Ordering building materials is not only about finding the right product and agreeing on a price. For glass, aluminium, hardware and other construction materials, lead time and delivery planning can directly affect the progress of a project.
A contractor may have the correct window dimensions, approved glass specification and installation team ready, but if the materials arrive late, the programme can still be disrupted. This is particularly important when a project is outside Nairobi and materials must travel to locations such as Mombasa, Kisumu, Eldoret, Nakuru, Malindi or other upcountry destinations.
Glass requires additional planning because it is fragile and may need careful handling, suitable packaging and secure transport. Aluminium profiles can also require protection against bending, scratching and surface damage, particularly where long sections are being transported.
For procurement teams, the important question is therefore not simply, "How quickly can you deliver?"
The better questions are:
Understanding these issues helps contractors and clients plan purchases more realistically.
Ali Glaziers Limited supplies glass, aluminium, hardware, sanitary products, flooring and other building materials from its Nairobi, Eastleigh and Malindi operations, with delivery arrangements available for customers in Nairobi and other parts of Kenya.
For current product availability, buyers can browse the Ali Glaziers product catalogue before requesting a quotation.
Lead time is the period required between confirming an order and having the goods ready for the agreed delivery or collection point. Lead time is not necessarily the same as transport time because stock availability, fabrication, preparation, packaging and dispatch may all occur before the goods begin their journey.
This distinction is important when planning a construction programme.
Suppose a contractor needs aluminium windows for installation on Monday.
If the products are already available and ready for dispatch, the delivery process may be relatively straightforward.
If the windows need:
then the order has a production component before transportation begins.
The total procurement period can therefore be considered as:
Order confirmation + stock preparation/fabrication + packing + dispatch + transport + site receipt.
A contractor who considers only the transport journey may underestimate the actual time required.
Stock items are products currently available for sale in the required quantity, while non-stock or special-order items may require procurement, fabrication or supplier confirmation before dispatch. Always confirm actual availability and the required quantity before committing a project installation date.
Stock status can vary by:
An item appearing in an online catalogue does not necessarily mean that every variation is physically available at every branch.
For example, a particular glass type may be available in one thickness but require ordering in another.
Similarly, an aluminium product may be available in one finish but require additional lead time in a different colour.
This is why project teams should provide the supplier with the complete specification rather than simply asking for "glass" or "aluminium."
Before ordering glass, confirm the glass type, thickness, dimensions, quantity, finish, edge treatment and required delivery location. Fabricated or specially cut glass should not be ordered from incomplete dimensions because errors can result in wasted material and additional lead time.
For a glass order, provide as much information as possible.
A useful order schedule may include:
| Information | Example Requirement |
|---|---|
| Glass type | Clear, tinted, toughened, laminated or specified alternative |
| Thickness | Project-specified thickness |
| Length | Confirmed dimension |
| Width | Confirmed dimension |
| Quantity | Number of panels |
| Edge treatment | As required |
| Holes/notches | Where applicable |
| Finish | Clear/tinted/other specified finish |
| Application | Window, door, partition, shower, shopfront etc. |
| Delivery location | Exact project destination |
| Required date | Preferred delivery date |
| Contact person | Site receiving representative |
The more complete the information, the easier it is for the supplier to confirm feasibility.
Custom glass may require cutting, processing, tempering, laminating, polishing, drilling or other preparation before it is ready for installation. These additional processes mean that special-order glass should be planned earlier than readily available stock items.
Not all glass is simply cut and delivered.
Depending on the specification, glass may require:
Each additional process can affect the procurement schedule.
This is particularly important for large commercial projects where dozens or hundreds of panels may require different dimensions.
A small dimensional error can also have a major impact if the glass has already undergone processing.
For this reason, final measurements should be verified before fabrication where the project requires exact fabricated panels.
Stock items can often be prepared for dispatch faster than fabricated or special-order materials, but the actual timing depends on quantity, branch availability, order confirmation, payment or credit arrangements and delivery requirements. Suppliers should confirm the expected dispatch date rather than customers assuming that catalogue availability means immediate delivery.
There is no single lead time that applies to every stock product.
For planning purposes, construction teams can classify orders into three broad categories:
The required product and quantity are available and can be prepared for dispatch.
The main considerations are:
The material is available but requires:
The preparation period should be included in the delivery plan.
The product requires:
These orders should be planned significantly earlier.
The exact lead time should always be confirmed against the actual product and quantity.
A product may be available in small quantities while a large project order requires additional procurement or preparation. Large quantities should therefore be confirmed with the supplier before the contractor commits to an installation programme.
Consider a project requiring:
The supplier may have sufficient stock for the first requirement but need additional procurement for the larger quantities.
