Concrete core drilling involves extracting cylindrical samples from solid concrete using specialised drill bits. Getting precise quotes is important for planning budgets and timelines. This article provides tips for attaining comparable quotes.
When is it Needed?
Typical scenarios include building refurbishments, holes for cables, waste pipes and ventilation such as extractor fans/aircon units, bollard/handrail installations and foundation investigations beneath existing structures.
What to Specify
Detail the site location, core hole positions, quantities, depths, and diameters. Specify core sampling requirements plus timescales. Requirements include access routes, traffic management plans, risk assessments and health and safety precautions.
Requesting Quotes
Source several approved contractors then request a minimum of three fixed written quotes. Clarify inclusions such as power requirements. Highlight any complex factors early on and allow time for contractor surveying.
Case Study
A retail unit upgrading required services relocating through floors and walls across multiple floors. Contractors surveyed and provided fixed quotes, with the lowest missing key outcome specifications, resulting in project delays and additional costs.
Comparing Quotes
Cross-examine prices versus timescales, flexibility, and sampling feedback timeframes. Compare contractors’ proposed rig suitability, experience, and safety standards with accreditation quality assurance.
Additional Costs
Seek clarity on potential variations such as out-of-hours and weekend works pricing. Ensure extra charges for busy areas such as London are understood.
Conclusion
Proper specification and attaining several quotes is essential. Highlighting project intricacies frontloads considerations into pricing. Discussing quoting processes with contractors boosts project comprehension on both sides.
