Pre-Construction Costing. Know your budget before you pay for it.

1Fast estimation, no upfront C.E. fees. Skip the expensive formal Cost Estimating appointment just to find out if your project is affordable.
2A real cost estimate from real experience. We cost your architect's plans using decades of on-site building knowledge, so the numbers are realistic, not guesswork.
3You see the full budget picture early. Know what you're in for, budget-wise, before you spend money on the next stage.
4Happy with the estimate? We take it further. If you're satisfied, we act as your main Principal Agent and assist with C.E. (Cost Estimating) work where required, all under one roof.

The Festina Lente Difference
Why is Festina Lente Consultants Different?
The Traditional Route
Normally, an architect or engineer sends architectural plans to a C.E. (Cost Estimating) firm. These firms charge expensive professional fees, and once appointed, the client is locked in for the full duration of the project.
The client often doesn't realise the long-term cost commitment until they're already deep into the process. The C.E. firm bills at professional rates for every stage, from initial estimates right through to final accounts.
Expensive. Locked in. Limited transparency.
The Festina Lente Way
Festina Lente provides a cost estimate on the same architect plans, for much less. Our clients get a faster, more cost-effective, and fully transparent view of what their total project will cost.
This gives you a realistic budget picture before committing to expensive professional fees. After the cost estimate, you can then appoint Festina Lente as your Principal Agent for the full project, keeping costs proportionate and manageable.
Affordable. Transparent. No lock-in surprises.
Professional fees don't need to cost you dearly. We offer a cost-effective alternative, not a formal PQS function, but a practical, hands-on approach backed by 15+ years of building industry experience.

How a commercial build comes together, from civils to completed structure
On Site
Project Progress Photos
An illustrative look at how we take a commercial project from cleared ground to a completed second floor in twenty-two days.
Illustrative sequence. The cards below are representative diagrams of a typical commercial build progression, not photographs of a specific project. Real site photos will replace these as live builds progress.
Days 1–2
Site Clearing & Setting Out
The site was cleared, stripped of topsoil and levelled, then the surveyor set out the building grid. Corner pegs and string lines established the exact footprint and datum levels before any ground was broken. Getting the setting-out right here protects every measurement that follows.
Days 3–5
Bulk Earthworks & Excavation
Excavators moved bulk earth to formation level and dug the foundation trenches to engineer-specified depths. Spoil was managed on site and trench bottoms were inspected and approved before steel and concrete went in.
Days 6–8
Foundations & Footings
Reinforced strip footings were set out, rebar cages tied, and starter bars left projecting for the columns above. Footing concrete was poured and cured. The load path from structure to ground is established at this stage.
Days 9–10
Ground-Floor Slab
Fill was compacted in layers, a damp-proof membrane laid, and the slab mesh positioned on spacers. The ground-floor slab was cast and power-floated to a level finish, giving a clean working platform for the structure.
Days 11–13
Columns & Ground-Floor Walls
Ground-floor columns were cast off the starter bars and the blockwork walls built up between them. Vertical alignment and plumb were checked continuously so the floors above land true.
Days 14–15
First-Floor Slab
Soffit formwork and props were set, the suspended-slab reinforcement fixed, and the first-floor slab cast. Props stayed in place through the cure to carry the load until the concrete reached strength.
Days 16–17
First-Floor Structure
With the first-floor slab struck, columns and walls for the first storey went up. The building reads as two storeys now, with services routing planned ahead of the next slab.
Days 18–19
Second-Floor Slab
Formwork was struck and re-propped at the next level, reinforcement fixed, and the second-floor slab cast, with the tower crane handling materials to height. The full vertical envelope is now defined.
Days 20–21
Second-Floor Structure
Second-floor columns and perimeter walls were raised off the new slab. The frame is topping out, and close coordination of trades kept the programme tight through the final push.
Day 22
Second Floor Complete
The structure reaches its completed second floor. Full three-level commercial frame, parapet cast, and the building weather-tight in structure. From cleared ground to topped-out shell in twenty-two days through tight Principal-Agent coordination.