The same applies to:
For major construction projects, procurement should therefore be based on the total required quantity, not just the availability of one sample or small batch.
Long-lead materials should be identified during procurement planning because delays in specialist fabrication or sourcing can affect subsequent trades. Ordering early provides more time to resolve specification, quantity and transport issues before installation is due.
Long-lead items can include:
The project programme should identify these materials separately.
A simple procurement schedule can include:
| Material | Specification Approved | Order Date | Expected Ready Date | Delivery | Installation |
|---|---|---|---|---|---|
| Glass | Confirmed | Planned | Supplier confirmation | Scheduled | Planned |
| Aluminium | Confirmed | Planned | Supplier confirmation | Scheduled | Planned |
| Hardware | Confirmed | Planned | Supplier confirmation | Scheduled | Planned |
| Flooring | Confirmed | Planned | Supplier confirmation | Scheduled | Planned |
This gives the project manager visibility over potential bottlenecks.
Glass delivery requires more careful handling than ordinary hardware because panels can break, chip or scratch if improperly packed or secured. The transport arrangement should match the size, quantity and fragility of the glass being delivered.
A safe glass delivery process generally considers:
Glass should not simply be treated like an ordinary boxed product.
Large sheets require suitable support during transportation.
The loading arrangement should prevent:
For larger projects, the delivery and offloading method should be considered before dispatch.
Proper packaging reduces the risk of scratching, edge damage and breakage during handling and transport. Packaging requirements become increasingly important as glass panel size, weight, distance and handling complexity increase.
Depending on the order, protective measures may include:
The objective is to keep panels stable throughout:
Loading → transport → unloading → site storage → installation.
The risk does not end when the vehicle reaches the construction site.
Glass can still be damaged during movement from the delivery point to the installation area.
Upcountry glass delivery involves additional planning because distance, road conditions, transfer points, site access and offloading arrangements can increase handling risk. Customers outside Nairobi should provide accurate delivery details and allow sufficient time for transport and site coordination.
A Nairobi delivery may involve a relatively short journey from the supplier to the construction site.
An upcountry order may involve:
For example, a project in a town centre may have straightforward access.
A rural construction site may have:
The delivery quotation should therefore be based on the actual destination and requirements.
Building materials can be delivered beyond Nairobi, with logistics arranged according to the destination, product and order size. Exact delivery timing should be confirmed for the specific town, quantity, product and site-access conditions.
Ali Glaziers' stated delivery network includes Nairobi and destinations such as:
Delivery can also be arranged for other locations across Kenya depending on the product, order and logistics requirements.
For coastal customers, the Malindi branch at Imadi Shopping Mall provides an additional point of service.
For a specific glass delivery in Kenya, customers should provide the exact destination rather than only naming the county.
For example, instead of:
Deliver to Kisumu County.
provide:
Deliver to [project/site name], specific town or area, Kisumu County.
This allows the supplier to assess the actual logistics requirement.
Accurate delivery information helps suppliers plan vehicles, routes, offloading and communication with the receiving team. Incomplete addresses are a common source of delivery delays and additional coordination.
Provide:
A location pin can also be useful where appropriate.
For commercial projects, provide the site contact and gate or receiving instructions.
The site should be ready to receive materials before the vehicle is dispatched. Glass and other fragile materials should have a safe receiving area, appropriate handling arrangements and sufficient personnel available for unloading.
Before confirming delivery, check:
A delivery that reaches a site before it is ready can create unnecessary handling and storage risks.
For glass, this is especially important.
Repeated movement increases the opportunity for damage.
Glass should be stored in a stable, protected area appropriate to the product and manufacturer's handling requirements, away from activities that could cause impact or contamination. Storage arrangements should be planned before delivery rather than improvised after the vehicle arrives.
The site team should establish a designated storage area.
Avoid storing glass where it is likely to encounter:
Glass should also be protected from accidental contact with construction equipment.
Storage requirements vary according to the glass type and packaging system, so project teams should follow the supplier or manufacturer's handling guidance.
If a site cannot safely receive the goods, delivery may need to be rescheduled or alternative arrangements made. Customers should communicate site-readiness issues as early as possible because additional handling or transport arrangements may affect cost and timing.
Common site-readiness problems include:
For fragile products, forcing an unsuitable delivery arrangement is not a good solution.
A better approach is to coordinate with the supplier before dispatch.
Glass and other high-value materials should be checked promptly on delivery for visible damage, quantity and conformity with the order. Any discrepancy should be reported according to the supplier's delivery and returns procedures.
The receiving team should check:
Does the delivered quantity match the delivery documentation?
Is the glass the correct type and specification?
Where dimensions are measurable without unpacking or compromising packaging, confirm them against the order.
