A week of slippage flagged a month ahead can be absorbed; the same week flagged the day before cannot. That is why there is a named site manager, measurement records by phase and a photographic record, which make slippage visible while there is still time to correct it. What structure does not forgive Concrete and steel accept correction while the next phase has not started. After that, correcting costs the whole job, which is why dimensional control closes each phase before the next begins. Work at height with a written plan Façade and roof concentrate the risk on a site. The access plan and fall-arrest system are set before the team goes up, not improvised on the day. The ground decides the surprises Earthworks, drainage and service roads generate almost every unforeseen cost. They are surveyed before the quotation, not halfway through. 01 manager per site Construction & Refurbishment ## What is guaranteed in writing ### In-house site management One named person responsible per site, from start to handover. ### Safety coordination Site signage to legal standard, with prior notice to the labour authority. 25 years warranty ### Works records Photographic record, measurement records and testing delivered at the end. 22% minimum efficiency ### Full contract or specialist package We deliver the complete works or come in as a specialist subcontractor.

See detail → In detail ## What sits behind each one 01 ### Structure The structure is the part you cannot correct later. Concrete, steel and masonry follow execution control with material testing, and anything outside tolerance is redone before the next phase starts, not at the end, when the correction affects the whole job. - Material tests with records, not with declarations - Dimensional control at each phase, before the next one begins - Measurement records that allow the work to be checked months later 02 ### Finishing and façade Finishing is where the job is judged by eye, and it is also where work at height concentrates the risk. Cladding, insulation and façade are executed with fall-arrest systems and with the access plan set before the team goes up. - Work at height with fall-arrest systems and a written access plan - Insulation checked for continuity, not only for thickness - Photographic record of everything the cladding will cover 03 ### Groundworks Earthworks, trenches, service roads and drainage drive almost every unforeseen cost on a site. That is why the survey comes before the quotation, and why anything that changes is flagged before it happens. - Ground survey before the quotation, not halfway through the works - Drainage sized for the actual runoff at the location - Service roads built for the equipment that will actually arrive ## From first contact to documented handover 01 Project review Reading of drawings and specifications, plus on-site survey. 02 Quotation Bill of quantities and prices, with schedule and conditions in writing. 03 Site set-up Establishment, safety signage and prior notification of site opening. 04 Delivery Phased works, with measurement records and photographic record. 05 Handover Joint inspection, snagging and handover of documentation. Delivered works ## Installations that demonstrate our capability Structure under way, with work at height Site set up before the first work front opens Assembled structure, seen from above Precast concrete façade, accessed by platform ## Questions that deserve a direct answer Do you work as a main contractor? Yes, and also as a specialist subcontractor on another contractor’s works. Both forms are set out in the proposal. Who is accountable for the site? A named site manager, on the contract and on the site board, as the law requires. How is safety handled? With signage to EN ISO 7010 on site and prior notification of site opening whenever the works reach the legal thresholds of duration or headcount. What if the schedule slips? We flag it as soon as the risk is identified, with the cause and the recovery plan, not on handover day. Request a quote ## For projects that demand a proper standard. Tell us what you need.
