SERVICES
REPRESENTATIVE PROJECTS BY THE AMERICEC TEAM This project comprised the preparation of a planning study, preliminary designs, and detailed designs for the improvement of the Dhahran Core Area Roads. The scope activities included site visits, data collection and field verification, site and road designs, site grading and drainage, marking and traffic signage, planting and irrigation, utilities relocation, site electrical and lighting, detour access, calculations, material take-offs, construction specifications, construction scope of work, coordination (including interface facilities and utilities), QA/QC, and project management. The project components included Al Munirah Road, Dhahran Boulevard, Loop Road, and Sixth Street, as well as Al Munirah Parking reconfiguration, Al Munirah Gatehouse, and support facilities. Urban upgrade features included significant improvements to parking and pedestrian movement with walks, grade separated pedestrian access, drop off areas, etc. Streets, walks, parking, recreational facilities inside Al Munirah Camp were revised and upgraded to include improved traffic movement, new security access and perimeter, new courts/fields, commissary, etc. Study aspects included vehicle field counts, traffic studies, and traffic modeling for all of Dhahran, particularly the roads and intersections directly affected within the main core area. Alternatives were developed and assessed, and recommendations were prepared. The project also included reviews and upgrades to the overall access to Dhahran, particularly to the west, and the inclusion of the North Park/Old Abqaiq Road into the overall security perimeter of Dhahran. To do this, the entire security perimeters and levels were reviewed and new external security gates, along with all the support facilities, became part of the project. Traffic Improvements and Beautification of the Commercial District – Dammam Municipality The project addressed the urban image of the commercial area and traffic improvements for areas of Dammam under 4 phases, namely concept study, preliminary design (PD), final design (FD), & preparation of contract documents. The scope covered traffic & pedestrians study, urban planning, beautification/landscaping, road design, stormwater drainage, lighting, sidewalks, signage, and proposed treatment of buildings. The concept study phase included data collection, field verification, topographic survey of sub-areas, traffic & pedestrian counts, concept/alternatives (bridging/crossing arterials, urban open spaces, & vehicular circulation patterns). The PD phase included traffic & pedestrian improvements, parking lots, utilities, and recreation areas. The FD phase included preparation of construction drawings, coordination, and design for the relocation of existing utilities, technical specifications (CIS format), BOQ, conditions of contract, and project management. Currently construction supervision is being provided. Facilities included urban commercial streets, upgrade of 13 intersections to grade separated intersections along three main arterial streets (King Fahd Road, 42nd Street, and Abdulaziz Street), as well as at other individual locations. The work included complete traffic and urban street design for interconnecting street lengths between intersections. Conceptual design alternatives were developed to evaluate improvements to traffic movement. Design accounted for and accommodated all existing buildings and business activities, elevations, curb cuts, bollards, traffic controls, parking and other street related activities. The design activities also covered signage (street/traffic/informational) and lighting (street/pedestrian). Urban amenities included bus stop shelters, taxi ranks, hardscape (all pedestrian stripping, curb cuts-handicapped/wheeled access), planting/irrigation, & street furniture. Waste handling addressed normal and heavy commercial streams for appearance and efficiency. Road rehabilitation included revision to circulation patterns, one way streets, road channelization, dual carriageways by use of variable aligned one ways, complete treatment of urban cross-section/urban renewal, new paving & vertical alignment for drainage. Treatment of alley ways for pedestrians or traffic was also included. Access Road to Shaybah Oil Field Development – Saudi Aramco This project comprised the necessary engineering services for upgrading the existing Shaybah Road including preliminary design (PD)(data collection, site visits, engineering data analysis, utilities investigation, geotechnical investigations, drainage study, preliminary design drawings, material takeoff, budget estimates, and project proposal report), and final design (FD) (detailed engineering drawings, specifications, calculations, material takeoff, QA/QC, & project management). Project included road and intersections design, marking and signage, road drainage, communications, and lighting. The Shaybah Road is a 400 km two lane foam asphalt paved road providing access from Salwa, KSA, to the Shaybah Oil Field. In phase 1, and to meet tight budget constraints and client expediting requirements, the original road was designed in 1996 and constructed in 1997 as a marl road to provide access for construction related equipment and materials for production facilities, including GOSPs, pipelines, and construction camp at Shaybah Field. The original road design accommodated special considerations for difficult terrain (sabkha, 300 m high sand dunes), locations of suitable materials, water wells, climate issues, contractor camps, vehicle maintenance facilities, etc. In phase 2, and to minimize continued maintenance, the road was foam asphalt paved. Eventually, and in phase 3, once additional budgets were made available, an evaluation of the entire road length was undertaken to cover several factors that included pavement quality and associated ride quality, and design speed increase from 80 km/h to 120 km/h. Pavement quality and ride quality were analyzed through a series of visual surveys which catalogued the type and severity of pavement distress including rutting, bleeding, raveling, patching, and various types of cracking. Pavement information including sub-base and structural data, maintenance overlay data, and Traffic Index data were also reviewed. Various alternatives for pavement upgrades were developed, including milling and resurfacing, recycling and reclaiming, reapplication/use of foamed asphalt, and determination of resurfacing thicknesses required. The upgrade requirement from 80 km/h to 120 km/h necessitated a realignment of the vertical and horizontal curves over 80% of the road to meet the increased speed values. The upgrade also included associated utilities investigations, geotechnical investigations, and drainage studies. Saudi Aramco Hawiyah Gas Plants Site Preparation and Access Roads – Hawiyah, Saudi Arabia This project comprised planning studies/investigations, preliminary design (PD), final design (FD) package, technical support to the PMT, & geotechnical investigations. The project provided for the development of site preparation for Hawiyah Gas and NGL Plants, along with the corresponding access roads (~80 km). The work also included construction support activities as requested by the Saudi Aramco PMT, covering material reviews and approvals, shop drawing reviews and approvals, responses to technical queries from the contractor, site visits, & coordination meetings. The preliminary design comprised data collection and site visits, traffic studies, road alignment, surveys, design criteria, and preparation of the project proposal report. Detailed design included road geometric design, drainage, road marking and signage, intersection design, cross sections and details, construction specifications, construction scope of work, material take-offs, calculations, cost estimate support, QA/QC and project management. The road planning studies identified requirements for a new road segment (Hawiyah Access Road - 66 km from Al Hasa to the Gas Plant to support employee access), the upgrade of an existing road segment (Central WIPs Road - 22 km link), and a tie-in to an existing Government road (Haradh Road). The central WIPs Road required the detailed review of the existing road, including pavement section, pavement width, alignment (vertical and horizontal), consideration of crossing roads, existing intersections, utility crossings (hydrocarbon pipelines and power lines), and overall traffic safety considerations per the new anticipated traffic volume generated by the link, particularly truck traffic (general commercial, and gas plant related). The design of the Central WIP’s Road included new/upgraded pavement sections, intersections, intersecting road closures, selected widening, modifications to sub-standard horizontal and vertical alignments (30% of road), and modifications and requirements for utility crossings per required Saudi Aramco and Sceco standards (the transportation portions of which are essentially based on AASHTO standards). Traffic and GIS Applications – Goodwill Grivas, MI Responsible for the development of a GIS system which included inventory and modeling infrastructure such as roads, traffic, drainage, sewerage and electric systems. Saudi Aramco, Abqaiq Plant Entrance Upgrade Study and Preliminary Design – Saudi Arabia Managed the technical aspects, quality control and design development for the upgrade of an existing complex. Included within the project’s scope is the study, planning, and design for streets, access, and parking for Abqaiq.