Look for:
Check whether protective packaging is intact.
Any concerns should be documented promptly.
Long aluminium profiles require protection against bending, twisting and surface damage during transport and handling. Profiles should be adequately supported and secured throughout the journey and unloading process.
Aluminium may be lighter than many other construction materials, but long sections can be vulnerable to damage.
Risks include:
This is particularly relevant to:
Packaging and support should reflect the profile length and finish.
Fabricated glass and aluminium should arrive when the corresponding openings, frames and installation areas are ready. Delivering fabricated components too early can create storage and damage risks, while delivering too late can stop installation teams from progressing.
This creates a procurement balance.
Potential problems include:
Potential problems include:
The best delivery date is usually linked to the project's installation sequence.
Glass should ideally arrive when the installation area, frames and access conditions are ready to receive it. Coordination between supplier, contractor and installer reduces unnecessary storage and handling between delivery and installation.
For a window project, for example, the sequence may be:
The exact sequence depends on the project.
The key principle is to connect procurement with installation.
Weather can affect loading, unloading, site access and safe handling, particularly for fragile or finished materials. Construction teams should maintain suitable covered storage and coordinate deliveries around site conditions where practical.
Kenyan weather varies considerably between regions and seasons.
Heavy rain can affect:
In coastal regions such as Malindi, humidity and the marine environment also make sensible storage and material protection important.
Weather does not necessarily mean a delivery cannot proceed.
It means the site should be prepared to receive the materials safely.
Longer delivery distances generally require more transport planning and can affect logistics cost, especially for bulky, fragile or high-volume materials. The delivery quotation should therefore be based on the actual destination and order rather than assuming one nationwide rate.
Transport cost can be influenced by:
A small glass order and a full project load may have completely different logistics requirements even when travelling to the same town.
Contractors can reduce delivery delays by confirming specifications early, ordering long-lead materials in advance, providing complete delivery details and ensuring the site is ready before dispatch. Clear communication is especially important for fragile or fabricated materials.
Use this process:
Confirm:
Ask whether the required quantity is:
Obtain the expected ready or dispatch date.
Provide the exact location and site contact.
Ensure access, storage and unloading are ready.
Check quantity and visible condition.
Protect the materials until installation.
This simple workflow can prevent many avoidable problems.
Splitting deliveries can reduce site-storage pressure and align materials with the construction programme, but it may also increase transport and handling requirements. The best approach depends on the project's installation sequence, storage capacity and logistics cost.
A phased delivery may be useful where:
For example, a large commercial development may not need every glass panel on site at once.
However, splitting deliveries requires coordination.
The contractor should know:
A delivery note provides a record of the materials dispatched and received and should be checked against the order. It helps procurement teams identify shortages, discrepancies and delivery issues promptly.
A receiving team should compare:
Purchase order → Delivery note → Physical goods.
Check:
For larger projects, delivery documentation should be retained with the project procurement records.
This is particularly useful when several deliveries are made over an extended construction period.
Business customers should retain appropriate tax documentation for construction purchases, and Ali Glaziers supports business clients with eTIMS-compliant invoices. Procurement teams should ensure their purchase documentation is consistent with their accounting and tax-record requirements.
For contractors, developers and other business customers, documentation can be just as important as physical delivery.
A procurement file may include:
Keeping these records organised helps with:
For 2026 business purchasing, eTIMS-compliant invoicing should form part of normal procurement administration where applicable.
Project specifications should make delivery responsibilities clear, particularly for fragile materials and specialist components. Where delivery, offloading, storage or protection is the contractor's responsibility, the tender documentation should say so clearly.
A specification can address:
This prevents disputes over whether a quoted material price includes only supply or also includes delivery-related services.
For large projects, the procurement documents should also identify whether delivery is:
A glass delivery plan should identify the material, quantity, delivery sequence, destination, handling requirements and responsible receiving team. Larger or more complex projects benefit from coordinating delivery dates with the installation programme rather than ordering materials in isolation.
A simple delivery plan can include:
| Delivery | Material | Quantity | Destination | Planned Date | Installation Stage | Receiving Contact |
|---|---|---|---|---|---|---|
| 1 | Glass | Confirmed quantity | Project site | Agreed date | Phase 1 | Site representative |
| 2 | Glass | Confirmed quantity | Project site | Agreed date | Phase 2 | Site representative |
| 3 | Aluminium | Confirmed quantity | Project site | Agreed date | Phase 3 | Site representative |
This gives everyone a common reference.
Fragile materials should be unloaded using a method appropriate to their size, weight and packaging, with adequate personnel and equipment. Rushing the unloading process can create damage even when the materials were transported correctly.
