1. General Description of Works

The project is to provide a feasibility report, then based upon the output of the report, an approved 100% design and firm price construction cost sufficient to complete all pre-construction engineering designs, managing site clearances, installing the pad foundation network, and delivering fully commissioned utility connections up to the building’s internal termination points.

2. Requirements

Project Objective The objective of this contract is to provide all pre-construction engineering, design, site preparation, substructure installation, and utility servicing required to fully facilitate the installation of a new, single storey modular building. Upon completion, the structure will function as a community hub housing a library and café.

The completed works must be fully compliant, structurally sound, fit for purpose, and ready for immediate modular building installation.

Pre-Construction, Design & Survey Requirements

• Complete all comprehensive topographical, boundary, and level surveys required to establish definitive datum points and dimensional accuracy for the modular building footprint.

• Execute all necessary intrusive and non-intrusive ground investigations including dynamic sampling, borehole testing, and trial pits, to produce a conclusive geotechnical report for the foundation design.

• Conduct all necessary soil sampling and Waste Acceptance Criteria (WAC) testing to accurately classify, manage, and legally dispose of all surplus excavated materials off site.

• Perform a comprehensive buried services trace, utility mapping exercise, and CCTV drainage connectivity survey to verify the exact location, condition, and capacity of all existing infrastructure.

• Procure all mandatory statutory utility records and secure all necessary technical approvals prior to the commencement of physical works.

• Produce a detail, and sign off on all comprehensive structural substructure designs, pad foundation layouts, and gravity fed drainage networks.

Earthworks & Sub-Base Engineering

• Execute all bulk excavations to the definitive depths required to achieve the final design formation levels, ensuring the removal of all structurally unsuitable subsoil.

• Dispose of all surplus excavated materials, inert waste, and site arisings to a licensed off site tipping facility.

• Supply and install a high-performance geotextile separation membrane over the entire prepared subgrade to prevent material migration and protect the structural integrity of the subbase.

• Supply, spread, and mechanically compact a granular subbase layer (utilizing Type 1 or equivalent engineered aggregate) to the precise thickness and density required to safely support all construction and operational design loads.

Substructures, Structural Foundations & Plant Bases

• Design, supply, and pour mass concrete to all structural foundation bases.

• Supply and install heavy duty levelling piers/paving slab details to the exact structural dimensions and heights required.

• Design, supply, and construct a dedicated, level, base engineered to support the dimensions and weight of the specified air conditioning condenser unit.

• Supply and install all necessary perimeter skirting, to finish the building perimeter and protect the underside of the modular structure.

Foul & Storm Water Drainage Networks

• Excavate all drainage trenches to the depths and gradients required to ensure continuous gravity flow. Supply and install all gravity fed uPVC pipework, fully encased in a compliant granular bed, surround, and backfill material.

• Supply and install robust plastic inspection chambers at all mandatory change of direction and junction points, finished to final ground levels with appropriate load rated access covers to suit the surrounding traffic profile.

• Supply and install all required rodding eyes, rainwater pipe access gullies, and system accessories to deliver a fully functional, maintenance accessible network.

• Survey, locate, and form secure gravity connections to the existing on site foul and storm water manholes.

• Undertake all mandatory air pressure testing on the entire new drainage network.

Ducts & Utility Service Trenches

• Excavate all utility service trenches to compliant statutory depths and widths. Prepare and lay a protective sand blinding layer prior to utility installation and safely backfill and compact upon completion.

• Supply and lay continuous, flexible, general purpose utility ducts within the prepared trenches.

Water & Electrical Infrastructure Delivery

• Supply and lay a continuous MDPE water supply pipe within the service trench, routing it safely into the building footprint and terminating it at the designated internal connection point.

• Execute all necessary alterations and physical connections to the existing live water network.

• Chlorinate, flush, and pressure test the new water infrastructure.

• Supply, manage and coordinate the complete installation, testing, and live commissioning of the new electrical supply and final utility connections.

External Landscaping & Reinstatement

• Spread, level, and smoothly grade all retained on site topsoil over all areas disturbed by the construction works, ensuring seamless integration with the surrounding untouched area.
