communication with bidders, bid evaluation and technical assessment. In green and grey area maintenance, particular attention is paid to suitability evidence: certification under the German Plant Protection Act (Pflanzenschutzgesetz, PflSchG), tree inspection qualification under FLL guidelines, machinery and equipment provision as well as references for comparable properties.

04

Contract input with quality assurance mechanisms

Technical input to the contract document — so that topics such as maintenance condition definitions, weather-related interruption clauses, sanctions for poor performance, adjustment mechanisms for changes in area or maintenance level and clear responsibilities for points of contact are addressed in a practice-oriented way. Consideration of the binding sectoral collective agreement (Rahmentarifvertrag GaLaBau — landscape and gardening trade framework agreement) and the resulting pricing basis.

05

Quality measurement and acceptance

Definition of measurable quality criteria based on FLL maintenance condition levels and the technical requirements of your properties: achievement of maintenance condition, completeness of tree inspection documentation, response times to identified issues, green-waste disposal records. Establishment of control routines that work in practice during contract operations and do not turn the day-to-day acceptance process into an excessive burden.

06

Environmental and social criteria

Integration of environmental standards into the specification: insect-friendly mowing schedules and methods, avoidance of pesticides on public areas, near-natural maintenance concepts, promotion of biodiversity. Social standards — collective-agreement remuneration, provision of work clothing, language requirements — are likewise weighted as award criteria or formulated as binding minimum requirements, depending on your priorities.

07
Beyond contract award

Quality assurance and ongoing contract management

Our involvement does not end with the award. We support maintenance condition controls during the contract, the analysis of tree inspection documentation, the handling of defect notices and the structured escalation in cases of recurring poor performance. This keeps the contract sustainable over its full term, and remediation happens in a planned rather than reactive manner.

Advisory path

Restructuring mandates — when existing contracts no longer hold

A frequent reason for being engaged is not new tenders, but existing contracts that no longer hold: maintenance condition no longer matches expectations, tree inspections are not or not adequately documented, disputes over weather-related interruptions accumulate, seasonal peaks — leaves, winter services, mowing — are not reliably covered.

In such cases we conduct a contract analysis, identify the root causes of the difficulties and develop an approach — which can range from remediation within the existing contract through to a full new tender. The aim is a baseline that will hold for the years ahead.

Restructuring existing contracts is a distinct advisory path — for public sector and private sector clients alike.

Specialist insights

Technical specifics of green and grey area maintenance

A green and grey area maintenance tender differs from other service tenders in several technical respects, which we address in the specification and the contract:

Duty of care and tree inspection

Duty of care for trees is a central obligation of the contracting authority. We draft the requirements for tree inspection frequency, inspector qualifications (under FLL tree inspection guidelines) and documentation so that these obligations can be passed on to the contractor in a procedurally sound manner.

FLL standards and maintenance condition levels

The FLL maintenance condition levels provide the framework for outcome-based specifications — as an alternative or complement to pure frequency schedules. We use these levels as a reference, but tailor the specific configuration to your properties.

Seasonality and weather dependency

Unlike continuous services, the workload in green area maintenance is distributed seasonally — with peaks for mowing, leaves and winter services. Weather-related interruptions and additional efforts must be clearly governed contractually, so that disputes during contract performance are avoided.

Collective bargaining and certification

The Rahmentarifvertrag GaLaBau (landscape and gardening framework collective agreement) varies by region and is relevant in many procurement procedures. In addition, certification under the German Plant Protection Act (Pflanzenschutzgesetz, PflSchG) is required for anyone applying plant protection products. We reflect these requirements in the specification and in the assessment of bid pricing.

Ecological maintenance concepts

Insect-friendly mowing, avoidance of pesticides, near-natural planting and biodiversity-supporting maintenance measures are no longer just a bonus, but a standard requirement in many tenders. We anchor these requirements so that they are concrete and verifiable — not merely a general statement of intent.

Frequently asked questions

Frequently asked questions

What requires particular attention in grounds maintenance tenders?

Area-accurate specifications with defined maintenance intervals, seasonally adjusted service schedules and clear winter service provisions. Without an area register and condition documentation, disputes over scope and quality standards arise regularly.

Can grounds maintenance be tendered together with other services?

Yes. Bundling with winter services or routine cleaning is possible and can yield economic benefits. The key question is whether the market has sufficient providers capable of delivering this combination professionally — this should be assessed in advance.

How can quality in grounds maintenance be made verifiable?

Through defined maintenance targets (e.g. grass height, cutting frequency), site inspection protocols, photographic documentation and contractual response times for defects. Quality assurance must be built into the specification — retrospective agreements rarely hold.

What does procurement support for grounds maintenance cost?

This depends on the total area, number of sites and complexity of the procedure. In a no-obligation initial consultation we will give you a transparent estimate of scope and cost.