Before the vehicle arrives, confirm:
For large glass panels, the handling requirements should be determined by the product, size and manufacturer's guidance.
Do not assume that a delivery driver or supplier automatically provides specialist lifting equipment unless this has been specifically agreed.
Malindi customers should consider both transport and coastal site conditions when planning building-material deliveries. The exact delivery arrangement should be confirmed based on the product, quantity and destination, while the Malindi branch provides a local point of service at Imadi Shopping Mall.
For projects in Malindi and surrounding areas, consider:
Customers can also coordinate procurement through the Malindi branch where appropriate.
This can be useful for projects in:
Exact availability and delivery arrangements should be confirmed for the specific order.
Nairobi customers benefit from shorter delivery distances, but site access and traffic can still affect delivery coordination. Same-day delivery is available in Nairobi according to Ali Glaziers' stated service offering, subject to product availability, order confirmation and delivery arrangements.
Same-day service is most useful when the required product is already available and the order can be processed within the relevant operating and logistics window.
Contractors should still avoid assuming that every product can be delivered immediately.
A custom glass order, for example, may require preparation before it can be dispatched.
This is why the distinction between:
Same-day delivery
and
Same-day availability
is important.
The first relates to logistics.
The second relates to whether the product is actually ready.
Hardware delivery is generally simpler than glass delivery, but large or project-volume orders still require stock confirmation and transport planning. Grouping related hardware into a planned project order can help reduce procurement gaps and repeated site trips.
Hardware orders may include:
Some items are readily available.
Others may require confirmation or special procurement.
Contractors should provide the exact specification and quantity rather than relying on general product names.
For example, "locks" does not identify:
A precise order is easier to process accurately.
Developers can reduce logistics risk by identifying long-lead materials early, coordinating supplier orders with the construction programme and maintaining a procurement schedule. Delivery should be treated as part of project planning rather than as an activity that happens after purchasing.
A practical developer workflow is:
Design → Specification → Approval → Quotation → Availability → Order → Preparation → Dispatch → Delivery → Inspection → Installation.
Each stage should have a responsible person.
For larger developments, appointing a procurement or site logistics coordinator can significantly improve communication between:
This becomes particularly important where several suppliers are delivering materials simultaneously.
There is no single nationwide glass delivery time because availability, fabrication, quantity, destination and transport requirements all affect the schedule. Stock glass may be prepared faster than custom-fabricated glass, while upcountry delivery requires additional transport planning.
Same-day delivery may be possible for suitable stock orders within the available delivery network, particularly in Nairobi, but it should never be assumed for every glass specification. Confirm stock, quantity, order processing and delivery arrangements before relying on same-day delivery.
Custom glass requires additional preparation such as cutting, polishing, toughening, laminating, drilling or other processing, so it normally requires more planning than ready-stock material. The supplier should confirm the expected ready date for the exact specification.
Upcountry delivery generally requires more transport planning than a local Nairobi delivery because of distance, routing, site access and handling requirements. The actual schedule should be confirmed for the destination and order rather than estimated from distance alone.
Ali Glaziers serves customers beyond Nairobi, including destinations such as Mombasa, Kisumu, Eldoret and Nakuru, with delivery arrangements depending on the product and order. Customers should provide their exact project location when requesting delivery confirmation.
Glass should be securely supported, protected and handled using methods appropriate to its size, weight and type. Proper loading, restraint, transportation, unloading and storage all contribute to reducing breakage and damage.
If an item is not available in the required quantity, the supplier may need to procure, fabricate or replenish it before dispatch. The customer should obtain a confirmed availability and expected ready date before scheduling installation.
Ordering too early can create storage and damage risks, while ordering too late can delay installation. The best approach is to coordinate the glass delivery with verified opening dimensions, site readiness and the installation programme.
Yes, phased delivery can be useful where storage is limited or installation is scheduled in stages. The delivery plan should clearly identify each batch and account for any additional transport or handling requirements.
Inspect the delivery promptly and document any visible damage or discrepancy according to the supplier's procedures. Notify the relevant supplier contact as soon as possible rather than moving damaged material through the site without documentation.
The safest procurement strategy is to work backwards from the date the material is needed on site, allowing time for specification approval, stock confirmation, fabrication, preparation, transport and receiving. This is particularly important for custom glass, large aluminium orders and upcountry projects.
A construction material does not become "available" simply because it appears in a catalogue.
The actual procurement question is:
Can the specified quantity be ready, transported and safely received when the project needs it?
For stock items, confirm:
For custom glass, also confirm:
For aluminium, confirm:
For upcountry delivery, provide:
Do not build a construction programme around an assumed delivery date.
Build it around a supplier-confirmed procurement schedule.
